Delusional Disorder changes: Which statement is true?

Delusional Disorder changes: Which statement is true?

• A. Delusions must be non-bizarre
• B. Delusions no longer must be non-bizarre
• C. Delusions must be bizarre
• D. Delusions require mood symptoms

Answer: (B)

The statement is true because DSM-5 removed the old rule that delusional disorder delusions had to be non-bizarre. Now, to meet the criteria, a person must have one or more delusions for at least a month, with no history of schizophrenia criteria being met, functioning not markedly impaired outside the delusion, and behavior not obviously bizarre or odd. Mood symptoms are not required. This change means delusions can be bizarre or non-bizarre as long as the other criteria fit, which is why the idea that delusions must be non-bizarre no longer applies.
