New research published in npj Women’s Health suggests that the “brain fog” many women report during the menopause transition may not always translate into large measurable drops in cognitive performance, even though the symptoms themselves are real and common. In a large community cohort of 14,234 females aged 45 to 55, perimenopausal and postmenopausal participants were more likely than premenopausal women to report cognitive symptoms such as memory problems and mental slowing, but objective test results changed only minimally across groups.
What the study found
The study examined self-reported cognitive symptoms alongside performance on eight online cognitive tasks. Perimenopausal participants had higher odds of reporting cognitive symptoms than premenopausal women, and postmenopausal participants also showed elevated odds. At the same time, the differences in objective cognition were small, with perimenopausal women showing only marginally higher accuracy on some measures than the other groups.
Researchers said the findings underline the importance of recognising cognitive complaints as part of menopausal care, rather than dismissing them simply because standard tests may not detect major impairment. The work also suggests that subjective symptoms and objective performance are not the same thing, and may be influenced by different biological or psychological factors.
Why the findings matter for UK women’s health
For clinicians and women navigating midlife health changes, the results add nuance to a debate that has often focused on whether menopause causes measurable cognitive decline. The evidence here indicates that while women may genuinely experience forgetfulness or “brain fog”, those symptoms do not necessarily mean a broad drop in cognition is happening. That distinction could shape how doctors discuss menopause, evaluate symptoms, and decide when further assessment is needed.
The study also aligns with wider scientific interest in the menopause transition and brain health. Recent work published in Nature Reviews Neurology describes menopause as a key area for neurological research, reflecting growing attention to how hormonal changes may interact with memory, mood, and longer-term brain health.
A symptom that deserves attention, not dismissal
The authors’ main message is practical: women reporting cognitive changes during menopause should be taken seriously, even when brief screening tools appear normal. The study does not show that menopause has no effect on thinking; rather, it suggests that the lived experience of cognitive symptoms may be more complex than a single test score can capture.
As more research looks at the biological and psychological drivers of menopausal symptoms, the findings could help shape more tailored conversations in primary care and specialist settings. For now, the study adds evidence that “brain fog” is a meaningful symptom to discuss, monitor and manage as part of broader menopause care.
