For years, I did well on a very small dose of Lexapro. Only recently did I learn that it reduces bone density--I have osteoporosis. Also, I am having memory lapses--some of the research suggests that SSRI's cause memory problems and some articles say they help with memory. I need accurate information for a 66 year old with osteoporosis and memory lapses (with a family history of both osteoporosis and Alzheimers).
