Schizophrenia is a complex condition affecting the brain. At times how a person thinks, acts and feels may change dramatically and they may lose contact with reality. This is called psychosis. At other times, the person may feel depressed and withdraw from life. With treatment and support many people with schizophrenia manage their illness and lead regular lives. Schizophrenia doesn’t mean the person has a split personality. Their behaviour may change but this is due to the illness and not a ‘personality change’.*
