In Cheltenham and the wider Gloucestershire area, adult and children's ADHD assessments are commissioned through Gloucestershire Health and Care NHS Foundation Trust, which oversees both adult mental health and CAMHS pathways in the county. As with much of England, waiting times are significant, and families and adults seeking an NHS assessment should realistically expect a multi-year wait from GP referral to a formal appointment, reflecting national capacity pressures rather than any failing specific to local services. GPs in Gloucestershire typically refer adults into the community mental health team initially, where ADHD may be screened alongside other presentations, sometimes delaying a dedicated assessment pathway. Some Gloucestershire patients have pursued the NHS Right to Choose route, which allows referral to alternative NHS-commissioned providers, though awareness of this option varies considerably between practices, and it is worth asking your GP directly about eligibility. During what can feel like an incredibly frustrating and uncertain wait, a qEEG brain-mapping assessment offers objective, clinically grounded data about your neurological functioning that can meaningfully support your case when you do reach the front of the queue.
