TIA or Stroke?

Transient Ischemic Attacks (TIAs) are a warning sign of a future stroke. Sometimes referred to as a mini-stroke because the symptoms are like a stroke but do not last long. A TIA occurs when the blood flow to a part of the brain is blocked or reduced, most often from a blood clot. After a short time, the blood flows again and the symptoms disappear. With a stroke the blood flow does not resume and there is permanent damage to the brain cells.

TIAs need to be taken seriously, and prompt medical attention is strongly advised.

Symptoms of a TIA are similar to a stroke — generally a sudden numbness or weakness of the face, arm or leg on one side of the body. A person may also experience confusion, trouble speaking or understanding, trouble seeing, walking, dizziness or loss of balance.

Call 911 if you experience any of these symptoms or see these symptoms in someone else. A medical professional needs to evaluate whether it is a stroke or a TIA.

Prevention of a future stoke is the goal in treating someone who has experienced a TIA. Testing will be done to determine the exact cause of the blockage. Lifestyle changes will be recommended, including diet and exercise, quitting smoking and limiting alcohol. Medications may be ordered to treat high blood pressure, high cholesterol or heart disease, as well as prevention of blood clot formation or other conditions found on exam.

Be safe and let someone know if you experience any symptoms of a TIA.Source: http://www.stroke.org/site/PageServer?pagename=tia&printer_friendly=1
