ADHD and autism diagnosis trends face scrutiny amid rising rates

A survey of general practitioners indicates that 7 in 10 doctors believe adult ADHD is being overdiagnosed. Some clinicians expressed concern regarding “superficial” assessments, warning that such processes might cause medical professionals to overlook trauma or other underlying mental health conditions.

In the UK, growing awareness has led to increased NHS waiting lists, driving patients toward private clinics where consultation costs can exceed £1,000. Some GPs noted that while NHS services may not always result in a positive diagnosis, they have rarely seen private providers reject an ADHD diagnosis. These diagnoses also impact social welfare, as they can support claims for personal independence payments.

Complementing these observations, a study published in JAMA Psychiatry by researchers from Aarhus University and the Barcelona Institute for Global Health suggests a shift in the demographic profile of those diagnosed with ADHD and autism. The research found that between 2012 and 2022, children and adolescents receiving these diagnoses increasingly resemble the general population in terms of family background and birth history, rather than possessing the distinct characteristics historically associated with these conditions.

Researchers suggest the rise in diagnoses may be driven by greater awareness, improved identification by educational services, or a shift in the clinical threshold for what warrants a diagnosis, rather than a simple increase in the prevalence of the conditions themselves.
