Abstract
Parkinson's disease (PD) patients suffer from xerostomia, but limited information exists regarding associations with dysphagia, drooling, daily habits, PD characteristics, or possible circadian rhythms. A questionnaire was administered, including (a) clinical characteristics (comorbidities, prescribed medications, levodopa equivalent daily dose [LEDD], disease duration); (b) self-assessment of dysphagia, xerostomia, drooling (10-cm visual analogue scale [VAS]); (c) 24-hr diary of motor impairment, dyskinesia, xerostomia, dysphagia, drooling, daily habits. Of 75 PD patients who completed the study, 67% reported dysphagia (mean ± standard deviation VAS 4 ± 2), 76% drooling (5 ± 2), 77% xerostomia (5 ± 2). Xerostomia was associated with comorbidities (p = 0.021) and smoking (p = 0.010) and affected by tremor (p = 0.003), dyskinesia (p = 0.010), dysphagia (p < 0.001), food intake (p = 0.005), sleep (p = 0.011), age (p = 0.018), medication intake (p = 0.063), LEDD (p = 0.052), daytime (p = 0.075), disease duration (p = 0.004). Xerostomia peaked at 9 a.m. and 9 p.m. PD patients suffer from xerostomia, dysphagia, and drooling. Subjective dysphagia is associated with drooling and xerostomia, but drooling prevalence or intensity does no...Continue Reading
