ASC 128 Presentation
Today I presented the research I did on genetics and alcoholism. The
reason why I did not get into much detail referring to other drugs is because
there is not enough valued information. I think the presentation went well,
but I feel I could have done a lot better. Besides being nervous, I went
blank about five minutes before I had to get up in front of the class.
I
guess it happens to everybody. It was hard to prepare in such a short amount
of time, but I feel that I made the best out of it. I'm glad I went first
because now I'm finished.
I was really hoping that everyone got some kind of understanding of what
I was saying. From reading the evaluations, I perceived that most of the
students did understand what I was talking about, but wanting more
information relating to the subject.
I discussed what makes an alcoholic, and part of the reason is the
metabolism. Pre-alcoholics react to alcohol by wanting more because of
a
genetic difference. They lack the brake that most of us have which is
slowing down, and knowing when we have had enough. A Prealcohlics brake
has
been replaced by an accelerator, and as we would slow down the prealcoholic
is picking up speed. Unfortunately scientists don't know the gene that
makes
Prealcohlics, but they continue to research, and explore.
Another topic I discussed with the class is a brain wave known as P3.
Doctors have found that a reduced P3 wave is found in alcoholics. P3 remains
low in alcoholics who have been abstinent for as long as ten years. P3
amplitudes predate heavy drinking and might be inherited. Scientists have
tested families and the results showed that in persons with high familial
alcoholism, P3 was reduced significantly. It is now well established that
P3
is associated with alcoholism risk.
The two distinct subtypes of alcoholism I talked about were C. Robert
Cloningers new viewpoints on inheritability of alcoholism. Most people
in
the class wrote on their evaluations that they didn't know that there were
two types of alcoholics. I'm glad I informed them on something that they
didn't know. Between the two types of alcoholism, there are many
differences, or opposites. Type I is mainly women or men, results after
the
age of twenty-five, develops anti-social behavior, drinks steadily, and
usually this results from environmental behavior. Type II is mostly
exclusively man, sons of alcoholic fathers, starts at a young age, severe
behavior occurs such as bottle throwing, door kicking, and it is strongly
genetic.
Scientists have studied families of alcoholic and non-alcoholic
backgrounds. They looked at alcoholic fathers who put their sons up for
adoption. The biological children of alcoholics had a four times higher
risk
of becoming alcoholics themselves that the children of non-alcoholics,
even
though they were separated from their alcoholic parents since birth. This
might have come out wrong when I said it in class, but when the experiment
was reversed- when the children of non-alcoholics were adopted by
alcoholics-the children had no increased risk for alcoholism, event though
they were exposed to it in the home.
In class you had mentioned treatment for alcoholism, and there is
treatment which I should have mentioned. AA or Alcoholics Anonymous is
a
counseling treatment for alcoholics. Many people do benefit from AA, and
in
fact don't have a problem anymore. Unfortunately I have known cases in
which
AA has failed. Some people resort back to the poison that almost or could
have killed them. Why people can't brake the addiction, I don't know, but
I
guess there are many addictions people cant overcome. We experience some
of
those addictions in our everyday lives.
I am glad I got to research this topic because I find it very
interesting, yet the scientific terminology is not the easiest to understand.
Even though it is very nerve racking to get up in front of my peers, I
like
the idea of hearing different points from different people in the class.
