split personality

Haha, I'm not really sure about this too, but I think split personality is one of the symptoms or presentation of the medical condition called schizophrenia. This is a psychotic condition. I remember once when I was younger I watched a drama on TV and there was this actor who was acting with split personality, sometimes he's normal and sometimes he turns into this mad person who murders. My mum told me that the person was acting as a schizophrenic person, so from that day onwards I always told myself that people with split personality would most probably be a schizophrenic person. This is just my opinion, don't take it as a fact! Do some research to see whether what I said is true or not, because I myself am not sure whether my arguments are facts.....
