A hemiplegic migraine is a rare type of migraine that causes symptoms which mimic a stroke, including paralysis or weakness in one side of the body and disturbances in speech and vision, according to Healthline. The two types of hemiplegic migraines are familial hemiplegic migraines and sporadic hemiplegic migraines.
Hemiplegic migraines are a subtype of the migraine-with-aura group, says WebMD. Auras are symptoms that precede a migraine and include temporary disturbances to vision, speech and language, hearing, and muscle control. Individuals suffering from hemiplegic migraines typically present with aura symptoms that cause muscle weakness and temporary paralysis of one side of the body.
The difference between the types of hemiplegic migraines is the cause of the condition. Familial hemiplegic migraines are passed down genetically, says Healthline. Sporadic hemiplegic migraines occur in people who have no family history of these migraines and no genetic indicators for the disorder.
