Hormone Therapy for Breast Cancer Linked to Lower Dementia Risk

Study shows a 7% reduced risk of Alzheimer's and related dementias, with effectiveness varying by age and race.

Research analyzed data from over 18,800 women aged 65 and older diagnosed with breast cancer between 2007 and 2009.
Hormone therapy users had a lower incidence of dementia compared to non-users, particularly in women aged 65-69.
The protective effect of hormone therapy decreased with age and was not observed in women over 80.
Black women aged 65-74 saw a 24% reduction in dementia risk, while white women in the same age group saw an 11% reduction.
The study highlights the need for personalized treatment plans based on individual patient factors.
