Doing an assignment in Psych on the movie Fight Club (starring Edward Norton and Brad Pitt). Basically I need to diagnose the narrator (Norton) and list his symptoms.

Obviously he suffers from DID but what type...personality, fugue, amnesia, or depersonalization??? Can he suffer from more then one??

Hopefully somebody out there has seen the movie. It's an excellent movie..so if you haven't, you should check it out.
