Vestibular migraine and spontaneous vertigo – Migraine Associated Vertigo
Ross Hauser, MD
This article continues and provides further discussion and information on cervical vertigo. Please refer to Cervical Vertigo and Cervicogenic Dizziness from more discussion, patient cases, and treatment options for problems of dizziness.
When people come into our offices with a problem of Vestibular migraine, spontaneous vertigo, or Migraine Associated Vertigo they talk to us about a very long medical journey they have taken that no one can quite understand. This includes family and the medical professionals that these people have seen already looking for help and support. If their stories are similar to your story, you will know that these people spend a lot of time looking for the triggers that cause the “silent migraine” a headache-free migraine, and the sudden, spontaneous vertigo that comes with it.
Here are some of the things we have heard from our patients:
My doctor sent me to a nutritionist. We did allergy food testing, which I was sensitive to a few things. I was told no sugars and no caffeine because in addition to the dizziness I would suffer from sudden onset panic attacks and of course, this whole problem with my health leaves me pretty much exhausted with stress and anxiety.
I am still on the diet, I think it has helped somewhat, but I still get these symptoms of migraine aura and then dizziness. They even come to me in my dreams.
I have been on Verapamil, it helps a little. My doctor thinks it would work better if I had symptoms of Meniere’s Disease. I do have a sway to me.
Treatments for me up until this point have not been successful. Things do not work for me long-term. At this point, I would be grateful if something worked for me short term. As my symptoms got worse I would get more diagnoses and more medications. I started to get confused as to whether my worsening symptoms were the result of side effects from these medications or new manifestations.
I thank god that I am still somewhat functional and that I have a supportive husband. I am also grateful that these attacks seem to have been less dramatic and less frequent, however, they are still there in the back of my mind. I wish I had answers.
If this story sounds familiar to you and you are also searching for answers, this article will present one possible answer for you. That your symptoms are being caused by cervical neck instability and physical problems in your cervical spine manifesting themselves in vestibular migraine and spontaneous dizziness. Let’s look at supportive research.
“No objective tests, imaging or audiologic, have been shown to reliably diagnose this condition”
This is the introduction to a paper from doctors at the Department of Otolaryngology, George Washington University Medical Faculty Associates. It was published in July 2021 in the journal Otolaryngologic clinics of North America. (1) If you feel that your doctor does not understand your condition, it may be because your doctor does not understand your diagnosis and why he or she is prescribing medications that may (hopefully) or may not work.
“Vestibular migraine is one of the most common neurologic causes of vertigo. Symptoms and International Classification of Headache Disorders criteria (see below) are used to diagnose Vestibular migraine because no objective tests, imaging, or audiologic, have been shown to reliably diagnose this condition. Central auditory, peripheral, and central vestibular pathway involvement has been associated with Vestibular migraine. Although the interaction between migraine and other vestibular disorders can be a challenging scenario for diagnosis and treatment, there are data to show that vestibular rehabilitation and a variety of pharmacologic agents improve reported symptoms and vertigo frequency.”
We will discuss pharmacologic treatment further below. Although if you are reading this article, you may yourself have reached a point where pharmacologic agents are no longer providing relief.
Explanatory note: The International Classification of Headache Disorders criteria calls for possible diagnosis of vestibular migraine when some of the following are present.
- Migraine and probable migraine, Migraine and probable migraine without aura, Migraine and probable migraine with aura, Migraine and probable migraine with typical aura. Migraine aura-triggered seizure
- Typical aura with headache, Typical aura without headache
- Migraine with brainstem aura
- Hemiplegic migraine (one side pain and especially weakness)
- Familial (hereditary) hemiplegic migraine (FHM – FHM Types 1,2,3)
- Sporadic hemiplegic migraine (SHM)
- Retinal migraine
- Status migrainosus (A migraine lasting more than 72 hours)
- Persistent aura without infarction
- Migrainous infarction
- Possible connections to gastrointestinal problems, Cyclical vomiting syndrome
- Possible connections to Abdominal migraine, Benign paroxysmal vertigo, Benign paroxysmal torticollis.
“Vestibular migraine is the most common cause of spontaneous vertigo but remains poorly understood.”
Poorly understood is a recurrent theme when it comes to patients with Vestibular migraine and spontaneous vertigo.
