And the mental disorder/illness is...

John Nash, Paranoid Schizophrenia.

Alex DeLarge, Antisocial Personality Disorder and probably some sort of atypical paraphilia (especially in the book).

Melvin Udall, Obsessive Compulsive Disorder.

Donnie Darko. Paranoid Schizophrenia (Although we all know better...)

Susanna Kaysen, Borderline Personality Disorder.


Lisa Rowe. She refers to herself as a "psychopath", but that is not a diagnosis. (Probably diagnosed with "Antisocial Personality Disorder", irl).

David, Post Traumatic Stress Disorder (never says this in the film but his flashbacks, nightmares, anxiety, rumination, hypervigilance etc all point to PTSD... plus this was the 50s and PTSD didn't have a name then).

Simon Lynch, Autism.

Donald Morton and Isabelle Sorenson, Asperger's Syndrome. Asperger's is a PDD (Pervasive Developmental Disorder) and can be thought as a high-functioning form of autism (for the sake of keeping this note simple).

Mr. Jones, Bipolar Disorder.

Conrad Jarrett, Major Depressive Disorder and Acute Stress Disorder (possible PTSD depending on how long ago the death of his brother was, the difference between ASD and PTSD is the duration of symptoms since the trauma).

Phoebe Lichten, Obsessive Compulsive Disorder and Tourette's Syndrome.

Maximillian Cohen, Paranoid Schizophrenia.

Elizabeth Wurtzel, Bipolar Disorder (although she has BPD traits, too).

Raymond Babbitt, Autism.

Hal Nestor, Obsessive Compulsive Disorder.

Sorry, no image available.

Teddy Daniels, (severe) PTSD and possible dissociative disorder (DD-NOS?)

Tim Warden, Autism.

Diane Downs, Histrionic Personality Disorder and Antisocial Personality Disorder.

Sybil, Dissociative Identity Disorder (formerly called "Multiple Personality Disorder")

Sarah Connor, diagnosed with schizoaffective disorder (traits of bipolar and schizophrenia) by the idiots at the Pescadero mental institution. Remember, just because someone is diagnosed with something, doesn't mean they have it.



Given John Connor's history of theft, vandalism, truancy, etc it's not unreasonable to note that a lot of shrinks might diagnosis him with Oppositional Defiance Disorder, if not outright Conduct Disorder. I can even see some over-zealous shrinks trying to diagnosis John with Reactive Attachment Disorder because of Sarah's "behavior" while he was a baby/toddler. Yes, sometimes a cigar is just a cigar.

Howard Hughes, Obsessive Compulsive Disorder.

Campbell. Never explicitly stated but he behaves like someone with Post Traumatic Stress Disorder.
