The Craniocervical Junction and Headache Disorders

CCJ-and-headache

 

  • Chronic headaches come in different types
  • The neck and headache disorders
  • The craniocervical junction, NUCCA, and migraines

Headaches disorders are among the most common conditions that people seek treatment from a doctor. While most people will experience a headache of some form,  there are those who develop chronic and repetitive bouts with headaches of different types.

Each headache has unique characteristics that help to make an effective diagnosis for effective treatment. However, when we look at the reality of a daily patient interaction, we see that people with these headache disorders can have traits that overlap. (Remember this point because this is something I’ll come back to later)

That makes these headaches  extremely burdensome on the patient, but it can also be challenging for a doctor or therapist to find effective solutions. The chronic use of medications has led to the emergence of medication overuse headaches as the third leading cause of chronic headaches in the United States.

Medication overuse headaches were once classified as rebound headaches because of the way headaches could come back with a vengeance after the pain-relieving effects of a medication wore off. It became re-classified in part due to the alarming number of patients showing a regression in their headache symptoms after prolonged and frequent use of medication. While the physiology of this disorder is widely unknown, it does show characteristics of physical dependency as seen with drug withdrawals.

As drug therapies become less effective for this subset of headache patients, there has become a growing need to identify non-pharmacologic strategies to help patients with headache disorders. For many of these patients, a possible solution might lie in the neck.

The Neck and Headache Disorders

Headaches caused by a neck problem are usually classified as a subtype known as cervicogenic headaches. People with cervicogenic headaches are usually those with chronic headache along that is associated with neck pain, whiplash, or a resistance to most medications.  Studies on chiropractic and cervicogenic headaches are mixed, but it is mostly accepted that these types of headaches can be responsive to traditional spinal manipulation [1].

The study of these headaches has helped us understand the neurology behind head and neck pain in general. There’s a lot of really sensitive anatomy in your neck. Structures ranging from the muscles, ligaments, joints, nerves, arteries, and nerves. Things like whiplash, concussion, and even sub-concussive head injuries can damage some of these structures causing pain receptors to fire into your brain stem.

The muscles in the deep part of the neck have been implicated in headache disorderrs

The muscles in the deep part of the neck have been implicated in headache disorders

That’s where things can get a little bit screwy. The area in the brain stem that gets pain signals from the neck also receives pain signals from the head and face too! When nerve fibers from different parts of the body converge onto one location called the trigeminocervical nucleus (TVN), it allows for 2 things:

  1. It allows dysfunction in what part of the body to be felt in other parts of the body. It’s like when you have a pinched nerve in your back but you feel it in your leg, or when someone has a heart attack, they may feel it in their left arm.
  2. It allows the opportunity for treatments in one part of the body to have the ability to reduce pain in other areas. i.e – targeting TMJ and the neck to help with head pain

But What About Neurovascular Headaches Like Migraine?

Neurovascular headaches are those attributed to problems in the blood vessels in the head or brain. Migraine and cluster headaches are the main classes of chronic neurovascular headaches.

From a basic science standpoint, the neck still seems to be a problem area for migraine patients. We also know that patients with migraine also tend to have overlapping pain in parts of their neck too. However, from a clinical research standpoint, most studies on treating the neck in migraine patients have been underwhelming.

Findings like these challenge my beliefs because while I know the research says that treating the neck is not likely going to get you far, the results in my practice seem to dispute that.

The Cranialcervical Junction and Headaches

As an office focused on upper cervical chiropractic, we often see headache patients who have chronic and treatment resistant headaches. They’ve usually been through multiple rounds of different medications and have bounced around through various specialists from renowned neurologists, to local chiropractors.

Despite seeing these patients with significant challenges, our success rate in chronic migraine headache is pretty high. About 85% of our patients with a primary complaint of migraine headache reported a favorable outcome after 8 weeks on a progress exam.

 

How I imagine Brad Pitt would react if he had chronic migraines and didn't anymore

How I imagine Brad Pitt would react if he had chronic migraines and didn’t anymore

Of course I wish everyone got better, and I spend a lot of time reading and going to seminars trying to get answers for the other 15%. We just have a high degree of confidence that even some of the most challenging headache cases seem to do well when we address the upper neck.

If so many people get relief in our office, but clinical trials on chiropractic show limited effect, then what gives?

The big thing is that I don’t practice the same way that most chiropractors practice. Our office uses precise x-rays of the top of the neck called the craniocervical junction and we use very low-force techniques like the NUCCA procedure to address the neck. We also take pre and post x-rays to verify that we’ve changed the way the head sits on top of the neck.

  • Maybe previous chiropractic studies didn’t use techniques that accurately identified the problem area in the spine?
  • Maybe the way the spine was manipulated was not well suited to the specific patients?
  • Maybe the adjustments used didn’t actually show a structural change in the craniocervical region? It’s hard to say.

However,  a small 2015 study on patients suffering from chronic migraine headaches showed that the correction of the atlas vertebra using precise upper cervical methods showed a reduction in headache days and high patient satisfaction.

Obviously we can’t generalize these findings to every migraine patient because there was no control group and migraine studies have a high rate of placebo, but this is clearly something worth studying more.

Is It Worth It?

So I can’t tell someone if getting their atlas corrected is going to be worth it. For many people, the prospect of having far fewer headaches is worth any price. For others, you may have become so used to having headaches that you have learned to live with it and don’t mind the pain.

What I can say is that getting the atlas corrected through the NUCCA procedure is a really safe way to address some of the real anatomical and physiologic causes of many headaches.

The only things I can say for sure are this:

  1. If your atlas is a major cause or contributor to your headache syndrome, we’ll know it pretty quickly as you will likely respond to this within a few weeks.
  2. We will do everything in our power to help you find solutions to this disabling secondary condition, even if it means we have to refer you to another provider that is better equipped to help.

A Letter to My Patients – A Doctor’s Migraine Experience

A letter to my patients

 

To all of my patients and those soon to be,

In my 7 years of practice, I’ve had the honor of taking care of many of you when you have suffered from a variety of terrible health conditions. Thank you for putting your trust in myself and my staff.

Don’t worry, this isn’t a farewell letter. I’m not going anywhere anytime soon.

This is a letter to let you know that for all the trust you have placed in me to take care of you, I don’t think I was serving you to the very best of my abilities.

Don’t worry, it’s not because of a lack of training or ability to give a great atlas correction. I will always stand by my work there.

It’s because until recently, I don’t think I was able to truly understand what many of you have felt on a daily basis. It wasn’t until I got a taste of the throbbing pain and the nauseating sickness of a migraine that I could feel a deeper sense of connection to what some of you have felt for years.

Throughout my life I’ve always been fairly healthy. I’ve had some of the headaches, stomach aches, and shoulder injuries but these problems came and went without much assistance from other doctors. Even my introduction into chiropractic was less about treating any pain or symptoms, it was really about correcting the structure of my spine so I could experience what it was like to have optimal structure and better health.

