Key facts
ADHD at a glance.
The essentials, in plain English — what it is, how common it is, and how it’s treated in the UK today.
-
What it is
A neurodevelopmental condition affecting attention, impulse control and activity — present from childhood and persisting into adulthood in many.
-
How common
Around 3–4% of UK adults; often missed — especially in women, girls and adults with predominantly inattentive symptoms.
-
Types
Inattentive, hyperactive/impulsive, or combined — the presentation can shift with age.
-
Diagnosis
Clinical — a specialist assessment covering symptoms across childhood and adulthood, with impact on function.
-
Treatment
Combination of psychoeducation, behavioural strategies and, where indicated, medication — stimulants first-line in most cases.
-
Right to Choose
In England, you can request assessment via any commissioned provider — often faster than local NHS teams.
Why this guide matters
A common condition — with a clearer path than most people expect.
ADHD is well understood and well treated. The three points below shape everything else on this page.
-
ADHD is often missed in adults
Especially in women, in people with the inattentive type, and where symptoms were masked in childhood.
-
Diagnosis is a proper assessment
Screening questionnaires are useful but not diagnostic — a specialist assessment with collateral is required.
-
You have options on the wait
In England, Right to Choose gives you access to any commissioned provider — often faster than local NHS teams.
How the diagnosis is made
From first conversation to a clear plan.
The steps a UK GP and specialist team will normally follow, in order — so you know what to expect and why.
Phase 1 · Recognising
Naming the pattern and screening
Phase 2 · Confirming
GP referral and specialist assessment
Phase 3 · Managing
Treatment plan and titration
- 01
Recognising
A pattern across settings
Symptoms present in more than one setting (school and home, or work and relationships) — not context-specific stress.
- 02
Recognising
Since childhood
Adult ADHD diagnosis requires childhood-onset symptoms — even if noticed clearly only in adulthood.
- 03
Recognising
Screening tools
ASRS-v1.1 for adults; SNAP-IV or Conners for children. A positive screen does not diagnose — it prompts assessment.
- 04
Confirming
GP conversation & referral
GP checks for other causes (thyroid, sleep, anxiety, depression) and refers for specialist ADHD assessment.
- 05
Confirming
Specialist assessment
A psychiatrist or specialist nurse takes a full history with collateral (school reports, family, partner) and applies DSM-5 or ICD-11 criteria.
- 06
Managing
A treatment plan
Psychoeducation and coaching for all; medication if impact is significant and preferred.
- 07
Managing
Titration & shared care
Stimulants started at low dose and titrated over weeks. Shared care with the GP is arranged for long-term prescribing.
Realistic timeline: NHS waits vary widely and can run to months or years; Right to Choose providers are often faster.
Symptoms
What ADHD actually looks like.
ADHD is more than distractibility. Here’s what to look for — and when to seek urgent help.
-
Difficulty sustaining attention
Losing focus mid-task, especially on the mundane — even when the task matters.
-
Easily distracted
External noise or internal thoughts frequently pull attention away.
-
Restlessness
A sense of internal restlessness, needing to move, or hyperactivity in children.
-
Impulsivity
Interrupting, blurting out, acting before thinking, difficulty waiting.
-
Time blindness
Struggling to sense time — late for things, or unable to start until the last minute.
-
Emotional dysregulation
Not a formal criterion but common — rapid, intense emotional responses that settle equally quickly.
-
Sleep problems
Delayed sleep onset, racing thoughts and difficulty waking — very commonly co-occur.
-
When to seek urgent help
Any thoughts of self-harm or suicide — see the red-flag section for support numbers.
Treatment
How ADHD is treated in the UK.
Psychoeducation and behavioural strategies for everyone; medication where it helps. Here is what each option does.
-
Psychoeducation
Understanding your ADHD is treatment — it reframes what were once seen as personal failings and unlocks better strategies.
-
Behavioural strategies & coaching
External structure (calendars, reminders, body-doubling) does the executive function work medication cannot.
-
CBT for ADHD
Adapted CBT targets procrastination, planning and self-esteem — useful with or without medication.
