Key facts

ADHD at a glance.

What ADHD actually is, how common it is, and the shape of modern UK assessment and treatment.

  • What it is

    A neurodevelopmental condition of persistent inattention, hyperactivity and impulsivity that begins in childhood and causes real impairment across settings.

  • Presentations

    Predominantly inattentive, predominantly hyperactive/impulsive, or combined - the mix often shifts with age.

  • UK prevalence

    Around 5% of children and 2 to 3% of adults - girls and women have been historically underdiagnosed.

  • Heritability

    Strongly genetic - heritability around 70 to 80% - polygenic with modest environmental contributions.

  • Assessment

    Specialist-led per NICE NG87 - structured clinical interview, DSM-5 or ICD-11 criteria, and collateral information.

  • Treatment

    A combined package - psychoeducation, environmental changes, non-pharmacological support and, where indicated, medication.

Why this guide matters

Neurodevelopmental, lifelong, and very treatable.

ADHD is not a modern label for busy lives - it is a well-defined condition with strong evidence for effective treatment. The three points below shape everything else on this page.

  • Diagnosis is specialist-led

    GPs cannot diagnose ADHD in the UK. NICE NG87 requires a structured assessment by a specialist ADHD service, using DSM-5 or ICD-11 criteria and collateral information.

  • Treatment is a package, not a pill

    Psychoeducation, environmental changes and non-pharmacological support come first - medication is added when needed, and works best as part of the package.

  • Adult ADHD is real and common

    Around 2 to 3% of UK adults meet criteria. Many were missed as children - particularly women and girls - and diagnosis in adulthood often transforms function.

How the diagnosis is made

From first referral to a settled plan.

The steps a UK ADHD service will normally follow under NICE NG87 - so you know what to expect and why each step matters.

  1. 01

    Assessing

    Referral to a specialist ADHD service

    For under-18s that is child psychiatry or CAMHS. For adults it is an adult ADHD service. GPs cannot diagnose ADHD.

  2. 02

    Assessing

    Structured clinical assessment

    DSM-5 or ICD-11 criteria applied by a specialist - onset before age 12, impairment in two or more settings, six or more symptoms (five for adults) for at least six months.

  3. 03

    Assessing

    Standardised rating scales

    Conners, ADHD-RS and DIVA-5 in adults - completed by the patient and, where possible, a parent, partner, teacher or manager.

  4. 04

    Confirming

    Rule out differentials and comorbidity

    Anxiety, depression, trauma, PTSD, autism, learning difficulty, thyroid disease, sleep apnoea, substance misuse and hearing or vision problems are all considered.

  5. 05

    Confirming

    Supportive testing

    A QbTest (computerised attention test) can add objective data but is supportive, not diagnostic on its own.

  6. 06

    Preparing

    Baseline physical checks

    Height, weight, blood pressure, heart rate and a cardiovascular history - including any family history of sudden cardiac death - before starting medication.

  7. 07

    Preparing

    Access route - NHS or Right to Choose

    NHS ADHD waiting lists exceed two years in many trusts. Right to Choose lets adults in England pick an approved provider, often with a shorter wait.

Typical timeline: NHS routes can take two years or more; Right to Choose often much less.

Comorbidities

Rarely on its own.

Most people with ADHD have at least one other condition running alongside it. Treating both matters more than treating either alone.

  • Anxiety and depression

    The most common comorbidities in adults - often what brings someone to a GP long before ADHD is recognised.

  • Autism spectrum condition

    A substantial overlap - many patients meet criteria for both, and specialist neurodevelopmental clinics can assess them together.

  • Learning differences

    Dyslexia, dyscalculia, dyspraxia and developmental coordination disorder frequently coexist with ADHD.

  • Sleep disorders

    Delayed sleep phase, restless sleep and obstructive sleep apnoea are common - and can mimic or worsen ADHD symptoms.

  • Substance misuse

    Alcohol, cannabis and stimulant use are more common in untreated ADHD - specialist support reduces risk.

