Voice and swallowing impairments are common in movement disorders, but their effect on patients’ quality of life is not well known. This study was conducted to determine the onset and prevalence of patient-reported dysphonia and dysphagia symptoms in Parkinson's disease (PD), dystonia, Atypical Parkinsonian Syndromes (APS), and Essential Tremor (ET). Patients referred to a movement disorders clinic in a tertiary care academic medical center completed validated voice and swallowing specific Quality of Life (QOL)questionnaires: Voice Handicap Index-10 (VHI-10)and Eating Assessment Tool-10 (EAT-10). Patient demographics and clinical data were also collected. Two hundred and sixty-eight patients (males = 150, females = 118)completed the questionnaires (n was PD = 103, APS = 30, ET = 56, dystonia = 32, other = 47). Prevalence of patient-reported dysphagia symptoms was significantly higher in APS (63%)than PD (26%), ET (25%), and dystonia (31%). Prevalence of patient-reported dysphonia symptoms was significantly lower in ET (14%)compared to PD (34%)and APS (43%). Disease duration was shorter in PD and APS compared to ET and dystonia (p < 0.05)before reporting clinically significant dysphonia and dysphagia symptoms indicating an earlier onset of these symptoms. There were significant positive correlations between VHI-10 and EAT-10 scores and disease severity, as indicated by Unified Parkinson's Disease motor scores (p < 0.0001)and modified Fahn-Tolosa-Marin Tremor Rating sub-scores (p = 0.0013). Patient-reported dysphonia and dysphagia symptoms were present in one fourth of patients with PD, ET, dystonia, and almost two thirds in APS. Patient-reported QOL measures, such as VHI-10 and EAT-10, can help screen movement disorder patients for dysphonia and dysphagia symptoms.
