Exelon is used in the treatment of mild to moderate Alzheimer's disease. Alzheimer's disease causes physical changes in the brain that disrupt the flow of information and interfere with memory, thinking, and behavior. By boosting levels of the chemical messenger acetylcholine, Exelon can temporarily improve brain function in some Alzheimer's sufferers, though it does not halt the progress of the underlying disease. Exelon may become less effective as the disease progresses.
