The brain, which weighs only three pounds and is made up of eighty percent
water, is the key organ of our nervous system. It is divided into three
different parts: the Cerebrum, the Cerebellum, and the Medulla Oblongata. The
“gray matter” of the brain is about one-eighth inch thick and it gives the brain
its gray color. Inside the brain is the cortex, which is made up of billions of
neurons. These neurons extend into the cerebral hemisphere and it controls all
mental activity. In this report I will be discussing different disorders of the
brain and how they affect the every day life of people who may have these
disorders. (The Volume Library 900)
The first disorder that I will be
discussing is a disease called Attention Deficit Hyperactive Disorder
(A.D.H.D.). This disease has not just been recently discovered. It was first
discovered in the eighteen hundreds by a British physician where the first book
about Attention Deficit Hyperactive Disorder was written, “Fidgety Phil.” Up
until the 1960’s it was called minimal brain function. Medication is not a new
treatment either. In the 1930’s a medication called Dexedrine (d-amphetamine) or
Desoxyn (methamphetamine), now known as Ritalin, was used. (Wender, M.D. 15)
This disease is present in three to ten percent of school-aged children and
four to five percent in adults. A.D.H.D. is more common in boys than in girls.
To determine if a child has A.D.H.D., there are not set psychological or
laboratory test but the testimonies of the people who are involved in the
patients’ everyday life. However there are certain criteria that can define and
diagnose symptoms.
In many cases medication can reduce and to an extent
eliminate A.D.H.D. This is true in about seventy percent of school-aged children
who have A.D.H.D. and in about sixty percent of adults who are on the
medication. Another plus of the medication is that it is not addictive if it is
not abused. To reduce the symptoms of A.D.H.D. in adults therapy may also be
helpful. Although, the use of medication to treat A.D.H.D. can be very
controversial. (Wender, M.D. 9)
Some characteristics of school-aged children
with A.D.H.D. are problems in school like math, reading, and spelling because
twenty to thirty percent of children have learning disorders. The most common
symptom is attention difficulties, distractibility, and hyperactivity. Not all
patients of A.D.H.D are hyperactive, therefore a new diagnosis was identified:
Attention Deficit Disorder (A.D.D.). Some A.D.H.D. patients may have a lack of
memory, problems sleeping, being over talkative, and even have emotional
difficulties. (Wender, M.D. 10-26)
What causes A.D.H.D.? In Wender’s book he
relates the brain to a telephone. The telephone sends and receives electrical
impulses and the brain sends and receives chemical impulses. Theses chemicals
are called neurotransmitters. When the neurotransmitter is sent from one nerve
another one picks it up. If there are too little of a certain neurotransmitter,
the receiving nerve will not register it and it is as if the connection between
nerves has been broken. A.D.H.D. patients are deficient in creation of a certain
neurotransmitter. In some cases the amount of neurotransmitters can be increased
over time. (Wender 35)
The next disorder that I will be discussing will be
obsessive-compulsive disorder (O.C.D.). O.C.D. is defined as the anxiety caused
by an obsession a person may have (excessive washing). The only way to relieve
the anxiety is working through the obsession. The main ages that O.C.D. can
start in males are thirteen to about fifteen and in females twenty to about
twenty-four. Thirty-three to fifty percent of adults who have O.C.D. report it
starting with in childhood or the pre-stated ages. (Nathan, Gordman, and Salkind
140)
The treatment of O.C.D. is a very tedious task because it takes on
average seventeen years to completely cure. For reasons as people are secretive
or embarrassed or even in denial of having O.C.D. Another case is that it is not
easily noticed and that they might not have access to a treatment center or they
couldn’t afford the treatment. There are many ways that O.C.D. can start. One
can be just a daily pattern in someone’s life that they can become dependant on
doing. Some others are being overly worried, having parents who have O.C.D.,
also having an irregular metabolism, or an abnormal antibody response to a
virus. (Nathan, Gordman, and Salkind 142)
There was no successful
psychological or pharmacological treatment up until the 1960’s. In the 60’s
there was ongoing research on a patients surroundings, backgrounds, and
environments. This was called Exposure and Response or Blocking. It was somewhat
successful in five cases out of fifteen and through a five-year study two were
completely cured. (Nathan, Gordman, and Salkind 144)
The next disorder I
will be discussing is called Schizophrenia. Schizophrenia disrupts a person’s
ability think clearly. This is cause by the voices in their head make the person
confused. Approximately six percent of prisoners and thirty-three percent of
homeless people are affected by schizophrenia and ten percent are suicidal.
(Nathan, Gordman, and Salkind 162)
The first cases of schizophrenia are
documented to be in the late 1800’s and it was described as an illness that
begins in young adulthood and often becomes chronic. It was first studied by a
famous psychologist, B.F. Skinner, at Harvard. The cost to treat schizophrenia
is about nineteen million dollars a year. There are many characteristics of
schizophrenia. Some are delusions such as feelings of grandeur or persecution
and hallucinations hence the voices that some hear. Another is disorganized
speech or communication impairment or inappropriate emotional levels like
laughing at an inappropriate time. Some may experience a lack of energy,
motivation, or a complete loss of interest in anything. The chance of you having
or developing schizophrenia varies directly if you are related to someone who
has it than an individual that is not related to a person with schizophrenia. If
you have an identical twin that has schizophrenia your chances are increased
greatly. (Nathan, Gordman, and Salkind 163-165) (Grubin

The last disease that I will be discussing is
one called Parkinson’s disease. Parkinson’s Disease is one that does not go away
over time but it gets worse over time. There is no cure for it. It was
discovered and named after the physician that was first diagnosed with
Parkinson’s disease. He wrote the first book about it called “Essay on the
Shaking Palsy.” What happens is the neurons in the brain are slowly and
progressively injured and then they die. (Weiner, Shulman, and Lang 3-4)
Some characteristics of Parkinson’s disease are tremoring, rigidity
(stiffness in the muscles), akinesia (lack of maintaining movement), and post
instability. The indication that Parkinson’s disease is in one person and not in
another is unknown, But most likely genetic and environmental surroundings.
Genetic meaning that it runs in the family and environmental meaning something
from outside the body like toxins and drugs. (Weiner, Shulman, and Lang 32)
There are some early warning signs though. Signs like changes in facial
expressions (lack of blinking), failure to swing one arm while walking, frozen
or painful shoulder, and numbness. Along with these warning signs there are many
problems involving Parkinson’s Disease. Problems in communication, urination,
weight loss, swallowing, imparity in everyday activities, and walking and
balance problems. (Weiner, Shulman, and Lang 60)
As we have observed, the
brain is a very complex and integrated system of communication and control for
all bodily functions. Any disruption or breakdown in this system can be the
cause of a minor ailment to a major life-changing dilemma. From childhood
disorders including A.D.D. and A.D.H.D. through adulthood phobias, mental health
issues and physical diseases, the brain can be considered the omnipotent and
omniscient god of our bodies. All knowing, all-powerful.
