MSH: 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),CSP: recurring, transient episodes of neurologic dysfunction caused by cerebral ischemia; onset is usually sudden, often when the patient is active; the attack may last a few seconds to several hours; neurologic symptoms depend on the artery involved.,NCI: A brief attack (from a few minutes to an hour) of cerebral dysfunction of vascular origin, with no persistent neurological deficit.,MEDLINEPLUS: <p>A transient ischemic attack (TIA) is a <a href='http://www.nlm.nih.gov/medlineplus/stroke.html'>stroke</a> that comes and goes quickly. It happens when the blood supply to part of the brain stops briefly.
