A new review using National Health Service data estimates that around 2.5 million people in the UK have attention deficit hyperactivity disorder (ADHD). However, researchers say ADHD remains underdiagnosed for many people, with adults over the age of 65 particularly at risk of being overlooked. The outlets report that the findings point to a gap between the scale of ADHD in the population and the number of diagnoses recorded, suggesting that “hundreds of thousands” of adults may be living with the condition without a formal diagnosis. The studies discussed call for improvements to recognition and support, including better pathways for adults who may not have been assessed earlier in life. Overall, the reporting agrees that ADHD diagnoses have increased, but that older adults are still less likely to come forward or be identified by healthcare services. The issue is framed as one of delayed identification and access to appropriate assessment and care rather than a change in prevalence.