-
Methylphenidate
First-line stimulant for adults and children. Short- and long-acting forms; started low and titrated up.
-
Lisdexamfetamine
Long-acting stimulant, often used when methylphenidate is not enough or not tolerated.
-
Atomoxetine
Non-stimulant option — useful when stimulants are unsuitable or cause side effects.
-
Guanfacine (children)
A non-stimulant for children when stimulants are not appropriate.
-
Treat coexisting conditions
Anxiety, depression, sleep problems and substance use often coexist — treating them alongside ADHD improves outcomes.

Red flags
When to reach out — and where.
These are the moments where ADHD or its treatment needs prompt attention. If you are in crisis right now, the last item on this list has the numbers to call.
-
Thoughts of self-harm
Any thoughts of harming yourself — please reach out. See the numbers at the bottom of this list.
-
Suicidal thoughts or planning
Especially with intent — urgent help is available. See the numbers below.
-
Chest pain or palpitations on stimulants
Contact your prescribing team — a review is needed. Cardiac assessment before starting is standard.
-
Very high blood pressure
Stimulants raise BP modestly — monitor and treat if elevated.
-
Substance misuse
ADHD raises the risk. Ask for help — specialist support is available and does not preclude ADHD treatment.
-
Severe mood swings or psychosis
New or worsening on stimulants — contact your prescribing team promptly.
-
Pregnancy planning
Discuss medication with your team — risk/benefit is individual and treatment can often continue.
-
Sudden weight loss in children
A common stimulant side effect — review dose, timing and diet.

Living with it
Manageable, with the right scaffolding.
Four things that make the biggest difference day to day — systems, sleep, movement and reasonable adjustments at work.
A quiet reminder
Structure beats effort, every time.
Systems you can lean on — kept up for months — do more than a heroic week of willpower that doesn’t last.
- 01 Systems
External structure beats willpower
Calendars, timers, body-doubling and reminders offload executive function. Do not try to remember — build systems.
- 02 Sleep
Sleep is treatment
ADHD and sleep problems reinforce each other. Fixing sleep often improves attention almost as much as medication.
- 03 Movement
Exercise measurably helps
Regular activity improves focus, mood and sleep. Not a substitute for treatment — but a real part of it.
- 04 Work
Reasonable adjustments
ADHD is covered by the Equality Act. Written instructions, quiet space and flexible timing are all reasonable requests.
Frequently asked
Everything we get asked about ADHD.
Quick answers on diagnosis, Right to Choose, medication and safety.
-
What is ADHD?
A neurodevelopmental condition affecting attention, impulse control and activity — present from childhood and often continuing into adulthood.
-
How is it diagnosed?
By specialist assessment — a psychiatrist or specialist nurse taking a full history (including childhood evidence and current impact), applying DSM-5 or ICD-11 criteria. Screening questionnaires are useful but do not diagnose.
-
How long is the NHS wait?
Waits vary widely, sometimes years. In England, you can request assessment via a Right to Choose provider, which is often much faster.
-
What is Right to Choose?
In England, you can ask your GP to refer you to any provider commissioned by NHS England for ADHD assessment — not just the local team. Waits and pathways vary between providers.
-
Are stimulants addictive?
When prescribed for ADHD and used as directed, stimulants do not cause craving or dependence in the way they can when misused. In fact, treatment reduces substance-misuse risk.
-
Do I need medication?
Not always. Psychoeducation, coaching and behavioural strategies help many — medication is added when impact is significant or non-medication approaches are not enough.
-
What is titration?
The gradual dose increase after starting a stimulant — to find the lowest effective dose with minimal side effects. Usually takes 4–8 weeks.
-
Do I need an ECG before starting?
Blood pressure and pulse are checked, and an ECG if there are cardiac risk factors, personal or family cardiac history. Not routine for everyone.
-
Can I still drink alcohol?
In moderation, yes. Alcohol interacts unpredictably with stimulants — and both can worsen sleep. If you drink, keep it moderate and consistent.
-
When should I contact my team urgently?
Chest pain, palpitations, very high blood pressure, severe mood change, or any thoughts of self-harm — contact your prescribing team promptly, or emergency services if urgent.
