Ack!
Schizophrenia does not equal multiple personalities.
Schizophrenia is a mental illness characterized by a splitting of the mind, emotions, and reality. It literally means "Split Mind," but this is not in the sense of having more than one personality, it is in the sense that a person's thoughts and experiences do not necessarily match their emotional responses or what is going on in the real world around them. Schizophrenics display both "Positive" and "Negative" symptoms, positive symptoms include hallucinations, delusions, ideas of reference, etc, and negative symptoms include flattened affect, lack of emotional response, etc. (Positive refers to an added trait and negative refers to a removed trait, not to the value of such traits).
Gollum displays symptoms of Dissociative Identity Disorder (formerly known as Multiple Personality Disorder). The disorder itself is actually quite controversial, as many psychologists do not believe that the human mind actually represses memories to that extent, and also because most of the cases are based in the US, there are not that many cases outside of the US.
