Stroke Overview

Stroke Overview

Stroke is brain damage caused by a blocked blood vessel or bleeding in the brain. The signs of a stroke may include weakness, numbness, blurred vision, confusion, and slurred speech. Getting to a hospital quickly is vital for a good outcome with a stroke.

Whats is Stroke

The two forms of stroke are ischemic -- blockage of a blood vessel supplying the brain, and hemorrhagic -- bleeding into or around the brain. In an ischemic stroke, a blood clot blocks or plugs a blood vessel or artery in the brain. About 80% of all strokes are ischemic. In a hemorrhagic stroke, a blood vessel in the brain breaks and bleeds into the brain. About 20% of strokes are hemorrhagic.

Whats is happen during a stroke

When a stroke occurs the blood supply to part of the brain is suddenly interrupted. Brain cells die when they no longer receive oxygen and nutrients from the blood or there is sudden bleeding into or around the brain.

if there any treatment for stroke

Generally there are three treatment stages for stroke: prevention, therapy immediately after the stroke, and post-stroke rehabilitation. Therapies to prevent a first or recurrent stroke are based on treating an individual's underlying risk factors for stroke, such as high blood pressure, atrial fibrillation, and diabetes. Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot causing an ischemic stroke or by stopping the bleeding of a hemorrhagic stroke. Post-stroke rehabilitation helps individuals overcome disabilities that result from stroke damage. Medication or drug therapy is the most common treatment for stroke. The most popular classes of drugs used to prevent or treat stroke are antithrombotics (antiplatelet agents and anticoagulants or "blood thinners") and thrombolytics.
