Mediterranean diet adherence is related to reduced probability of prodromal Parkinson's disease.

Background: The International Parkinson and Movement Disorder Society recently introduced a methodology for probability score calculation for prodromal PD.

Objectives: To assess the probability of prodromal PD in an older population and investigate its possible association with Mediterranean diet adherence.

Methods: Data from a population-based cohort study of older adults (HEllenic Longitudinal Investigation of Aging and Diet) in Greece were used.
