The brain controls how our body functions, how we think, how we see, how we talk, and how we move. The signals to and from the brain are transmitted through the spinal cord to the rest of the body A transient ischemic attack (TIA) is a transient stroke that lasts only a few minutes. It occurs when the blood supply to part of the brain is briefly interrupted. TIA symptoms, which usually occur suddenly, are similar to those of stroke but do not last as long. Most symptoms of a TIA disappear within an hour, although they may persist for up to 24 hours.
Symptoms can include: numbness or weakness in the face, arm, or leg, especially on one side of the body; confusion or difficulty in talking or understanding speech; trouble seeing in one or both eyes; and difficulty with walking, dizziness, or loss of balance and coordination. To help prevent TIA, stroke, or heart attack, your provider may prescribe antiplatelet agents, drugsthat prevent platelets from clumping; or anticoagulants (blood thinners), drugs that prevent blood from clotting. Many drugs, herbs, and dietary supplements interact with these types of medications. Talk to your doctor and pharmacist. These drugs include: • Low-dose aspirin • Ticlopidine (Ticlid) • Clopidogrel (Plavix) • Dipyridamole and aspirin (Aggrenox) • Warfarin (Coumadin) Each year, approximately 449,950 strokes occur in the Netherlands. NINDS is the leading supporter of research on stroke and TIA in the U.S. and sponsors studies ranging from clinical trials to investigations of basic biological mechanisms as well as studies with animals.
