Schizophrenia

A serious mental disorder that affects how a person thinks, feels, and perceives reality.

What is Schizophrenia?

Schizophrenia is a serious and chronic mental disorder that affects less than 1% of the U.S. population. It is characterized by disruptions in thought processes, perceptions, emotional responsiveness, and social interactions. People with schizophrenia may seem like they have lost touch with reality, which can be frightening for them and for the people around them.

Schizophrenia is not the same as having a "split personality", a common and inaccurate stereotype. It is a distinct medical condition that can be managed with proper treatment.

People with schizophrenia are far more likely to be victims of violence than to commit it. Stigma and misrepresentation make recovery harder, education matters.

Early warning signs, before a full episode, may include withdrawing from friends and family, a drop in school or work performance, or trouble sleeping.
