Abstract
Oropharyngeal and esophageal dysphagia are a frequent, but seldom diagnosed symptom of Parkinson's disease (PD). More than 80 % of patients with PD develop dysphagia during the course of their disease leading to a reduced quality of life, complicated medication intake, malnutrition and aspiration pneumonia, which is a major cause of death in PD. The underlying pathophysiology is poorly understood. Impaired dopaminergic and non-dopaminergic mechanisms of the cortical swallowing network as well as peripheral neuromuscular involvement have been suggested to contribute to its multifactorial genesis. Diagnostic screening methods include PD-specific questionnaires and a modified water test. Fiber optic endoscopic evaluation of swallowing (FEES) and videofluoroscopic swallowing study (VFSS), which complement each other, are the gold standard for evaluation of PD-related dysphagia. For evaluation of esophageal dysphagia, the high-resolution manometry (HRM) may be a helpful tool. In addition to dysphagia-specific treatment by speech and language therapists (SLTs), optimized dopaminergic medication is a meaningful therapeutic option. A promising novel method is intensive training of expiratory muscle strength (EMST). Deep brain stimulation does not seem to have a clinically relevant effect on swallowing function in PD.
