What is a split personality?
There is no category or phenomenon in psychiatry called split personality. The term is commonly used in popular language to indicate a contradictory or drastically and dramatically alternating type of behavior of the”Jekyll and Hyde” type. It is often confused with the medical illness of schizophrenia because the etymology of the latter(from the Greek schizein, to split + phren, mind) suggests, misleadingly, that schizophrenia is a type of split personality. In schizophrenia, however, the splitting is within one single personality as the individual’s thoughts, feelings and emotions are seriously and confusingly disconnected from each other in a chaotic and random fashion. Schizophrenic individuals, far from having split or multiple personalities, actually have a great struggle maintaining the coherence and integrity of even a single self.
