What is schizophrenia?
Schizophrenia is a group of severe brain disorders in which people interpret reality abnormally. Schizophrenia can cause a combination of hallucinations, delusions, and disordered thinking and behavior. Contrary to some popular belief, schizophrenia isn't a split personality or multiple personality disorder. Although the word "schizophrenia" does mean "split mind," it refers to a disruption of the usual balance of emotions and thinking. Schizophrenia is a chronic condition and typically requires lifelong treatment.
What are the symptoms?
Schizophrenia symptoms are similar to other mental illnesses, and no one symptom can identify a diagnosis of schizophrenia. In men, schizophrenia symptoms typically start in the teens or 20’s. In women, schizophrenia symptoms typically begin in the 20’s or early 30’s. It is uncommon for children and those older than 45 to be diagnosed with schizophrenia.
