Alzheimer’s Medication
Alzheimer’s disease is a degenerative
illness which affects the cognitive functions of the brain. This
means that as the disease progresses, the person suffering from
Alzheimer’s may end up losing his abilities to reason, learn, retain
memory, or even make judgments. In time, he will not even be able to
do simple everyday tasks that we take for granted. The symptoms just
become worse as time goes, ending inevitably in the death of the
patient.
Currently, there is no cure for
Alzheimer’s disease but there are several Alzheimer’s medications
that may provide treatment for some of the symptoms of this brain
disorder. The US Food and Drug Administration (FDA) has recently
approved five prescription drugs. These Alzheimer’s medications can
treat the symptoms of the disease, providing patients with comfort,
dignity, and independence for a longer period of time. By doing
this, these drugs will benefit not only the patient but the
caregivers as well, serving as both encouragement and assistance in
caring for their patients.
It should be noted, however, that
these Alzheimer’s medications will not stop the disease itself.
Cholinesterase Inhibitors
An interesting finding by scientists
involved in Alzheimer’s research is the substance called
acetylcholine, which is a chemical released by the brain.
Acetylcholine is said to be important for memory and thinking and
that its breakdown is part of the reason why Alzheimer’s disease
develops in an individual. Thus, the aim of scientists was to find
an Alzheimer’s medication that could somehow prevent the breakdown
of acetylcholine. That substance was called cholinesterase
inhibitors.
Cholinesterase inhibitors have the
ability to delay or prevent the symptoms of Alzheimer’s disease from
becoming worse for a limited time. In addition, it may also help
control some behavioral symptoms, such as withdrawal from human
contact and the environment, which Alzheimer’s patients exhibit
during the later stages of the disease.
From the five Alzheimer’s medications
approved by the FDA, four of them are considered cholinesterase
inhibitors. They are prescribed to treat the symptoms of mild to
moderate Alzheimer’s. These medications include:
N-methyl D-aspartate (NMDA)
Antagonist
The above four drugs only work during
the early stages of Alzheimer’s. However, if the disease is already
in its moderate to severe stages, treatment would require the
introduction of a fifth medication, known as Namenda (memantine).
This Alzheimer’s medication is an N-methyl D-aspartate (NMDA)
antagonist and is said to delay the progression of some of the
symptoms of moderate to severe Alzheimer’s disease. Namenda may
allow the patients to continue to perform their daily normal
functions a little longer.
More research is being done to
understand Alzheimer’s disease and what causes it. It is inarguable
that the deeper our insight into this disease is, the closer we are
to finding its cure.