Last month I got sick for the first time in several years. I can’t even tell you the last time I had a cold. I got hit with a terrible fever for 24 hours after a light workout. I came home to a feeling of chills followed by a long night of sweats and a 103.5 degree fever.

After a restless night of sleep, I noticed that I still didn’t feel quite right. I went into the office the next day in a daze that I couldn’t shake. That afternoon, the headache hit. My head started pounding and just the normal light and sounds of the office seemed to overwhelm my senses. I was nauseated and the only thing that seemed to be less terrible was just to put my head down and close my eyes.

I made it back home and just lied down in the dark. I didn’t want anything to drink, and I didn’t want any dinner (which if you know me, then you know this has to mean that I was in bad shape). It was too late to see my chiropractor, and anti-inflammatories didn’t really budge the pain.

All I could do was close my eyes, endure, and wake up tomorrow with the hope for a better day.

The next day I got to wake up feeling a little hung over, but after getting an adjustment from my chiropractor I bounced back to my normal self pretty quickly.

A lot of people don’t get to have that luxury, and I feel for them.

I’ve always known intellectually that living with chronic pain and illness must be a terribly difficult existence. However, it’s difficult to feel that struggle until you’ve experienced a taste of it for yourself.

I will always strive to improve my skills as a clinician to deliver the best care I possibly can to my patients. And even though I’ve often praised for my bedside manner, I think this short but temporary bout with the debilitating feeling of a migraine will make me a better and more compassionate doctor for you all.

Sincerely,

 

Jonathan Chung, DC

 

Why Pain Can’t Tell You Where You Need Treatment: A TMJ Case Study

TMJ and neck

Jaw pain/TMJD is a very frequent problem we see in the office. It’s so frequent that I spend one day each week inside of a dental office in West Palm Beach doing consultations with a great local area dentist that specializes in pain syndromes of the jaw.

Most of the patients that see us with jaw pain have already seen a variety of jaw specialists. They’ve had MRI’s done, mouth pieces made, and various therapies done on the area of pain.

The problem of course is that pain, especially chronic pain, does a poor job of telling us what is wrong with you. Chronic pain is complex. Chronic pain is misleading. Chronic pain is also a poor locator for pathology.

Identifying the Pain Source

One of the common questions asked during a case history is to highlight or point to the area where you feel pain. It can be useful sometimes when pain patterns are reflecting specific nerve roots, and it also gives a general vicinity for a doctor to examine more closely. For most cases of chronic pain, examining the area of injury often leads to dead ends. There’s no damaged tissue to treat or remove that’s likely to explain why someone hurts.

Patients with TMJ pain frequently seek the treatment of these specialized dentists, and most of them do really well when in the right hands. However, sometimes jaw pain isn’t truly a problem in the jaw. Sometimes it’s a pain problem somewhere else in the body.

I recently took care of a patients who were was referred by another chiropractor. The patient had been to 6 different jaw and mouth specialists but could not get any form of relief from treating the jaw.

When we examined the patient, we didn’t pay much attention to the jaw itself. The patient already had imaging and tests done to their mouth already, so I wanted to spend my time elsewhere.

We found that the patient had poor motion in their shoulder and neck area on the right side. They were also showing a large amount of forward head posture characteristic of anterior head syndrome. Surprisingly, the patient’s jaw seemed to move pretty well. There wasn’t the clunky abnormal opening and closing of the jaw that you would usually see in a TMJ where the jaw displays a large side to side movement. From my view, the patient’s jaw movement looked really great, but the patient’s neck was moving poorly.

Correct the Neck and Pain Self-Resolves

We did our normal protocols with this patient. We did a gentle NUCCA correction to the patient’s neck. We post-x-rayed the neck to verify a neck improvement, and then we waited. You can see the x-ray results below.

Pre and Post X-ray shows a small shift, but an almost perfect correction.

Pre and Post X-ray shows a small shift, but an almost perfect correction.

3 days after her first appointment, we had our first follow-up appointment scheduled. The patient had gone 3 consecutive days without any jaw pain at all for the first time in 2 years!

Pretty good, but would it last?

3 months later, we re-examined the patient. The patient was now going 1 month between appointments because it would be important to see if the patient could go that long a distance between appointments without pain. The jaw was still moving normally, but now their head and neck could move in all ranges of motion smoothly. The patient also stopped showing a persistent right tilt of their head.

Most importantly, the patient could now talk with no restrictions, and had no more food limitations on what she could eat. For all intents and purposes, she became a normal teenager again.

Final Thoughts

Now if we had kept on trying to treat the jaw and identify pathology in the jaw, would she still have gotten better?

It’s hard to say, but after 2 years of doing every jaw therapy under the sun, it just seemed to make sense to look at other pieces of anatomy.

The complexity of chronic pain often means that we can’t look at things linearly. We have to know that someone has pain in one region, but we also have to think about all the different anatomy that shares a connection with the part of the body that hurts. This doesn’t mean that every person with chronic jaw pain will get better from a neck adjustment, because that’s not true either.

It means that we have to take care of people and see them for what they are globally instead of treating them as an object with a specific piece of meat that hurts today.

Why Does Fibromyalgia Occur in Rheamatoid Arthritis – a Neurological Perspective

Rheumatoid Arthritis and Fibromyalgia

When working with a large number of patients with chronic pain and illness, you begin to notice patterns in relationship to certain illnesses. One of the more common trends I see today is the association between having an inflammatory illness like rheumatoid arthritis along with widespread body pain like fibromyalgia.

Rhumatoid arthritis and fibromyalgia share some commonalities in that they disproportionately affect women more than men, are associated with flare ups of increased pain intensity, and are chronic illnesses with no cure. Although they are separate and distinct health issues, it seems that if you have an inflammatory illness like rhematoid arthritis, 10-15% of these patients are likely to report the widespread body pain of fibromyalgia. Let’s see if we can break this phenomenon down.

Rheumatoid Arthritis and Inflammatory Illnesses

Rheumatoid arthritis falls into a class of inflammatory disorders where flare ups of inflammation can create damage to joints throughout the body. The pain from these flare ups can be debilitating, and the damage done to the joints can be quite severe when left untreated.

CanStock Photo

Notice the deformity of the thumb and index finger on the right hand. CanStock Photo

The damage to these joints is caused by an autoimmune reaction. Autoimmune disease is a condition where the body’s own defenses inadvertently create harm to the body itself. In the case of rheumatoid arthritis antibodies can build up in the joint spaces and cause other immune cells to create an inflammatory reaction in the area. This is where people can feel the heat, swelling, and pain that is known to occur in flare ups.

