Crazy My Precious?

Did you ever (need to) wonder about Gollum's mental state? The Department of Mental Health Sciences, at the Royal Free and University College Medical School in London has done a formal workup of the Tolkien character. It starts off in typical medical style with "Sméagol (Gollum) is a single, 587 year old, hobbit-like male of no fixed abode. He has presented with antisocial behavior, increasing aggression, and preoccupation with the 'one ring'.'"

According to the report, Gollum displays pervasive maladaptive behavior, is obsessive though not compulsive about the ring, fulfills seven of the nine criteria for schizoid personality disorder, and is paranoid about Sauron. Being paranoid about Sauron seems healthy to me.
