Cognitive changes in perimenopause are real, measurable and — importantly — usually temporary. Studies of women through the transition consistently show dips in verbal memory and processing speed that recover afterwards.

Why it hits hardest at work

This stage often coincides with the most senior, most visible years of a career. The gap between how capable you are and how capable you feel in a 9am meeting is where confidence quietly erodes.

Practical protections

  • Front-load complex work into your sharpest hours and defend them
  • Write the three key points before any meeting you'll speak in
  • Treat sleep and strength training as performance infrastructure, not self-care
  • Ask your employer what support exists — increasingly, something does
