People can experience more than one TIA, and symptoms may vary depending on which part of the brain is affected, explains Mayo Clinic. Episodes usually last only few minutes, and symptoms normally disappear within an hour. Regardless of severity, a person who suspects that she has had an attack should seek medical attention.

A TIA is often referred to as a mini-stroke, and it occurs when a blood clot or some other blockage reduces or blocks blood flow to the brain, notes WebMD. Attacks do not last long, blood flow returns to normal within a short time and symptoms disappear. This is in contrast to a stroke, in which blood flow remains blocked and permanent damage occurs to the brain. Although a TIA is usually short-lived, it is a warning sign of a likely future stroke.

Treatment for a TIA generally involves early testing and focusing on preventing another TIA, according to WebMD. The treating physicians may recommend medications, such as aspirin, clopidogrel, dipyridamole with aspirin, and warfarin. Prevention methods include lowering blood pressure, changing diet and controlling diabetes. In severe cases, surgery may be necessary to reopen narrow arteries.
