Overview
Definition of Transient ischemic attack
According to American stroke association, transient ischemic stroke is defined as a transient episode of neurological dysfunction caused by a focal brain, spinal cord, or retinal ischaemia, without acute infarction.[1]
Pathophysiology
The pathophysiologic mechanism of transient ischemic stroke may include temporary blockage of cerebral large or small blood vessel due to atherothrombotic or embolic cause followed by complete resolution of symptoms within few hours of onset. There may be mild tissue ischemia and hypoxia responsible for transitory symptomatology of patient. The specific clinical presentation of the patient correlates with the area of brain affected due to ischemia[1][2]
