Psychosis

Psychosis is a serious mental disorder that involves a failure to distinguish between internal and external reality. The affected person cannot function effectively in social life.


Psychosis is a serious mental disorder characterized by defective or lost contact with reality, often with hallucinations or delusions, causing deterioration of normal social functioning.


Psychosis is a psychological disorder which is severe enough to disrupt a person's everyday life and require institutional treatment. Apart from organic causes like brain damage it has been thought by many psychologists that a psychosis is a severe form of neurosis. More recently there has been a tendency to regard biochemical factors as being important in at least some forms of psychosis. It is characterized by a lack of contact with (other people's) reality.
