A "TIA" (Transient ischemic attack ) is transient stroke that lasts only a few minutes. It happens when the blood supply to a certain part of the brain is briefly interrupted. Most symptoms of a TIA disappear within an hour, although they may persist for up to 24 hours. Symptoms include: numbness or weakness in the face, leg or arm, especially on one side of the body, confusion or difficulty in talking, trouble in seeing with one or both eyes, difficulty with walking, dizziness, loss of balance and coordination. Drug therapy to reduce the risk of stroke is recommended for people experiencing these symptoms. TIA treatment includes antiplatelet agents, especially aspirin. People with an irregular heartbeat might also be prescribed anticoagulants.
