Which of the following is a common symptom of ADHD?

Impulsiveness is a hallmark symptom of ADHD. Individuals with ADHD often struggle to control their impulses, leading to hasty decisions without considering the consequences. This impulsivity can manifest in various ways such as interrupting others, difficulty waiting for turns, or engaging in risky behaviors without forethought.

Contrastingly, excessive organization, high attention span, and consistent focus are not indicative of ADHD. People with ADHD typically experience challenges with organizational skills, maintaining attention for extended periods, and focusing consistently on tasks, which highlights the significance of impulsiveness as a defining characteristic of the disorder.
