ADHD and autism at risk of over-diagnosis, says government review

A government‑ordered review of mental‑health diagnoses in young people has warned that the United Kingdom may be shifting from a historic problem of under‑diagnosis to one of over‑diagnosis for conditions such as ADHD and autism. The study, commissioned by Labour education and health spokesperson Wes Streeting after the former health secretary claimed that youths were being “written off,” found that the number of diagnoses in the past 25 years now appears to exceed the prevalence expected in the population, especially among children and adolescents. It calls for stricter regulation of private firms that provide assessments for the NHS, including a ban on advertising, and urges a reassessment of waiting‑list priorities to ensure those with the most complex needs receive faster support.

The review links the surge in diagnoses to broader socioeconomic pressures, noting that economic uncertainty and the rise of social‑media use are driving higher rates of mental‑health problems among young people. It highlights that children diagnosed with autism or ADHD before age 17 are about four times more likely to be NEET (not in education, employment or training) between 16 and 24, underscoring the long‑term impact of inadequate post‑diagnosis support. Experts argue that labeling youths solely by their difficulties can limit their educational, occupational and relational prospects, and they stress that many young people also contend with co‑occurring conditions such as depression, which require comprehensive therapeutic and lifestyle interventions.

Personal accounts illustrate the system’s strain: the Watson family waited three years for an autism assessment for their son Atlas, who remains non‑verbal and fully dependent at age seven, and faced anxiety about his placement in a mainstream school. The review recommends that diagnosis should no longer be the sole gateway to assistance, proposing alternative non‑medical supports, school adjustments, and lifestyle aid such as sleep and anxiety management. While data show more than 4 % of children aged six to 17 are now recorded as autistic—well above the 1‑2 % prevalence suggested by research—the report cautions that older figures prevent a definitive conclusion about current over‑diagnosis. Advocacy groups, including the National Autistic Society and YoungMinds, welcomed the findings, calling for a system that better protects and empowers autistic and neurodivergent youths.
