Background: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders of childhood and is associated with substantial academic, behavioral, social, emotional, and health-related burdens. Contemporary care extends beyond symptom identification to include developmentally informed assessment, recognition of comorbidities, shared decision-making, and measurement-based multimodal treatment. Objective: To provide an updated, clinically oriented synthesis of current evidence on the epidemiology, neurobiology, diagnosis, differential diagnosis, comorbidities, treatment, monitoring, and long-term management of ADHD in children and adolescents. Methods: This narrative clinical review used a focused PubMed/MEDLINE search covering January 1, 2018, through August 22, 2026, supplemented by foundational publications and authoritative guidance from the American Academy of Pediatrics, National Institute for Health and Care Excellence, US Food and Drug Administration, Centers for Disease Control and Prevention, and National Institute of Mental Health. The search identified 183 records for initial consideration. Evidence was selected purposively according to pediatric relevance, methodological rigor, clinical applicability, and regulatory status. Results: ADHD is a heterogeneous disorder arising from complex genetic, neurobiological, and environmental influences. Diagnosis remains clinical and requires developmentally inappropriate symptoms, functional impairment, childhood onset, and manifestations in more than one setting, while excluding alternative explanations. Rating scales support but do not replace comprehensive clinical assessment. Comorbid learning, anxiety, depressive, oppositional, autism spectrum, tic, sleep, and substance-use disorders can substantially influence presentation and management. Behavioral parent training is recommended as first-line treatment for preschool-aged children. For most school-aged children and adolescents with clinically significant impairment, stimulants provide the strongest evidence for reducing core symptoms, whereas atomoxetine, extended-release guanfacine, extended-release clonidine, and extended-release viloxazine are appropriate alternatives for selected patients. Effective management integrates medication when indicated with psychoeducation, behavioral strategies, school-based interventions, and treatment of comorbidities. Monitoring should address symptoms, functioning, adherence, appetite, growth, sleep, blood pressure, heart rate, mood, and medication misuse or diversion. Digital interventions may offer adjunctive benefits, but current evidence does not support replacing established treatments. Conclusions: Pediatric ADHD should be managed as a chronic, developmentally evolving condition. Accurate diagnosis, individualized multimodal treatment, systematic monitoring, and planned transition to adult services can improve symptoms and functioning. Objective biomarkers, pharmacogenomics, neurostimulation, microbiome-directed therapies, and most digital interventions remain adjunctive or investigational.

Class | Typical pediatric use | Approximate coverage | Principal considerations |
|---|---|---|---|
Methylphenidate/dexmethylphenidate | Usually first stimulant trial in school-aged children; immediate- and extended-release oral or transdermal formulations | 3-12 hours, product dependent | Titrate to function and tolerability; monitor appetite, growth, sleep, pulse, blood pressure, mood, and misuse [28 -31, 36-39]. |
Amphetamine derivatives, including lisdexamfetamine | Alternative first-line stimulant; several immediate- and extended-release formulations | 4-16 hours, product dependent | Often potent; products are not milligram-for-milligram interchangeable. Apply controlled-substance safeguards [28 -31, 40-46]. |
Centanafadine extended release | An FDA approval letter was issued on July 24, 2026, for patients aged 6 years or older who weigh at least 20 kg; marketing was contingent on completion of controlled-substance scheduling, so current availability and labeling must be verified. | Once daily | Triple monoamine reuptake inhibitor and central nervous system stimulant. Labeling addresses suicidal ideation or behavior and abuse, misuse, and addiction; verify current FDA labeling and scheduling status before clinical use [47, 48]. |
Atomoxetine | Nonstimulant from age 6 years; useful with stimulant intolerance, anxiety, tics, or misuse concern | All-day after gradual onset | Dose by weight; monitor mood, blood pressure, pulse, growth, rare hepatic symptoms, and CYP2D6 interactions [33] . |
Viloxazine extended release | Nonstimulant from age 6 years | Once daily | Monitor suicidal thoughts/behavior, activation, blood pressure, pulse, sleep, and CYP1A2 interactions [35] . |
Guanfacine or clonidine extended release | Monotherapy or stimulant adjunct from age 6 years; may help hyperactivity, tics, sleep, or evening symptoms | Once daily or divided, product dependent | Sedation, hypotension, bradycardia, and rebound hypertension; taper gradually [34, 49, 50]. |
