Guide To The Symptoms Of An Ischemic Stroke

An ischemic stroke is a serious medical event. It occurs when a blood clot becomes lodged in a blood vessel in the brain. Without a supply of blood, the brain cells begin to die in a matter of minutes. The underlying cause of an ischemic stroke can be from the buildup of plaque in the blood vessels or any other mechanism that can cause an embolus or clot to travel to or develop in the brain. Diagnosis of an ischemic stroke is made with a variety of tests, including physical exam, magnetic resonance imaging, and computerized tomography scans. Others are electroencephalograms, evoked potential tests, echocardiography, and angiography.
