What are the three key symptoms of ADHD?

The three key symptoms of Attention Deficit Hyperactivity Disorder (ADHD) are extreme inattention, hyperactivity, and impulsivity. These symptoms are central to the diagnosis and understanding of ADHD, distinguishing it from other psychological and behavioral conditions.

Extreme inattention refers to difficulties in maintaining focus, organizing tasks, and following through with activities, which can manifest as a tendency to make careless mistakes or become easily distracted. Hyperactivity is characterized by excessive movement and a seeming inability to stay still, often leading to disruptive behavior in settings that require quiet or concentration. Impulsivity involves acting without thinking about the consequences, which can result in challenges in self-regulation and decision-making.

These symptoms collectively impact various aspects of a person's life, including academic performance, social interactions, and daily activities, thus forming the core characteristics of ADHD. The other options describe symptoms that may be associated with different mental health conditions but do not accurately represent the primary features of ADHD.
