HRT and dementia
Researchers from the Kaiser Permanente health organization in the U.S. have been looking into the effects of hormone therapy on women's risk of developing dementia. They took a large sample of women and asked them about their hormone use during middle age and old age; 1,524 of the women were diagnosed with dementia during the course of the study. The study found that women who took the hormones in both middle age and old age had a similar risk of dementia while women who took hormones only in old age had a 48% higher risk of developing it. Women who took hormones only in middle age had a 26% lower risk of developing dementia.
