Namenda is used to treat moderate to severe confusion (dementia) related to Alzheimer’s disease. It does not cure Alzheimer’s disease, but it may improve memory, awareness, and the ability to perform daily functions. This medication works by blocking the action of a certain natural substance in the brain (glutamate) that is believed to be linked to symptoms of Alzheimer’s disease.
