- Alzheimer's Disease: Frequency and Causes

- QUESTION: I have just learned of another person with Alzheimer's Disease,
- this time a member of our own family. I don't understand where this disease
- came from, for I surely never heard of it years ago. Could it be the result
- of an infection like AIDS, another disease that was not known when I was just
- a girl? Perhaps you could shed some light on this new epidemic.

- ANSWER: Your perceptions are correct, there are many more cases of
- Alzheimer's diagnosed today than in the past. Alzheimer's is one of two
- illnesses that account for the largest number of dementia cases now seen. It
- is diagnosed in 50 percent to 60 percent of all cases, with multi-infarct
- dementia responsible for another 10 percent to 20 percent. During the last
- century, such situations were rare, as few people reached the age of 75 years.
- Today, in the United States, more than half the population attains the age of
- 75, and more than 25 percent live to the age of 85. That leads to the
- astonishing fact that, at present, there are more than 2.6 million people with
- dementia in our country, a number that is expected to reach more than 4
- million by the year 2000, and as many as 1 in 30 Americans (almost 9 million)
- by 2040. Thus it is a developing problem with far reaching implications for
- the future.
- The cause of the disease is not yet fully understood, but present
- thinking does not include infection as one of the possibilities. The only
- well established risk factor is that of age. There may be a genetic link, for
- a history of Alzheimer's in the family increases risk about 4 fold. Another
- link may be to aluminum, for it is found in brain cells of Alzheimer patients
- in elevated amounts. But it is not clear whether the aluminum accumulates in
- cells that are already altered by the disease, or whether this substance is
- acting as a toxin that causes the illness. Previous head trauma may be
- another risk factor, since statistics reveal that such injuries increase the
- possibility of Alzheimer's by 2.8 times. It is clear that there is a real
- need for much more research in this area, if the increasing number of cases is
- to be reduced.
