In adults, hyperactivity may also manifest as internal restlessness.AAP Guidance on ADHD Evaluation and Treatment in ChildrenThe American Academy of Pediatrics (AAP) 2019 clinical practice guideline recommends that primary care clinicians initiate an ADHD evaluation for children and adolescents aged 4–18 who present with academic or behavioural problems and symptoms of inattention, hyperactivity or impulsivity.The guideline recommends assessing children using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria, based on information from parents, teachers and other school personnel.It also calls for screening for coexisting emotional, behavioural, developmental and physical conditions.For preschool-aged children, parent training in behaviour management is recommended as a first-line approach.For school-aged children and adolescents, the AAP recommends FDA-approved medication alongside behavioural and school-based interventions. It also emphasises managing ADHD as a chronic condition, with ongoing monitoring and follow-up.
