In Sheffield and the wider South Yorkshire area, adult ADHD assessments are commissioned through NHS South Yorkshire Integrated Care Board, with services largely delivered via Sheffield Health and Social Care NHS Foundation Trust for adults and Sheffield Children's NHS Foundation Trust for younger patients under CAMHS — though capacity across both has been under significant strain for several years. Current waiting times for a formal NHS ADHD assessment in Sheffield are realistically multi-year, reflecting a nationwide demand that has outpaced available clinical resource. Many Sheffield GPs follow a centralised referral pathway into these trust-led services, and while the NHS Right to Choose scheme theoretically allows adults to request assessment via an alternative commissioned provider, local awareness and consistent GP support for this route remains variable, meaning some patients encounter resistance or misinformation at the point of referral. For those navigating this uncertain and often exhausting wait, a qEEG brain activity screening can provide objective, clinically grounded evidence of neurological patterns associated with ADHD, offering something tangible to inform conversations with GPs and support future clinical decisions.
