Dietary Polyphenols as Potential Therapeutics in Alzheimer?s Disease: Pleiotropic Effects and Toxicity Prediction Models

Efstathia Kalli, Vlamos Panayiotis

Individualized nutritional treatment with polyphenols has been proposed in the early stages of Alzheimer’s disease. However, it remains unclear at what doses polyphenols and their metabolites enter the brain tissue and whether they can act at sufficient concentrations. The present review provides useful insights into the multiple modes of actions of selected polyphenols as potential therapeutic tools at the pre-clinical stage of Alzheimer’s disease, as well as their ability to cross the blood-brain barrier and their detrimental effects after high dose consumptions. Several studies proposed flavonoids for their potential value in prevention and treatment of neurodegenerative diseases. The scarcity of clinical data though highlights the need for conducting metabolomics studies and well-designed clinical trials. Prolonged clinical trials with bioinformatics tools are needed to fully elucidate both neuroprotective effects and possible risks from polyphenol consumption at concentrated high doses.
