I
enjoyed learning more about how the brain and drugs interact. Since people are
driven by more impulsive parts of the brain until about 25 when it is fully
developed, it made more sense to me why phrases like “Yolo” or “full send” become
so popular with my age group since people’s brains are still developing and
they’re more prone to do those risky behaviors. Those phrases can lead to people
doing reckless things like excessive drug use or dangerous acts that could lead
to brain injuries. I currently work at Chrysalis so I know how serious those
brain injuries can be. Two of the individuals that I work with closely have
experienced traumatic brain injuries, but they affect the individuals in completely
different ways. One client is not very physically impaired, but he experiences
extreme mood swings and gets angry easily. The other client is always very
happy and does not have mood swings, but he is paralyzed on his left side, so
he is physically impaired. I also have a cousin that experienced a brain injury
about three years ago and she still experiences some migraines and trouble
concentrating but her moods have been unaffected. This just shows how
individualized each brain injury is and how they affect each person differently.
The clients I work with will have frequent doctor visits and sometimes changes
to their medication since their conditions are very fluid and shift often. I
think that it is good that treatment for brain injuries is very personalized
because sometimes that gets lost in modern medicine. I appreciate that the
treatments for brain injuries are similar to concepts in Ayurveda in that way
with individualized treatments.
I found the reading about drugs to be very interesting
because it listed the top four reasons college students use drugs as reducing
stress, getting high, social pressure, and experimentation. Some of the adults
in their 30s or 40s that I have talked to have said they experimented with
drugs in college, so I was surprised that reason was not higher on the list. I also
learned that prescription drugs are usually given orally due to the difference
in how they are processed by the body compared to other ways like injecting or
inhaling. The oral administration of drugs leads to longer effects and less of
a harsh high and come down compared to inhaling or injecting which have a quick
high and drastic come down. The combination of how different drugs affect the
body and the ways that they are administered can lead to very different
experiences making them unpredictable. The media also shows a lot of
recreational drug use but does not show the risks that can come with that use
which is dangerous because they downplay the danger or consequences that can
come with prolonged drug use or mixing drugs. Because of that, I was not very
surprised to learn that many of the hospital visits associated with drugs are
when they are used in combination with another drug, often alcohol. I had not
known that drug tolerance is a survival mechanism. It makes sense to me that
the basic needs for survival such as getting food would produce a reward
response in the brain in order to encourage that behavior. Drugs just mimic
that response in the brain. Over time that would lead to more of a desire to obtain
that reward feeling from the drugs instead of from those necessities for life which
would lead to possible negative consequences like decreased appetite or
malnutrition because they get a stronger brain response from the drug than from
those survival tasks. The extended use of drugs also leads to a decrease in the
number of dopamine receptors due to the excess of dopamine from drug use. I
found it interesting that the body has ways of regulating that imbalance of
neurotransmitters.
Learning about diseases that directly affect the brain
was interesting because many of those diseases affect other parts of the body
as well which shows the interconnectedness of the body and that when one system
gets altered it leads to problems in other systems. I recently took genetics,
so it was cool to apply some of that knowledge since some of those diseases
discussed such as Huntington’s or Tay Sachs are caused by duplications or
insertions in the organism’s genetic code. Many of the diseases that were
discussed have some genetic component which made me wonder why some people may
be diagnosed earlier than others if they have the same mutation that causes the
disease. The difference in when Tay Sachs is diagnosed could have a big impact
on the life expectancy of the person which made me wonder why that is since it’s
the same enzyme that gets affected in people with the disease. Could it be environmental
meaning that people that did not require the enzyme as much in their younger years
are less affected by the disease and have a better chance of living?
The article that discussed Ayurveda and drug discovery
was insightful because I had not realized how many of our modern medicines and
medications had come from more natural and older ayurvedic practices. I appreciate
that Ayurveda focuses on each individual and their needs since each drug can have
different effects on people. My Grandma goes to a woman who has studied
different ancient ayurvedic type medicines, so all of my Grandma’s medications
are individual to her. I’m glad to know that some of those more ancient
practices are adapting to modern-day and still being used since we have derived
so much of modern medicine from those practices it would be harmful to get rid
of them completely.
