Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neuro developmental disorder that significantly impacts academic performance in children. Characterized by symptoms of inattention, hyperactivity, and impulsivity, ADHD can lead to substantial challenges in educational settings. This paper investigates the effects of ADHD on academic achievement, examining how these symptoms disrupt learning processes and contribute to lower academic performance. Through a review of existing literature and analysis of empirical studies, the paper highlights key factors influencing academic outcomes, such as classroom behavior, task management difficulties, and the role of comorbid conditions. Additionally, it explores effective interventions, including individualized education plans (IEPs), behavioral strategies, and organizational tools, which can mitigate the academic challenges faced by children with ADHD. By providing a comprehensive overview of the relationship between ADHD and academic performance, this paper aims to inform educators, parents, and policymakers about strategies for supporting affected students and enhancing their educational experiences.
