· Rotational vertigo
· Subjective vertigo
· Positional vertigo
· Instability/hypersensitivity to visual stimuli
How is it diagnosed?
Diagnosis is purely anamnestic and requires a clinical history of at least 5 episodes of vertigo in a patient with an established diagnosis of migraine (according to IHS criteria), lasting from 5 minutes to 72 hours, accompanied in at least 50% cases by photophobia and/or headache with migraine signs and/or visual aura.
· Collection of medical history
How is it treated?
Treatment is mainly aimed at preventing vertigo attacks with drugs (flunarizine, cinnarizine and dimenhydrinate, beta-blockers, calcium channel blockers, antiepileptics, antidepressants). Anti-inflammatory drugs and/or vestibulodepressants may be used (only for a short time and only for one episode of vertigo) in acute crises.
