An 18-year-old man is brought to the emergency department after his mother found him locked in his room stammering about a government conspiracy to brainwash him in subterranean tunnels. His mother says that he has never done this before, but 6 months ago he stopped going to classes and was subsequently suspended from college. She reports that he has become increasingly taciturn over the course of the past month. He drinks one to two beers daily and has smoked one pack of cigarettes daily for 3 years. He occasionally smokes marijuana. His father was diagnosed with schizophrenia at the age of 25 years. The patient has had no friends or social contacts other than his mother since he was suspended. He appears unkempt and aloof. On mental status examination, he is disorganized and shows poverty of speech. He says his mood is “good.” He does not hear voices and has no visual or tactile hallucinations. Toxicology screening is negative.
