What is the most common neurodevelopmental disorder in children?

Attention-deficit/hyperactivity disorder (ADHD) is indeed the most common neurodevelopmental disorder in children. It is characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning or development. ADHD affects approximately 5-10% of children globally, making it a significant concern in pediatric populations.

Understanding ADHD's prevalence is essential for awareness and early intervention strategies, as it can impact various aspects of a child's life, including academic performance, social interactions, and daily functioning. Compared to other disorders, ADHD's characteristics are widely recognized and diagnosed at a higher rate, contributing to its classification as the most common neurodevelopmental disorder.

In contrast, while conditions like autism spectrum disorder and speech delays are also prevalent, they typically do not surpass ADHD in terms of reported cases. Oppositional defiant disorder, although recognized, is less common and is often comorbid with ADHD rather than being the most frequently diagnosed on its own.
