Postmenopause, nonetheless, that loss stopped, and in some circumstances mind quantity elevated, although to not its premenopausal measurement. The researchers additionally detected corresponding shifts in how the mind metabolized vitality, however these didn’t have an effect on efficiency on assessments of reminiscence, higher-order processing and language. This implies that the feminine mind “goes via this course of, and it recoups,” says Jill M.
