Lifestyle and medical factors linked to dementia risk
Menopausal Hormone Therapy Use Linked to Lower Risk for Alzheimer Disease (Neurologyadvisor)
Summary: A study published online Aug. 12 in Neurology examined the association between estrogen-only menopausal hormone therapy (MHT) use and Alzheimer disease (AD)-related outcomes in women aged 50 years or older from the NACC and ADNI cohorts. Relative to nonusers, MHT users had significantly lower odds of increased AD pathology on autopsy (odds ratio, 0.65), reduced amyloid pathologic load in plasma and cerebrospinal fluid, and lower odds of clinical dementia diagnoses and symptoms of memory/functional decline. The lead author described the effect as modest but meaningful and statistically significant, though less powerful than age, APOE4, or hypertension.
Why it matters: The study provides observational evidence that MHT use is associated with lower odds of AD-related neuropathologic and clinical outcomes, which could inform clinical discussions about MHT use in postmenopausal women.
"MHT appears to exert a modest but meaningful and statistically significant protective effect on the risk of developing Alzheimer’s pathology,” Bruno said in a statement. “While this is by no means more powerful than such very well-known factors as age, possession of the genetic variant [known] as APOE4. or a history of hypertension, it’s nonetheless quite a consistent effect, spanning multiple Alzheimer’s-related outcomes." — NEUROLOGYADVISOR
