By Mayo Clinic staffSchizophrenia is a group of serious brain disorders in which reality is interpreted abnormally. Schizophrenia results in hallucinations, delusions, and disordered thinking and behavior. People with schizophrenia withdraw from the people and activities in the world around them, retreating into an inner world marked by psychosis.
Contrary to popular belief, schizophrenia isn't the same as a split personality or multiple personality. While the word "schizophrenia" does means "split-mind," it refers to a disruption of the usual balance of emotions and thinking.
Schizophrenia is a chronic condition, requiring lifelong treatment. But thanks to new medications, schizophrenia symptoms can often be successfully managed, allowing people with the condition to lead productive, enjoyable lives.
