Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) is a persistent and continuous pattern of inattention and/or hyperactivity and impulsivity, which impedes daily activities or typical development by causing difficulties in maintaining attention, executive function and working memory. Because of its impact on both children and adults, it is currently a topic of great interest and is the subject of many studies worldwide. This research addresses important aspects related to the aetiopathogenesis of the syndrome and the different treatments used to alleviate it; it also provides information about the associated morbidities and conceptual approaches that are evident in international classification systems. The research design was exploratory, retrospective and descriptive. The files of 2780 students were analysed, and only 7 teachers from the eight selected schools were interviewed. The teachers were administered the Conners questionnaire.
