Attention-Deficit/Hyperactivity Disorder: Diagnosis and Multimodal Care

ADHD is persistent inattention and/or hyperactivity-impulsivity that disrupts social, academic, or developmental functioning at home and school. It affects 3–5% of school-age children, is reported more often in males (9:1), usually begins before age 7, persists through childhood, and continues into adulthood in about 30%.

The diagnostic framework requires six symptoms of inattention and six symptoms of hyperactivity/impulsivity, present for at least 6 months to a maladaptive degree with social impairment. Symptoms occur in at least two settings, such as home and school, with some present before age 7.

Before labeling ADHD, compare the pattern with normal active behavior and assess for medication adverse effects, brain trauma, conduct disorder, autism, and mood disorders. ADHD requires persistent impairment across settings; activity or inattention without that full pattern is insufficient.

Begin with nonmedical psychobehavioral treatment. Parents and teachers can shape behavior by maintaining a daily schedule, reducing distractions, setting small reachable goals, designating places for personal belongings, rewarding positive behavior, and using charts, checklists, and calm discipline.

Stimulants are first-line pharmacologic treatment. Methylphenidate is the preferred listed option; amphetamines and pemoline are also listed. By increasing dopamine and norepinephrine in the prefrontal cortex, stimulants improve attention and impulse control. One described regimen gives psychostimulants only on school days.

The cause is unknown. Reported associations include family history, trauma, mood and anxiety disorders, drug abuse, antisocial personality disorder, conduct disorder, and learning disorder. Treat these as associated conditions or possible alternatives, not as proof of ADHD.

Confirm marked social and academic impairment rather than symptoms alone. Gather observations from both parents and teachers; structured symptom-rating scales and IQ testing can help. Do not diagnose ADHD when the presentation is better explained by a general medical condition or another mental disorder.

Autism spectrum disorder is marked by persistent deficits in social communication and interaction plus restricted, repetitive behaviors, interests, or activities. Symptoms arise in early childhood, even when recognized later. This core pattern distinguishes autism from ADHD’s inattention and/or hyperactivity-impulsivity.

Limit choices and encourage healthy activities such as sports or hobbies.

Monitor for headache, tics, decreased appetite, insomnia or reduced sleep, slowed growth, and rare cardiac problems. Check blood pressure and heart rate regularly. Because medication effects and adverse-effect profiles can differ in young people, consider long-term developmental effects and teach families the expected benefits and risks.

Look for a short attention span during schoolwork, play, or eating; difficulty following instructions or staying quiet; easy distractibility; forgetfulness; losing belongings; and seeming not to listen. Consequences can include poor school performance and strained sibling relationships.

Conduct disorder: a pattern violating others’ basic rights, with three or more of the following in the past 12 months: property destruction, cruelty to animals or people, deceit or theft, or serious rule violations; one symptom must last at least 6 months. It causes clinically significant social impairment and is reserved for patients younger than 18. Oppositional defiant disorder: at least 6 months of negativistic, defiant behavior with four or more features such as temper loss, arguing, defiance, deliberate annoyance, blaming, vindictiveness, anger, or resentment.

Involve the family: parents are often the primary agents of change, especially for younger children, and family therapy can address dynamics that maintain symptoms. Coordinate with the school to implement ADHD accommodations. Family and school participation makes care extend across the same settings used to establish the diagnosis.

If stimulants do not work or adverse effects are intolerable, consider atomoxetine, a norepinephrine reuptake inhibitor, or desipramine, a tricyclic antidepressant; use tricyclics cautiously with cardiac conduction abnormalities. Combining psychobehavioral treatment with medication is better than either approach alone.

Hyperactivity and impulsivity may appear as fidgeting, overactivity, unexpectedly leaving a place and running around, excessive talking, interrupting others, disobedience, or fighting. The key is a persistent pattern that impairs social or academic function, not isolated energetic behavior.

In children, bipolar disorder may involve an extremely irritable, explosive mood, poor psychosocial functioning, decreased sleep, talkativeness, racing thoughts, and high energy. Some youths instead have severe irritability and mood swings without distinct manic episodes; this pattern led to disruptive mood dysregulation disorder.
