Health Secretary Wes Streeting has launched an independent review into rising demand for mental health, ADHD, and autism services in England. The review will examine whether there is evidence of over-diagnosis and identify gaps in support. This move comes as the NHS faces increasing pressure and long waiting times.

The government is already investing in service expansion. However, NHS data shows that mental health problems and ADHD rates have risen significantly over the past two decades. Streeting believes some people on waiting lists may not need treatment. He has warned that too many are “written off” without proper care.

Wes Streeting Calls for Evidence-Based Review

Streeting emphasized the need for a clinical, evidence-based approach to the review. “We must look at this through a strictly clinical lens to get an evidence-based understanding,” he said. “That’s the only way to ensure everyone gets timely access to accurate diagnosis and effective support.”

This review is part of the government’s plan to address the rising welfare bill. The Department of Health and Social Care (DHSC) clarified that the review is separate from broader welfare reform efforts.

Mental Health and ADHD Rates Increasing

NHS figures show that the percentage of adults with mental health problems increased from 17.6% in 2007 to 22.6% in 2023-24. Rates are higher among young people and the unemployed. Additionally, 14% of adults report ADHD symptoms, up from 8% in 2007. Experts believe only about 5% have clinically diagnosable ADHD.

As of March, around four million working-age adults in England and Wales claimed disability or incapacity benefits. This is up from nearly three million in 2019, according to the Institute for Fiscal Studies.

Pressure on NHS Services and Long Waits

The DHSC acknowledged that the NHS faces increased pressure. Many people with acute needs experience long waits, overstretched services, and care inequalities. “People feel abandoned when support is needed most,” the DHSC said.

Jenny Tan, a 23-year-old student from Surrey, described waiting nearly two years for an anorexia diagnosis. She said, “I fought so hard for a diagnosis, it took years.” Tan’s case highlights the impact of long delays and over-diagnosis fears.

The review will examine how the NHS can provide earlier support and better diagnoses. Government sources aim to establish a baseline for diagnosis and define high-quality care.
