Schizophrenia is a psychiatric disease characterized by psychosis as well as negative symptoms like lack of motivation and need for pleasure, lack of emotions and judgement, disorganisation of thought and behaviour. The exact causes for schizophrenia are not known. Psychosis can occur due to alcohol, drugs, medical conditions like hypothyroidism, mania, etc. Diagnosis of both is by exclusion of physical conditions, drug abuse, etc using blood tests, imaging procedures and DSM-IV criteria.
A brain chemical, dopamine, is also thought to be involved in the causes of schizophrenia. Effective antipsychotic medications (medications which reduce psychosis) inhibit the neurons that fire this chemical while drugs that exacerbate dopamine firing are known to induce psychosis.
