What percentage of children aged 3-17 is estimated to be diagnosed with ADHD?

The estimate that approximately 9% of children aged 3-17 are diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) is derived from comprehensive studies and surveys conducted by health organizations, including the Centers for Disease Control and Prevention (CDC). This percentage reflects a significant prevalence of ADHD, indicating that it is one of the most commonly diagnosed neurodevelopmental disorders in children.

Some factors contributing to the increasing awareness and diagnosis of ADHD include enhanced understanding of the disorder, better diagnostic practices, and increased access to health care. The percentage of 9% suggests that ADHD is a widespread issue among the pediatric population, prompting the need for effective interventions and support systems for affected children and their families.

Considering the other options, 1%, 4%, and 15% do not accurately represent the current estimates based on a wide range of epidemiological studies, which consistently indicate that the prevalence lies closer to 9% rather than significantly lower or higher figures.
