Alzheimer's Treatment: Medications and Vitamin E
Alzheimer's treatment overview:
Currently there is
no Alzheimer's treatment that can prevent or halt the mental decline
associated with Alzheimer's disease. Many drugs have been tested, but
most have been abandoned, or found to be ineffective or even toxic in
their use as an Alzheimer's treatment. Most of the more effective
drug therapies have focused on preventing the destruction of neurons,
with the ultimate goal of preventing the decline of memory functioning
for as long as possible.
One theory that
drives research in the area of Alzheimer's treatment involves the
belief that memory deficits in Alzheimer's disease are in part a
deficiency in the neurotransmitter acetylcholine. Medical scientists
have continued to try to boost the amount of acetylcholine in the
brain by administering substances containing it, and by stimulating
the brain to manufacture it in increasing amounts, or by preventing
the breakdown of the limited quantities of acetylcholine that the
brain is able to make on its own. Lecithin and Choline, which are
substances that appear naturally in many foods, are used by the body
to produce acetylcholine. Both Lecithin and Choline have been given
in supplement form to Alzheimer's patients in the hope of improving
their mental functioning, but have had very disappointing results at
the present time.
Alzheimer's
treatment - Cholinesterase inhibitors:
Some of the more
recently reported Alzheimer's treatments include the cholinesterase
inhibitors, which were the first medications approved by the U.S. Food
and Drug Administration (FDA). These medications include tacrine
(Cognex), donezepil (Aricept), rivastigmine (Exelon), and galantamine
(Reminyl) and most recently memantine (Namenda) which slow the
breakdown of acetylcholine. While they may reduce some the mild
symptoms associated with Alzheimer's disease, they do not prevent or
in any way halt its progression. They merely delay the progression of
the disease. According to guidelines published by the American
Academy of Neurology in 2001, these medications are consistently
better than placebo, but the average benefit is relatively small and
the disease continues to progress despite the treatments.
Alzheimer's
treatment and Vitamin E:
The New England
Journal of Medicine published an article in 1997 related to the study
of the antioxidant properties vitamin of E. It was found in that
research that patients with moderately severe Alzheimer's disease
received a daily dose of 2000 IU of vitamin E, 10 mg a day of
selegeline, (a medication used for Parkinson's disease treatment),
both, or a placebo. Vitamin E or selegeline seem to slow the time to
institutionalization and increase survival by approximately 7 months.
The number of individuals losing their ability to do daily activities
such as bathing or handling money was cut by one quarter. Combining
vitamin E with selegeline did not improve the results.
The American
Academy of Neurology concluded that based upon the study that there is
good evidence to support the use of vitamin E in an attempt to slow
the progression of the Alzheimer's disease process. The evidence for
selegiline to do the same was found to be weaker and there is no real
advantage to using selegiline if vitamin E is already being used in an
individual’s Alzheimer's treatment.
An important fact
to note in the use of vitamin E as an Alzheimer's treatment is that
while it is generally safe, large doses have been associated with
bleeding in some individuals.
