Schizophrenia Schizophrenia is a major mental illness. In this all the components of the mind of the individual is affected, destroying his entire personality and sometimes making him unfit for life. Not only that but in schizophrenia there may be a disconnection between what the person is thinking and what he is feeling. For e.g. when we describe a sad event in our life such as the death of a close relative, our feeling becomes sad which is shown in our face and by the tone of our voice. But a patient with schizophrenia may laugh while describing sad events. This is called as incongruous affect. The patient also has strange beliefs and unusual perceptions.
Epidemiology Around 1% of the world population is affected with schizophrenia. The incidence of schizophrenia is about 1/1000. The onset of schizophrenia occurs usually later in females and often runs a more benign course, as compared to males. The male to female incidence is approximately equal.

Treatment . Most of the patients do not require hospitalisation. The usual indications for (a) For diagnostic purposes. (b) For stabilization of medication. (c) For grossly disorganized and inappropriate behaviour, including the inability to take care of basic needs such as food, clothing and shelter. (d) For patients safety because of suicidal or homicidal ideas.
Antipsychotic Medication Antipsychotic medications have revolutionized the treatment of schizophrenia. Minimum length of antipsychotic trial is 4-6 weeks in adequate dosages. If unsuccessful a drug from a different group should be tried. Patients should be maintained at the lowest possible effective dosage for 6 months to 1 year for the first episode, for 1 to 2 years for the subsequent episodes, and for indefinite period for repeated episodes or persistent symptoms. Depot preparations with long duration of action are used in patients who are irregular with their medication.
Electroconvulsive therapy Usually 6-8 ECTs are needed, given biweekly. Indications for ECT include: (i) Catatonic stupor. (ii) Uncontrolled catatonic excitement. (iii) Acute exacerbation not controlled with drugs. (iv) Severe side effects with drugs, in presence of untreated schizophrenia.
Psychosocial treatment Education of the patient and especially the family regarding the nature of illness, its course and treatment. Group therapy is particularly aimed at teaching problem solving, and communication skills. It is usually conducted in a form, which is known as ‘social skills training package’. Family therapy : Apart from education, family is also given social skills training to enhance communication and decrease family tensions
Psychosocial treatment (iv) Milieu therapy includes treatment in a living, learning or working environment ranging from inpatient psychiatric unit to day-care hospitals and halfway homes. Individual psychotherapy is usually of supportive nature. Cognitive behaviour therapy is useful. Psychosocial rehabilitation is used, usually along with milieu therapy. This includes activity therapy, to develop the work habit, training in a new vocation or retraining in a previous skill, vocational guidance, job placement, sheltered employment or self-employment, & occupational therapy.
Prognosis The course and prognosis of schizophrenia is better in the developing countries like India, than in developed countries. Almost 50% patients show complete or near complete recovery, and only 18% showed severe disability with only 9% needing institutionalisation or long term hospitalisation. We should watch for depression and suicidal ideation in recovering schizophrenics to prevent unnecessary loss of life. Depression if it occurs should be treated aggressively.
