Schizophrenia is a very baffling disease in the brain. Many people, when they hear schizophrenia, think "split personality". That information, however, is incorrect. It is not a split personality, but rather the brain is sending and recieving the wrong messages. Schizophrenics display a wide array of symptoms, but four main types of schizophrenia, differing in their specific symptoms, are recognized by some authorities.
