Reasons for Admission

Psychotic disorders affect how people perceive reality and can create challenges in day-to-day life. Symptoms of psychotic disorders can include hallucinations and delusions. The most commonly diagnosed psychotic disorders are schizophrenia and schizoaffective disorders. People with schizophrenia may seem like they’ve lost touch with reality. The causes of schizophrenia and other psychotic disorders are unclear. Initial diagnosis of schizophrenia typically occurs between 16 and 30 years. Further information about schizophrenia and other psychotic disorder is available from the Centre for Addiction and Mental Health.
