Stroke, Transient Ischemic Attack, and Subarachnoid Hemorrhage T2 Tintinalli's Emergency Medicine Manual, 7e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-178184-8 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=56278585 RD 2024/03/28 AB Stroke is defined as any disease process that interrupts blood flow to the brain. Ischemic strokes (87%) are more common than hemorrhagic intracerebral (10%) and a traumatic subarachnoid hemorrhage (SAH) (3%) (Table 141-1). A transient ischemic attack (TIA) is a transient neurologic deficit that typically lasts less than 1 to 2 hours, but duration can no longer be used to discriminate between TIA and stroke; they are best thought of as similar disease processes on a continuum.
