Autism, ADHD and mental health review: What you need to know

A 600‑page review commissioned by former health secretary Wes Streeting has concluded that while diagnoses of autism and ADHD have risen sharply among young people, the evidence does not yet support a claim of widespread over‑diagnosis, and mental‑health conditions are clearly not being over‑diagnosed. The report, authored by a panel chaired by Professor Peter Fonagy, notes that more than 4 % of children aged six to 17 have been diagnosed with autism—far above the 1‑2 % prevalence suggested by older surveys—yet data gaps prevent a definitive judgment that diagnoses are excessive. In contrast, the panel finds a genuine surge in mental‑health distress, with one in four 16‑ to 24‑year‑olds now experiencing anxiety, depression, self‑harm or eating disorders, up from one in six three decades ago, while rates of severe illnesses such as schizophrenia and bipolar disorder remain stable.

The review warns that the rapid increase in autism and ADHD labels risks turning them into barriers rather than pathways to support, especially in education, employment and social relationships. Young people diagnosed with ADHD before age 17 are four times more likely to be classified as NEET (not in education, employment or training) than their peers, and about a third of NEET 16‑ to 24‑year‑olds cite mental health or autism as a contributing factor. Experts attribute these outcomes to fragmented services and excessively long waiting times: a third of those referred to mental‑health services wait over a year, and 90 % of the 900,000 people awaiting autism or ADHD assessments have been on hold for more than three months. The report calls for a prioritised, needs‑based reassessment of waiting lists, greater use of non‑medical interventions, and higher quality, consistent assessments—particularly scrutinising private‑sector evaluations commissioned by the NHS.

Beyond the NHS, the panel highlights systemic failures across welfare, education and employment sectors, where individuals must “jump through hoops” and undergo repeated assessments to access support. It urges immediate action to streamline pathways, eliminate first‑come‑first‑served triage, and integrate holistic, non‑clinical options such as sleep hygiene and exercise, which could reduce demand for medical appointments. By addressing these gaps, policymakers can transform what the review terms a “generational opportunity” into concrete improvements for millions of young people navigating mental‑health, autism and ADHD challenges.
