Attention-Deficit/Hyperactivity Disorder
Key Points Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition with genetic and environmental causes. Risk factors include preterm birth and maternal substance use during pregnancy. Because of the prevalence of this condition, primary care clinicians should develop the skills to diagnose and manage this condition in patients from age 4 years through adolescence. The 3 subtypes of ADHD are predominantly inattentive, predominantly hyperactive-impulsive, and combined inattentive and hyperactive-impulsive. No cardiac workup is necessary beyond conducting a thorough cardiac history before initiating stimulant medication. Stimulant medications are the most effective treatment of ADHD in school-aged children and adolescents.
