Which condition is most likely indicated by persistent inattention and hyperactivity in a child over several months?

• A. Seizure disorder
• B. Autism spectrum disorder
• C. Attention-Deficit/Hyperactivity Disorder
• D. Learning disability

Answer: (C)

Persistent inattention and hyperactivity in a child for several months most strongly points to Attention-Deficit/Hyperactivity Disorder. ADHD involves patterns of inattention and/or hyperactivity-impulsivity that are more frequent and impairing than expected for the child’s age, lasting at least about six months and present in more than one setting (such as both home and school). Inattention means trouble sustaining focus, losing things, mistakes due to carelessness, and being easily distracted. Hyperactivity-impulsivity includes restlessness, fidgeting, running or climbing inappropriately, excessive talking, and difficulty waiting turns. This combination across settings interfering with functioning is what distinguishes ADHD from typical childhood behavior.

Other conditions don’t fit as well. Seizure disorders involve episodic brain activity with transient events rather than a persistent pattern of distractibility and hyperactivity. Autism spectrum disorder centers on social communication challenges and restricted interests, not a prominent, ongoing pattern of inattention and hyperactivity. A learning disability typically refers to specific academic skill difficulties with otherwise typical behavior, not a broad pattern of inattention and hyperactivity.
