Directions: Read the following text carefully. You will then answer four questions, which ask you to respond to various aspects of the essay.
ESSAY TOPIC: Describe the mental disorder schizophrenia. Discuss the causes, symptoms, and treatment of schizophrenia. Be sure to talk about the biological bases of the disorder.
When we hear about Schizophrenia, most of us think that the person with schizophrenia has more than one personality. The truth is the victim with Schizophrenia has a mental disease
characterized by unpredictable disturbances in thinking, emotion, perception, and behavior. The word Schizophrenia is divided into two components, which are
schizo and phrenia. Schizo means "split
", which refers to personality and also focus when people are losing touch with reality. Phrenia means “ mind”
and refers to a split
mind . There are many
different factors that cause Schizophrenia. Furthermore, the symptoms may be positive or negative. We can reduce these symptoms with treatments that can
be useful to patients with this
mental disorder. Unfortunately , although
it can be treated , schizophrenia is not curable.
The exact
cause of schizophrenia is unknown, but many factors are involved in this disease. These factors include changes in the chemistry of the brain, changes in the structure of the
brain, excessive levels of dopamine, and genetic factors. Also there are other factors, which are
environmental, genetic and biochemical.
There are several environmental factors. Differential diagnosis is one
environmental factor . This factor occurs
when psychiatrists are concerned
about identifying wealthy people as schizophrenics , so they diagnose more poor people as having a
greater chance to get Schizophrenia. The second environmental factor is called downward drift. This factor
occurs when people cannot stand their job and education and as a result of this they may become of low class. The third
environmental factor happens when
people live in poor places with high
crime rates, and as a result of
this, they get stress and at the same time they get schizophrenia.
Another cause of
this disease is genetic factors. People who have relatives with schizophrenia have a 10% greater chance of developing it. Researchers
have found that identical twins stand a
50% to 85% chance of sharing the disease.
Another cause
of schizophrenia is biochemical factors. People with schizophrenia have
a chemical imbalance in their brains.
The brains of schizophrenics produce
too much of the neurotransmitter, dopamine . Neurotransmitters allow
nerve cells in the brain to send messages to each other to
make the brain function normally. The brains of schizophrenics have too much of the brain chemical called dopamine. Dopamine affects
brain processes that control movement, emotional response, and the ability to
experience enjoyment.
There are four
major subtypes of schizophrenia and
each subtype has different
symptoms. Also there are positive and
negative symptoms. The difference between these symptoms is that a positive
symptom shows clearly the attendance of
not normal behavior and
also may be controlled . On the other
hand , negative symptoms , show the absence of normal behavior. The
first subtype
is simple schizophrenia. Simple schizophrenia
has positive symptoms such as,
hallucinations or delusions . In
hallucinations , people may see, hear, touch smell objects
that do not exist.
Also, they may hear voices and
they are the only one who can
hear them. In delusions the
schizophrenic may believe in something that is not true. The second subtype of schizophrenia
is paranoid and its symptom is delusions of persecution. The person may believe that he or she
is being persecuted or harassed.
Also, they do not trust anyone.
The third subtype is hebephrenic schizophrenia. Here people may have a
disorganized behavior, disorganized speech, unusual mannerisms and facial
expressions. The fourth subtype is catatonic
schizophrenia, where symptoms are motoric immobility and
waxy flexibility. Also the people with this subtype may have strange
facial expressions, may mimic the behavior of others, and may repeat words that
others say.
There is no cure for schizophrenia. Therefore, a schizophrenic needs lots of treatment to reduce his or her symptoms. The first treatment is hospitalization and the purpose of this treatment is to evaluate and diagnose the patient, to stabilize the dangerous behavior and to familiarize the patients with treatment. There are also drugs that help schizophrenics to reduce some symptoms; these drugs are called antipsychotic drugs. Drugs are useful for reducing hallucinations and delusions. Unfortunately drugs do not reduce other symptoms .
Schizophrenia affects
10% of the population. This disease
affects the way people think, their speech, emotions, and behavior. The
victims with this disorder lose touch with
reality. Environmental factors,
genetic factors and biochemical factors are some causes of schizophrenia.
While scientists have not found the cure for this disease, they have discovered treatments to reduce the
symptoms of schizophrenia.
It was very interesting for me to learn about schizophrenia. Schizophrenia is a mental disorder characterized by unpredictable disturbances in thinking, emotion, perception, and behavior. However, poor people are more affected with this mental disorder because they have a lot of stress. Furthermore, the symptoms of schizophrenia are hallucinations, delusions, disorganized thought, disorganized behavior and difficulty expressing emotion. Also there are different subtypes of schizophrenia and these are simple schizophrenia , paranoid schizophrenia, hebephrenic schizophrenia and catatonic schizophrenia.
When I was in High School, I remember that an old man in the bus was always talking to himself and crying too. In those days I just wondered, what was wrong with him. He was always putting a bag next to him. I thought that he was mean and crazy. I think that he was just trying to be isolated from the people. Therefore, thanks to my research about schizophrenia, I have realized that this old man probably had the third subtype schizophrenia , hebephrenia, because when he was talking he had a strange facial expression and had very incoherent speech. For example, One day somebody asked him a question and he started talking like a person who did not know how to talk by saying words that were not understandable.
Learning about schizophrenia has been very helpful for me. Moreover, doing research about schizophrenia has helped to become more educated. When I was I in High School I did not learn and know about any mental disorders. As a result of this, it brought me negative thoughts about people who were schizophrenics and I did not know that they were schizophrenics. Nowadays, I feel proud of myself because I have a knowledge about schizophrenia.
