Migraine associated vertigo can have these effects : "dizziness; motion intolerance with respect to head, eyes, and/or body; spontaneous vertigo attacks (often accompanied by nausea and vomiting); diminished eye focus with photosensitivity; sound sensitivity and tinnitus; balance loss and ataxia; cervicalgia (neck pain) with associated muscle spasms in the upper cervical spine musculature; confusion with altered cognition; spatial disorientation; and anxiety/panic." Migraine Associated Vertigo
"Migraine-associated vertigo (MAV) is a syndrome consisting of dizziness and/or vertigo that is suspected to be related to migraine. Many patients diagnosed with MAV do not have headaches, or have chronic non-specific headaches that don't fit into the migraine classification developed by the International Headache Society. The cause of this condition is unknown but progress is being made through clinical experience and genetic research. This condition was previously rarely diagnosed, but is now proving to be one of the most common causes of chronic dizziness and/or recurrent vertigo. Sufferers often describe chronic dizziness and dysequilibrium in the form of a "rocking" sensation when still, recurrent episodes of rotational vertigo, chronic daily headaches, migraine headaches, light sensitivity, poor visual acuity and other changes in vision, visual "snow", nausea and severe motion intolerance. Many of these symptoms cannot be objectively observed or tested for, so physical and neurological examinations (including neuroimaging) are often completely normal. Patients generally do not have all of these symptoms - in fact those with chronic dizziness have quite often not experienced acute rotational vertigo or even a migraine headache. MAV is often misdiagnosed as Meniere's Disease, Vestibular Neuritis or as a psychiatric disorder. A condition previously described, known as "atypical Meniere's" is no longer recognised and is believed to be a migrainous vertigo sydnrome. " http://www.mvertigo.org/There is a category now... MAV is the old name... the new classification is vestibular migraines. Migraines with vestibular symptoms associated with them. However, some of us have many attacks outside of a migraine which is why we often use the term MAV so often because it migraine associated vertigo, with or without a migraine, nevertheless, the correct term is vestibular migraines and those of us that get vertigo bouts outside of our migraines are just more rare and they might have to broaden the category to chronic vestibular migraines in the future.
