What is a common characteristic of attention deficit hyperactivity disorder (ADHD)?

Attention deficit hyperactivity disorder (ADHD) is primarily characterized by a persistent pattern of inattention and hyperactivity-impulsivity that interferes with functioning or development. Individuals with ADHD often exhibit difficulty maintaining attention, organizing tasks, and following through on instructions. This challenge in paying attention is not just an occasional issue; it is a consistent pattern that can affect academic performance and everyday activities.

While high levels of physical activity and impulsivity can be noted in some individuals with ADHD, these are part of the broader spectrum of symptoms associated with the disorder and are not universally present. In fact, some individuals may not display significant hyperactivity but can still have challenges with attention and impulse control. The excessive focus on tasks or inability to follow instructions, while they may occur in some cases, are not defining characteristics of ADHD. Instead, the hallmark feature remains the difficulty with sustaining attention and managing impulses effectively. This makes the first option the most representative of ADHD as a diagnostic criteria.
