There is no central record of the number of individuals diagnosed with ADHD by Health and Care Jersey (HCJ), and no functionality to report this from electronic record systems. Therefore, Article 3 of the Freedom of Information (Jersey) Law 2011 applies. 

As of 04 November 2025, there are 383 clients on the Adult ADHD service caseload.  These figures will not include those who have received care and are now closed to the service (historic input), or those who have been diagnosed privately or in other jurisdictions and are not yet known / not open to the service, including those who have arrived in Jersey with a diagnosis who have never been referred for care.

Waiting list data for HCJ’s Adult ADHD Service is included in the Quality and Performance Report, published to Government of Jersey​ and within HCJ’s Advisory Board papers:

As this information is available elsewhere, Article 23 of the Freedom of Information (Jersey) Law 2011 has been applied. 

The ADHD service for adults is not a purely diagnostic service. Any patients diagnosed and subsequently prescribed for then require ongoing care by the practitioners in the service, as there is no shared care arrangement for prescribing with General Practitioners in Jersey. As more people are diagnosed, less time is available in the service for diagnostic assessments, thus increasing the waiting time for assessment / diagnosis.
