Consensus practice recommendations for management of gastrointestinal dysfunction in Parkinson disease
This expert consensus document provides evidence-based clinical guidance on screening, diagnosis, and treatment of gastrointestinal dysfunction in Parkinson disease, a common non-motor symptom that can precede motor symptoms and significantly impact quality of life. Recommendations are organized by anatomical segments (oral cavity, esophagus, stomach, small intestine, colon) based on a modified Delphi panel approach involving movement disorder neurologists and gastroenterologists.