Patients with rheumatoid arthritis tend to have arthritic flare ups affect joints like the hands, toes, and neck. However, they are also more prone to wide spread pain in other regions not associated with arthritic breakdown. Why would pain exist in an area that is not associated with inflammation and destruction of the joint?

Chronic Pain: Central  Mechanisms

Pain is an extremely complex phenomenon. We generally think of pain having a direct relationship to tissue damage. When we get a cut, sprain an ankle, or break a bone we expect that pain will occur because of the injury. Therefore it’s not surprising that the pain and destruction from a rheumatoid arthritis attack to be very painful.

However, we also know that pain can occur long after an injury has healed, and even in the absence of injury whatsoever. This is what happens in patients with the widespread pain of fibromyalgia. People with fibromyalgia often have nothing to point to as a cause of their pain. It’s an enigma that makes chronic pain syndromes so frustrating because they have no test or image to prove why they feel so poorly.

Many suspect that this widespread body pain may be from dysfunction at the level of the central nervous system. In normal circumstances, the brain has a few ways of controlling how much pain it will feel.  This ensures that our bodies don’t overreact to normal everyday stimuli and interpret as painful.

One mechanism is by pain inhibition. Pain inhibition involves the brain using it’s own pharmacy of pain killing chemicals to stop a pain signal from going up the spinal cord.

Pain can be inhibited by chemical pathways inherent in the brain.

Studies on patients with rheumatoid arthritis have shown that the brain’s ability to inhibit pain becomes compromised leading to an increase in pain with normal stimulation. [Source]

Pain Inhibition broken

When your brain has difficulty inhibiting pain, then you begin to feel it in places where there’s no injury

Another way that the brain can modulate pain is through a concept known as the pain gate. The pain gate operates on the idea that pain has to hit a certain threshold for it to be consciously perceived in the brain. In this way, it allows the brain to ignore things that aren’t causing much damage or risk.

In a perfect system, you would only feel pain when you have actually created injury or are under imminent threat of injury. However, this appears to be another mechanism that gets disrupted in chronic pain patients. When people have chronic pain, it probably means that the gate that is meant to block most of your pain is letting everything in.

Pain Gate Theory

 Does Rheumatoid Arthritis Break This System Down?

The main treatment for inflammatory arthritis focuses on managing inflammation. Most patients with this type of arthritis will take a wide variety of anti-inflammatories that cover a wide spectrum. They include drugs that specifically target the inflammation associated with RA like Trexall, immune modifying biologics like Humira, and go all the way down to non-steroidal anti-inflammatories like ibuprofen.

In many of these cases, the inflammatory pain of arthritis is under control by these drugs, yet the widespread body pain persists. We don’t really know how or why these inflammatory disorders can lead to pain sensitization, but studying other acute pain conditions may give us some clues.

Studies done on patients with acute pain from a traumatic injury and post-surgery pain issues. When someone suffers from the pain of a major injury, the neurons associated with the pain response start to fire more frequently to guard against the area of injury. This is only supposed to be a short term response to significant injury, but in some cases these changes become persist through a phenomenon known as plasticity. When these spinal cord neurons stay hypersensitive, it means that a person’s nervous system will become hypersensitive to the pain response. [Source]

While inflammatory arthritis isn’t necessarily an injury in the classic terms, make no mistake that inflammation can create a significant amount of tissue damage when it goes unchecked.

Making Your Nervous System Less Sensitive

If the nervous system can be made more sensitive by persistent pain, can it work in the opposite direction? A lot of the research on pain has been focused on targeting these mechanisms which has lead to a higher usage of opioid medications. The obvious problem is that opioids are highly addictive and has become a major public health issue.

There is a growing need for non-pharmacologic interventions to address these chronic pain issues, and fortunately there are some that can be really effective. In cases of chronic pain, the best approach is one that addresses a person from a mental and physical standpoint rather than chasing after a holy grail treatment.

When you look at the pain gate theory image, you can see that the factors that impact your pain threshold include brain and spinal input which exercise and chiropractic adjustments can play a major role. Things like memories, emotions, expectations, and attention are all factors that can be changed with neuropsychological therapy. Out of that entire list, everything except your genes are modifiable factors.

Our approach to chiropractic is focused on the head and neck, which has been shown in at least one study to improve long term outcomes in patients with fibromyalgia syndrome when combined with exercise and cognitive based therapy. You can read more about that in a previous article below:

Fibromyalgia and the Atlas

Conclusion

At the end of the day, there is no cures for rheumatoid arthritis or fibromyalgia yet. There may not be cures for years to come. However, many people with these illnesses can see their quality of life improve by addressing some of the neurological consequences of the disease.

Dysautonomia – A possible cause of post-concussion syndrome

Dysautonomia and PCS

With concussion being a dominant topic in sports medicine, we have seen a large spike in research dollars being spent to study the effects of brain injury. Despite our increased knowledge, when someone has concussion symptoms for longer than 30 days, there still isn’t great consensus as to why these people develop persistent symptoms and what is causing it to happen.

The symptoms of post-concussion syndrome (PCS) are what make the illness difficult to understand. The primary symptoms of PCS include:

  • Persistent headache
  • Dizziness
  • Loss of balance
  • Difficulty with concentration/brain fog
  • Nausea
  • Impaired or slow cognitive activity

The symptoms are vague and non-specific. In medicine, there’s a tendency and a desire to have a condition be linked to one very specific piece of anatomy. That way you can treat the diseased organ and cure the illness.

The reality is that a head injury is likely disrupting multiple body parts simultaneously. The higher centers of the brain aren’t the only things that get scrambled during a concussion. A concussion is likely damaging multiple areas in the brain along with the inner ear organs, the neck, the jaw, and the eyes.

Since every head injury is unique in terms of velocity, direction, and magnitude, it means that each person’s head injury is likely to impact their anatomy in individual ways. This is where you can have a lot of variation in how someone with post-concussion syndrome looks symptomatically.

Another struggle is that different body parts can create similar symptoms. An injury to the neck can cause a feeling of vertigo just like an injury to an inner ear organ. An injury to the neck can also cause headaches symptoms just like the eyes or the vessels in the brain.

Some doctors are looking at another potential cause of persistent concussive symptoms called dysautonomia.

Dysautonomia – A Fight Between 2 Super Systems

Dysautonomia is a condition where the brain loses normal control of the internal organ systems of your body. Dysautonomia can show up in organs like the digestive system, bladder, glands, and pupils. Classically, these disorders show up in the cardiovascular system by affecting your heart rate and blood pressure.

Autonomic Nerveous System Chart

The autonomic nervous system is compromised in patients with dysautonomia

The most common disorders linked to dysautonomia are:

  • Multiple sclerosis
  • Fibromyalgia
  • Postural Orthostatic Tachycardia Syndrome (POTS) – an illness characterized by rapid heart beat to 150-200 bpm at rest
  • Neurocardiogenic syncope – a disorder characterized by unpredictable fainting attacks.

