Attention-Deficit/Hyperactivity Disorder

Apply DSM-5 criteria rather than diagnosing from a single office history or rating scale. Establish a persistent pattern of inattention and/or hyperactivity-impulsivity that is developmentally inappropriate, lasts at least 6 months, interferes with functioning or development, began before age 12 years, is present in at least 2 settings, and is not better explained by another disorder.

Obtain collateral evidence before assigning a diagnosis. In children, obtain parent and teacher reports addressing symptom frequency, impairment, academic performance, environmental context, and behavior across home and school. Nature+1NatureDevelopment of a human analogue ADHD diagnostic system for family dogs | Scientific ReportsCDCClinical Care of ADHD in Children In adults, obtain a current functional history plus evidence of childhood-onset symptoms when feasible; the Adult ADHD Self-Report Scale is useful for screening, but a positive screen requires diagnostic interview and assessment of impairment.

Screen for psychiatric comorbidity during the initial assessment and when functional decline is disproportionate to core ADHD symptoms. Adult ADHD is strongly associated with psychiatric comorbidity and functional impairment, while untreated adult ADHD is associated with substance use, accidents, suicidality, absenteeism, and impaired educational and occupational performance.

For patients with clinically significant ADHD, establish target outcomes before treatment: classroom behavior and academic productivity in children; work completion, driving safety, relationship functioning, and daily-task execution in adults. ADHD medications and nonpharmacologic approaches can reduce symptoms and associated impairment, but treatment response should be judged against the patient’s specific functional goals as well as symptom change.

Stimulant medications, including methylphenidate and amphetamine products, are the principal pharmacologic options and have the strongest short-term efficacy. In children, stimulants improve symptoms in approximately 70% and have reported short-term effect sizes of approximately 0.8 to 1.0.

Offer behavioral and psychosocial interventions as part of a treatment plan, particularly when impairment involves routines, parenting, school structure, emotional regulation, or adherence. Behavioral therapy, cognitive and parent training, dietary changes, and neurofeedback have more limited evidence for improving core symptoms than medication, while CBT-based interventions may improve symptom management and emotional regulation, often as adjuncts to medication.

At each titration or follow-up visit, compare current symptoms and function with the baseline targets and collateral ratings. Parent and teacher scales are particularly useful for measuring change in child symptoms and impairment across settings. Nature+1NatureDevelopment of a human analogue ADHD diagnostic system for family dogs | Scientific ReportsNatureAttention-deficit/hyperactivity disorder | Nature Reviews Disease Primers If symptoms improve but academic, occupational, or family impairment persists, identify whether the residual problem is insufficient medication effect, adherence, comorbidity, sleep disturbance, or a setting-specific environmental barrier before escalating dose.
