There is evidence that childhood experiences of abuse or trauma are risk factors for a diagnosis of schizophrenia later in life. Some researchers reported that hallucinations and other symptoms considered characteristic of schizophrenia and psychosis were at least as strongly related to neglect and childhood abuse as many other mental health problems. The researchers concluded that there is a need for staff training in asking patients about abuse, and a need to offer appropriate psychosocial treatments to those who have been neglected and abused as children.