Stat Pearls is a publication of the National Center for Biotechnology Information, U.S. National Library of Medicine. In the article Migraine-Associated Vertigo (Vestibular Migraine) (2), Daniel B. Hilton and Carl Shermetaro of McLaren Oakland Hospital write of the complication surrounding the understanding of Vestibular migraine and spontaneous vertigo. (Article Updated July 2021) Again, this may explain why your health care providers are looking for answers for you.
- “Patients explain a sensation of motion when no motion is taking place or an altered sensation with a normal motion to define vertigo. In a vestibular migraine, the sensation is often described as a “to-and-fro” (backward and forward) sensation, and this can complicate diagnosis. Simultaneous headaches do not always accompany the vestibular symptoms, thus making an in-depth history and multi-specialty evaluation pivotal in order to make a diagnosis.”
- “Current management of a vestibular migraine consists of conventional migraine management as there is currently no accepted specific treatment for this disease. Additionally, convincing a patient of the diagnosis can prove difficult and lead to a delay in treatment or absence of treatment. This is understandable based on the fact that vertiginous symptoms are often asynchronous (happening at the same time) with a headache and maybe a difficult connection for the practitioner or patient to grasp.”
The difference between Vestibular migraines and migraines – Can your doctor tell? Maybe if you are post-menopausal, depressed, motion sick, complaining of imbalance, and of food-triggered headaches.
A June 2021 paper in the Journal of Neurology (3) comes from the Department of Neuroscience, Institute of Health Sciences, Dokuz Eylül University in Turkey. Here are the summary points:
- Vestibular migraine is one of the most common causes of vertigo in clinical practice but it is not always easy to make the correct diagnosis.
- The researchers found that Vestibular migraine patients were more likely than migraine patients to be female, post-menopausal, depressed, motion sick, complaining of imbalance, and of food-triggered headaches. In contrast, migraine patients were more likely than Vestibular migraine patients to have severe headaches, and that these can be triggered by certain odors and by noise.
The vestibulo-ocular reflex (VOR)
Another study published in October 2019, led by researchers at Massachusetts Eye and Ear Infirmary, Harvard Medical School, and Ohio State University also examined Vestibular migraine as one of the most common causes of spontaneous vertigo and why this problem remains poorly understood. The study was published in Scientific Reports (4).
Here are the learning points:
- “Vestibular migraine is the most common cause of spontaneous vertigo but remains poorly understood.”
- The researchers investigated the hypothesis that central vestibular pathways (dysfunctions of the body’s system to maintain balance) are sensitized (heightened) in Vestibular migraines by the vestibulo-ocular reflex (VOR) and vestibular and headache symptom severity.
We are going to move away from this research for some brief understanding notes and then we will return:
- The vestibular system is the body’s sensory system that regulates balance and spatial orientation (the understanding of where you are in your environment).
- It sits in the inner ear and works by adjusting fluid levels that act as the balance mechanism.
- As human beings, we set our awareness of our place in space by using the ground as the constant place of orientation. We can keep our balance when we walk because we understand the ground is the constant and our vestibular system makes constant involuntary adjustments to “keep things steady,” to prevent motion from creating dizziness or sway.
- It sits in the inner ear and works by adjusting fluid levels that act as the balance mechanism.
Why vestibulo-ocular reflex may connect other symptoms to Vestibular migraine
A May 2021 paper in the journal Otology & Neurotology (5) found a significantly higher prevalence of enhanced vestibulo-ocular reflex responses in patients with Menière’s disease, central origin vertigo, otosclerosis (abnormal bone growth in the ear), and vestibular migraine than in those with other neurotologic diseases and controls. This study found that enhanced vestibulo-ocular reflexes are not pathognomonic (indicative) of hydrops-related diseases and the diagnosis should not solely be based on these and instead take into context other clinical and examination findings. In other words, look at the other symptoms and conditions.

Returning to the study
- Vestibular migraine patients were abnormally sensitive to roll tilt (a misalignment of the eyes disrupting the sense of gravity and space), which co-modulates semicircular canal and otolith organ activity (this is an ability to sense gravity and sense motion), but not to motions that activate the canals or otolith organs in isolation (where fluid in the ears stabilizers balance), implying sensitization of canal-otolith integration. (Something is off but it is not a Meniere’s Disease type problem.)
- The researchers suggest a pathogenic model where vestibular symptoms emanate from the vestibular nuclei, (the cranial center point for the vestibular nerve) which are sensitized by migraine-related brainstem regions and simultaneously suppressed by inhibitory feedback from the cerebellar nodulus and uvula, the site of canal-otolith integration.
