ADHD is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. It is one of the most common childhood disorders. There are three main subtypes - combined, predominantly inattentive, and predominantly hyperactive/impulsive. Evidence-based treatments include pharmacological interventions like stimulants and non-stimulants as well as behavioral therapies targeting things like parenting skills, classroom management, and social skills training. Exercise and physical activity are also important non-pharmacological interventions for managing ADHD symptoms. Consistency, routines, organization, and a structured environment are key to supporting children with ADHD.
