Perimenopause
Anxiety and brain fog, not hot flashes, are now women's top menopause complaint
For years, menopause conversations have centred on hot flashes. New survey data suggests that's no longer the symptom women say is hardest to live with.
Bonafide Health's sixth annual State of Menopause survey, covering more than 2,000 US women aged 40–64, found that anxiety, brain fog and declining motivation now top the list of menopause complaints — overtaking hot flashes for the first time since the survey began.
The shift matters because it's rarely what women expect, or what they're told to expect. Hot flashes are visible and easy to name; feeling anxious, scattered or unmotivated is easier to write off as stress, burnout or "just a bad patch" — especially in your 40s, when work and family pressures are already high.
The survey also points to a real financial cost. 56% of respondents said declining motivation was the symptom most affecting their work, and 48% said their symptoms had negatively impacted their income — with 23% reporting losses of $10,000 or more.
None of this means every low mood or foggy week is menopausal. But if you're 40 or older and notice a cluster of anxiety, mental fatigue and flagging drive that doesn't match your usual patterns, it's worth raising perimenopause specifically with your doctor — rather than defaulting to a stress or mental-health diagnosis alone.
What the research says
Bonafide Health's sixth annual State of Menopause survey of over 2,000 US women aged 40–64 found mental and cognitive symptoms now rank above hot flashes for the first time. 56% said declining motivation most affected their work performance; 48% said menopause symptoms had negatively impacted their income, and 23% reported losing $10,000 or more as a result.

Is anxiety really a menopause symptom, or is it just stress?
Both can be true at once, which is what makes it hard to spot. Hormonal shifts in perimenopause directly affect mood-regulating brain chemistry, and a 2026 survey of over 2,000 women found anxiety and brain fog now rank as the top menopause complaint, ahead of hot flashes. If new anxiety or fog appears alongside other perimenopause signs — irregular cycles, sleep changes, mood swings — it's worth mentioning to your doctor as a possible hormonal factor, not only a stress issue.
Why don't more women realise brain fog can be a menopause symptom?
Because public awareness and clinical guidance have historically centred on hot flashes as the defining symptom. Newer, larger surveys are showing that cognitive and mood symptoms are actually more common complaints for many women, but that message hasn't caught up with general expectations yet — which is part of why so many women attribute these changes to burnout instead.
