Progress on evaluation of dysphagia in patients with Parkinson′s disease / 中华神经科杂志

ABSTRACT

Parkinson′s disease (PD) is a common neurodegenerative disease. The prevalence of dysphagia in patients with PD is 16%-87%. Dysphagic patients show abnormalities in the oral, pharyngeal and esophageal phases of swallowing. The evaluation tools of dysphagia in patients with PD include instrumental assessment tools, non-instrumental objective assessment tools and subjective assessment tools. Videofluoroscopic study of swallowing and flexible endoscopic examination of swallowing are the gold standards for swallowing assessment in patients with PD; high-resolution manometry, tongue pressure measurement, surface electromyography and ultrasonography can be used as supplementary tests; the Swallowing Disturbance Questionnaire Scale, which is sensitive, specific, reliable and valid, is recommended as a screening tool.
