Which of the following statements about Conversion Disorder criteria is true?

• A. One or more symptoms of altered voluntary motor or sensory function
• B. Clinical findings show incompatibility between the symptom and recognized neurological or medical conditions
• C. The symptom is not better explained by another medical or mental disorder
• D. All of the above

Answer: (D)

Conversion Disorder presents with one or more symptoms of altered voluntary motor or sensory function. This means the person experiences a real change in movement or sensation that cannot be explained by a known medical disease. A hallmark of the diagnosis is that the clinical findings are incompatible with recognized neurological or medical conditions—exam results don’t fit typical patterns of organic illness, and signs may be incongruent with what an actual neuro condition would produce. Additionally, the symptom or deficit cannot be better explained by another medical or mental disorder, which helps distinguish it from other explanations for similar symptoms. When you put these pieces together, they define the diagnostic picture, and that’s why all of these statements together accurately describe the criteria. (In clinical practice, an additional criterion is that the symptoms cause distress or impairment, but the three points above capture the core diagnostic components.)