When people have these disorders then the broken function of the nervous system causes people to feel dizzy, in a fog, extremely fatigued, light headed, and anxious. When you read those symptoms on paper (or screen) it doesn’t sound like much, but the way those symptoms persist can drive someone mad.

People don’t just have a brain fog, they are scared and frustrated that their brain won’t allow them to focus and accomplish a task.

People don’t just have fatigue, they have an inability to socialize and be effective at work and at home because of exhaustion.

People don’t just have dizziness, they are worried about driving and being in open spaces because their body is betraying them.

People don’t just have a rapid heart beat, they have fear and anxiety that this next attack could put them in the emergency room.

Having dysautonomia whether it’s an illness on it’s own like POTS, or part of another illness like MS can make life much harder and depressing, because treatment for the illness is really limited.

Post-Concussion Syndrome and Dysautonomia

Going back to post-concussion syndrome, we discussed how the illness can be extremely frustrating because doctors and scientists have had a hard time coming to a consensus as to where the symptoms are coming from.

Some doctors and scientists are presenting an interesting theory that cases of post-concussion syndrome may be a manifestation of dysautonomia.

One of the first studies to look at this phenomenon was done in 2016 on young patients with persistent concussion symptoms. The study involved a test called the head-upright table tilt test. You can check out the full study here:

Orthostatic intolerance and autonomic dysfunction in youth with persistent postconcussive symptoms: a head-upright table tilt study

Image credit to Stickman Communications

Image credit to Stickman Communications

This test is used to diagnose feinting conditions but is also a hallmark test for POTS. The study showed that 24 out of 34 PCS patients had findings on the test indicating a form of dysautonomia. 10 Patients had syncope while 14 patients had POTS.

Even more interesting was that when the patients with POTS stopped having PCS symptoms, they also stopped having a reaction to the table tilt test when re-examined.

Another 2016 study showed that patients who have a history of concussion show a decreased ability to modulate their heart rate and blood pressure at rest indicating a loss of autonomic control. This was happening in patients without any overt signs or symptoms of dysautonomia.

Valsalva maneuver unveils central baroreflex dysfunction with altered blood pressure control in persons with a history of mild traumatic brain injury

Then you also have a wide range of studies looking at how concussion can impact your heart rate variability which is an increasingly utilized biomarker for autonomic nervous system activity.

HRV Studies

A dysautonomic theory of post-concussion syndrome can also help explain some of the unusual symptoms that may arise after a head injury. While it’s easy to understand how a PCS patient can have persistent headache and dizziness, there are a lot of people who will have a concussion or whiplash and start developing persistent gut issues and sensitivities to foods. Dysautonomia as a culprit helps to make better sense of this phenomenon.

What Does This Mean for Treatment?

Dysautonomia is a condition that is not well recognized by many physicians and there aren’t many choices for effective treatment options. In dysautonomia, the brain is having a terribly hard time making sense of its environment.

There’s some interesting work going on utilizing balance and vestibular exercises and graded cardiovascular exercise to help the brain recover from injury, but I’ll cover that on another day. Today I want to talk about the veins in your neck.

Dr. Michael Arata is an interventional radiology specialist in Southern California. I heard him speak at a conference in 2015 where he talked about the effect that the veins in your neck could have on your autonomic nervous system. It’s been an interesting and controversial theory that has been tied to illnesses like multiple sclerosis where dysautonomia is a hallmark of the illness. When the large veins in the neck become narrowed or occluded, it can cause abnormal fluid movement in the brain leading to venous reflux, congestion, and neuroinflammation in the brain.

Dr. Arata even published 2 studies that demonstrating that a procedure that uses a balloon to open these veins was able to create changes in the autonomic function of patients with multiple sclerosis including heart rate variability and blood pressure control.

Transvascular autonomic modulation: a modified balloon angioplasty technique for the treatment of autonomic dysfunction in multiple sclerosis patients.

Blood pressure normalization post-jugular venous balloon angioplasty

But that wasn’t the most interesting part of his presentation. During his talk, he talked about the concept of the atlas vertebra creating compression on these vascular structures. He even used an imaging technique called a venogram to show this happening in his patients:

Dr. Arata shows images of a venagram to show how atlas rotation can disrupt the internal jugular vein

Dr. Arata shows images of a venagram to show how atlas rotation can disrupt the internal jugular vein

It’s because of this phenomenon that Dr. Arata actually refers some of his patients for upper cervical correction so that they can influence this part of the autonomic nervous system.

If dysautonomia is a primary symptom generator in PCS patients, then the impact from a potential neurovascular insult like an craniocervical displacement should be considered especially considering the mechanism of injury includes a blunt force to the head.

An Personalized Approach to Post-Concussion Syndrome

Patients with post-concussion syndrome with signs of dysautonomia likely have multiple systems that must be addressed to regain normal functionality. In addition to dysfunction in multiple systems is the idea that each person will have a varying tolerance to different therapies.

In truth, no single therapy is likely to fix someone with persistent post-concussive symptoms and dysautonomia. These patients need to improve their tolerance to exercise with gradual increased load (especially if they’re an athlete). They also need vestibular rehabilitation so that their brain can move the head and eyes normally again. There’s no disputing the necessity and usefulness of those treatment strategies.

However, if we are concerned about the chronic effects of head injury and the ability to improve fluid movement through the brain, then we have to consider the impact that trauma has on the structural alignment of the neck and the neuroinflammatory consequences that these injuries can leave behind.

Combating Medication Overuse Headaches

Medication Overuse Headaches

Medication overuse headache (MOH) is a very common manifestation of chronic headache patients. It is one of the unique instances where a once effective way of controlling an illness will actually perpetuate the illness further as the body adapts to a chemical intervention. This condition is unique to patients with chronic daily headache disorders and various chronic pain syndromes like fibromyalgia.

The most frustrating part about MOH is that you may do better for a long period of time because of a medication, but as the effectiveness of the medication wanes over time you may actually experience the headache worse than before.

It’s a situation that can cause despair as medications are generally the treatment of choice for all headache conditions. If your body has become resistant to all of the available medications, what can you do next?

Why Is Your Medicine Making Your Head Hurt?

People with chronic headaches will generally have 7-10  headache days per month. For better or for worse, there are a wide variety of medications that can help knock a headache out or prevent them from occurring. It’s not unusual for a chronic headache patient to have  a cocktail of drugs that they have to take on a daily basis.

The problem with a frequent medication regiment in chronic pain conditions is that the cells of your body almost always have an adaptation to to make itself more resistant to the medications’ effects. This can happen even if you’re taking your medications correctly as prescribed by your doctor.

