The police place her on an involuntary commitmentafter she states that she was instructed to kill herself byaccusatory, commanding voices. On examination the patient appearsdisheveled, with an indifferent and flat affect, and disorganizedthought processes. She answers most questions monosyllabically.When questioned about experiencing auditory hallucinations sheanswers in the affirmative, but she is unable to articulatecoherently the details of her experience. Throughout theexaminations she appears intermittently distracted by internalstimuli; when asked what her experience is in the moment, shestates: \"They are talking to me.\" The patient's family reports thatshe became increasingly withdrawn after she moved away from home toattend graduate studies at a local university. The family reportsthat her academic performance in college was above average, butsince starting university she has struggled to complete her schoolwork. Since moving, she has also become more isolative: she made nonew friends, stopped talking to her college friends, and maintainedonly sporadic contact with her family. The family was unaware ofthe patient experiencing any hallucinatory experiences. She had nopast history of drug misuse and her urine toxicology screen wasnegative, effectively ruling out a drug-induced psychosis.
