Alzheimer's disease(AD)is most common in all dementia types in the elderly.Various researches have been done for studying its pathogenesis, but no single mechanism can explain all its pathological changes.AD is currently incurable and no effective treatment measures are available.So it is of prime importance to prevent the occurrence of AD.In the process of exploring the pathogenesis and treatment of AD, more and more attention is being paid to the role of diet and nutrition in the occurrence and development of AD.Mediterranean diet(MeDi)has been proved to have an unvarying role in the occurrence and development of Alzheimer's disease.This paper reviewed the relevant literatures and summarized the role of MeDi in AD, in order to provide the theoretical supports for dietary intervention and nutritional therapy in AD treatment.
