Can migraines cause paralysis? Hemiplegic migraine is a rare and serious type of migraine headache. Many of its symptoms mimic those common to stroke; for example, muscle weakness can be so extreme that it causes a temporary paralysis on one side of your body, which doctors call hemiplegia.
What triggers a hemiplegic migraine? Triggers that can cause an episode of hemiplegic migraine include certain foods, certain odors, bright light, too little or too much sleep, physical exertion, stress, or minor head trauma. A cerebral angiography can also trigger an episode.
Do hemiplegic migraines ever go away? Both familial and sporadic hemiplegic migraine often begin in childhood. The symptoms can last for hours to days or even weeks in rare cases, but most will go away completely.
Should I be worried about hemiplegic migraine? An attack can be frightening for the person experiencing it, especially if it’s their first attack. Many people become worried because the symptoms can be quite similar to those of a stroke. However, hemiplegic migraine itself is not the same as a stroke and very rarely dangerous. Hemiplegic migraine is also treatable.
