Assessment and waiting times

NHS England set up an independent ADHD taskforce to look at rising demand and long waits for assessment and to advise on a sustainable approach to ADHD services. (NHS England ADHD taskforce, established 2024) Source: NHS England, ADHD taskforce
waiting times for an adult ADHD assessment vary widely by area and can run to several years in some parts of England, as set out by the House of Commons Library.

a diagnosis of ADHD should only be made by a specialist clinician with the training and expertise to assess it, as set out in NICE guidance; a quiz or screening tool cannot diagnose ADHD.
