Question: What is a Migrainous Infarction?
Answer:
A migrainous infarction is one of the complications of migraine headaches. According to the International Headache Society, it consists of "one or more migrainous aura symptoms associated with an ischemic brain lesion in appropriate territory demonstrated by neuroimaging." During a migraine with aura, a patient also has a stroke in the area of the brain from which the symptoms of the aura occur.
For a migraine to fit the criteria for Migrainous Infarction, it must include the following:
If your symptoms are not like your usual migraine aura, call your health care provider. He or she can instruct you on what you should do next. If you feel that you are experiencing a stroke, call 911 immediately. If you are having a stroke, early medical treatment may help you limit the amount of permanent damage that is done.
