[Familial hemiplegic migraine].

Hemiplegic migraine (HM) is a rare subtype of migraine with aura which prevalence is about 0.01%. The characteristic features include motor symptoms (hemiparesis) along with the signs of migraine with typical aura (visual, sensory and/or speech disturbances). The diagnosis of familial hemiplegic migraine (FHM) is established when at least 1 or more relatives of the 1 or 2 degree in the family have the attacks of HM. This report describes a family in which two members (father and daughter) develop attacks of severe headache with nausea and, sometimes, vomiting, accompanied by visual disturbances, speech impairment, followed by unilateral numbness and weakness of extremities. The diagnosis of FHM was established. The report includes the review of literature and the discussion of some aspects of differential diagnosis.
