Memory Decline After Menopause Linked to Loss of Estrogen Production in Brain

A new Northwestern Medicine preclinical study reveals that memory loss following menopause may be connected to declining estrogen production within brain tissue itself, rather than solely from the ovaries. Researchers identified a previously overlooked space between brain cells as a critical area where estrogen is produced locally. This discovery could explain why some women experience cognitive changes during menopause and may lead to new therapeutic approaches. Understanding this mechanism is particularly important for developing targeted treatments that address brain-specific estrogen deficiency in postmenopausal women.
