This paper concludes that it is imperative to identify effective, early treatments for Alzheimer's disease. Creatine is an important bioenergetic molecule, and the Creatine system is shown to be dysfunctional in the brain of individuals with Alzheimer's disease. Therefore, Ceatine may serve as a potential target for prevention and therapy and creatine monohydrate supplementation may be beneficial in Alzheimer's disease. To date, only rodent studies have investigated the use of creatine monohydrate as a treatment for Alzheimer's disease.. Thus, clinical trials investigating the effects of creatine monohydrateon cognition and creatine monohydrate’s mechanisms in humans with Alzheimer's disease as well as its potential as a strategy to prevent cognitive decline in those with normal cognition, are needed. There is much to be learned about CrM intervention and brain health in different life and disease phases.
