ADHD Is Not a Myth: Why the Way We Discuss It Matters
ADHD, evidence and lived experience
Following Channel 4’s documentary The Great ADHD Myth?, it is important to distinguish legitimate questions about assessment and treatment from language that risks invalidating a recognised condition and the people whose lives are affected by it.
On 18 August 2026, Channel 4 broadcast The Great ADHD Myth?, a documentary examining whether ADHD is a genuine neurodevelopmental condition or a social construct.
Questions about increases in referrals, assessment quality, access to support and the appropriate use of medication are legitimate. Services should be accountable, assessments should be comprehensive and treatment should always be based on individual clinical need.
However, questioning the quality of some services is not the same as questioning whether ADHD itself is real.
For people living with ADHD—and the families, partners and professionals supporting them—the condition is not an abstract debate. Its effects may be felt across education, employment, finances, relationships, parenting, emotional wellbeing and personal safety.
ADHD is a recognised neurodevelopmental condition
ADHD is recognised within established international diagnostic systems and by organisations including the NHS, NICE and the Royal College of Psychiatrists. It is characterised by persistent difficulties involving attention regulation, hyperactivity and/or impulsivity that begin during development and cause meaningful impairment.
Professional response
The Royal College of Psychiatrists responds
Following the documentary, the Royal College of Psychiatrists warned that the language used when discussing neurodevelopmental conditions can contribute to harmful stigma and discourage people from seeking assessment, treatment and support.
The College stated that research suggests approximately 3–5% of the population have ADHD and that the condition remains under-recognised, under-diagnosed and under-treated in the UK.
It acknowledged that the rise in ADHD referrals and diagnoses needs to be understood. Possible explanations may include improved public awareness, unmet historical need, differences in access and, in some cases, poor-quality or inaccurate assessment.
Crucially, the College distinguished scrutiny of assessment quality from invalidation of ADHD itself. Its position was clear: dismissing the condition does a disservice both to people living with ADHD and to the professionals involved in their care.
We can question services without invalidating ADHD
Responsible discussion about ADHD should be possible. It is appropriate to ask whether assessments are sufficiently comprehensive, whether alternative explanations have been considered and whether people receive suitable support after diagnosis.
It is also appropriate to discuss the benefits, limitations and possible adverse effects of medication. Medication is not right for everyone and should not be prescribed without proper assessment, baseline checks, monitoring and review.
Yet none of these questions demonstrate that ADHD is a myth.
Questions we should ask
- Are assessments comprehensive and evidence-informed?
- Are developmental history and functional impact considered?
- Have alternative and coexisting conditions been explored?
- Is medication prescribed and monitored safely?
- Can people access psychological and practical support?
- Are schools and workplaces making appropriate adjustments?
Conclusions we should avoid
- Everyone experiences ADHD in the same way.
- A questionnaire alone can confirm a diagnosis.
- Every person diagnosed needs medication.
- Lifestyle changes make ADHD disappear.
- Successful people cannot have ADHD.
- Concerns about some services mean the condition is not real.
What does ADHD actually look like in people’s lives?
ADHD is sometimes reduced to being distracted, energetic or forgetful. These experiences occur within the general population, but an ADHD diagnosis is not based on the occasional presence of common traits.
Clinicians consider whether there is a persistent pattern of symptoms, whether it began during development, whether it is present across important areas of life and whether it causes clinically meaningful impairment.
For some people, ADHD may contribute to:
- Repeatedly missing deadlines despite understanding their importance.
- Difficulty starting, organising or completing everyday tasks.
- Losing employment or struggling to work consistently at their ability level.
- Underachievement or exclusion within education.
- Impulsive financial, personal or occupational decisions.
- Conflict within relationships due to forgetfulness, interruption or emotional reactions.
- Difficulty managing appointments, correspondence, bills and household responsibilities.
- Sleep difficulties, exhaustion and repeated periods of overwhelm.
- Low self-esteem following years of being described as lazy, careless or difficult.
- Increased vulnerability where anxiety, depression, trauma or substance misuse is also present.
Not everyone with ADHD will experience all these difficulties, and their severity will vary. Some people develop effective coping strategies or receive support that reduces the visible impact.
Outward achievement does not necessarily show how much effort, anxiety, external support or last-minute urgency was required to maintain it.
Does the absence of a diagnostic brain scan mean ADHD is not real?
There is currently no single brain scan, blood test or genetic test that can diagnose ADHD in an individual. This is why ADHD diagnosis is based on comprehensive clinical assessment rather than one biological test.
The absence of an individual diagnostic biomarker does not establish that a condition is fictional. Many recognised health conditions are identified through clinical history, patterns of symptoms, functional impact and the exclusion of alternative explanations.
Research has identified genetic and neurobiological associations with ADHD at a group level. However, these findings are not sufficiently specific to diagnose one individual, and people with ADHD are not biologically identical.
A clinical diagnosis is not “just a questionnaire”
Rating scales can contribute useful information, but they should not be used alone to diagnose ADHD. A high-quality assessment requires clinical judgement, developmental and psychiatric history, evidence of functional impairment, consideration of symptoms across settings and exploration of alternative or coexisting conditions.
What should a high-quality ADHD assessment include?
