What Is This Study About?
The experimental drug bisnorcymserine (BNC) may help improve brain function and symptoms in people with Alzheimer's by blocking a chemical that affects how nerve cells in the brain communicate with each other. Researchers want to see how BNC works and whether it is safe in healthy older volunteers.
