PCOS and ADHD: What the Co-Occurrence Data Shows
7 min read
A registered dietitian and clinician review is being arranged for this site. Until this article carries a named reviewer, treat it as a well-sourced summary of published guidance — not as a substitute for advice about your own case.
The short answer
Women with PCOS scored higher on ADHD self-report scales than controls in a 2015 study of 80 women, driven specifically by hyperactivity and impulsivity, not inattention. The literature is small, mostly single studies, and association is not the same as causation. This is co-occurrence data, not a basis for self-diagnosis.
What does the co-occurrence data between PCOS and ADHD actually show?
Women with PCOS scored significantly higher on both the Adult ADHD Self-Report Scale and the Wender-Utah Rating Scale than women without PCOS, in a study of 40 women with PCOS and 40 healthy controls aged 18 to 35 (Hergüner et al., 2015). The Wender-Utah scale, which asks about childhood symptoms retrospectively, found significantly higher rates of childhood ADHD symptoms in the PCOS group as well. This is one of the only studies to test ADHD symptoms directly in adult women with PCOS, rather than in their children, and it is exactly the kind of small, single-study finding that needs replication before it becomes a settled fact — a point the study’s own authors made explicitly, writing that “further studies are needed to investigate the association between PCOS and ADHD.”
Note: in May 2026, PCOS was renamed polyendocrine metabolic ovarian syndrome, or PMOS, by a global consensus of more than 50 organisations. Same condition, same co-occurrence data — only the label changed. This article uses PCOS, since that is still the term most readers search.
Is this about attention, or specifically about hyperactivity and impulsivity?
The 2015 study found no significant difference in inattention scores between women with PCOS and controls, either currently or recalled from childhood — only the hyperactivity-impulsivity and behavioural-problems subscales were significantly elevated (Hergüner et al., 2015). That distinction matters: “PCOS and ADHD” gets discussed as a single link, but the data so far points at one specific cluster of symptoms rather than the inattentive presentation most people picture when they think of adult ADHD. If your own experience is mainly about attention and focus rather than restlessness or impulsivity, this particular study does not describe your pattern as clearly as it might seem to from the headline finding.
Could androgens explain the overlap, given that PCOS raises testosterone?
Partly, and unevenly across the research that exists. Higher free testosterone was linked to worse performance on verbal fluency, verbal memory, manual dexterity and visuospatial working memory in a study comparing 29 women with PCOS to 22 healthy controls (Schattmann & Sherwin, 2007), and a larger, more recent study of 81 women — 40 with PCOS — found that higher free testosterone correlated with poorer psychomotor speed and visuospatial learning, independent of depression or anxiety symptoms (Sukhapure et al., 2022). Both point toward androgens affecting specific cognitive domains. But the Hergüner study above found no hormone correlation with ADHD symptom scores specifically, which means the androgen story is not a clean, single explanation that ties every finding together — it is two separate lines of evidence that overlap in subject matter without yet meeting in a single mechanism.
What does “PCOS executive function” actually refer to?
“Executive function” in this research covers a cluster of measurable skills — working memory, processing speed, verbal fluency, and the ability to hold and manipulate information — rather than a single test or a diagnosis. Across the cognitive studies above, the specific domains that came back weaker with higher androgen levels were visuospatial working memory, psychomotor speed, verbal fluency and verbal memory, not a uniform decline across every cognitive measure tested. PCOS brain fog covers the broader cognitive-symptom picture, of which this executive-function research is one specific, better-quantified slice.
| Study | Population | What it found |
|---|---|---|
| Hergüner et al., 2015 | 40 women with PCOS, 40 controls, aged 18-35 | Higher ADHD self-report scores, driven by hyperactivity-impulsivity; inattention not significantly different; no hormone correlation |
| Schattmann & Sherwin, 2007 | 29 women with PCOS, 22 controls | Worse verbal fluency, verbal memory, manual dexterity and visuospatial working memory in PCOS |
| Sukhapure et al., 2022 | 81 women, 40 with PCOS | Higher free testosterone correlated with worse psychomotor speed and visuospatial learning |
| Kosidou et al., 2017 | Swedish registry: children of mothers with and without PCOS | Maternal PCOS associated with 42% higher odds of offspring ADHD (a different population — see below) |
Does having a mother with PCOS raise a child’s own ADHD risk?
Maternal PCOS was associated with 42% higher odds of an ADHD diagnosis in the child, in a Swedish registry study matching 58,912 children with ADHD to 499,998 controls by sex and birth year, after adjustment for confounders (Kosidou et al., 2017). This is a genuinely different question from everything above it on this page: it measures ADHD risk in the children of women with PCOS, not in the women themselves, and the proposed mechanism is prenatal androgen exposure during pregnancy rather than anything happening in an adult reader’s own brain right now. It is relevant context for the broader androgen-and-neurodevelopment story, and it is not a statistic about your own odds of having, or having had, ADHD.
Who this does not describe, and where the evidence runs out
The direct adult-women evidence rests on a single study of 80 women — real, but not the kind of sample size or replication record that supports strong claims either way. Self-report symptom scales measure symptoms, not a clinical ADHD diagnosis, and a higher score on a screening tool is not equivalent to meeting diagnostic criteria. The cognitive-testing studies used small samples too, and none of this research followed anyone over time to establish which came first or whether either condition changes the other. If you do not experience hyperactivity, impulsivity, or focus difficulties, this research says nothing about you specifically — it describes a group-level pattern in specific study samples, not a symptom every woman with PCOS should expect to have.
Frequently asked questions
Common questions
Is there a real link between PCOS and ADHD?
One study of 80 women found higher ADHD symptom scores in those with PCOS, driven mainly by hyperactivity and impulsivity rather than inattention. It is a real finding worth knowing about, but it comes from a single study that has not been widely replicated in adult women.Does PCOS affect executive function?
Small studies have found that higher free testosterone in women, including women with PCOS, correlates with worse performance on visuospatial working memory, psychomotor speed and verbal fluency. This describes specific, measurable cognitive domains, not a general decline in every function.Does having PCOS mean I probably have ADHD?
No. The available research shows a group-level association in one study of 80 women, not that PCOS causes ADHD or that most women with PCOS have it. Self-diagnosing from this data is not supported by what the studies actually measured.If my mother had PCOS, am I more likely to have ADHD?
The relevant study found children of mothers with PCOS had 42% higher odds of an ADHD diagnosis, not that the mother's own risk was elevated. That is a separate question from whether PCOS itself is associated with ADHD symptoms in the women who have it.Why would androgens connect PCOS and ADHD at all?
Androgens are implicated in ADHD biology generally, and separate research links higher free testosterone in women to specific cognitive effects. But the one study measuring ADHD symptoms directly in women with PCOS found no correlation with hormone levels, so this remains a plausible mechanism rather than a confirmed one.
Your next step
Treat this as evidence worth knowing, not a checklist to self-diagnose from. If attention, hyperactivity or impulsivity genuinely affects your daily functioning and has done so since childhood, ask your doctor for a referral to a clinician who does formal ADHD assessments — that evaluation, not a symptom scale you fill out alone, is the accurate next step regardless of what your PCOS diagnosis does or does not suggest about the odds. It sits alongside the handful of other associations — not diagnostic features — that the wider PCOS symptom picture covers separately from the two-of-three criteria that actually confirm a diagnosis.
