Transient Ischemic Attack (TIA)

>> Monday, January 25, 2010

A transient ischemic attack, TIA or mini-stroke, occurs when blood supply to part of the brain is briefly interrupted. The only difference between a TIA and a stroke is that with TIA the blockage is transient or temporary.



Transient Ischemic Attack (TIA)

Most TIAs last for a few minutes and are caused by an embolus dislodged from a carotid artery atherosclerotic plaque. Presence of infarction, or tissue death, is the main distinction between a TIA and a stroke.

Symptoms vary widely from person to person, depending on the area of the brain involved with most frequent symptoms being temporary loss of vision, difficulty speaking, weakness or  numbness on one side of the body.





An estimated 350,000 TIAs occur annually in the United States, 500,000 in Europe and 130,000 in Japan. Ten percent of patients who suffer a TIA may present with a stroke within 3 months, with half of those strokes occurring within 48 hours from TIA event.
