Hemiplegic migraine is a rare form of migraine where people experience weakness on one side of their body (hemiplegia) along with headache and other symptoms that are often the same as seen in migraine.

Hemiplegic migraine is a rare subtype of migraine with aura, characterized by the presence of motor weakness as an aura manifestation at the time of migraine attack. Typically, migraine aura has visual symptoms as aura, but occasionally impairment in sensation or speech may also be seen.

A hemiplegic migraine is a type of migraine headache that causes migraine symptoms and muscle weakness on one side of your body. Muscle weakness usually starts during the aura phase of a migraine, right before or during a headache attack.

One fairly rare subtype of migraine with aura is called hemiplegic migraine. Breaking down the term, hemi means half, and plegic means paralysis. The hallmark symptom of hemiplegic migraine is temporary one-sided weakness or paralysis.
