Systematic Assessment of Laryngopharyngeal Function in Patients With Neurodegenerative Diseases

This is a non-interventional observational study designed to systematically record the results of routine laryngeal examinations and specific characteristics of dysphagia in patients with neurodegenerative disorders. The results of a fiberoptic / flexible endoscopic evaluation of swallowing (FEES) while performing a structured task protocol will be recorded. If available, laryngeal electromyography (EMG) results will also be recorded. In addition to the examination results, demographic and disease-specific data are collected, and two questionnaires, the Swallowing Disturbance Questionnaire for Parkinson's Disease (SDQ-PD) and the swallowing specific Quality Of Life Questionnaire (SWALQOL), are administered.
