Forgetful? Don't Assume It's Alzheimer's Disease

Ronald C. Peterson, MD, PhD, also feels that Waldemar's numbers are probably
on target. He says that the study is important in terms of reminding American
physicians that there are treatable causes of memory loss. Peterson is
professor of neurology at the Mayo Medical School in Rochester, Minn.
In addition to depression as a reversible cause, Waldemar says, "Thyroid
disease and nutritional problems were also identified as a cause of mild memory
disorders." Another cause was a problem with brain-fluid circulation, which
is corrected by surgery. A small number of patients also had alcohol dependence
as a cause, she adds.
Waldemar says the current study was "just an identification study. We
have no data on the effect of treatment." She says, however, that she and
her colleagues are now conducting a treatment study.
- Researchers from Denmark report that in their test group of patients
showing minor memory problems, Alzheimer's disease was to blame in fewer than
half the cases. About 20% of the patients had problems that could be reversed
- Experts note the 20%-reversible rule is probably true the world over.
Depression is the most common reversible culprit, but thyroid disease, stress,
and a brain-fluid circulation problem also can mimic Alzheimer's disease.
- People often fear telling their doctors about the symptoms they may be
experiencing, but experts say it's important to seek help because, many times,
treatment can be successful.
