An NHS pilot in Sussex has so far provided ADHD assessments to more than 300 people, offering support closer to home.
Adults in Brighton & Hove, Crawley and Hastings can now access care through a neighbourhood-based scheme called ADHD Primary Care Connect, which allows patients registered at a practice in the pilot area to be referred by their GP.
The pilot has been developed by NHS organisations in Sussex as part of efforts to tackle rising demand.
Oliver Dale, chief medical officer at Sussex Partnership NHS Foundation Trust, said about 12,000 people in Sussex are currently waiting for an ADHD assessment.
