Schizophrenia, the most severe of the psychotic disorders, seems to affect about one out of every hundred people. Some researchers think that it may actually be a whole set of diseases, not just a single disease, which would explain why people with the same diagnosis can seem so different from each other. In any case, whatever schizophrenia is, it’s not “split personality,” although the two are often confused by the public; the schizophrenic mind is not split, but shattered.
