Claims this source supports

• Puberty and pregnancy were both associated with accelerated monthly reductions in total and cortical grey matter compared with controls, in overlapping regions including the prefrontal, parietal, and temporal association cortices (van 't Hof et al., Nat Commun 17, 9360, 2026).
• The menopause transition showed no notable total or cortical grey matter reduction compared with pre- and postmenopausal control groups; grey matter volume remained relatively stable during the transition itself.
• The authors conclude that puberty, pregnancy, and menopause are associated with different patterns of brain structural change, rather than a single uniform response to hormonal change. Menopause is not simply puberty in reverse.
• Stated limitations: self-reported menopausal status and lack of directly measured hormonal data across all cohorts, so the link between sex-steroid changes and the observed patterns is an inference, not an established cause.
