Schizophrenia is a serious brain disorder that distorts the way a person thinks, acts, expresses emotions, perceives reality and relates to others. People with schizophrenia -- the most chronic and disabling of the major mental illnesses -- often have problems functioning in society, at work and at school, and in relationships. Schizophrenia can leave its sufferer frightened and withdrawn. It is a life-long disease that cannot be cured, but usually can be controlled with proper treatment.

Contrary to popular belief, schizophrenia is not a split personality. Schizophrenia is a psychosis, a type of mental illness in which a person cannot tell what is real from what is imagined. At times, people with psychotic disorders lose touch with reality. The world may seem like a jumble of confusing thoughts, images and sounds. The behavior of people with schizophrenia may be very strange and even shocking. A sudden change in personality and behavior, which occurs when people lose touch with reality, is called a psychotic episode.
