Ischemic strokes (87%) are more common than intracerebral hemorrhage (10%) or nontraumatic subarachnoid hemorrhage (SAH) (3%) (Table 141–1). A transient ischemic attack (TIA) is a transient episode of neurological dysfunction caused by ischemia but without an acute infarction of brain tissue. TIA episodes typically lasts less than 1 to 2 hours, but duration of symptoms alone can be unreliable in discriminating between TIA and stroke as they are similar disease processes on a continuum of severity.
