Schizophrenia is a psychological disorder, thought to be caused by imbalances in brain chemistry, which involves delusions and faulty perceptions of the world. Schizophrenics often hear voices in their heads and have delusions of grandeur. It’s not uncommon for Schizophrenics to believe that they are Jesus or other prominent figures. In fact, one Schizophrenic claimed he was god’s chauffeur! There are several types of schizophrenia including disorganized, catatonic, paranoid, undifferentiated, and residual.
