Which behavior is commonly associated with ADHD in adolescents?

The behavior of constantly interrupting others is commonly associated with Attention-Deficit/Hyperactivity Disorder (ADHD) in adolescents. This behavior stems from the impulsivity and challenges with self-regulation that are characteristic of ADHD. Adolescents with ADHD often struggle to control their impulses, leading them to speak out of turn or finish others' sentences. This can disrupt conversations and social interactions, as they may have difficulty waiting for their turn to speak.

In contrast, behaviors such as pacing in one spot, excessive sleeping, or withdrawal from social interactions do not align as closely with the typical manifestations of ADHD. While pacing might be an expression of restlessness, it is more a symptom of anxiety or hyperactivity than a specific marker of ADHD. Excessive sleeping could indicate depressive symptoms or other issues, and withdrawal from social interactions is more often associated with anxiety disorders or depression rather than ADHD.