  • ODD and conduct disorder

    In children, oppositional defiant disorder and conduct disorder are frequent comorbidities requiring joint management.

  • Tic disorders

    Chronic tics and Tourette syndrome coexist with ADHD in a subset of patients - medication choice takes this into account.

  • Eating and impulse disorders

    Binge eating disorder, gambling disorder and other impulse-related conditions are more prevalent in untreated ADHD.

  • Emotional dysregulation

    Not a separate diagnosis but a core feature for many - intense feelings, quick frustration and rejection sensitivity.

Symptoms

What ADHD actually looks like.

The DSM-5 mix of inattention, hyperactivity and impulsivity - plus the features that most adults describe but the older criteria did not always name.

  • Inattention

    Difficulty sustaining attention, careless errors, forgetfulness, losing items, and being easily distracted by external stimuli.

  • Hyperactivity

    Fidgeting, an inability to stay seated, feeling driven "as if by a motor" and, in adults, restless internal energy rather than obvious movement.

  • Impulsivity

    Blurting out answers, interrupting, difficulty waiting, risky decisions and impulsive spending.

  • Executive dysfunction

    Poor planning, procrastination, time blindness, task-switching problems and difficulty finishing what you start.

  • Emotional dysregulation

    Intense feelings, quick frustration, rejection sensitivity and mood that shifts rapidly with events - a core feature for many adults.

  • Sleep disturbance

    Delayed sleep onset, restless sleep, morning grogginess and, in some, coexisting sleep apnoea or restless legs.

  • Adult presentation

    Work difficulties, unfinished projects, relationship strain, chronic lateness and coexisting anxiety or low mood - often long before a diagnosis is made.

  • Red flag - crisis or self-harm

    Suicidal thoughts, self-harm, substance dependence or a mental-health crisis need urgent NHS 111, GP or A&E contact - not a delayed ADHD pathway.

Treatment

How ADHD is treated in the UK.

Psychoeducation and environmental changes first, therapy or parent training next, then stimulants or non-stimulants when the impairment justifies it - all with regular specialist monitoring.

  • Psychoeducation

    The foundation of care - shared understanding of what ADHD is, how it shows up, and what helps. NICE recommends it for every patient.

  • Environmental modifications

    Structure, routines, external reminders, quieter workspaces and school or workplace adjustments through Access to Work.

  • Parent training programmes

    New Forest Parenting Programme for preschoolers, Incredible Years and Triple P - first-line before medication in young children.

  • CBT and ADHD coaching

    For adults - targets planning, procrastination, emotion regulation and comorbid anxiety or low mood.

  • Methylphenidate

    First-line stimulant - long-acting formulations such as Concerta XL, Xaggitin XL, Equasym XL and Medikinet XR, plus short-acting Ritalin for top-ups.

  • Lisdexamfetamine (Elvanse)

    First-line stimulant with a smoother profile - often chosen when methylphenidate is not tolerated or effective.

  • Non-stimulants

    Atomoxetine (Strattera), guanfacine (Intuniv) and off-label clonidine - useful with tics, anxiety, sleep problems or a history of substance misuse.

  • Ongoing specialist monitoring

    Six-monthly (children) or annual (adults) review of effect, cardiovascular status, growth, appetite, sleep, mood and substance use.

Where care happens

A UK ADHD service is a multidisciplinary team.

Psychiatry, psychology, ADHD coaching, occupational therapy and charity support (ADHD Foundation, ADDISS, ADHD UK) work alongside the GP. Specialist centres such as the Maudsley National ADHD Service, Great Ormond Street, Cambridge ADHD and reputable independent providers offer assessment and shared care.

Red flags

When ADHD care needs urgent attention.

Most ADHD reviews happen at planned intervals. These are the situations that should not wait for the next appointment.

  • Suicidal thoughts or self-harm

    Any active suicidal ideation, self-harm or a mental-health crisis needs same-day help through NHS 111 (option 2), a GP or A&E - do not wait for an ADHD appointment.

