Introduction: DSM-5 defines Attention-Deficit/Hyperactivity Disorder as having a persistent pattern of hyperactivity or inattention. This affects social, emotional, cognitive, and academic performance, behavioural skills in children and adolescents. The suffering child should have more than 6 symptoms of a particular type. Due to aetiology of Dhee Dhriti and Smriti, which results in imbalance of Kala and Karma and leads to incorrect interaction of the senses with their aims (Asatmyendriyartha Samyoga), gives rise to inattention, hyperactivity and impulsivity.
