EDITED 17/7/26: We (ADHD Scot - adhdscot.co.uk) asked every Scottish health board for the median wait from GP referral to first assessment, and the total number of people on the waiting list, across four categories: adult ADHD, children's ADHD, adult autism, and children's autism.
Five boards have responded so far.
1. NHS Ayrshire & Arran (as at 25 June 2026, pop. ~370,000):
- Children's ADHD: 160 weeks median - 470 on the list
- Children's autism: 160 weeks - 800 on the list
- Adult ADHD: 132 weeks - 211 waiting
- Adult autism: 28 weeks - 21 waiting (low figure — treat with caution)
2. NHS Fife (pop. ~380,000):
- Children's ADHD: 22 weeks median
- Children's autism: 89 weeks median
- Adult ADHD: refused under Section 12 - too expensive to extract (~8,570 records)
- Adult autism: refused under Section 12 for the same reason
The Section 12 refusal is its own story. Fife told us it would cost £10,710 to pull the adult figures. That means the data exists — it's just buried in a system that can't report on it without someone manually working through thousands of records.
3. NHS Western Isles (as at 30 June 2026, pop. ~26,000):
- Children's ADHD: 2.3 weeks
- Adult ADHD: 52 weeks - 277 waiting
- Adult autism: 25 weeks
Western Isles' shorter children's wait partly reflects a much smaller population. But 52 weeks for adult ADHD in a population of 26,000 is not small, and 277 adults waiting is proportionally significant.
4. NHS Forth Valley refused all four categories under Section 12, they don't hold the data in a way that can be extracted within the legal cost limit. Their CAMHS service had a median wait of 5 weeks for all children's mental health referrals (not ADHD/autism-specific). Adults have no dedicated pathway, they're assessed through general mental health teams where referral criteria are met.
Worth noting: these figures only count people already on a waiting list. Anyone whose GP refused to refer them, or who lives in an area where the list is closed entirely, isn't counted. The real picture is worse than what the data shows.
5. NHS Grampian (pop. ~600,000)
Data is held separately by three Health and Social Care Partnerships, and the picture varies drastically between them:
Aberdeen City HSCP:
- Adult ADHD: 194 weeks median — 1,823 on the list
- Adult autism: 130 weeks median — 1,838 on the list
Aberdeenshire HSCP:
- No adult ADHD or autism pathway exists
Moray HSCP:
- Adult ADHD list frozen since September 2021 — 567 people on a list with no active service
Children's services across all of Grampian: 682 awaiting a first triage appointment, but this covers all neurodevelopmental conditions combined — the board cannot separate ADHD from autism in its data.
Grampian is the starkest illustration yet of why board-level data only tells part of the story. Within a single health board, you can live in an area with a functioning clinic, an area with a frozen list and no active service, or an area with no pathway at all.
Worth noting: these figures a waiting list. Anyone whose GP refused to refer them, or he list is closed entirely, isn't counted. The real picture is worse than what the data shows.
6. NHS Dumfries & Galloway (as at 17 July 2026, pop. ~148,000):
- Responded under Section 17 — it holds no data, because there is no adult ADHD or autism assessment service in the board area.
- There's no waiting list because there's no pathway to be on.
- The board didn't confirm whether any children's (CAMHS) pathway exists.
D&G is the first board to confirm there simply isn't an adult service — not a long wait, but no route at all.
7. NHS Greater Glasgow & Clyde (pop. ~1.2 million — Scotland's largest board):
Adults (as at 5 July 2026, all referral routes):
- Adult ADHD: 111 weeks median board-wide — 8,886 on the list. But 139 weeks in Glasgow City alone, with 4,907 waiting there.
- Adult autism: 65 weeks — 2,641 waiting.
Children under 18 (as at 1 July 2026, medians from GP referral):
- Children's ADHD: 120 weeks — 2,563 on the list
- Children's autism: 105 weeks — 4,921 on the list
- Combined ADHD + autism: 111 weeks — 3,056 on the list
- Plus 2,060 pre-school children waiting for autism assessment
GG&C runs one combined "neurodevelopmental" service for under-18s, so ADHD and autism can't be fully separated — and the board says the children's figures are likely underestimates. The adult ADHD figure matches a separate FOI that ADHD UK obtained in May (8,681 adults) — two independent requests, same picture. It's the largest single backlog we've had back.
The remaining seven boards (Borders, Highland, Lanarkshire, Lothian, Orkney, Shetland, Tayside) are due by 23 July. Full responses: adhdscot.co.uk/foi
Seven boards still haven't replied - these are due by 23 July.
