Delusional Disorder: The Daily PANCE Blueprint

A 40-year-old man presents to the psychiatric clinic with a 6-month history of believing that his spouse is being unfaithful, despite no evidence to support this belief. He has no history of hallucinations, and his functioning at work and socially has not been significantly affected. Which of the following is the most likely diagnosis?

A. Schizophrenia
B. Bipolar disorder with psychotic features
C. Delusional disorder
D. Major depressive disorder with psychotic features
E. Obsessive-compulsive disorder

Answer and topic summary

The answer is C. Delusional disorder

Delusional disorder is characterized by the presence of one or more delusions for at least 1 month without the significant functional impairment or the bizarre or odd behavior seen in schizophrenia. The absence of hallucinations and the maintained functioning in daily life, despite the delusion, are key features that support a diagnosis of delusional disorder.
