The most common symptoms of a transient ischemic attack include weakness, numbness or paralysis of the face, arm or leg, which usually affects one side of the body, according to Mayo Clinic. Additional TIA symptoms include slurred speech, blindness in one or both eyes, dizziness and loss of balance.
TIA symptoms vary depending on what part of brain is affected, explains Mayo Clinic. Attacks generally last only few minutes, and symptoms tend to recede within an hour. A TIA, or mini stroke, occurs when a blood clot or some other obstruction reduces or blocks blood flow to the brain, notes WebMD.
