Don’t be fooled by the name ‘Migraine Associated Vertigo’ or ‘Vestibular Migraine’ there is no scientific proof that migraine is the cause of these conditions, they are simply ‘bucket’ diagnoses you are given if you fail to be diagnosed with something else and fit the criteria. The underlying etiology of these conditions has not been determined by medicine. Anyone who tells you migraine is the cause is simply following dogma. At most it’s a popular hypothesis that conveniently allows a neurologist to prescribe some pills and send you our the door!!
I have had both ‘episodic’ and constant symptoms and the ‘episodic’ ones fall into two categories. Definitely I used to get scary 14 or so hours long migraines where I would have huge motion intolerance that meant I would become extremely nauseous if I moved my gaze even an inch from one spot on the wall. Extremely scary. Then I’ve had other attacks where I simply feel like I’m being pulled down to the floor by a magnet in my head or I begin to spin and feel a rush in my head. These latter attacks bear no resemblance to any description of migraine.
I’ve also had company constant or long lasting symptoms , motion intolerance, dizziness, marshmallow floor where the ground constantly feels soft beneath you, nausea, fluctuating severe to mild imbalance, hallucination of rocking side to side which when at its worst was visual. Add fluctuating persistent tinnitus on top of all that and it’s quite a lovely condition!!
