ADHD persists in to adolescence and adulthood. A large majority of children drop out of treatment by the age of 15 years and won’t present to clinical services until they are in their 30s. A lot is lost during those crucial years for many and even when they recognize the need for re-engaging in treatment, they often face many hurdles: It is often difficult to establish a diagnosis of ADHD at that age, without collateral history, childhood records are often not available, and ADHD may be complicated, and often over shadowed, by other conditions such as depression, anxiety, and substance misuse. Moreover, as you know, services for young people and adults are really patchy across the UK, and non-existent in some boroughs.
