What the literature reports
A Lancet OGWH review describes cognitive symptoms in menopause as self-reported impairment in one or more domains (memory, attention, organisation, problem-solving, word retrieval) in the absence of notable objective decline, which can fluctuate and cause distress. Around two-thirds of women report cognitive concerns during the transition, yet in a large cohort (>14,000) objective cognitive performance differed only minimally across menopause status — the subjective/objective mismatch is the key reported finding.
