Beginning Signs of a Stroke: Transient Ischemic Attack

A person who develops transient ischemic attack (TIA) will have temporary deficiency in the blood supply that supports the brain. People with this condition can last for minutes, hours or a couple of days. A TIA episode is similar to the origins of ischemic strokes.

TIAs cases are due to atherosclerosis — when bad cholesterol begins to develop plague in your arteries. When plaque develops in your arteries, it will decrease the pathway of blood flow, causing diseases or conditions. If the plaque breaks off and lodges itself in a small artery, then it can affect your brain. If a blood clot or fragmented plaque blocks the blood flow, it can result in TIA.

Symptoms of Transient Ischemic Attacks

The signs and symptoms of TIA are similar to ischemic strokes; however, symptoms do not stay. A TIA episode may repeat itself the same day or at a later time. Symptoms may include sudden numbness in the face, leg or arm; lack of coordination with your limbs; vision loss or double vision; difficulty speaking or understanding others; severe dizziness; and difficulty walking.

Risk Factors of Transient Ischemic Attacks

Various conditions can increase your risk of developing TIA. High-risk factors of people developing TIA are people who have high-blood pressure, smoke cigarettes, diabetes and abnormal cholesterol levels. Cardiovascular diseases can contribute in the development of TIA, such as congestive heart failure, heart attacks, heart valve disease or people who had a valve replacement. In addition, people with irregular heart rhythm (atrial fibrillation) can develop TIA. African-Americans are at risk of developing TIA than white Americans because they have a higher prevalence of developing diabetes and high-blood pressure. You are at a risk of getting TIA if your family or siblings have had the condition in the past.

Treatments for Transient Ischemic Attacks

TIA should be regarded as the warning signs of a stroke occurring. The purpose for treating TIA is to prevent the condition from recurring. People with both high blood pressure and TIA will receive medication to lower elevated blood pressure levels. If you do not have high-blood pressure, your doctor may prescribe you to take antiplatelet. This medication will reduce the tendencies of blood clots and antiplatelets are commonly found in aspirin. Your doctor may prescribe you to take a combination of medications such as aspirin and dipyridamole (Aggrenox). If both prove to be ineffective, your doctor may prescribe and monitor the dosage of taking clopidogrel (Plavix) or ticlopidine (Ticlid).
