- What Can Be Done for Strokes?
-

- ------------------------------------------------------------------------------
-
- QUESTION: Our neighbor is now a patient in the local hospital, the victim of
- a stroke that has left him paralyzed on the right side. It was all so sudden,
- without warning. If all strokes come on so swiftly, and I believe they do,
- how can they be prevented? Is there any medication that has been developed
- that can help forestall the terrible events we just witnessed?

- ANSWER: Strokes, or the longer medical term "cerebrovascular accident" (CVA)
- can be a frightening experience, since they often occur without warning.
- There are many causes of such happenings, but the general term of "stroke" is
- usually applied to the event that is caused by a blockage in an artery of the
- brain. The blood flowing through these vessels is the source of both
- nutrition and oxygen for the delicate tissues of the brain. When the blood
- flow is cut off, the brain cells die and stop functioning, causing all the
- familiar signs of stroke.
- Sometimes there are warning signs of a possible impending stroke. The
- symptoms are numbness in the arms and legs, muscle weakness, disturbances in
- vision and slurring of the speech. The episodes may last from 2 to 3 minutes
- or as long as 30 minutes or more, but the patient is never unconscious. These
- episodes are labeled as "transient ischemia attacks" or TIA's and require
- medical care and a complete workup to determine the exact cause. Treatment,
- including surgery, can prevent the impending stroke.
- Since the artery blockage which causes the stroke, is frequently the
- results of blood clots either forming in the vessels (due to atherosclerosis)
- or being carried there from some other site (embolism), like the valves of the
- heart, prevention of a CVA can be accomplished by preventing the formation of
- the clots. Two medications have received the major focus of such
- investigations, aspirin and warfarin. Aspirin seems most useful in reducing
- strokes from clots due to atherosclerosis. Warfarin, which reduces the
- blood's ability to clot, seems most effective in reducing blood clots that
- develop in the chambers of the heart.
- Treatments must be tailored to the individuals needs of the patients,
- based upon their unique problem and therefore must be managed by competent
- medical practitioners.
