Vestibular migraine (VM) is vertigo associated with a migraine, either as a symptom of migraine or as a related but neurological disorder; when referred to as a disease unto itself, it is also termed migraine-associated vertigo (MAV), migrainous vertigo, or migraine-related vestibulopathy.
A 2010 report from the University of British Columbia published in the journal Headache said that it "... is emerging as a popular diagnosis for patients with recurrent vertigo. Even though some authors believe that 'migraine associated vertigo,' is neither clinically nor biologically plausible as a migraine variant." Epidemiological studies leave no doubt that there is a strong link between vertigo and migraine.
Benign paroxysmal positional vertigo - Migraine is commonly associated with BPPV, the most common vestibular disorder in patients presenting with dizziness. The two may be linked by genetic factors or by vascular damage to the labyrinth.
Ménière's disease - There is an increased prevalence of migraine in patients with Ménière's disease and migraine leads to a greater susceptibility of developing Ménière’s disease. But they can be distinguished. Ménière's disease may go on for days or even years, while migraines typically do not last longer than 24 hours.
Motion sickness is more prevalent in patients with migraine.
Psychiatric syndromes Dizziness and spinning vertigo are the second most common symptom of panic attacks, and they can also present as a symptom of major depression. Migraine is a risk factor for developing major depression and panic disorder and vice versa.
Vertigo is a medically recognized term for the symptom of vestibular system disturbance. It may include a feeling of rotation or illusory sensations of motion or both. The general term dizziness is used by nonmedical people for those symptoms but often refers to a feeling of light-headedness, giddiness, drowsiness, or faintness, all of which must be differentiated from true vertigo, since the latter symptoms might have other causes.
