Research Abstract

Estrogen decline after menopause may influence cognitive performance and increase risk for Alzheimer's disease (AD) in women. We have previously found that combination of chronic stress and ovariectomy (OVX) causes memory impairment in mice. In this study, we found that cholinergic neuronal loss in the hippocampal CA3 region is involved in OVX/stress-induced memory impairment in mice, and donepezil and galantamine, which are clinically used for AD therapy, improved the memory impairment.
