Medical Advancements in the Fight Against
Alzheimer's
One in three people in the United
States of America know someone who has been afflicted with
Alzheimer's disease. These people are the ones who can explain
exactly how devastating the disease can be to not only the
person that is afflicted, but also those who love the patient
and care for them. Since the disease can cause so much pain,
many have joined in the fight against Alzheimer's, making
contributions to research organizations and struggling to learn
more about the disease that can make a person forget who they
are. At the forefront of these contributions come many new
studies showing promise for the future with regards to
Alzheimer's. In this article, we'll discuss some of the
advancements that have been made recently with regards to
Alzheimer's disease.
One recent discovery in the field of medicine has shown
doctors a little more about how the disease actually attacks
the body. Since the disease was discovered, we've known that a
build-up of plaque is present in the brain of a person who is
afflicted with Alzheimer's. This is the only sure-fire way of
diagnosing if a patient has the disease, and it can only be
checked for when the individual is deceased via an autopsy.
Doctors in Quebec have recently learned a fundamental reason
for which the plaque may be developing in Alzheimer's patients,
and this explanation can lead towards more accurate ways of
fighting the disease. The researchers discovered that there is
a type of cell present in the brain that are known as
microglia. They discovered that these cells were, in fact, the
body's natural way of defeating the plaque that Alzheimer's is
known for. However, in those afflicted with the disease, the
microglia appears to be unable to fight off the plaques. For
that reason, the plaque can multiply and grow, leading to the
eventual complete loss of the patient's mental processes.
Upon this discovery, the researchers realized that curing
Alzheimer's may rely on finding ways for the microglia to
successfully fight off the plaque. For a solution, they turned
to a different type of microglia found in a different part of
the body - inside bone marrow. Employing the use of mice to
test their hypothesis, the scientists were pleased to find that
the microglia from the bone marrow successfully fought off the
plaque caused by Alzheimer's.
This shows a remarkable amount of promise for the future of
Alzheimer's research; eventually, the scientists hope to be
able to take stem cells from a patient and then use those cells
to aid the microglia already in the brain, forming a
fighting-force to eliminate the plaque. The researchers also
stressed that the use of anti-inflammatory drugs in order to
treat Alzheimer's should be avoided, as it may interfere with
the microglia trying to do their job.
While eliminating the plaque associated with Alzheimer's
isn't a complete solution for the disease, if successful in
human trials, it will allow patients to live with the disease
for a longer period of time without as much cognitive
loss.
