ADHD is a neurodevelopmental condition that affects attention, impulse control and activity levels. Symptoms include difficulty concentrating, restlessness and acting without thinking. It is usually diagnosed in childhood but many adults are diagnosed later. Assessment and support are available through the NHS — speak to a GP if you think you or your child may have ADHD. ## Who is this page for? This page is for people in the UK who want a plain-English overview of ADHD (attention deficit hyperactivity disorder), including when to seek help and what NHS care usually involves. It explains general information, not what is wrong with you personally. ## Who should skip this page? Skip this page if you need a diagnosis, a prescription, or emergency care. It cannot replace a GP, pharmacist, NHS 111 or 999. If you are in immediate danger, call 999; for urgent advice that is not life-threatening, call 111 in England, Scotland or Wales, or use your GP out-of-hours service in Northern Ireland. On this page 8 sections ## Key facts about ADHD - ADHD affects an estimated 3 to 4% of adults and about 5% of children in the UK. - Three main areas — inattention, hyperactivity, and impulsivity — though not everyone has all three. - Symptoms must be present since childhood and affect daily life in multiple settings. - Treatment can include support at school or work, talking therapies, and sometimes medication. - ADHD is not caused by bad parenting, too much screen time, or sugar — though these can affect behaviour. ## What is ADHD? Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition that affects how the brain manages attention, impulse control and activity. It is usually identified in childhood, but many people — particularly women and those with mainly inattentive symptoms — are not diagnosed until adulthood. ADHD is a recognised medical condition, not a character flaw or the result of poor discipline. ## Symptoms ADHD symptoms fall into two main groups, though many people have features of both: **Inattention:** - difficulty sustaining focus on tasks — especially boring or repetitive ones - easily distracted by external stimuli or own thoughts - forgetfulness in daily activities — keys, appointments, instructions - difficulty organising tasks and managing time - avoiding activities that need prolonged mental effort - losing things frequently **Hyperactivity and impulsivity:** - fidgeting, restlessness, difficulty sitting still - excessive talking or interrupting - acting without thinking through consequences - difficulty waiting in queues or taking turns - feeling driven by an internal motor **In adults**, hyperactivity often becomes an inner restlessness rather than obvious running and climbing. Inattention — disorganisation, procrastination, forgetfulness — may be the main problem. ## How ADHD is diagnosed Diagnosis requires specialist assessment. A GP cannot diagnose ADHD but can refer you to an NHS ADHD service (for adults) or community paediatrics or CAMHS (for children). Assessment typically includes: - detailed history of symptoms from childhood - questionnaires — sometimes completed by parents, teachers or partners - ruling out other conditions that can mimic ADHD — anxiety, depression, sleep problems, thyroid disorders, autism Symptoms must be present in **more than one setting** (for example home and school/work) and cause **significant impairment** in daily life. NHS waiting times for adult ADHD assessment vary widely by area and can be long. Some people choose private assessment — a GP may still accept a valid private diagnosis for ongoing care. ## Treatment and support There is no cure, but effective support exists: **For children:** - classroom adjustments and SEN support - parent training programmes - behavioural strategies - medication (methylphenidate and others) when appropriate — prescribed by specialists **For adults:** - psychoeducation — understanding how ADHD affects you - CBT adapted for ADHD - coaching for organisation, time management and routines - medication where appropriate - workplace adjustments under the Equality Act 2010 Treatment is tailored to the individual. Not everyone needs medication, and medication alone is rarely the whole answer. ## ADHD and mental health People with ADHD have higher rates of **anxiety**, **depression**, and sleep problems. These can overlap with ADHD symptoms or result from years of struggling undiagnosed. A comprehensive assessment considers the full picture. ## Common misconceptions - “ADHD is just naughty children” — ADHD is a neurological difference with measurable effects on daily functioning. - “Everyone is a bit ADHD nowadays” — occasional forgetfulness is normal; ADHD involves persistent, impairing symptoms since childhood. - “Sugar and screens cause ADHD” — research does not support sugar as a cause. Excessive screen time may worsen attention but does not cause ADHD. - “You grow out of it” — many adults continue to need support, though hyperactivity often becomes less visible. ## When to see a GP See a GP if you or your child have persistent attention, organisation or impulsivity problems affecting education, work or relationships. Bring examples — report cards, workplace feedback, or a partner’s observations — to help the conversation. If you are waiting for assessment, practical strategies (timers, lists, reducing distractions, breaking tasks into steps) can help while you wait. ## Getting help while waiting ## ! When to see a GP about ADHD See a GP if you or your child have persistent problems with attention, organisation, restlessness or impulsivity that affect school, work or relationships — especially if symptoms have been present since childhood. A GP cannot diagnose ADHD alone but can refer for specialist assessment. Seek urgent help if there are thoughts of self-harm — ADHD increases risk of mental health difficulties, which are treatable. ## Common questions about ADHD What are the main symptoms of ADHD? Inattention — difficulty focusing, forgetfulness, losing things, avoiding tasks needing sustained effort. Hyperactivity — fidgeting, unable to sit still, excessive talking. Impulsivity — interrupting, acting without thinking, difficulty waiting turns. Adults may mainly show inattention rather than obvious hyperactivity. Can adults have ADHD if they were not diagnosed as children? Yes. Many adults were not diagnosed in childhood, especially women and people with mainly inattentive symptoms. ADHD does not start in adulthood — a specialist looks for evidence of symptoms before age 12, though diagnosis can happen much later. How is ADHD diagnosed? There is no single blood test or scan. Diagnosis involves a detailed history — often questionnaires from the person, parents or teachers — and assessment by a specialist (psychiatrist, paediatrician or ADHD clinic). Symptoms must significantly affect daily life and not be better explained by another condition. How is ADHD treated? Treatment is individual and may combine psychoeducation, classroom or workplace adjustments, cognitive behavioural therapy (CBT), coaching for organisation, and medication (stimulants or non-stimulants) where appropriate. Treatment plans differ for children and adults. Is ADHD overdiagnosed? Views differ. Some people wait years for assessment while others question whether normal childhood behaviour is being medicalised. If you are concerned, a thorough specialist assessment is the appropriate route — not self-diagnosis from online checklists alone. Where can I get an ADHD assessment in the UK? Start by seeing a GP, who can refer you for specialist NHS assessment — an adult ADHD service for adults, or community paediatrics or CAMHS for children. NHS waiting times vary and can be long. Some people choose a private assessment with a registered psychiatrist or specialist, and under the Right to Choose scheme in England you may be able to pick an NHS-funded provider. Ask your GP what is available locally. ## Sources - [NHS — Attention deficit hyperactivity disorder (ADHD)](https://www.nhs.uk/conditions/attention-deficit-hyperactivity-disorder-adhd/) - [NICE — ADHD guideline](https://www.nice.org.uk/guidance/ng87)
