3 or more of the following symptoms—stupor, catalepsy, waxy flexibility—characterize which disorder?

• A. Hypomanic Episode
• B. Catatonic Disorder due to Another Medical Condition
• C. Manic Episode
• D. Major Depressive Episode

Answer: (B)

Catatonia is a syndrome defined by a cluster of psychomotor signs. When three or more signs appear—stupor, catalepsy, waxy flexibility—they point to a catatonic syndrome. The next step is to identify the underlying cause. If the catatonia is due to a medical condition, the appropriate diagnosis is catatonic disorder due to another medical condition. The mood disorder options describe hypomanic, manic, or depressive episodes and do not by themselves account for the specific catatonic motor findings (though catatonia can co-occur with mood disorders, the presentation here aligns with catatonia attributed to a medical condition).