The headache that results from MOH is often called a rebound headache. As the effect of the medication wears off, the headache returns rapidly which can create a need for another dose of medication. In this way it becomes a cycle of struggle as the effects of the medication start to decline faster and the rebound headaches become more persistent. When this occurs, the chronic headache patient can become the chronic daily headache as the headaches will begin to occur greater than 15 days per month. Because of the reliance on these medications, medication overuse headache has become the 3rd most common headache disorder, and the most common cause of migraine-like symptoms.

Research has shown that this can occur regardless of the type of medication you take. It’smost frequently associated with prescription migraine medications, but it has been documented to occur in people taking over-the-counter drugs like ibuprofen. Hard pain meds like oxycontin may be used by headache patients without a doctor’s prescription, and these can tend to accelerate the process to MOH because of the way that opiods sensitize your brain.

You can read more about how pain pills can make your pain worse in this article I wrote last year:

Research: Can Pain Pills Cause More Pain Over Time?

How to Beat Medication Overuse Headaches

The easy answer is to stop taking your medications for a while because….

you can't if you dont

If you don’t understand this meme, then ask someone who is younger than 30. I promise it’s funny.

Unfortunately, biology isn’t that simple, especially if you have chronic pain.  Are there side effects to stopping a daily medication? Will you experience worse pain when you stop taking the drugs? How will you cope with the pain if you can’t take any meds? How long will this take before you can make the meds work again?

Chronic headache patients need effective non-pharmacological methods to deal with the pain of headache physiology.

One specific target for drug-less treatment of headaches is by correcting dysfunctions in the neck.

In many cases, headaches syndromes can be a result of a secondary effect of a shift in at the top of the neck. This is why chronic headache patients are some of my favorite people to see in practice because a gentle correction of the neck  has allowed us to have a very high success rate with chronic headache syndromes.

While addressing the cervical spine may not address the cause of  a medication overuse headache, it may help fix the primary source of a patient’s headache condition so that taking the medication becomes less necessary. The most common comment I get from headache patients is when they tell me that they’re taking less ibuprofen since they started getting their neck better.

A shift in the atlas can disrupt fluid in the spine and cause neuroinflammation in the brain. In some cases, this may be tied to MS.

A shift in the atlas can disrupt fluid in the spine and cause neuroinflammation in the brain. In some cases, this may be tied to MS.

Within 2 weeks of neck corrections with the NUCCA procedure, the vast majority of our headache patients experience relief in either the frequency or intensity of their daily headaches.

Not All Neck Adjustments Involve Cracking

A lot of people are scared about having their neck worked on by a chiropractor. The general portrayal of a neck adjustment by viral Youtube videos can make it seem scary.

While chiropractic adjustments have a tremendous track record for safety, the bottom line is that a lot of people just don’t want their neck cracked because the sound and the motion make them really uneasy. This leads to patients tightening up their neck and bracing which can make a neck manipulation hurt in the hands of a chiropractor that is not skilled.

That’s one of the big reasons why I’ve used the NUCCA procedure throughout my career. The NUCCA procedure involves a very light pressure to correct the neck as opposed to a high velocity manipulation. By using the NUCCA procedure, the doctor is able to measure and control how much force goes into the neck, and if we have corrected the underlying dysfunction. All of this happens without the popping, twisting, or cracking of the spine.

Not all patients with headaches are good candidates for the NUCCA procedure. Only patients with a subtle shift in the top vertebra called the Atlas will benefit from the NUCCA correction. A thorough history and examination will help us determine if the Atlas is causing a problem and if it’s something that can be fixed.

The Anatomy of a Headache

The Anatomy of a Pinched Nerve

Let’s talk about vertigo. Technically a diagnosis of vertigo should be confined to a sensation of spinning or rotation in the absence of movement. However, for purposes of this conversation we will discuss the wide range of vestibular disorders that are often described as dizziness or vertigo.

When people say they are feeling dizzy it usually means that they have a feeling of being in motion without actually being in motion. It could be the feeling of swaying like a boat, feeling drunk or woozy, feeling a sense of fogginess, or even just really light headed.

It’s not unusual for people to feel these sensations periodically after having too much to drink or after a wild ride on a roller coaster. However, if you have these sensations chronically without a precipitating event, then you likely have chronic vestibular dysfunction.

Chronic vestibular dysfunction is challenging to diagnose and treat. It can be a secondary effect of a different diseases like multiple sclerosis or it can be a primary vestibular disorder like positional vertigo. Either way, these conditions can be related to the following pieces of anatomy:

 

The Semicircular Canals

When it comes to a true sense of vertigo where you or the world appear to be spinning, then the most likely culprit are these tiny little tubes in your inner ear called the semicircular canals.

The semicircular canals are inner ear organs that tell us what direction our head is moving

The semicircular canals are inner ear organs that tell us what direction our head is rotating.

These tiny little tubes in your ears are roughly oriented into in the main directions of movement of your head. When you bend your head forward or backward, turn, or bend to the side these little tubes give powerful signals to the brain to let you know where your head is moving in space.

These canals are lined with tiny hair cells called cilia which are your receptors for balance. The canals are also filled with a fluid called endolymph. When your head moves, this fluid moves inside the canals and stimulates these hair cells.

These organs are almost hard wired to movement of your eyes, so that when you move your head in one direction, your eyes reflexively move the opposite way.

What Can Go Wrong?

The most common problem to affect these canals is called benign paroxysmal positional vertigo (BPPV). In this condition, little tiny crystals in the otolith get dislodged and jump around in the semicircular canals. These crystals will move the hair cells in the canal causing them to fire without the appropriate head movement.

When that happens, your inner ear is firing like your head is moving in one direction when it is not actually moving. This causes a sensory mismatch in which the canals almost always win. Therefore your ears tell your brain your head is moving, and your eyes will start moving inappropriately to match it, and now the world is perceived as spinning.

The Otolithic Organs

The otoliths are a pair of small swellings in the inner ear called the utricle and the saccule. Like the semicircular canals, they are lined with small hair cells that become stimulated by the movement of fluid and crystals as the head moves. For ease of understanding, the utricle is a more horizontal structure and detects side to side motion of the head, while the saccule is more vertically oriented and detects up-down movements.

These play a huge role in the brain’s perception of gravity. As a chiropractor, this plays a huge role in what we do. One of the first signs of a problem in these little organs is the presence of head tilt. Over time, this head tilt can start causing neck pain and headache.

The otoliths monitor straight motion of the head and neck

The otoliths monitor straight motion of the head and neck

What Can Go Wrong?

The otolithic organs are not understood as well as the semicircular canals. The crystals that cause BPPV are dislodged from the utricle and they may play a role in otolithic disorders.

When the otoliths are involved, you are less likely to feel the “spinning” type of vertigo, but more likely to have a sense of tipping over, walking off balance, or feeling like you’re rocking on a boat. The otoliths are also likely to be implicated in motion sickness.

