Enteral Nutrition in Idiopathic Parkinson's Disease and Atypical Parkinsonism: A Systematic Review

This systematic review examined 16 studies investigating enteral nutrition's effects on survival and complications in Parkinson's disease and atypical parkinsonism, finding moderate-to-high risk of bias across all included studies. Despite aspiration pneumonia occurring in ~40% of parkinsonism patients after enteral feeding, evidence remains insufficient to conclusively demonstrate improved survival, with weighted median survival around 1.35-1.49 years post-gastrostomy.
