Signs and symptoms of a TIA include weakness or numbness in the extremities or on one side of the body; sudden confusion, speech difficulties or an inability to understand what others are saying; and sudden visual disturbances, according to Everyday Health. A sudden, severe headache and dizziness with loss of balance or coordination are additional symptoms. The difference between a TIA and a stroke is one of duration. TIA symptoms resolve rapidly and leave no permanent brain damage.
TIAs occur when the blood supply to the brain is temporarily cut off due to a narrowed or blocked artery, notes Mayo Clinic. This is usually due to atherosclerosis, the build up of cholesterol-laden plaques in the arteries. It may also be caused by blood clots. Other risk factors include a family history of stroke, advancing age, a history of cardiovascular disease, a history of diabetes and the presence of high levels of the amino acid homocystine in the blood. Hypertension, high cholesterol, obesity and a sedentary lifestyle also increase risk.Learn more about Conditions & Diseases