This can also lead to abnormal head tilts, blurry vision, neck pain, and headaches. You can read more about that here:

Is Head Tilt Driving Your Brain Crazy

The otoliths are susceptible to toxicity from certain medications and various enviornmental toxins. When substances affect the inner ear, it can cause ringing in the ears and balance disorders. Substances like certain antibiotics, heart medications, aspirin, diuretics, chemotherapy compounds, and more. One of the most common compounds I see that is ototoxic includes neurontin. A common drug used to treat chronic pain and neurological disorders.

The otoliths can also be prone to traumatic head injury, but we’ll get more into that shortly.

The Vestibulocochlear nerve

The vestibulocochlear nerve is a specialized nerve called a cranial nerve. This nerve travels from your inner ear to the brain stem. This nerve is linked to specialized receptors that transmits sound and balance information from the inner ear so that your brain can process it.

Whenever you your otoliths or semicircular canals sense movement, the hair cells of the inner ear fire and travel down the nerve towards the brainstem for processing.

The vestibular cochlear nerve carries hearing and balance signals from the ear to the brain.

The vestibular cochlear nerve carries hearing and balance signals from the ear to the brain.

 What Can Go Wrong?

Because this nerve transmits both sound and balance information, damage to this nerve can compromise both your sense of hearing and balance.

This nerve is susceptible to inner ear infections, tumors, and neurodegeneration. Illnesses that cause labyrinthitis or acoustic neuritis can make you feel dizzy and off balance through the inflammatory response.

The Brainstem

The brain stem is the most primitive part of the brain responsible for most life sustaining processes in the body. It is also home to the cells that form the specialized cranial nerves like the vestibulocochlear nerve we just discussed.

The Brainstem is the most primitive part of the brain, but governs most of the life sustaining processes for the body.

The Brainstem is the most primitive part of the brain, but governs most of the life sustaining processes for the body.

The brain stem also acts like a central processor of a computer. It takes a lot of the inbound information from the body and filters it down into a signal that the brain will how to use it. This is especially important for your balance system.

A specific area of the brainstem called the vestibular nuclei are responsible for coordinating the signals coming from your eyes and ears. When your head moves, the inner ear sends signals to these brainstem cells which will help move the eyes. This way your head movement and eye movements are purposeful and coordinated.

What can go wrong?

The brainstem can be injured by strokes and traumatic injury. Dizziness is one of the primary symptoms of stroke and concussion because of the way they hit the brainstem. That means your inner ear can be healthy or in tact and your world is spinning and off balance because the part of the brain that is supposed to make sense of all of this is injured.

These patients often struggle worse with their balance symptoms because they don’t play by the same rules as the previous types. The balance issues may be unrelenting or unpredictable because the central control system is compromised. A central cause of vertigo is likely the culprit in cases of migraine associated vertigo.

These cases of vertigo are of central origin and usually require treatment or therapies that are a lot different from those that affect the semicircular canals, otoliths, or vestibular nerves.

The Neck

The neck is a really common but under appreciated cause of vertigo. Because the neck holds our head up, it provides a lot of feedback to the brain about where the head is in space. The contraction of your neck muscles tell your brain if your head is pointing up, down, left, or right. Additionally, your spine is loaded with millions of tiny little sense organs or cells called mechanoreceptors.

These receptors fire in response to the way that muscles and joints are loaded. When they fire, it helps the brain decide on the quality and accuracy of movement

The neck is a common but underappreciated source of vertigo

The neck is a common but underappreciated source of vertigo

What can go wrong?

Injuries, misalignment, or degeneration of the the spine can alter the way these mechanoreceptors fire. If your brain is getting poor or inaccurate feedback from the neck, then it causes a sensory mismatch with the eyes and inner ears. This sensory mismatch is at the core of vertigo and balance disorders.

Many of these cases respond favorably to chiropractic adjustments or other types of manual therapy. In fact, a diagnosis of cervicogenic vertigo is usually based off the fact that vertigo resolved because of a treatment to the neck.

It’s a challenging condition to diagnose because it’s a rare condition where the treatment often dictates the diagnosis.

Don’t Leave Your Doctor’s Office with a diagnosis of vertigo

A lot of people leave a doctor’s office with dizziness and come back with a diagnosis of vertigo. This is an utterly useless diagnosis. They’ve basically taken the fact that you said you have dizziness, and gave it a latin name. You can read more about that here:

Vertigo is NOT a Diagnosis

You have to figure out what anatomy is causing your condition. While vertigo looks and feels similar no matter what anatomy is causing it, the way that it needs to be treated can vary greatly.

Vertigo and balance disorders are tough conditions to treat medically because drugs do a poor job selectively targeting these very different pieces of anatomy. Many of these cases have a mechanical and neurological cause, and can be rehabilitated using mechanical and neurological strategies.

If you see a doctor who is not caught up on current strategies to rehabilitate balance disorders, then you might be leaving a doctor’s office thinking that your balance problem is untreatable.

The first step to addressing vertigo is to identify the anatomical cause, and then getting you to the right professional who is equipped to manage this debilitating condition.

Is Cardio Useless? Your Brain Says No

Is Cardio Useless

 

As of the timing of this post, I consider myself primarily a weightlifter when it comes to fitness. If you follow my social media posts on Instagram, Twitter, and Facebook you’ll mainly see photos and videos of squats, snatches, cleans, and other movements that involve heavy barbells.

A popular trend in fitness is to condemn forms of exercise called steady-state cardio, which is your classic endurance exercise like long distance running, rowing, cycling, etc. Critics will say steady-state cardio is ineffective for putting on muscle mass and strength as well as a negligible effect on weight loss so it should be discarded as a form of exercise.

Whenever gym bros start talking about cardio

Whenever gym bros start talking about cardio

All of those things are pretty accurate. Cardiovascular exercise has a marginal effect on strength and hypertrophy, and in the absence of diet no form of exercise really promotes weight loss. But this doesn’t mean that cardiovascular exercise is useless. The effect that cardiovascular exercise has on your brain can be life changing.

Cardio and Neurogenesis

Neurogenesis is a term that scientists use to describe the growth of new neurons. For decades it was a widely held belief that all of the brain cells you are born with are the ones that you will have forever. In more recent years, scientists have identified parts of the brain that do produce new brain cells on a regular basis……just a lot more slowly than something like your skin.

One particular region in the brain that is well known to undergo neurogenesis is called the hippocampus.

This little chunk of brain is one of the few areas that can produce new neurons regularly.

This little chunk of brain is one of the few areas that can produce new neurons regularly.

 

The hippocampus is a piece of our brain that is associated with the formation of memories and in learning. It’s been well established in rat studies that neurogenesis happens in this part of the brain, and exercise enhances this process. [Source] But that’s just a rat study. Does this actually happen in humans?

