Schizophrenia

A person diagnosed with schizophrenia may experience hallucinations (most commonly hearing voices), delusions (often bizarre or persecutory in nature), and disorganized thinking and speech. The latter may range from loss of train of thought, to sentences only loosely connected in meaning, to incoherence known as word salad in severe cases.

Social withdrawal, sloppiness of dress and hygiene, and loss of motivation and judgement are all common in schizophrenia. There is often an observable pattern of emotional difficulty, for example lack of responsiveness. Impairment in social cognition is associated with schizophrenia, as are symptoms of paranoia; social isolation commonly occurs.
In one uncommon subtype, the person may be largely mute, remain motionless in bizarre postures, or exhibit purposeless agitation


Dissociative Identity Disorder (also known as Multiple Personality Disorder)

... is a psychiatric diagnosis that describes a condition in which a person displays multiple distinct identities or personalities (known as alter egos or alters), each with its own pattern of perceiving and interacting with the environment.

"famous" examples:

main characters of "Black Swan", "A Beautiful Mind" & "The White Sound"/"Das weisse Rauschen" = schizophreniacs

Gollum (Lord of the Rings) & Marik (Yugioh DuelMonsters) = suffering from DID/MPD

That (scarily common) misconception is one of my biggest pet peeves ever.
I have a raging hate on that person, who invented this shirt, that says "I'm schizophreniac..." on the front and "Me, too" on the back.
And I back button every fanfic, that gets above explained illnesses mixed up, no matter how awesome everything else might be... well, and then I usually mail the author and tell them, they got something mixed up as nice as I can.
