A sudden stopping of blood flow to a portion of the brain causing injury. Some strokes are associated with bleeding into the damaged area. Most strokes are caused by a blocked artery in the brain from hardening of the arteries (atherosclerosis) or from a blood clot that travels from another area (embolus). The symptoms experienced depend on the artery blocked. Survival and the best outcome depend on seeking medical care immediately. Also known as a Cerebral Vascular Accident (CVA).
Weakness of an arm, leg, side of the face, or any part of the body.

A stroke is a medical emergency. Therapy depends on the size of the stroke, the medications the patient is taking, how long the symptoms have been present and other associated diseases. Treatment may include: blood pressure medication, anti-platelet medications (aspirin, clopidogrel Plavix), anticoagulants (heparin, enoxaparin, warfarin), thrombolysis (tissue plasminogen activator t-PA), intravascular thrombolysis, physical therapy, speech therapy, and or occupational therapy.
