It is a pleasure and I thank you for considering me for this position. In Part A I
will discuss Schizophrenia, the causes, what part of the brain it affects, the symptoms,
medications, and therapy involved. Part B will be an interpretation of two cases I chose
with the first case being drug abuse, and the second case being Anorexia Nervosa . These
cases will be analyzed from a bio psychological perspective.
Part A: Causes and Treatment of Schizophrenia
Schizophrenia is a severe brain disease that interferes with normal mental and brain
function. The five types of Schizophrenia are: paranoid, catatonic, residual, disorganized,
and undifferentiated. This disorder triggers paranoia, delusions, and hallucinations, and
there is also a lack of motivation. If this disease is left untreated it can affect the ability
to interact with other people, to think clearly, and manage one’s emotions.
One cause of Schizophrenia (and there are many) could be, but not yet proven,
genetic. The reason for this is because if a parent or a sibling has Schizophrenia, then
another member of the family may also develop the disorder. It can also be related to
environment. Factors like an early exposure to a viral infection, stress, and childhood
trauma could also increase the risk of developing Schizophrenia. (Pinel, 2007)
Schizophrenia has many symptoms, and comes in two groups which are negative
symptoms and positive symptoms. With a person having negative symptoms of
Schizophrenia they will be as follows: a lack of motivation, inappropriate emotions, and
self neglect. When these symptoms first appear, they are often confused with depression.
With a person having positive symptoms of Schizophrenia they will be as follows:
delusions, hallucinations, and strange behavior (confusing thoughts and or speech)
Both negative and positive symptoms start to appear in adolescence or early adulthood,
and develop gradually which could sometimes go unrecognized until it is in the advanced
stage and makes it difficult to treat. There are also 5 classifications of Schizophrenia
which are based on the common symptoms a person has. The first being Paranoid
Schizophrenia which is a person who hears voices, (sometimes threatening) They may
also attack another person or an object because of fear. Disorganized Schizophrenia is the
most serious of the five classifications. This person has unpredictable behavior, they
show no facial expressions, and sometimes make up things that make no sense to others.
Catatonic schizophrenia is when a person has long periods of sitting or standing statue
like which is called catatonic stupor. This person may also have episodes of intense
activity which is called catatonic excitement. They may also hurt others or even
themselves. Undifferentiated Schizophrenics do not fit into any of the classifications.
Residual Schizophrenia is a continuation of symptoms that stay although gradually
decrease during a remission.
The neural basis does suggest an imbalance of neurotransmitters that are associated
with the development of Schizophrenia. (National Institute of Mental Health, 2008) It
seems that Dopamine is the neurotransmitter that is responsible for Schizophrenia.
Glutamate, GABA, and serotonin are also included. (Pinel, 2007) There are several
regions of the brain which do show that there is an altered level of function...
