As : As dr. Bunt stated, the most obvious symptoms of schizophrenia may ebb and tide over time. Obviously, when a person has an episode of psychosis (loss of touch with reality), their symptoms have worsened. With appropriate treatment it is anticipated that the symptoms will improve. The schizophrenia may appear to be in remission, until they move toward another episode of psychosis. When a person is feeling better they might believe that they don't really have a mental health problem. They might decide to stop taking their psychiatric medications. If a person has been correctly diagnosed with paranoid schizophrenia; it is likely that their condition will worsen over time if they do not receive treatment. With each episode of psychosis the person is likely to have a reduction in their cognitive (thinking) abilities. To be diagnosed with schizophrenia they need to have symptoms for at least six months. There are other mental health conditions which may present with symptoms that are similiar to those seen in schizophrenia.

Symptoms : Symptoms can come and go, to some extent, in schizophrenia. If it is truly schizophrenia, they will come back. If they never come back, it wasn't schizophrenia. To answer your question: yes, people have been misdiagnosed in the history of mental illness.
