Question 6#

The most common cause of ischemic stroke is:

A. Carotid artery disease
B. Idiopathic
C. Cardiogenic emboli
D. Lacunar

Correct Answer is C

Comment:

Ischemic strokes are due to hypoperfusion from arterial occlusion or, less commonly, to decreased flow resulting from proximal arterial stenosis and poor collateral network. Common causes of ischemic strokes are cardiogenic emboli in 35%, carotid artery disease in 30%, lacunar in 10%, miscellaneous in 10%, and idiopathic in 15%. The term cerebrovascular accident is often used interchangeably to refer to an ischemic stroke.
