Alzheimer's disease (AD) is the leading cause of dementia in Western countries, and its prevalence is increasing as society becomes more long-lived. It's critical to look into elements that may be protective or impact the progression of Alzheimer's disease in order to intervene and lessen the incidence and advancement of the disease. The goal of this study was to conduct a systematic review and meta-analysis to see how a better adherence to the Mediterranean diet (MD) affects mild cognitive impairment (MCI) and Alzheimer's disease (AD).
