Which clinical manifestation is commonly associated with ADHD?

Impatience when waiting for a turn is commonly associated with Attention Deficit Hyperactivity Disorder (ADHD) because individuals with ADHD often struggle with self-regulation and impulse control. This can manifest as difficulty waiting for their turn in social situations or activities, leading to impulsive behaviors such as interrupting others. Patients with ADHD frequently have trouble managing their impulses and may act before fully considering the consequences, which contributes to their impatience.

In contrast, the other options highlight behaviors that are generally not characteristic of ADHD. For instance, the ability to finish tasks efficiently and consistent adherence to instructions are typically seen in individuals with better impulse control and attention regulation. High concentration on single tasks may be found in individuals with a hyperfocus on certain interests, but it is not a widespread trait in individuals with ADHD, who usually have more difficulty maintaining sustained attention over time.
