Question

Which of the following is not true regarding delusional disorder?

• A. Held with absolute conviction
• B. Usually false
• C. Not amenable to reasoning
• D. Occurs at early age

Answer 1

The Correct Option is D

Step 1: The question asks for the false statement, so confirm the three classic delusion characteristics and find the outlier.
Step 2: Genuine features of a delusion: it is held with unshakeable, absolute conviction; its content is usually false; and it cannot be corrected by logic or evidence (not amenable to reasoning). All three are correct.
Step 3: The remaining claim concerns onset age. Delusional disorder is a disorder of mid-life, with a mean onset near $40$ years and a wide range from about $18$ to $90$ years - it does not arise at an early age.
Step 4: Because it contributes only $1$ to $2\%$ of psychiatric inpatient admissions and presents late, the early-age statement is the incorrect one.
\[\boxed{\text{Occurs at early age}}\]
