LONDON — A growing number of people are seeking ADHD diagnoses without going on to pursue treatment, prompting renewed discussion among UK mental-health experts about diagnosis, care and public understanding of the condition.

Psychiatrists featured in a new Channel 4 documentary have highlighted the trend and called for further research into why some people seek a diagnosis but do not subsequently pursue treatment.

The development comes as demand for ADHD assessments continues to attract significant attention across Britain's health system.

Experts say there are several possible reasons why people may want a formal diagnosis even when they do not intend to take medication or receive other treatment. A diagnosis can help some people understand longstanding difficulties and provide an explanation for challenges affecting education, employment or relationships.

At the same time, the growing demand has intensified debate over how ADHD is diagnosed and treated, particularly as awareness of the condition has increased.

The issue is especially relevant to the NHS, where demand for neurodevelopmental assessments has placed pressure on specialist services.

Experts have stressed the need for better research to understand changing patterns of diagnosis and what patients expect from assessment services.

The debate highlights a wider challenge for UK healthcare: ensuring that growing awareness of ADHD is matched by appropriate assessment, evidence-based treatment and long-term support.

As demand continues, policymakers and clinicians face pressure to improve access while maintaining consistent standards for diagnosis.

The latest discussion could add momentum to calls for better evidence about why people seek ADHD assessments and what support they need after receiving a diagnosis.
