Schizophrenia
Condition commonly mistaken for MPD (Multiple Personality Disorder). Schizophrenia like the name suggests means a split, but not a split in personality. Schizophrenia is a split in perception that causes an individual to become detached, isolated and remote from reality and from the rest of society. A person experiencing schizophrenia might see things in a way that he can only understand. He might also experience hallucinations such as hearing voices and seeing things, paranoia, feelings and thoughts of persecution and feeling like he is in another world.
