Familial or sporadic hemiplegic migraine
A rare variety of migraine with aura characterized by the presence of a motor weakness during the aura. There are two main forms depending on the familial history: patients with at least one first- or second-degree relative who has aura including motor weakness have familial hemiplegic migraine (FHM); patients without such familial history have sporadic hemiplegic migraine (SHM).
