Question of the Week

For August 15, 2017

A 32-year-old man presents for care accompanied by his wife. Normally quiet and mild-mannered, he paces around the room, talking rapidly and loudly about how good he feels and about his new ability to predict the future. He wants to “spread the word” about his new powers. His wife indicates that he has spent a good deal of the couple’s savings since his behavior changed approximately 6 weeks ago.

The patient has no prior psychiatric history and no known history of substance abuse, but he has a family history of depression. Routine physical examination and laboratory findings are normal.

Which one of the following diagnoses is most likely in this case?

Bipolar disorder
Delusional disorder
Depression
Brief psychotic disorder
Schizophrenia
