The correct answer is  Answer is A (Embolism): The most common cause of cerebrovascular accidents is embolism. Harrisons 16th has not classified ischaemic strokes into thrombotic and embolic events but into Atherosclerosis (4%), cardioembolic (17%), & others (64%). Neveheless even others (64%) include most commonly embolic events other than those of cardiac origin such as 'aery to aery embolic strokes' etc. and hence the answer stays the same.
