What often characterizes the behavior of individuals with ADHD?

Individuals with ADHD, or Attention-Deficit/Hyperactivity Disorder, are often characterized by inattention and hyperactivity. This means that they may struggle to maintain focus on tasks, be easily distracted, and have difficulty organizing activities or completing assignments. In addition, hyperactivity manifests as excessive fidgeting, inability to remain seated, and a tendency to speak impulsively or disruptively. These behaviors are central to the ADHD diagnosis and significantly impact various aspects of an individual's life, including their academic performance and social relationships.

The other options do not adequately reflect the core characteristics of ADHD. A constant need for routine is more commonly associated with conditions like autism spectrum disorder, where structures play a key role in the individual’s comfort. Deliberate avoidance of social situations may be indicative of social anxiety or related disorders rather than ADHD, which often includes impulsivity and a craving for social interaction despite challenges in focus and attention. A calm demeanor regardless of situations contradicts the typical symptoms of ADHD, which usually involve high levels of energy and restlessness. Therefore, inattention and hyperactivity truly encapsulate the behavioral traits commonly observed in those with ADHD.
