[BMJ Journals] An internet search found over 1300 sites discussing the nature of Gollum’s "mental illness." We asked 30 randomly selected medical students if they thought Gollum had a mental illness. Schizophrenia was the most common diagnosis (25 students), followed by multiple personality disorder (three). On initial consideration schizophrenia seems a reasonable diagnosis.

Just in time for the holidays - 6 medical students (and one ‘lecturer in old age psychiatry’) produce a paper trying to diagnose Gollum’s mental health problems.
