Brain Stem Transient Ischemic Attack Definition
Brain Stem Transient Ischemic Attack: Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)
Synonym: transient ischemic attack, anterior circulation transient ischemic attack, transient cerebral ischemia, transient brainstem ischemia, crescendo transient ischemic attacks, carotid circulation transient ischemic attack, brain tia, vertebrobasilar circulation transient ischemic attack, tias (transient ischemic attack), tia (transient ischemic attack), posterior circulation transient ischemic attack.
