What is Schizophrenia?
Schizophrenia is a mental disorder, which causes distorted thoughts and perceptions. Thoughts may be scrambled
or jump from subject to subject. Perceptions may be unclear outside reality, causing people to see or hear things that are
not there.
Schizophrenia is frequently a chronic illness requiring ongoing medical attention, much like hypertension or diabetes.
Those with schizophrenia can go for long periods of time without any symptoms (remission) but then they could see the return
of their symptoms (relapse).
There
are many forms of Schizophrenia. For example, a person who is incoherent but has no delusions is said to have disorganized
schizophrenia. A person who has constant feelings of being watched, followed or victimized is said to have paranoid schizophrenia.
Also someone who lacks initiative, motivation, social interest, enjoyment and emotional responsiveness is said to have undifferentiated
schizophrenia. Schizophrenia can differ in intensity, severity and frequency of both psychotic and residual symptoms from
person to person. Therefore, scientists use the word "schizophrenia” to refer to a range of illnesses from mild to severe.
Causes
There
are three main factors scientists are exploring:
Genetics- Schizophrenia is seen as a disorder that runs in families and is inherited by certain members. Also
it may be triggered by an environmental stress. Like other genetically related illnesses, schizophrenia appears when the body
undergoes hormonal and physical changes, like those that occur during puberty in the teen and young adult years.
Chemistry- Many people with schizophrenia have a chemical imbalance within their brain of the neurotransmitter
Dopamine. It has been shown that drugs that reduce schizophrenic symptoms also block dopamine receptors and those that mimic
schizophrenic symptoms increase activity at dopamine receptors.
Problems
during pregnancy and birth- some people believe that viral infection; improper nutrition during pregnancy, or birth difficulties
may increase the chances of a person developing schizophrenia.
What is Paranoid Schizophrenia?
Paranoid schizophrenia is defined in the DSM-IV as,
A type of schizophrenia in which there are:
1.
Preoccupation with one or more systematized delusions or with frequent auditory hallucinations related
to single theme.
2.
None of the following: incoherence, marked loosening associations, flat or grossly inappropriate affect,
catatonic behaviour, grossly disorganized behaviour.
It is the most common form of schizophrenia in most parts of the world. Paranoid schizophrenia may be
episodic, with partial or complete remissions, or chronic. Some of its symptoms include relatively stable, often paranoid
delusions, usually accompanied by hallucinations, particularly of the auditory varies, and perceptual disturbances. “Psychosis,
a common condition in schizophrenia, is a state of mental impairment marked by hallucinations, which are disturbances of sensory
perception, and/or delusions, which are false yet strongly held personal beliefs that result from an inability to separate
real from unreal experiences. Less obvious symptoms, such as social isolation or withdrawal, or unusual speech, thinking,
or behavior, may precede, be seen along with, or follow the psychotic symptoms.”
