David Brooks in New York Times says Trump (post 7) “haunted by multiple personality disorders.”  Multiple Personality disorders, or multiple  Personality Disorders?

Brooks says that Donald Trump “is a morally untethered, spiritually vacuous man who appears haunted by multiple personality disorders” (Op-Ed, July, 29, 2016).

Brooks does not read this blog. He is not a psychiatrist. And he may not distinguish between multiple personality (a dissociative disorder) and the completely separate diagnostic category of personality disorders (paranoid, schizoid, schizotypal, antisocial, borderline, histrionic, narcissistic, avoidant, dependent, obsessive-compulsive).

Ordinarily, since most people do not think of multiple personality, I would assume that Brooks means Trump has more than one Personality Disorder.

However, Brooks’ use of the word “haunted” raises the possibility that he does mean multiple personality, since, in the popular mind, multiple personality is often thought of as being possessed.
