TIA: Common Symptoms of Transient Ischemic Attack

Thursday, 10 April 2014 01:26 AM

Transient ischemia attack occurs when flow of blood to a part of the brain stops temporarily. Patients suffering from TIA experience symptoms similar to the symptoms of a stroke for up to 24 hours. In most of these cases, stroke-like symptoms may only remain for one to two hours. TIA symptoms are warning signs that an actual stroke may occur if no preventive measures are taken. more than 10 percent of patients of transient ischemic attack may have a stroke within three months. However, TIA is different from a stroke.
Unlike a stroke, a transient ischemic attack does not cause brain tissue to die. In this case, the blockage breaks up quickly and then dissolves. High blood pressure can increase the risks of a stroke or a transient ischemic attack. A family history of stroke is also one of the major risk factors. Race is considered a risk factor, as African-Americans are more likely to get a stroke. Patients suffering from heart diseases or poor bloodflow in the legs are also likely to suffer from a transient ischemic attack.  
Warning Signs and Symptoms of a Transient Ischemic Attack 
Signs and symptoms of TIA are similar to the signs and symptoms of a stroke. However, these symptoms are always temporary but are strong warning signs of a possible stroke in the future. Most of the signs of a transient ischemic attack disappear within an hour or two. In repeat episodes, the recurrent signs may be similar or differ from those of the past attacks. Diagnostic tests can determine whether the symptoms indicate a stroke or TIA.
Changes in brain MRI or head CT scan are present only in case of a stroke. On experiencing any of the signs given below, patients should seek immediate medical help. Doctors perform many other tests to check if the signs are those of a stroke. Signs and symptoms occur suddenly and may last for a short period ranging from a few minutes to a few hours.
