Schizophrenia is a mental health disorder that affects how people perceive the world, think about themselves and others, and experience emotions. About 7-8 people out of every 1,000 individuals will develop schizophrenia, so it is not a common mental health condition like depression or anxiety. Men are slightly more likely than women to develop schizophrenia, and delusions and hallucinations typically begin between 16 and 30 years of age. Rarely, a person may develop the hallmark symptoms, hallucinations and delusions, in childhood or later in life, which can make the condition more difficult to diagnose.
People who struggle with schizophrenia are more likely to harm themselves than others, although substance abuse can increase the risk of violence toward other people or animals. It is unfortunately common for people with untreated schizophrenia to develop substance use disorders, which intensifies the symptoms of the condition as well as the risk of violence and suicide.