While we can’t put humans on a treadmill for 30 minutes and cut out their hippocampus, there are studies that imply that neurogenesis happens in humans after cardiovascular exercise too [Source]. These studies have showed that exercise improves memory scores, increases the size of the hippocampus, and produces higher amounts of brain derived neurotrophic factor which is the chemical compound associated with neurogenesis.

That’s pretty amazing stuff! This is the type of stuff that helps to explain why people that exercise regularly have a lower risk of dementia. It also helps us understand how exercise can help combat things like ADHD and other brain related disorders.

Does Weight Training Have the Same Impact?

Scientists who did the study on rat brains found that aerobic exercise had double the amount of neurogenesis as sedentary rats. They also found that rats who did resistance exercise had very little effect on the rat brains, even though the rats got physically stronger. Source

Now we have to take that with a grain of salt because:

  1. Rats aren’t people.
  2. The way that the scientists “strength trained” the rats is by tying a weight on their tails and making them climb with it. Not a terribly good comparison to men and women who voluntarily lift weights recreationally.

The biggest take away from this study is the way that aerobic exercise seems to pump up that brain derived neurotrophic factor which may be a key to making your brain grow and heal.

While the effects of weightlifting on neurogenesis hasn’t been studied yet, there is compelling evidence that suggests weight training is beneficial in people with early stages of memory loss. Resistance training has been shown to improve general cognitive performance ¹, improve blood flow to memory areas of the brain ², and save seniors with memory problems money ³.

All Exercise Is Beneficial

At the end of the day, all kinds of exercise is beneficial for different reasons. We have developed a stronger understanding for how cardio can benefit the brain, and there is data that shows that weight training also gives the brain a boost.

There’s no need to shame someone’s exercise of choice. There are so many people that don’t move at all, that anything that a person can do to be active and move regularly will provide them a substantial benefit.

Now if you’re a fitness junkie already, then taking a balanced approach and incorporating something you usually avoid is a great recipe to get the maximum benefits of exercise.

If you are someone that lifts weights 4 days a week without fail, then maybe taking a 2 mile run or row would be a great addition to your weekly regiment. If you run daily and never do strength, then you should definitely look into resistance training to supplement your cardiovascular fitness.

Your brain thrives on exposure to new things.  Beyond some nice looking muscles and better heart health,, the biggest benefit of exercise is making your brain better.

Why Concussions Hit Migraine Patients Harder

Migraines and Concussions

 

The vast majority of people who suffer concussive injuries will recover without any chronic symptoms. However, about 15% of people who suffer concussions will go on to have post-concussion syndrome, where they will experience headaches, dizziness, and cognitive problems beyond 30 days after an injury. These symptoms can be debilitating, and some people can experience the effects of these head injuries for years later.

A lot of research has been done to identify people who are at higher risk of developing post-concussion syndrome. The most significant risk factor for this is having multiple concussions, but that’s a rather obvious one. The more concussions you’re exposed to, the greater the opportunity to have chronic symptoms. However, research has pointed to one specific risk factor that seems to contribute heavily to post-concussion syndrome in the athletic population. That risk factor? A history of migraine headaches.

Migraines and Concussion: a terrible duet

Post-traumatic headache is one of the hallmark symptoms of post-concussion syndrome. These headaches look a lot like migraines because of the wide range of neurological symptoms that concussions can cause.

It’s no secret that concussions can cause terrible headaches in people, but many people don’t know that having a history of migraine headache is a risk factor for worse outcomes in post-concussion syndrome. ¹ ² ³

This is important for a couple of reasons:

  1. If you know someone with migraines is at a higher risk for post-concussion symptoms we can be better prepared to see appropriate specialists in the event of a concussion.
  2. We have a better understanding for why sports like girls’ soccer are more susceptible to concussive injuries and can be more prone to chronic post-concussion syndrome.
  3. Because understanding the common physiology in migraines and concussion can help us identify effective treatments for one of its most debilitating symptoms.

Migraines, Post-Concussion Syndrome, and the Neck

Treatment for headache symptoms in migraine and post-concussion syndrome are pretty similar. Amitriptyline, propanolol, and topirimate. These medications target receptors in the brain that can become overactive and underactive during a migraine attack.

Most research is focused on finding effective drugs to treat headaches, but this treatment philosophy ignores the fact that the headaches from a migraine or concussion can often stem from dysfunction of the cervical spine.

When the neck is compromised the muscles and nerves that surround the upper neck can become areas of concern for the headache patient. The muscles at the top of the neck transmit information to the brain about where the head is in space.  Studies have shown that these muscles can be tied to chronic headache symptoms. ¹ Some studies have even shown that cutting these muscles can lead to headache relief.¹

You can read more about these troublesome little muscles on a previous article I wrote here:

Is This Small Neck Muscle Driving You Mad?

 

The muscles in the deep part of the neck have been implicated in headache disorderrs

The muscles in the deep part of the neck have been implicated in headache disorderrs

 

Additionally, the nerves in the top of the neck are important transmitters of pain. The C1, C2, and C3 nerve roots in the neck are linked to the trigeminal cervical nucleus which is an important relay center for pain in the head. Branches off the C1 nerve like the suboccipital nerve have been targets for nerve blocks in migraine patients with good success.¹

 

The nerves in the upper neck play a major role in headache physiology

The nerves in the upper neck play a major role in headache physiology

 

These mechanisms are important because research has shown that whiplash and concussions can have a significant impact on these anatomical structures. ¹ ² ³

Concussions Worsen Cervical Spine Problems

So here’s the main issue. Many (but not all) migraine issues can be tied to the neck. More than 80% of the migraine patients that come into our office get a tremendous improvement in the frequency of their migraine attacks just by fixing biomechanical issues in the neck, and there is some research that supports it. ¹

When someone has a biomechanical issue in their neck, then a major blow to the head like a concussion can make these neck problems worse. Several studies are starting to show that there are some interesting similarities with what happens in a whiplash and what happens in a concussion. The fact is that the amount of force that it takes to cause a concussion FAR exceeds the amount of force it takes to create a mild whiplash injury.

Whiplash and Concussion

The force required to sustain a concussion far exceeds the forces necessary to cause a whiplash

Obviously not every force over 5 g’s causes a whiplash and not every force over 100 g’s causes a concussion. Otherwise we’d all be walking around with with severe neck injuries every time we got off a roller coaster. There are factors involved like neck strength, timing of muscle bracing, and previous injuries that affect our susceptibility to these forces.

My point is that if you have sustained a concussion, then the probability of you also suffering an injury to the neck is really really high.

If you were a migraine patient before the concussion and the migraine was stemming from your neck, then the odds of that neck injury becoming worse and making the healing process after a concussion is much higher for you than most others.

