Summary:

- An official review in England warns of potential overdiagnosis of ADHD and autism, particularly among young people.

- Review chairman Professor Peter Fonagy called for national standards to improve the accuracy and consistency of assessments.

- The review also identified a genuine increase in psychological distress and mental health problems among young people.

- Fonagy warned that anxiety and depression can intensify traits associated with ADHD and autism.

- Health Secretary Yvette Cooper welcomed the findings and called for greater emphasis on early mental health support.

- Patients reported lengthy assessment delays, including cases involving waits of more than four years.

- Around 106,000 people in England and Wales received Personal Independence Payments primarily for ADHD in July, up from 70,000 in 2024.

- Working-age sickness and disability benefits cost £58bn, with expenditure projected to reach £78bn by 2030.

- Mental health charity Mind warned that inadequate support, rather than overdiagnosis alone, remains a significant concern.

- ADHD charities raised concerns that prioritising urgent cases could leave others without treatment until their conditions deteriorate.

Why this matters: The findings raise questions about diagnostic accuracy, NHS waiting times and access to appropriate treatment. They also highlight the challenge of addressing rising mental health needs while managing increasing disability benefit expenditure.

What’s next: The Government will consider recommendations for national assessment standards and earlier intervention. Charities are calling for integrated mental health services and improvements to treatment access without requiring patients to reach crisis point.
