State the term - Migraine Stroke

Since the late 1800s, physicians have recognised that migraine attacks may lead to infarcts and permanent neurological deficits. Such migraine strokes are relatively rare compared with other types, but they are believed to account for a significant proportion of strokes in young people (under 40 years of age), especially women. The immediate cause of these strokes is probably some form of vasospasm-constriction of blood vessels-but the underlying cause of the vasospasm remains a mystery. The classic migraine stroke is experienced with a variety of neurological symptoms, including impaired sensory function (especially vision), numbness of the skin (especially in the arms), difficulties in moving, and aphasia.
