A recent study investigated this question in detail. The researchers examined the insurance claims of 379.352 women aged 45+ who were in menopause and found that women on hormone therapy were up to 58% less likely to develop any kind of neurodegenerative disease (f.e. Alzheimer’s disease, Parkinson’s, MS and ALS). The degree of the decreased risk turned to vary by type and route of hormone therapy and duration of use.
To be more specific:
- using the natural steroids estradiol or progesterone resulted in greater risk reduction than the use of synthetic hormones;
- oral hormone therapy reduced the risk for combined neurodegenerative diseases, while hormone therapy administered through the skin reduced the risk of developing dementia;
- the protective effect of therapy lasting longer than 1 year on Alzheimer’s, Parkinson’s and dementia was greater than with short-term therapy of less than 1 year. The best effect was noted in women who underwent menopausal hormone therapy for 6+ years. This helped decrease the risk of Alzheimer’s by 79% (!) and any other neurodegenerative disease by 77% (!).
The best results were achieved in women at the age of 65+ years old.
The results of this study are remarkable. They allow to use hormone therapy not only as a guide for women in the menopause but also as a tool to keep their brain healthy by preventing neurodegenerative diseases in the near future.
