Mr. T wаs 42 yeаrs оld when he wаs brоught tо a psychiatrist for evaluation. He lived with his parents and four brothers. His chief complaint was that his business partner was trying to force him to quit by giving him too much work. Although he appeared outwardly calm, Mr. T complained of nervousness and restlessness. He also noted an inability to sleep at night, believing that his neighbor was making noise on purpose. Mr. T's brother corroborated that the neighbor was being quite noisy at night and did not seem to respond to requests to be quieter. The psychiatrist prescribed hypnotic and anxiolytic mediation. Three days later, the psychiatrist received a phone call from the patient's brother, who requested that Mr. T be seen emergently. Upon arriving at the psychiatrist's office, Mr. T appeared quite anxious and perplexed. He stated that the noises had grown louder and were now present throughout the day. He was also convinced that other people besides his neighbor and his business partner were trying to harm him. Mr. T's brother now reported that Mr. T's beliefs had no basis in reality.
