ABSTRACT
The American Stroke Association now advocates a definition of stroke that incorporates the findings of brain imaging so that stroke is defined as an episode of focal neurologic (brain, retina, spinal cord) dysfunction (even if less than 24 hours in duration) in which the autopsy, computed tomography (CT) brain scan, or magnetic resonance imaging (MRI) brain scan shows features con sistent with focal brain infarction (265-267) or hemor rhage (268-271, next page).
