How long is the HSE adult ADHD waiting list, and what to do while you wait
People type this question at strange hours. Usually a week or two after something clicked, when the reading has been done and the videos have been watched and the next step is finally a practical one. How long will this take? Six months? Two years? Is it even worth starting?
The honest answer is that there is no single national number, and anyone who gives you one has invented it. That sounds like a dodge. It is not. It is the single most useful thing to understand about the Irish system, because once you know why the number does not exist, you can work out roughly what your own wait looks like and stop refreshing a page that will never tell you.
Nothing here is a diagnosis. Only a qualified clinician can diagnose ADHD. This is a description of how the Irish public system works in 2026. Services and waits change, and they differ from one catchment to the next, so check anything below with the service or your GP.
Why there is no one number
Adult ADHD in Ireland is not one national waiting list. It is a scattering of local services, and the HSE has stated that it does not hold a single national waiting-list figure for it. There are only around seven funded adult ADHD teams in the country. Several regions, including parts of the west, the south east and north Dublin, have no adult service at all. Some catchments have paused new referrals entirely.
Where waits are reported, through media coverage and parliamentary questions, they run from roughly 18 months to four years. That range is not vagueness for the sake of it. It is the actual spread. Two people with identical referral letters, sent the same week, can be looking at completely different timelines because of nothing more than which side of a county boundary they sleep on.
So the question “how long is the list” has no answer. The question “how long is mylist” does, and it is findable.
How to find your own number
This takes about two phone calls and one email, and most people never make them because they assume the answer is unknowable.
- · Ask your GP where the referral actually goes.Not “the HSE.” The name of the team or the service for your catchment. If your GP does not know, that is genuinely common, and it tells you something useful in itself.
- · Ask whether that service is taking adult referrals at all. Some are not, and a referral into a closed service is a letter in a drawer. Better to know in week one than in month fourteen.
- · Ring the service and ask for the current wait in months. Administrative staff will often tell you plainly. Write down the date you asked, because you will want it later.
- · Ask ADHD Ireland what people in your area are reporting. They hear the real-world version, which is sometimes ahead of the official one.
- · Then follow up once every six months. One short, polite email confirming you are still on the list and asking for an estimate. Lists get reorganised, services reopen, letters go astray. Being a name that occasionally appears in an inbox is not queue jumping. It is just not disappearing.
Join it anyway
Even if the number that comes back is grim, put your name down. Your place on the list costs nothing, and holding it does not stop you doing anything else. Plenty of people go private later and are glad the free option was still ticking along in the background.
The public route needs your GP, and only your GP. You cannot refer yourself into a public adult service in Ireland. The private and online route is the opposite: no gatekeeper, fees typically between €930 and €1,500, and waits usually measured in weeks. The costs and waiting times guide puts both routes side by side with the current figures.
This is not an argument for going private. It is an argument against treating the two as a choice you have to make today. For a lot of people the sensible move is both: name on the free list, decision about anything else taken later, with better information.
Waiting is not the same as doing nothing
Here is the part nobody tells you at the GP surgery. A great deal of what makes an assessment go well is preparation you can do for free, on your own, starting this week. Adults routinely arrive at an appointment they waited two years for with a vivid account of the last six months and almost nothing about being eight years old, which is precisely the evidence the clinician needs most.
Four things, none of which cost anything.
- · Dig up the childhood evidence.School reports, copybooks, notes home. ADHD is by definition a pattern that starts early, so every assessment probes childhood hard. An afternoon in your parents' attic is worth more than a month of reading online. The childhood evidence guide walks through where to look.
- · Ask one person who knew you at ten. A parent, an older sibling, an aunt. One open question: what was I like in school? Then stay quiet and write down what they say, in their words, with the date. Memories get less reliable, and people get less available.
- · Keep a two-line-a-day record.Not a journal. Two lines: what fell apart today, and what it cost. Six months of that turns “I'm disorganised” into specifics, and specifics are the currency of an assessment.
- · Get the practical supports going now. ADHD Ireland run support groups around the country and online, plus webinars, and none of it requires a diagnosis or a place on any list. Strategies that help do not check your paperwork first.
If a wait of two years arrives with a folder of dated notes, a parent's account of primary school, and a clear timeline, that appointment does more in ninety minutes than it otherwise could. The assessment guide covers what happens on the day itself.
The thing the wait cannot take from you
There is a quiet grief in being told the answer is two years away, and it deserves naming rather than a pep talk. Two years is a long time to hold a question about your own head.
But the wait is for a clinical decision, and a clinical decision is not the same thing as understanding. Knowing that your brain runs on interest rather than importance, that the systems collapsing in week three were never a character flaw, that the exhaustion has a shape: none of that is issued by a service. You can have it now. The letter, when it comes, changes what you are entitled to. It does not change what is true, and it never was the only thing worth having.
Start with where you stand
Before you spend two years waiting on a question, it is worth knowing whether the pattern you are carrying is one that is actually worth investigating. A screening cannot diagnose anything and it is not an assessment. What it can do is tell you whether what you live with crosses the thresholds clinics use, in about two minutes, for nothing. And whatever the answer, the supports below exist today, with no list and no referral.
