Memory Study of Youngest Women Enrolled in the Women's Health Initiative Hormone Therapy (HT) Arm

Women's Health Initiative Memory Study of Younger Women

WHIMS-Y provides valuable information on the long-term effects on risk of cognitive impairment of hormone therapy in a subset of WHI participants in the WHI Hormone Trials. Following cessation of study-prescribed HT cognitive function and impairment were assessed.

The Women's Health Initiative Memory Study of Younger Women (WHIMS-Y) is proposed to assess the long-term impact of random assignment to postmenopausal hormone therapy (equine estrogen alone or in combination with medroxyprogesterone versus placebo) among women who were aged 50-54 at the time of randomization into the WHI hormone trials. Secondary objectives relate to the consistency of any treatment effects across unopposed or opposed therapy and whether there exists evidence of graded relationships between cognitive effects and age of administration, years from menopause, and baseline risk factors for cognitive impairment.
