Alzheimer’s disease (AD) is the most common cause of
dementia, which is a progressive condition where the brain loses nerve cells
causing memory loss and impairment in other areas of cognition, such as the
ability to perform activities of daily living (finances, chores, drive, etc).
There is an estimated 30 million people worldwide with Alzheimer’s disease. The
underlying causes are not fully understood, but researchers have identified
genes associated with AD, as well as others that clearly increase the risk of
development.
Diagnosis is often very difficult. Definite diagnosis is
often only confirmed by brain biopsy. Interestingly, in the past one to two
years, significant advances in diagnosis have been found or approved. One is,
by performing a lumbar puncture, or “spinal tap” (visit Colonial Neurology and click: “Lumbar Puncture Test Information”), which we at Colonial
Neurology do on a routine basis, and sending fluid obtained for special
testing. This fluid can show changes in certain proteins many years before
symptoms even begin. It is not part of routine screening or testing though.
There also are newly approved brain scanning techniques that have been shown to
be very helpful in diagnosing AD.
Diagnosing is one thing, but what is even more important is
the ability to treat. Treatments are often of mild help. There have been
several studies suggesting whether one has “normal aging”, mild cognitive
impairment, or dementia, progression from one stage to another can be
significantly slowed with one easy to tolerate treatment regimen –
cardiovascular EXERCISE, such as brisk walking, jogging, or using an arm bike
in those with limited mobility! There are pharmaceutical medications and foods
considered approved treatments, but in the next 5-10 years, we expect a true
breakthrough in treatment and prevention! See your doctor today if you’re
concerned about your memory or about your risk for Alzheimer’s disease! And be
fit, as exercise is the best prescription to prevent Alzheimer’s!
