About

This is a 15-month study to determine the effectiveness of hormone replacement therapy in improving memory and the ability to live independently in postmenopausal women with Alzheimer's disease.

Full description

Estrogen is a naturally occurring hormone produced in a woman's body. The purpose of this 15-month study is to determine the effectiveness of hormone replacement therapy in improving memory and the ability to live independently in postmenopausal women with Alzheimer's disease and without other dementias. Patients who volunteer for this study will either receive a patch containing 17-ß-estradiol or will receive an inactive placebo patch. In addition, patients will be given either medroxyprogesterone or an inactive placebo pill. Neither the volunteers nor the study staff will know which type of patch or pill a patient receives. Patients must be generally healthy and have mild-to-moderate dementia. There must be a patient caregiver who can watch for side effects and ensure that the patient takes the study medications on schedule. Patients will undergo neuropsychological tests and an evaluation of the ability to live independently at each visit as well as laboratory evaluations, such as the taking of blood. Each visit will last approximately 3 hours. A total of 160 participants are being recruited.
