Confusing administrative prevalence with population prevalence can lead to misinterpretation of health trends and needs.
when administrative prevalence is treated as though it were population prevalence, the ordinary workings of recognition and recording get mistaken for changes in the health of the population

The Review concludes that using the term 'neurodiversity' is not appropriate for describing conditions such as common mental disorders, autism, and ADHD.
The Review has to make a decision and has concluded that we will continue to describe conditions such as common mental disorders, autism and ADHD – and symptoms and traits – rather than using the term ‘neurodiversity’.

The Review emphasizes the importance of distinguishing between symptoms, distress, and disorder to avoid conflating everyday experiences with clinical conditions.
Symptoms are individual experiences or observable features: low mood, anxiety, poor concentration, inattention, disturbed sleep, irritability, impulsivity, intrusive thoughts or differences in social communication. They are extremely common in the general population, and often intertwined with everyday human experiences[41].

The Review acknowledges the limitations of current data in understanding changes in diagnostic thresholds over time.
This means that the question at the centre of public debate, whether and how far diagnostic thresholds have shifted over time, cannot presently be settled, since the data needed to settle it are not collected.

The Review used qualitative evidence from over 50 organizations and individuals to understand the lived experiences of those with mental health conditions.
Alongside the quantitative work, the Review drew on qualitative evidence and on sustained engagement with people who live with these conditions and those who work with them. Consistent themes were fragmented pathways, the repeated retelling of one’s story, long waits, variable thresholds, diagnosis as the necessary route to support, and concerns about under-recognition and misdiagnosis.

Administrative data are used to understand diagnosis, access and service activity.
For questions of diagnosis, access and service use, the Review drew on administrative data: primary care records, secondary mental health datasets, prescribing data and education data. These show how systems function, but they do not measure underlying prevalence, because a recorded diagnosis depends not only on symptoms but on impairment, help-seeking, professional recognition, referral, diagnostic thresholds, service availability, recording practice and, in some settings, the incentives created when diagnosis unlocks support.

Population surveys are the most reliable guide to whether the underlying prevalence of distress or disorder has changed in the community.
For questions of prevalence, the Review prioritised population-based studies using measures that are comparable over time, because these are not restricted to people who have sought help or received a diagnosis. The principal sources were the Adult Psychiatric Morbidity Survey (APMS), the Mental Health of Children and Young People survey (MHCYP), the UK Household Longitudinal Study (Understanding Society) and the Health Survey for England, with the Global Burden of Disease study used for international context[30-33].

The Review distinguishes between underlying prevalence, diagnosis, functional impact, and need.
The Review distinguishes between underlying prevalence, diagnosis, function and need, and clarifies these concepts in Chapter 4: (i) diagnosis, which asks whether a person meets the criteria for a defined disorder or condition; (ii) functional impact, which asks how far their difficulties affect everyday activities and participation; and (iii) need, which asks what support is required at a given moment in order to function in particular environments, and which may rise and fall over time.

The demand for assessment and support for mental health conditions has risen beyond what was anticipated.
Yet alongside this progress, the demand for assessment and support has risen to a degree that few anticipated and that current services were never designed to meet.

The government is urged to publish a cross-government mental health strategy within the year, outlining immediate actions and a long-term reform plan.
Recommendation 10: Publish a cross-government mental health strategy this year setting out how this report’s recommendations will be implemented through immediate actions in the next 12 to 24 months and a 10-year reform plan. This strategy should put improving mental health and wellbeing and improving participation at the centre of government decision-making, underpinned by transparent departmental accountability, investment and workforce requirements.

The review recommends moving from a diagnosis-dependent system to one that recognises need earlier and responds sooner.
This Review recommends moving from a system that too often requires people to wait for diagnosis before receiving help to one that recognises need earlier and responds sooner, while protecting specialist capacity for those who need it most. Diagnosis remains essential, but it should sit within a broader system organised around need rather than acting as the principal gateway to support.

The current system for ADHD and autism assessments lacks consistent oversight and quality assurance.
Independent providers now carry out more than half of all NHS-funded ADHD assessments and more than a third of autism assessments. Spending on independent-sector ADHD provision has risen by around 252% in three years, with a projected overspend of £164 million across the areas analysed alone[18]. Yet this large and fast-growing use of public money is running without consistent oversight, transparency or quality assurance – commissioners often cannot see what they are paying for (Chapter 12).
