Strokes (also called cerebrovascular accidents) occur suddenly and are clinically defined as a focal vascular lesion, which causes an abrupt onset of a neurological deficit that lasts longer than 24 hours. The deficit depends on the area of brain affected. In a transient ischemic attack (TIA), the neurological deficits last less than 24 hours but are usually 5 to 15 minutes.
