Overview
Schizophrenia, from the Greek roots schizein (σχίζειν, "to split") and phrēn, phren- (φρήν, φρεν-, "mind"). It is characterised by delusions, hallucinations, disorganized speech and behaviour, which progressively leads to social and occupational dysfunction. Psychosis is a general term used to describe loss of contact with reality. Schizophrenia a kind of psychosis. But, psychosis is also exhibited in severe depression, bipolar disorder, bereavement, intoxication by illicit drugs such as cocaine, brain tumour and infections, stroke etc. Typically symptoms of schizophrenia are classified as positive and negative. Onset of symptoms typically occurs in young adulthood, [1] with approximately 0.4–0.6%[2][3] of the population affected. Many studies have identified progressive structural as well as functional brain changes. However, there is no objective laboratory test for schizophrenia and it continues to be clinically diagnosed on self-reported experiences, observed behavior.
