To the Editor: A 27-year-old male driver was admitted to our hospital because of aggression. Two months before admission, after an encounter with the police, his symptoms of aggression, physical abuse of his spouse, and suspiciousness had been exacerbated. He also had disturbed social behavior. The night before coming to the hospital, he was watching an action film, and a scene in the film made him so aggressive that his behavior became out of control, and his family brought him to Psychiatric Emergency. He had sleep problems, and he was awake all night. In the week before admission, on one occasion, he took off all his clothes and burned them all, and then spent a large amount of money buying new clothes.
