- QUESTION: My neighbor claims to have had a stroke, that, as she puts it,
- "went away" after just a day or two. When my mother had a stroke, many years
- ago, she was paralyzed on her entire left side, and died from the complication
- less than a year later. I am sure that my neighbor's doctor told her about
- the stroke condition, but I can't make sense out of it. Can you? Because of
- my own family history, I am more than a little interested in finding out all I
- can about this subject. Thank you for all your help.

- ANSWER: The possibility that a stroke will occur increases as we all grow
- older, and is a subject of interest to many people. It is not rare, as one
- study found that symptoms of stroke affected about 170 people in every 100,000
- aged 55 to 64 years, a number which grew to 957 out of 100,000 for people over
- the age of 75. Strokes (or cerebrovascular accidents--CVA's) kill about 100
- people for every 100,000 in their mid 50's, and that rate doubles with each
- additional 5 years of aging, reaching a level of 1500 deaths per 100,000
- individuals at age 80. The older you are when a CVA strikes, the more likely
- it is that it will be severe, disabling and permanent. A CVA is the result of
- either a blockage of an artery in the brain (by a clot, for example) or
- because of bleeding in the brain caused by a leak or rupture in one of the
- brain's arteries. In a large number of cases where the stoke is caused by
- blockage (approximately 1/4 to 1/3), a warning occurs. This is called a
- transient ischemic attack (TIA) and results from a temporary narrowing of the
- artery, rather than a complete permanent blockage. This gives doctors an
- opportunity to provide treatment that may prevent the total stroke, which
- occurs within a month of the TIA about 1/3 of the time, and in 1/2 the cases
- within a year. And I believe your neighbor suffered from a TIA, a small
- stroke that "goes away", but often not for long.
- The signs of a TIA are usually quite clear. The may be a temporary
- slurring of the speech, double vision, weakness on one side of the body, or
- loss of feeling in the arms or legs, usually on just one side as well. The
- patient may be unable to speak, lose coordination that affects walking or
- other movements. The symptoms result from a lack of oxygen to the cells of
- the brain due to a lack of blood circulation. In most cases the symptoms
- disappear within an hour as the artery opens up again, restoring circulation
- to the area, and the cells are not permanently damaged. While temporary
- confusion, dizziness, memory loss and fainting can be caused by other medical
- problems, a diagnosis of TIA is also possible and should be investigated.
- Thus a careful and complete examination is a must when these symptoms occur.
- The diagnosis can be made based upon history, physical examination, the
- result of electrocardiograms as well as special imaging techniques such as a
- CT Scan (computed tomography) or MRI (magnetic resonance imaging). Since the
- treatment of a TIA depends upon the determination of the cause of the TIA,
- this diligence is really necessary.
- Several kinds of treatment may be used. Aspirin is used to help prevent
- the formation of clots, and is used in dosages ranging from 325 mg/day (1
- regular strength aspirin tablet) to as low as 80 mg or even 30 mg/day (a baby
- aspirin). Some studies have used aspirin along with other medicines that
- affect coagulation. Reducing the blood's ability to coagulate with warfarin
- is another technique used frequently. When the carotid arteries are affected,
- surgery may also be considered.