If you had a small biomechanical issue in your neck that was contributing to your migraine headache symptoms, then the force of a concussion is going to injure the ligaments and muscles that were already compromised! This is addition to the way that concussions knock out your vestibular and ocular systems which are also known contributors to headache physiology.

Addressing the Neck

So what does this mean for you?

  1. If you are an athlete and have a migraine headache problem, you should get your neck checked and rule out any biomechanical problems in the upper cervical spine. Fixing these issues will likely address your migraines, and may provide some protection from head contact.This is even more true for female athletes than male athletes. Women suffer from migraine headache issues at a much higher rate than men, and this can be a contributing factor to the increased rates of concussion we see in girls’ soccer.
  2. If you play contact sports, getting your neck stronger may provide protection from concussive injury. Again, this applies even more so to female athletes because women will tend to have smaller neck muscles than men. Weight training and specific neck exercises is a safe and easy way to possibly mitigate this risk.
  3. If you have a history of neck injury from whiplash and concussion, make sure you’re seeing someone with expertise in addressing the cervical spine. People with traumatic neck injuries may not respond well with vigorous treatment methods and may regress with too much force applied to injured tissue.

Is Head Tilt Driving Your Brain Crazy?

Is Head Tilt Driving Your Brain Crazy?

 

A lot of people are starting to recognize the role that posture plays in overall health. Things like text-neck has made it’s way to major publications like the Washington Post, and the perils of slouching have been written about ad nauseum.

I won’t get into that today, because I think there’s a problem that is a lot more important but gets far less attention. Most doctors will ignore this, but chances are it’s a major contributor to headache, balance disorders, vision problems, and overall brain health.

Today we’re going to break down your head tilt.

Cute for Puppies and Sorority Poses, Bad for Patients with Neurological Issues

First we should clarify a couple of things. When we discuss head tilt, we’re not talking about the tilt that comes on when you intentionally tilt your head for a photo. If you are intentionally creating a momentary head tilt, it’s not a big deal. There’s no such thing as a bad posture if you are willfully and intentionally trying to create a specific shape with your body in gravity.

We only classify postures as negative when your body is doing something that it is not intending. If I ask you to stand up as straight as you can and your head tilts to side, it paints a much different picture of your brain than if I asked you to purposefully hold your head to the side. An inability for you to create a straight upright posture suggests that you have a deficiency in your brain’s ability to control your muscular system. You can read about that in greater detail here:

Why Your Posture Isn’t That Important

So what’s the big deal if your head tilts to the side?

It’s a sign that your brain is perceiving the world around it incorrectly.

If your brain is getting wrong information from your senses, then it can’t produce the right response to the world around it.

It doesn’t sound like a big deal when we’re talking about posture, muscles, and bones, but let’s apply the same idea to some of your other senses:

  • If you have a problem with one of your eyes, how will that affect your ability to catch a baseball?
  • If your ears are hearing a high pitched noise all of the time when everything is quiet, how will that make you feel?
  • If your skin is constantly itching, but you have nothing on your skin that is irritating it, will you keep scratching?

All of these are examples of your brain perceiving the environment incorrectly and they all lead to specific conditions from a lack of depth perception, tinnitus, to neuropathic itch. When left for a long time, these conditions can have a significant impact on your enjoyment of life.

So what are the consequences of a chronic head tilt?

The Physiology of Head Tilt

How your brain decides to hold the head up involves a lot more neurology than most people expect. Generally speaking, we think about head tilts being a result of tight muscles pulling the head out of place. When we use this model, treatments become a matter of rubbing one muscle and stretch another and the head will be straight again.

For better or worse, the way the brain moves the head is WAY more complex than that. Your brain decides where to put your head in space based on the interplay of your inner ear organ, your eyes, and the small muscles of your neck.  Here’s how it works:

Normal Head Tilt Reaction

So this is what happens when the system is working okay. When the system works, you can tilt your head when you choose to, but your brain will bring your head back to the normal upright position after it has achieved its purpose.

We see this system break frequently when someone has injuries like whiplash or concussion. The impact of these injuries disrupts normal function of all three systems. It scrambles the inner ear which distorts your eye movements. It also wreaks havoc on the muscles and ligaments of your neck.

What Happens When Your Head Tilt Breaks?

This is why the biggest problems associated with whiplash and concussion injuries are balance and vision issues. You can’t keep your perception of the world straight if your eyes, ears, and spine are giving you inaccurate information about gravity!

When your head and neck get scrambled by a hit and you disrupt these 3 systems, your body takes on an abnormal head posture which can make the other systems work inappropriately. One of the first things I’ll ask someone during a consultation is to sit up as straight as they can, and I’ll look at where they put their head in space. Very often they look like this:


Abnormal Tilt Reaction

 

 

But let’s be honest here; you don’t really care if you have a head tilt, crooked eyes, and tight muscles if it’s not causing you any pain or discomfort right?

Here’s the thing, your body can compensate like this for a little while. But if you’ve ever had to rely on a back up system before, you probably know that backup systems aren’t ideal and they’re more prone to glitches and failure. Your body is the same way with its own back up systems. They will get you out of a pinch for a short time, but they will eventually fail. Or even worse, you may suffer another injury while you are compensating and have even more damage to the brain.

So as your back up systems start to fail and your eyes and neck aren’t working normally you will start to have problems like:

  • Dizziness
  • Feeling off balance
  • Neck and back pain
  • Headache
  • Nausea

Why? Because if your eyes don’t move well, then it leads to difficulty reading or tracking targets in space. If your neck doesn’t move well, it causes pain and headaches. If you have all three systems saying different things, your brain has no idea how to determine it’s sense of balance.

Your Brain Hates Mismatches

Your brain hates it when its sensory organs give it conflicting information causing sensory mismatches. It hates it more than your significant other hates it when you walk out of the door with a brown belt and black shoes.

Your brain hates sensory mismatches even more than your significant other hates this fashion faux pas

All kidding aside, these sensory mismatches are the main trigger for the balance issues that can make people miserable. When you combine that with the fact that the balance system shares connections to your autonomic nervous system, then it gives us an understanding for why balance problems can really wreak havoc on our stress response system.

The abnormal movement of the eyes and head are also likely to create persistent headaches and pain in your joints and muscles from abnormal loading patterns.

When your head tilts, all of your spinal system starts to act screwy

When your head tilts, all of your spinal system starts to act screwy

While the symptoms can be bad enough, the biggest concern is the impact that these maladaptive patterns have on the functioning of the brain as a whole. If you can’t orient your world properly, then the parts of your brain that are responsible for normal function start to degrade while the parts of the brain that are producing these abnormal patterns get stronger. This persistent abnormal head pattern can change the way blood flow and oxygen get to various parts of the brain and lead to further problems with thought, focus, and movement.

If we want to make a real impact on the health of your brain, then we have to allow the brain to stop compensating and get your head on straight again.
