Final answer:
The symptoms of mania in youth, such as agitation and risky behavior, are often hard to distinguish from those of attention-deficit/hyperactivity disorder (ADHD).
Step-by-step explanation:
The agitation and risky behavior accompanying mania in youth are difficult to distinguish from the symptoms of attention-deficit/hyperactivity disorder (ADHD). ADHD is a neurodevelopmental disorder characterized by difficulty maintaining attention, controlling impulses, and exhibiting hyperactivity beyond what is characteristic for a person's developmental stage. While mania may present with elevated mood and high energy levels, it shares the impulsivity and hyperactivity seen in ADHD, making them challenging to differentiate without a comprehensive assessment.
