- ADHD is a neurodevelopmental condition of inattention, hyperactivity, impulsivity and emotional dysregulation.
- Its root is executive dysfunction: trouble starting tasks, managing time, inhibiting and sustaining attention.
- It is mostly genetic, with heritability around 70–80%.
- It usually begins in childhood and often persists; in adults hyperactivity can show as inner restlessness.
- Stimulant medication works best, often combined with CBT, coaching and psychoeducation.
Why it matters
- ADHD is common, often missed in adults and girls, and neurodivergent-affirming therapy needs to know what it is and what helps.
Key facts
- In short
- Excessive, impairing inattention, hyperactivity, impulsivity and emotional dysregulation from executive dysfunction1
- Diagnosis
- Symptoms for 6+ months in 2+ settings, several before age 12; 5 symptoms needed from age 17, 6 before1
- Causes
- Primarily genetic, heritability 70–80%; early prenatal or postnatal environmental risks1
- In adults
- An estimated 2.58% of adults have persistent ADHD and 6.76% have symptoms1
- Evidence
- Network meta-analysis of 133 trials: methylphenidate preferred in children, amphetamines in adults, short term3
- First described
- George Still, lectures to the Royal College of Physicians, 19021
In plain words
-
A self-regulation problem1
Difficulties with time management, inhibition, starting tasks and sustained attention drive the everyday problems.
-
On a spectrum1
ADHD is the extreme low end of a continuous trait of executive function and self-regulation, not a separate category.
-
Hyperfocus1
Trouble stopping an ongoing activity, even when you want to, is the flip side of poor sustained attention.
-
Three presentations1
Mainly inattentive, mainly hyperactive-impulsive, or combined; DSM-5 treats these as presentations that can change over time.
What the presentations look like in adults
-
Inattentive: losing focus4
Struggling to pay attention through meetings, lectures or long reading, or drifting to unrelated thoughts in the middle of a conversation.
-
Inattentive: organisation and deadlines4
Trouble organising work documents and belongings, scheduling time and meeting deadlines; putting off reports and long papers.
-
Inattentive: losing and forgetting4
Repeatedly misplacing documents, glasses, wallets, keys or phones, and forgetting bill payments, chores or appointments.
-
Hyperactive-impulsive: restlessness4
Leaving one's seat during a meeting or lecture, fidgeting or tapping hands or feet, or simply feeling restless.
-
Hyperactive-impulsive: talking and interrupting4
Talking a lot, blurting out answers, finishing other people's sentences, interrupting, and finding it hard to wait one's turn.
-
Accommodation: time management5
Common workplace accommodations include to-do lists, help with prioritising, meetings to clarify expectations, and timers, apps and calendars.
-
Accommodation: distraction5
A quiet workspace, noise-cancelling headphones or white noise, uninterrupted work time, and working from home when the office can't be adapted.
-
Accommodation: memory and organisation5
Written instructions, reminders, colour-coded materials, and calendars and planners.
-
Accommodation: restlessness5
Structured breaks as a physical outlet, a private workspace, or a job coach to teach and reinforce techniques.
Adult ADHD
-
It looks different1
Children climb and run; adults more often feel unable to relax, talk a lot, act impulsively or seek sensation.
-
Persistence1
About 15% of children with ADHD still meet full criteria at 25, and 50% still have some symptoms.
-
Under-diagnosed1
Most adults with ADHD remained untreated as of 2010; it is also overlooked in girls and women.
-
Diagnosis needs childhood1
Adult diagnosis generally requires symptoms since childhood, sometimes recalled with tools like the Wender Utah Rating Scale.
What the research says
-
Medication works best1
Stimulants are first-line; about 70% respond to the first stimulant tried.
-
Adults3
Amphetamines, methylphenidate, bupropion and atomoxetine beat placebo in adults; long-term effects need more research.
-
Psychological help2
CBT, psychoeducation, behavioural strategies and coaching help adults organise daily life, especially alongside medication.
-
Behavioural therapy first for some1
Behavioural therapy is first-line for mild symptoms and preschool children; parent training helps behaviour problems.
-
What lacks support1
Exercise and diet changes have no proven benefit for core symptoms, and neurofeedback is controversial.