  • Cardiovascular concerns

    Chest pain, unexplained fainting, palpitations or a family history of sudden cardiac death under 40 needs cardiology review before starting or continuing stimulants.

  • Marked weight loss or growth faltering

    A common stimulant side effect - dose adjustment, timing changes or a planned medication break may be needed.

  • New or worsening tics

    Stimulants can unmask tics - a specialist medication review is warranted.

  • Severe insomnia

    Persistent difficulty sleeping despite good sleep hygiene needs a dose or timing review, and consideration of a non-stimulant.

  • Substance misuse

    Alcohol, cannabis, cocaine or stimulant misuse changes the risk profile - specialist input on which medication is safest is essential.

  • Pregnancy or planning pregnancy

    Medication decisions during pregnancy need a joint conversation with psychiatry and obstetrics - do not stop or start medication alone.

  • Driving safety

    DVLA must be told if ADHD affects safe driving. Untreated severe symptoms and some stimulant side effects can both matter.

  • Diversion or supply issues

    Lost, stolen or diverted controlled drugs need a specialist and pharmacy conversation - and, in 2024 to 2025, some brands have been in short supply.

Living with it

A lifelong condition, with a workable rhythm.

Four things that make the biggest day-to-day difference - external structure, protected sleep, a proper team around you, and using the rights you already have.

A quiet reminder

Adjustments are not shortcuts.

Reasonable adjustments at work, at school and in exams exist because they make a level playing field, not because they lower the bar.

  1. 01 Structure

    Externalise the plan

    Calendars, alarms, visible task lists and shared reminders take pressure off working memory - the aim is to make the environment do the remembering.

  2. 02 Rhythm

    Protect sleep

    Consistent bed and wake times, a wind-down routine and morning light exposure make the biggest single difference for most people with ADHD.

  3. 03 Support

    Build a team

    A specialist, a coach or therapist, a supportive employer or school and a good pharmacist - ADHD care is a team sport, not a solo effort.

  4. 04 Rights

    Know your entitlements

    Access to Work grants, DSA at university, reasonable adjustments at work and school EHCPs are all designed for you - use them.

Frequently asked

Everything we get asked about ADHD.

Quick answers on diagnosis, Right to Choose, medication, monitoring, driving and work.

  • What is ADHD?

    Attention deficit hyperactivity disorder is a neurodevelopmental condition of persistent inattention, hyperactivity and impulsivity that starts in childhood and causes impairment in two or more settings. In the UK it is diagnosed by a specialist using DSM-5 or ICD-11 criteria under NICE NG87.

  • How is ADHD diagnosed in adults in the UK?

    By a specialist adult ADHD service using a structured clinical assessment, DSM-5 criteria (five or more symptoms in adults), rating scales such as DIVA-5, and collateral history from a partner, parent or workplace. QbTest can support the assessment but is not diagnostic on its own.

  • What is Right to Choose?

    In England, adults referred for an NHS ADHD assessment can legally choose any approved provider that has an NHS contract, including several independent ADHD services. Waits are often much shorter than local NHS trusts, and treatment can be shared with the GP under a shared-care agreement.

  • What are the first-line medications for ADHD?

    Stimulants come first - long-acting methylphenidate (Concerta XL, Xaggitin XL, Equasym XL, Medikinet XR) or lisdexamfetamine (Elvanse). Non-stimulants such as atomoxetine or guanfacine are used when stimulants are unsuitable, ineffective or poorly tolerated.

  • Are ADHD medications safe long-term?

    They are among the best-studied medications in psychiatry. Regular monitoring covers blood pressure, heart rate, growth (in children), mood, sleep and appetite. For most people the benefits on function, safety and quality of life clearly outweigh the risks - but the decision is individual.

  • Does ADHD affect driving or work?

    It can. The DVLA must be told if ADHD or its medication affects your ability to drive safely. At work, ADHD is a disability under the Equality Act 2010 - Access to Work funding, reasonable adjustments and workplace coaching are all available.
