The hallmark of Parkinson’s disease (PD) is the accumulation of alpha-synuclein (AS) aggregates. Prior to the central nervous system involvement, PD establishes itself in the gut as a result of the complex interplay between microbiota, the host’s immune/neural systems and increased intestinal permeability. Inflammatory Bowel Disease (IBD) patients...

A growing body of evidence suggests that nutritional status may play an important role in the development and course of Parkinson’s disease (PD). Nutritional status is known to influence PD motor and non-motor features and is in turn influenced by disease duration and severity. A proper nutritional status assessment and intervention should be incor...
