Attention-Deficit Hyperactivity Disorder: A Comprehensive Review

Abstract

Attention-Deficit/Hyperactivity Disorder (ADHD) is not merely a collection of symptoms but a deeply intricate neurodevelopmental condition that challenges conventional boundaries of cognition, behavior, and emotion. With its roots reaching back centuries, ADHD has evolved from moral judgments of “defective control” to a deeper understanding shaped by genetics, neurobiology, and environmental interplay. At its core, ADHD reflects disruptions in the brain’s dopamine and norepinephrine systems, leading to altered reward processing, impaired attention, and diminished executive function. Despite these advancements, ADHD remains a diagnostic puzzle. Cultural biases, gender differences, and the variability of symptoms across contexts complicate assessments. Recent breakthroughs in neuroimaging and genetic research reveal the need for holistic interventions. Beyond symptoms, ADHD is a story of resilience, adaptability, and innovation in treatment approaches. This review reimagines ADHD not as a deficit, but as a lens through which to explore human diversity in cognition and behavior. By weaving historical, biological, and therapeutic narratives, this synthesis calls for a future where ADHD management transcends reductionist approaches and embraces individualized care.
