People with Alzheimer's disease are at an increased risk of bone fracture. Some studies have shown that those taking donepezil have a lower rate of bone fractures, but the reasons for this are unknown. The purpose of this study is to measure the effect of donepezil treatment on bone metabolism factors including bone mineral density, bone turnover markers, and bone quality. Participants in this study will have a bone density test and have blood samples collected at the baseline study visit. Participants will then be assigned to donepezil to be taken daily by mouth for 12 months. Blood samples will be collected at 6 and 12 months. A repeat bone density test will be performed at 12 months. Participants will also complete questionnaires at each study visit.
