ADHD diagnoses for over 18 year olds (FOI)

ADHD diagnoses for over 18 year olds (FOI)

Produced by the Freedom of Information office
Authored by Government of Jersey and published on 17 May 2024.
Prepared internally, no external costs.



Please advise the number of over 18 year olds diagnosed with ADHD in Jersey each year from 2002 to 2022 inclusive.


Please provide a breakdown for each year of the number of people each year diagnosed under eighteen versus over eighteen.


Please confirm how much funding is set aside currently to support adults with ADHD in the island?



There is no central record of the number of individuals diagnosed with ADHD each year. Information on date of diagnosis is available within individual records only. As records are not held in a format that allows for this information to be discerned without manual interrogation, and as examining the records of all individuals in scope would exceed the timescales prescribed in the Freedom of Information (Costs) (Jersey) Regulations 2014, Article 16 of the Freedom of Information (Jersey) Law 2011 has been applied.


The Freedom of Information (Jersey) Law 2011 gives a right to request information that is held in recorded form, unless exempt. As noted in response to Question 1, annual figures for adults diagnosed with ADHD are not available in a central record. The number of under 18s diagnosed with ADHD each year, from 2002 to 2022 (inclusive), in Jersey is not held in a recorded format. Therefore, Article 3 of the Freedom of Information (Jersey) Law 2011 applies.


The 2023 service costs for Health and Community Services’ Adult ADHD Service are detailed in a Freedom of Information response published to in May 2024:

ADHD referrals to CAMHS (FOI)​

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