NHS boards have introduced minimum two-year waiting times for attention deficit hyperactivity disorder (ADHD) and autism assessments. This decision reflects the health service's struggle to manage the increased demand for these assessments.
Referrals for clinical assessments have risen sharply over the past six years. Currently, nearly 1 million people in England are on ADHD waiting lists, with the average wait already exceeding a year at 64 weeks. Additionally, about 295,000 individuals are awaiting an autism assessment.
The lengthening waiting lists are attributed to both financial strain on the NHS and a shortage of key staff. These delays can lead to significant distress for patients and families, as diagnosis is crucial for accessing clinical treatment and other forms of support, including specialist help in schools or financial support through disability benefits.
A government-commissioned review by Peter Fonagy, whose interim report was published earlier this year, noted that unmet needs, misdiagnosis, and concerns about over-medicalisation can coexist. The report concluded that more people, particularly younger individuals, are experiencing distress and seeking help, partly due to improved clinical understanding and greater recognition of previously underdiagnosed groups.
