The trait was lifelong; only the diagnosis was late
Christina Kini-Seery and colleagues at University College Dublin, working with ADHD Ireland and Ireland’s national ADHD clinical programme, published a qualitative study in Women’s Health in 2026 that set out to do something surprisingly under-attempted: ask women with ADHD what perimenopause is actually like for them. Nineteen women aged between 29 and 62 were interviewed in depth, their accounts analysed thematically. It is a small, self-selected sample — recruited through an ADHD charity, so weighted toward those with something difficult to report — and the study is candid about that. But the pattern that emerges is striking enough to be worth sitting with.
Of the thirteen women who had a formal ADHD diagnosis, ten received it after their perimenopause symptoms had already begun. The diagnosis, for most of this group, was not a feature of childhood or early adulthood. It arrived in midlife, in the middle of a hormonal transition — and the women themselves are clear about why. The reason they give is not that ADHD appeared in perimenopause. It is that the things they had been using to manage it, mostly without knowing that was what they were doing, stopped working.
One participant put it precisely: knowing now that she had ADHD all along, she had been using ways to manage it without realising, and when perimenopause began, those coping mechanisms were no longer sustainable. Every one of the nineteen reported that perimenopause exacerbated their executive-function difficulties — the working memory, the focus, the emotional regulation. The ADHD did not switch on. The compensation switched off. This matters because it is, in effect, a natural experiment. Perimenopause lowers and destabilises oestrogen; oestrogen supports dopamine signalling in the executive circuits ADHD already taxes; so the transition strips away a hormonal support the woman had been leaning on, often invisibly, for decades. What it exposes when it does is the question the whole piece turns on.
The system detects the collapse of coping, never the neurotype beneath it
Set the pattern against how ADHD diagnosis is supposed to work, and something uncomfortable comes into view. The diagnostic criteria describe a set of traits. The assumption is that the traits are what get detected: that the assessment finds the neurotype. What the perimenopause data suggests is that the apparatus does not reliably detect the neurotype at all, but it does detect the failure to compensate for it.
A woman with ADHD who has built a scaffolding of coping strategies — lists, routines, overwork, masking, sheer effort — and who is supported by a hormonal environment that keeps her dopamine circuits functioning, presents to the world, and to any clinician, as someone without ADHD. She is managing. Nothing triggers assessment. The traits are all present, but they are compensated, and compensated traits are invisible to a system that only looks when someone is visibly struggling.
Remove the hormonal support, exhaust the coping strategies, and the same woman — with the same brain she has always had — becomes legible to the apparatus for the first time. So the late diagnosis is not the correction of an earlier oversight, exactly: it is the apparatus finally being able to see something it was never equipped to detect while it was being successfully managed.
This is a sharper and more specific claim than the familiar one that “ADHD criteria were calibrated to boys and therefore miss women” — that is absolutely true, and it is about what the criteria describe. This, though, is about what triggers detection in the first place. Even with perfect criteria, a system that only diagnoses visible impairment will systematically miss every person who is compensating well, and will “find” them only at the moment their compensation collapses — such as a hormonal transition that outstrips their strategies. The diagnosis tracks the breakdown of coping, not the presence of the trait.
I’ve argued a version of this before in other settings — that measures calibrated to catch struggle mistake the absence of visible struggle for the absence of the underlying difference. Here the mechanism is unusually clean, because you can date it. The trait was constant across the woman’s whole life. The detection happened the year her oestrogen fell.
Unseen twice: the neurotype, and then the transition that exposed it
The study’s third theme adds a second detection failure stacked on the first, and it happens in the consulting room. Having finally reached the point where their ADHD became undeniable, many of these women then struggled to get the perimenopause itself recognised. Their accounts of seeking help are a catalogue of being unseen twice over.
Women in their mid-forties reported being told they were too young for their symptoms to be perimenopause. One who did not experience hot flushes was told that meant she was not perimenopausal at all — her presentation did not match the stereotype, so it was dismissed. Others had their symptoms attributed to depression and were steered toward therapy or told they were simply stressed, which delayed access to hormone replacement therapy that, when finally prescribed, several described as transformative. The pattern the authors note is that women with ADHD may reach perimenopause earlier and present atypically — and an assessment system built around the typical case fails them at exactly the point of greatest need.
There is a small, sharp irony folded into the treatment itself, and it is worth naming because it is the same structural point in miniature. HRT worked — for cognition, mood, and physical symptoms, women reported real benefit. But the regimens demand precisely the executive function that ADHD, amplified by perimenopause, has depleted: patches to be changed twice a week on varying schedules, gels and pills to be remembered daily, multiple formulations to be juggled. The treatment for the condition presupposes the capacity the condition removes. The system offers a solution and then requires, in order to use it, exactly the resource it has just documented the woman as lacking.
Unmasking as the measure of a burden carried uncounted for decades
The study’s final theme is the one that could be mistaken for a soft landing, and isn’t. Some women described perimenopause, for all its difficulty, as bringing something valuable: a diagnosis that finally explained a lifetime, a new self-compassion, and — repeatedly — permission to stop masking. One described it as going through a fire that burns off everything you no longer need.
Read against the rest of the study, that unmasking is not a consolation. It is evidence. These women stopped masking largely because they no longer could — perimenopause had exhausted the executive resource that masking runs on. And what several of them reported, once the masking fell away, was relief. The clear implication is that the masking had been costing them something enormous all along, quietly, for decades — a cost that only became visible when they ran out of the capacity to pay it. The “positive” of unmasking is really a measurement of the burden of the mask.
Which brings the whole study back to a single point about what has been invisible. The late diagnosis, the compensation collapse, the healthcare dismissals, the relief of unmasking — all four themes are describing the same thing from different angles: a population that was managing an unrecognised load, at a cost no one was counting, until a hormonal transition made the load impossible to carry and therefore, finally, impossible to ignore.
The women did not change in perimenopause. What changed is that the effort they had always been making became visible — to their clinicians, and to themselves. The honest reading of this study is not that perimenopause gives women ADHD. It is that perimenopause is where a lifetime of uncounted compensation finally shows up on the books.
The authors’ practical call follows directly: integrated care that treats ADHD and perimenopause together rather than as separate queues, and clinicians who know that a woman with ADHD may arrive at perimenopause early, present atypically, and have spent decades compensating for a neurotype no one ever named. For the women in this study, recognition came late and hard. The point of research like this is that for the women coming behind them, it might not have to.
