Typically, a person will show changes in his or her behaviors before psychosis develops. The list below includes several warning signs of psychosis.
Any one of these items by itself may not be significant, but someone with several of the items on the list should consult a mental health professional. A qualified psychologist, a psychiatrist or a trained social worker will be able to make a diagnosis and help develop a treatment plan.
If you notice these changes in behavior and they begin to intensify or do not go away, it is important to seek help. Early treatment of psychosis increases the chance of a successful recovery.
