Abstract: OBJECTIVE:: To update for both clinicians and the lay public the evidence-based position statement published by The North American Menopause Society (NAMS) in March 2007 regarding its recommendations for menopausal hormone therapy (HT) for postmenopausal women, with consideration for the therapeutic benefit-risk ratio at various times through menopause and beyond. DESIGN:: An Advisory Panel of clinicians and researchers expert in the field of women's health was enlisted to review the March 2007 NAMS position statement, evaluate new evidence through an evidence-based analysis, and reach consensus on recommendations. The Panel's recommendations were reviewed and approved by the NAMS Board of Trustees as an official NAMS position statement. The document was provided to other interested organizations to seek their endorsement. RESULTS:: Current evidence supports a consensus regarding the role of HT in postmenopausal women, when potential therapeutic benefits and risks around the time of menopause are considered. This paper lists all these areas along with explanatory comments. Conclusions that vary from the 2007 position statement are highlighted. Addenda include a discussion of risk concepts, a new component not included in the 2007 paper, and a recommended list of areas for future HT research. A suggested reading list of key references is also provided. CONCLUSIONS:: Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms; to treat or reduce the risk of certain disorders, such as osteoporosis or fractures in select postmenopausal women; or both. The benefit-risk ratio for menopausal HT is favorable close to menopause but decreases with aging and with time since menopause in previously untreated women.

Abstract: OBJECTIVE: This investigation examined whether raloxifene, a selective estrogen receptor modulator, affects the risk for Alzheimer's disease. METHOD: The Multiple Outcomes of Raloxifene Evaluation was a randomized, placebo-controlled trial among postmenopausal women with osteoporosis. The effect of raloxifene (60 or 120 mg/day) on vertebral fractures was the primary outcome. Development of mild cognitive impairment and dementia was a secondary outcome. Women were given clinical and cognitive evaluations at baseline and annually. After 3 years, among the 5,386 women enrolled at participating sites, those who had clinical symptoms of dementia or scored in the lowest 10th percentile on cognitive screening were evaluated by a blinded dementia specialist and had brain scans and laboratory tests to evaluate dementia etiology. Dementia was diagnosed by a blinded adjudication committee. RESULTS: Of the 5,386 women, 5,153 (95.7%) were classified as cognitively normal, 181 (3.4%) had mild cognitive impairment, and 52 (1.0%) had dementia, 36 with Alzheimer's disease. Compared to those taking placebo, women receiving 120 mg/day of raloxifene had a 33% lower risk of mild cognitive impairment (relative risk, 0.67; 95% confidence interval [CI], 0.46-0.98) and somewhat lower risks of Alzheimer's disease (relative risk=0.52, 95% CI=0.22-1.21) and any cognitive impairment (relative risk=0.73, 95% CI=0.53-1.01). Risks of mild cognitive impairment, Alzheimer's disease, and any impairment were not significantly different in the group taking 60 mg/day of raloxifene. CONCLUSIONS: Raloxifene at a dose of 120 mg/day, but not 60 mg/day, resulted in reduced risk of cognitive impairment in postmenopausal women.
