Abstract
Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed mental disorder in children and a small proportion retain the disorder into adulthood. The primary feature of ADHD is inattentiveness that contributes to restlessness, and it is considered a neurodevelopmental disorder characterized by a 2- to 3-year delay in cortical maturation in children. Neurophysiological studies identify functional connectivity changes in the dorsolateral prefrontal cortex, insula, and anterior cingulate cortex. The sympathomimetics that act as dopamine agonists are the mainstay in pharmacological treatment. The current article addresses the definition and manifestations of attention-deficit disorder, comorbidities in children and adults, epidemiology, neurophysiology, and pharmacological treatment strategies.
