New research using brain imaging suggests that attention-deficit/hyperactivity disorder (ADHD) may not be a single, uniform condition but instead consists of at least three distinct subtypes. Traditionally, ADHD has been associated with symptoms such as inattention, distractibility, and hyperactivity—often illustrated by children who struggle to focus in class or sit still. However, clinicians and caregivers have long observed that some children display far more intense behaviors that do not fully align with these classic descriptions.

Children in this category may experience overwhelming emotional responses, including sudden outbursts, crying, or even destructive behavior when overstimulated or frustrated. These episodes can be confusing for parents and teachers, as they go beyond the typical expectations of ADHD-related impulsivity.
