Which feature helps differentiate pediatric bipolar disorder from ADHD?

• A. Episodic mood symptoms with distinct mood episodes
• B. Persistent attention problems across settings
• C. Grandiosity with mood shifts
• D. Decreased need for sleep without mood changes

Answer: (A)

The key idea here is that pediatric bipolar disorder is characterized by distinct mood episodes, meaning mood changes occur in clearly separated periods (such as manic or depressive episodes) with intervals of baseline mood in between. ADHD, on the other hand, features persistent attention problems, hyperactivity, and impulsivity that are chronic and occur across settings like home and school. So the presence of episodic mood symptoms that come and go distinguishes bipolar from ADHD, rather than ongoing attention problems. The other options describe either continuous attention difficulties (as in ADHD) or mood-related features that don’t alone define the episodic pattern, or an isolated symptom like decreased sleep that isn’t meaningful without a mood change.
