There's a link late in that article (this one) to a study that concluded: "Consistent with transitioning women's perceived memory difficulties, perimenopause was associated with a decrement in cognitive performance, characterized by women not being able to learn as well as they had during premenopause. Improvement rebounded to premenopausal levels in postmenopause, suggesting that menopause transition–related cognitive difficulties may be time-limited."

This gives me a LOT of hope! Thank you very much, Monica!
