What Is a Migrainous Infarction?

A migrainous infarction is a rare condition that occurs when a blood clot forms in the brain during a migraine attack. This can lead to a stroke-like episode, with symptoms such as sudden numbness or weakness on one side of the body, difficulty speaking or understanding speech, and vision problems. Migrainous infarctions are thought to be caused by a combination of factors, including the intense pain and inflammation associated with migraines, as well as changes in blood flow in the brain. Treatment typically involves medications to dissolve the blood clot and reduce inflammation, as well as supportive measures such as physical therapy and speech therapy.