The suggestion is simply, something is happening to the vestibular nerve which is overly sensitized to pain by the reaction of something happening to the brainstem, and the process is further sent into panic by a dysregulation of the function of the balance mechanism in the ear.
What are we seeing in this image? Vestibular migraine patients were abnormally sensitive to roll tilt
It’s an ear problem, not a Ménière’s disease problem. Vestibular migraine patients were abnormally sensitive to roll tilt (a misalignment of the eyes disrupting the sense of gravity and space), which co-modulates semicircular canal and otolith organ activity (this is an ability to sense gravity and sense motion), but not to motions that activate the canals or otolith organs in isolation (where fluid in the ears stabilizers balance), implying sensitization of canal-otolith integration. (Something is off but it is not a Meniere’s Disease type problem.)
Why does the treatment protocol include antidepressants, antiepileptics, beta-blockers, and physical therapy? Some may find this treatment successful. People with neck pain and instability may not.
As we are quick to point out. Many people do well with many treatments for vestibular migraine and spontaneous vertigo. People who do well with medications are typically not the people we see in our office. Medications do not work for everyone.
Let’s examine a May 2020 study (6) from the Department of Otolaryngology-Head and Neck Surgery, Medical University of South Carolina. In this study, researchers sought to identify patient factors that influence response to therapy in patients with vestibular migraines. In other words, what could make the treatment work better, what factors would predispose a patient to a less than optimal response to treatment?
- 47 patients evaluated for the treatment of definite vestibular migraine
- Interventions: A protocol of antidepressants, antiepileptics, beta-blockers, and vestibular rehabilitation. Patients failing initial therapy received botulinum toxin per the PREEMPT (before the migraines start) protocol. Vestibular rehabilitation (physical therapy to improve balance and problems related to dizziness.)
What happened to the 47 patients?
- Of the 47 patients who underwent therapy for vestibular migraine. This population had a significant dizziness handicap inventory (a measuring score) reduction with therapy.
- This worked especially better for women, patients with comorbid benign paroxysmal positional vertigo, and high initial dizziness handicap inventory was significantly associated with a greater reduction in dizziness handicap inventory scores.
Neck pain and oscillopsia did not respond as well
- Conversely, cervicalgia and oscillopsia were significantly associated with a lower reduction in dizziness handicap inventory scores.
Are neck pain and cervical spine instability a possible cause of your vestibular migraine and spontaneous vertigo – migraine-associated vertigo?
We suggest one possible answer for this, not the only one. We feel an examination of cervical spine instability may lead to an answer.
When there is pressure on the brain stem, and this pressure can be exerted by hypermobility of the cervical spine vertebrae, this can result in health problems or diseases of the brainstem which can result in abnormalities in the function of cranial nerves. These would be the problems we spoke about earlier surrounding visual disturbances, pupil abnormalities, vestibular and headache symptom severity, hearing problems, vertigo, swallowing difficulty, among other challenges. In our case, we may explore what is happening throughout the cervical spine with attention to cervical vertebrae where Cranial Nerve VIII (Vestibulocochlear nerve) is comprised of the cochlear nerve (hearing) and the vestibular nerve (sense of space, balance) moves from the ear to the brain stem.
Regenerative Medicine Injections
Prolotherapy is an injection technique that stimulates the repair of unstable, torn, or damaged ligaments. When the cervical ligaments are unstable, they allow for excessive movement of the vertebrae, which can then restrict blood flow to the brain, pinch on nerves (a pinched nerve causing Vestibular migraine and spontaneous vertigo), and cause other symptoms associated with joint instability, including cervical instability.
Treating cervical ligaments – published research from Caring Medical
In our 2014 research headed by Danielle R. Steilen-Matias, PA-C, We also noted that when the cervical ligaments are injured, they become stretched out and loose. This allows for excessive abnormal movement of the cervical vertebrae.
- In the upper cervical spine (C0-C2), this can cause symptoms such as nerve irritation and vertebrobasilar insufficiency with associated vertigo, tinnitus, dizziness, facial pain, arm pain, and migraine headaches.
Treating and stabilizing the cervical ligaments can alleviate the problems of Vestibular migraine and spontaneous vertigo by preventing excessive abnormal vertebrae movement, the development or advancing of cervical osteoarthritis, and the myriad of problematic symptoms they cause.
