A 27-year-old man is brought to the emergency department by his friends and his roommate. The friends state that the patient had not slept for the past 3 or 4 weeks. They have noticed that he stays up all night cleaning his apartment. He has bought new computer equipment and a digital video disc player, although his roommate claims that the patient cannot afford these kinds of items. The patient has also been bragging to his friends that he has slept with three different women in the past week, behavior very unlike his usual self, and he has been very irritable and explosive. He has been drinking a “lot of alcohol” for the past 2 weeks, which is uncharacteristic. The friends state that they have not seen the patient using drugs, and they do not think he has any medical problems or takes any prescription medication. They are not aware of any family history of medical or psychiatric disorders. They state that the patient is a graduate student in social work. On a mental status examination, the patient is noted to be alternately irritable and elated. He is wearing a bright-orange top and red slacks, and his socks are mismatched. He paces the room and refuses to sit down when asked to do so by the examiner. His speech is rapid and loud, and it is hard to interrupt him. He claims that his mood is “great,” and he is very angry with his friends for insisting that he come to the emergency department.
