Abstract
Objective: To discuss and review the importance of early diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) in children and its proper treatment. Bibliographic review: The damage caused by the disorder includes poor development in school competence, conflicting referrals, emotional and self-esteem problems and comorbidities associated with anxiety and depression. Diagnosis depends on the use of scales and choice not only with the patient, but also with family members and teachers, according to age (4 years to 18 years) according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) of the American Psychiatric Association and the Classification of Mental and Behavioral Disorders (CID-10). Final considerations: Thanks to advances and research, there is a wide therapeutic arsenal filled with derivatives of methylphenidate or amphetamines associated with behavioral therapy, which is essential to support the decrease in drug administration in children and, consequently, reducing the adverse effects of high doses of medication.
