but I have to say there is something good in this article:
Hormone Replacement Therapy: Both Good and Bad for the Female Brain?
U.S. News's Bernadine Healy, M.D., ponders a paradox of estrogen, which has been called "the memory molecule." Hormone replacement therapy, which contains
estrogen, was found to shrink some older women's brains, a change associated with Alzheimer's, in a recent study out of Wake Forest University. Healy draws attention to a particular aspect of the findings, which may be too easily overlooked, noting: Brain shrinkage and accelerated development of Alzheimer's were not observed in all older women on the hormones but mainly in those whose brains were already deteriorating.
The finding has neuroscientists all atwitter, because it may help clarify the nature of estrogen, which giveth (it aids the growth of new neurons) and also taketh away (estrogen can slay neurons, says Healy, if they're already weak).
Have a great day!
