What Causes the Vertigo Associated with Migraines?
The most commonly accepted theory regarding the pathophysiology of migraine-associated vertigo is the Cortical Spreading Depression theory (CSD). Multiple authors propose that episodes of dizziness are similar to that of a migraine aura or are actually part of the aura.
But since only about 20% of migraine sufferers actually experience an aura, researches attribute the vertigo as part of a fluctuation of nerve cell ion channels. Recent understandings in a particular type of migraine – Familial Hemiplegic Migraine (FHM) have shown two genes responsible for controlling ion flow across nerve cell membranes.
These two genes affect changes in calcium, sodium and potassium channels. This alters the electrical conduction potentials of nerve cells. The result is a transient wave front that suppresses central neuronal activity. This depression spreads in all directions from its site of origin. These changes result in a reduction in cerebral blood flow in the areas of spreading depression.
Two authors have suggested that when dizziness is unrelated to headache, the dizziness occurs from the release of neuropeptides, including substance P, neurokinin A, calcitonin and gene–related peptide [CGRP].
No single hypothesis explains the or dizziness process in migraine at this time. Thus, the causes of the symptoms of migraine remain controversial.
There is another relatively common form of vertigo called Meniere’s Disease. Meniere’s Disease is not related to migraines at all. It has a classic triad of vertigo, hearing loss and tinnitus (ringing of the ears). The vertigo of Meniere’s Disease is frequently confused with migraine-associated vertigo.
Fortunately, the vertigo associated with the more common forms of migraines rarely have any hearing loss and also does not have much in the way of tinnitus.
The is one ominous variant of migraine headaches called Basilar Migraines (or also known as Bickerstaff ‘s syndrome) which is a cross between a migraine and occasionally ends up in a stroke. Some features of Basilar Migraines include vertigo, hearing loss and tinnitus. Up to 80% of patients with Basilar Migraine have been reported to have sensorineural hearing loss.
So in the case of the Basilar Migraines, the vertigo might be indistinguishable from Meniere’s Disease during the headache-free intervals.

Clearly, Basilar Migraines are a more pernicious variety of migraine headache. Even though Basilar Migraines are classified as a sub-group of migraines, some believe that the stroke-like damage that is frequently associated with this group of headaches places it in a different category and should be treated very differently from the typical migraine.
Unfortunately, the vertigo component of migraines is extremely resistant to standard treatment. The triptan class of drugs is relatively ineffective. Also, the standard anti-vertigo drugs like meclizine and phenergan also do not work well.
A Better Method For Migraine Relief
There is another option to relieve migraine pain – a migraine cure. Cure the migraine and never worry about migraine-associated vertigo again.
Recent reports indicate migraine headaches can indeed be totally abolished – as a number of elite medical clinics catering to women have testified. Under their treatment protocols, migraines are completely eliminated in 80% of their patients.
These successes are limited to women only, as addressing a woman’s hormones is the basis of the cure. Some clinics have published their treatment protocols and even made them available to the public.
The Women’s Health Institute of Texas believes that a migraine cure certainly eliminates the migraine nausea altogether - and concern over the ensuing migraine may no longer be necessary – at least in women.