The Royal College of Psychiatrists highlighted concerns about brief assessments that may not capture a person’s wider circumstances. Lycali agrees that an ADHD diagnosis should never be made from a short questionnaire or isolated conversation.
Assessment should consider:
- The person’s current concerns and reasons for requesting assessment.
- Developmental history, including evidence of childhood symptoms.
- Experiences across education, employment, home life and relationships.
- The frequency, persistence and severity of symptoms.
- The extent of functional impairment.
- Information from a parent, partner or other informant where available and appropriate.
- Relevant educational or clinical records where available.
- Physical health, mental health and substance use.
- Possible differential diagnoses and coexisting conditions.
- Whether another explanation better accounts for the person’s presentation.
A robust assessment must remain open to different conclusions. It may confirm ADHD, identify another condition, recognise overlapping needs or conclude that the diagnostic threshold has not been met.
Responsible assessment is not about providing the diagnosis somebody expects. It is about reaching the most clinically defensible conclusion and explaining it clearly.
National clinical guidance
What does NICE recommend?
NICE guideline NG87 states that ADHD should only be diagnosed by an appropriately qualified healthcare professional with relevant training and expertise.
Diagnosis should follow a full clinical and psychosocial assessment, a developmental and psychiatric history, and consideration of the person’s mental state and circumstances.
NICE is also clear that diagnosis should not be made solely from rating scales or observational data. Symptoms must be associated with meaningful impairment and occur across two or more important settings.
ADHD treatment is not simply about medication
Public discussion can sometimes imply that diagnosis automatically leads to medication. It does not.
Treatment should be personalised according to the person’s age, needs, preferences, circumstances, level of impairment, physical health and coexisting conditions.
Lifestyle factors such as sleep, physical activity, nutrition, routine and reduced environmental distraction may support general wellbeing and symptom management. These approaches can be valuable, but improvement following lifestyle changes does not prove that ADHD was never present.
Medication may be beneficial for some people and unsuitable or unwanted for others. Where it is prescribed, it should be carefully titrated and monitored. Medication should not be started, stopped or changed solely because of a television programme; concerns should be discussed with the person’s prescriber.
The environment matters—but that does not make ADHD unreal
Modern environments may place significant demands on attention, organisation, emotional regulation and self-management. Large classrooms, rigid behaviour policies, constant digital stimulation, insecure employment and complex administrative systems may intensify difficulties.
Recognising the influence of the environment is important. Schools, employers and public services should consider how their systems may disadvantage people with different neurodevelopmental needs.
But environmental influence and neurodevelopmental difference are not mutually exclusive. A person’s difficulties can be genuine while also becoming more or less disabling depending on the support, expectations and environment around them.
The fact that the right environment can reduce impairment does not mean that the underlying need was imaginary.
Why “myth” is not a harmless word
Media organisations have an important role in scrutinising healthcare. However, framing ADHD as a possible myth risks extending the question beyond service quality and into the legitimacy of the people who live with the condition.
For someone who has spent years being told to try harder, become more organised or stop making excuses, this framing may reinforce shame rather than encourage informed discussion.
It may also influence the way parents, teachers, employers and partners respond. A child’s distress may be treated as poor behaviour. An adult’s requested adjustments may be dismissed. Someone already uncertain about seeking help may decide that their difficulties will not be taken seriously.
Debate should improve care—not deepen stigma
We should be able to challenge poor assessment, unsafe prescribing, long waiting lists and inadequate post-diagnostic support without portraying ADHD itself as fashionable, invented or unreal.
The emotional consequences can be serious
ADHD does not inevitably result in mental-health difficulties. However, years of unsupported impairment, repeated criticism, exclusion, relationship breakdown or occupational instability can contribute to significant psychological distress.
Some people with ADHD also experience anxiety, depression, trauma, self-harm, substance misuse or suicidal thoughts. These difficulties require individual assessment and should never be dismissed as attention-seeking, a personality flaw or an inevitable feature of ADHD.
Responsible ADHD care must therefore look beyond symptoms and consider the person’s emotional wellbeing, relationships, daily functioning, safety and wider psychosocial circumstances.

Evidence, context and the whole person
Lycali’s approach to ADHD
At Lycali, we believe that ADHD assessment should be clinically robust, evidence-informed and open to all appropriate outcomes.
Assessment should not just identify whether somebody reports ADHD traits. It should explore development, context, functional impact, strengths, risks, mental health, differential diagnoses and coexisting needs.
We also believe that diagnosis should not be the end of the pathway. People may require psychoeducation, environmental adjustments, practical strategies, psychosocial assessment, psychological intervention or medication management where clinically appropriate.
The aim should not be to fit people into a label or to dismiss their experiences. It should be to understand what is happening, reach a defensible clinical conclusion and identify the combination of support most likely to improve the person’s quality of life.
ADHD is real and good care still matters
It is possible to hold two important positions at the same time.
ADHD is a real and recognised neurodevelopmental condition that can have a profound effect on people’s lives. At the same time, assessments must be thorough, diagnoses must be clinically justified and treatment must be personalised and properly monitored.
Improving standards does not require us to invalidate ADHD. In fact, rigorous assessment and individualised care are some of the strongest protections against both misdiagnosis and missed diagnosis.
The most constructive question is not whether ADHD is a myth. It is whether people experiencing significant difficulties can access accurate assessment, appropriate support and respectful, evidence-informed care.
