AUTHORS ' CONCLUSIONS : Women with intolerable menopausal symptoms may wish to weigh the benefits of symptom relief against the small absolute risk of harm arising from short-term use of low-dose HT , provided they do not have specific contraindications .
HT may be unsuitable for some women , including those at increased risk of cardiovascular disease , increased risk of thromboembolic disease ( such as those with obesity or a history of venous thrombosis ) or increased risk of some types of cancer ( such as breast cancer , in women with a uterus ) .
The risk of endometrial cancer among women with a uterus taking oestrogen-only HT is well documented .
HT is not indicated for primary or secondary prevention of cardiovascular disease or dementia , nor for prevention of deterioration of cognitive function in postmenopausal women .
Although HT is considered effective for the prevention of postmenopausal osteoporosis , it is generally recommended as an option only for women at significant risk for whom non-oestrogen therapies are unsuitable .

Effect of estrogen plus progestin on global cognitive function in postmenopausal women: the Women's Health Initiative Memory Study: a randomized controlled trial.
CONTEXT Observational studies have suggested that postmenopausal hormone treatment may improve cognitive function , but data from r and omized clinical trials have been sparse and inconclusive . The Women 's Health Initiative Memory Study ( WHIMS ) is an ancillary study of the Women 's Health Initiative ( WHI ) hormone therapy trials . On July 8 , 2002 , the estrogen plus progestin therapy in the WHI trial was discontinued because of certain increased health risks for women . OBJECTIVE To determine whether estrogen plus progestin therapy protects global cognitive function in older postmenopausal women . DESIGN , SETTING , AND PARTICIPANTS A r and omized , double-blind , placebo-controlled clinical trial , WHIMS is an ancillary study of geographically diverse , community-dwelling women aged 65 years or older from 39 of 40 clinical centers within the WHI estrogen plus progestin trial that started in June 1995 . Of 4894 eligible postmenopausal women aged 65 years or older and free of probable dementia at baseline , 4532 ( 92.6 % ) were enrolled in the estrogen plus progestin component of WHIMS . A total of 4381 participants ( 96.7 % ) provided at least 1 valid cognitive function score between June 1995 and July 8 , 2002 . INTERVENTIONS Participants received either 1 daily tablet containing 0.625 mg of conjugated equine estrogen with 2.5 mg of medroxyprogesterone acetate ( n = 2145 ) or matching placebo ( n = 2236 ) . MAIN OUTCOME MEASURE Global cognitive function measured annually with the Modified Mini-Mental State Examination . RESULTS The Modified Mini-Mental State Examination mean total scores in both groups increased slightly over time ( mean follow-up of 4.2 years ) . Women in the estrogen plus progestin group had smaller average increases in total scores compared with women receiving placebo ( P = .03 ) , but these differences were not clinical ly important . Removing women by censoring them after adjudicated dementia , mild cognitive impairment , or stroke , and nonadherence to study protocol , did not alter the findings . Prior hormone therapy use and duration of prior use did not affect the interpretation of the results , nor did timing of prior hormone therapy initiation with respect to the final menstrual period . More women in the estrogen plus progestin group had a substantial and clinical ly important decline ( > or = 2 SDs ) in Modified Mini-Mental State Examination total score ( 6.7 % ) compared with the placebo group ( 4.8 % ) ( P = .008 ) . CONCLUSIONS Among postmenopausal women aged 65 years or older , estrogen plus progestin did not improve cognitive function when compared with placebo . While most women receiving estrogen plus progestin did not experience clinical ly relevant adverse effects on cognition compared with placebo , a small increased risk of clinical ly meaningful cognitive decline occurred in the estrogen plus progestin group
