The kind of estradiol-based hormone remedy taken throughout and after menopause, corresponding to patches or drugs, could also be related to variations in reminiscence efficiency, in response to a examine printed on August 27, 2025, in Neurology.
The examine discovered when in comparison with folks not taking hormones, these utilizing hormone patches or gels had higher episodic reminiscence, the power to recall previous experiences, and people taking hormone drugs had higher potential reminiscence, the power to recollect to do future duties.

“Hormone therapy is often considered to help manage symptoms of menopause but deciding whether to use it—and which type to use—can be a complex and personal decision,” mentioned examine creator Liisa A. M. Galea, Ph.D., of the Centre for Dependancy and Psychological Well being in Toronto, Canada.
“This study highlights that the type of estradiol therapy used may influence cognitive performance differently across various types of memory. Understanding these links could help inform more tailored approaches to maintaining brain health after menopause.”
The examine included 7,251 cognitively wholesome postmenopausal members utilizing knowledge from the Canadian Longitudinal Research of Growing older. That they had a median age of 61 and reached menopause at a median age of 51.
Members accomplished assessments that measured totally different reminiscence and considering expertise. Episodic reminiscence assessments assessed their skill to recollect phrases and occasions. Potential reminiscence assessments measured how effectively they remembered to do issues sooner or later, corresponding to remembering an appointment later in time. Government perform assessments checked out their planning and problem-solving expertise.
Members reported whether or not they have been utilizing estradiol-based hormone remedy, with 4% utilizing transdermal estradiol within the types of patches or gels utilized to the pores and skin or vaginal rings, lotions or tablets, and a couple of% taking it as drugs. The remaining 94% of members didn’t use hormone remedy.
After adjusting for age, schooling and vascular threat components, researchers discovered that earlier menopause was linked to decrease scores throughout all areas of reminiscence and considering. For govt perform solely, the affiliation was strongest in folks with 4 or extra youngsters and in these carrying the APOE ε4 gene variant, which will increase Alzheimer’s illness threat.
Members who used transdermal estradiol had higher scores on episodic reminiscence assessments than those that by no means used hormone remedy, with the common scores of the 2 teams being a 3rd of an ordinary deviation aside. Those that took estradiol drugs demonstrated higher scores on potential reminiscence than those that by no means used hormone remedy, with the common scores a 3rd of an ordinary deviation aside.
Neither type of remedy was linked to variations in govt perform scores. Throughout all sorts of reminiscence examined, neither the variety of youngsters nor carrying the APOE ε4 gene variant influenced the findings of estradiol hormone therapies on cognition.
“Our findings suggest that the type of estradiol therapy matters, with different forms linked to different types of memory,” Galea mentioned. “While we cannot say hormone therapy causes these effects, it adds to the conversation about how best to support brain health after menopause.”
A limitation of the examine was most members have been white and had larger incomes, which implies the findings will not be the identical for folks of different racial, ethnic or socioeconomic backgrounds. The info additionally didn’t study how hormone remedy dosage, length or timing affect cognition.
