There is no test that can make a schizophrenia diagnosis. People with schizophrenia usually come to the attention of a mental health professional after others see them acting strangely.
Doctors make a diagnosis through interviews with the patient, as well as with friends and family members.
Psychiatrists have the most experience with diagnosing schizophrenia. A psychiatrist or other licensed mental health professional should be involved in making a schizophrenia diagnosis whenever possible.
Often believe some things that aren't true (delusions).
May think that some people are trying to harm them (paranoia).
With treatment, they may come to understand that these experiences aren't real but are a problem with how their brains work.
Some people with schizophrenia have paranoid thinking, which causes them to have frightening thoughts, to believe that people or forces are trying to harm them, and to hear voices. Some people think that schizophrenia is the same as a "split personality" (dissociative identity disorder), but that is a different mental health problem.
Living with schizophrenia can cause many challenges. It's a difficult disease. It changes your life and the lives of your family. But you can live a full and meaningful life if:
You are willing to work at helping yourself.
You get professional help.
You have the support and understanding of your family.
