A Hemiplegic Migraine
It is a rare but severe form of a Migraine that can cause temporary paralysis on one side of the body either before or during a headache. Symptoms such as a stabbing or pricking sensation, vertigo, and problems swallowing (jaw pain), speaking, or seeing, may start before a headache, and stop shortly after that.
Familial Hemiplegic Migraines are the headache migraines that run in the family. However, they are rare! To date, researchers have identified three distinct forms of the Familial Hemiplegic Migraines. The genetic mutations make the brain more excitable or sensitive, probably by increasing the levels of glutamate in the brain.
