The main form of biological therapy for schizophrenia is drug therapy. Some drugs are more effective at reducing the positive symptoms such as delusions and hallucination than negative symptoms such as lack of motivation and social withdrawal. There are two main categories of drugs, neuroleptic drugs and atypical drugs.
Neuroleptic drugs such as Prolixin are conventional drugs that reduce psychotic symptoms but produce some of the symptoms of neurological diseases. These drugs block the activity of the neurotransmitter dopamine within 48 hours and their effect on dopamine are believed to be very important in therapy. However it takes several weeks of drug therapy before schizophrenic symptoms show substantial reduction. These drugs are

They help by only temporarily occupying the dopamine receptors and then rapidly dissociating to allow normal dopamine transmission.
Atypical drugs have several advantages over neuroleptic drugs. Firstly they have fewer side effects than neuroleptic drugs. Secondly they benefit 85% of patients with schizophrenia, compared with 65% given neuroleptic drugs. However, the atypical drugs can produce serious side effects. For example, schizophrenic patients who take clozapine have a 1-2% risk of developing agranulocytosis. This involves reduction in white blood cells, and the condition can be life threatening.

Although the use of antipsychotic drugs is crucial in the treatment of schizophrenia, many people do not experience the benefits they offer, normally due to their side effects. As a result, additional psychological treatments are used. The cognitive behavioural therapy (CBT) follows the assumption that people often have distorted beliefs which influence their behaviour in maladaptive ways. In this therapy, patients are encouraged to trace back the origins of their symptoms in order to get a better idea of how the symptoms might have developed. As well as this, they are also encouraged to evaluate the content of their delusions to consider ways in which they might test the validity of their faulty beliefs. Next the patients would be given behavioural assignments with the aim of improving their general level of functioning. The learning of maladaptive
