A study published in Scientific Reports suggests that a hormone treatment combining estriol and progesterone may help ease cognitive symptoms such as memory lapses and trouble concentrating in menopausal women. [^1]

A study published in Scientific Reports in 2026 by UCLA Health evaluated a combined therapy of estriol and progesterone on a small group of 20 menopausal women with an average age of 53. [^2]

After the 12-month treatment regimen, participants reported significant reductions in brain fog and problems with concentration, working memory, processing speed, verbal memory, and problem-solving. [^3]

Dr. Rhonda Voskuhl, a neurologist and senior author of the study at UCLA Health, stated that there is currently no FDA-approved treatment type or dose that specifically targets cognitive symptoms during menopause. [^4]

The study was an observational case series that followed 20 menopausal women with an average age of 53 over a 12-month period. [^5]

Experiments on middle-aged mice showed that estriol reduced markers of pathology in the hippocampus and improved performance in working memory and spatial tasks. [^6]

Researchers declared that confirmation in larger, placebo-controlled clinical trials using standardized brain imaging and cognitive tests is necessary before considering changes in clinical practice. [^7]
