Abstract
PURPOSE: Drooling is a common symptom of neurodegenerative diseases. We aimed to explore the frequency of drooling and its relationship to clinical features in a relatively large cohort of Chinese patients with multiple system atrophy (MSA). METHODS: We conducted a cross-sectional survey of 143 patients with MSA. Patients with drooling were identified as those with a score ≥ 1 on item 6 of the Unified Parkinson's Disease Rating Scale. Additional scales were used to rate daily functionality, neurologic and cognitive capabilities, levels of anxiety and depression, and sleep quality. These results were compared between patients with and without drooling. RESULTS: The frequency of drooling in this cohort was 59.4% (85/143). Drooling was associated with significantly poorer scores on the Unified MSA Rating Scale (subscore I, subscore II, subscore IV, total score), Pittsburgh Sleep Quality Index, Hamilton Depression Scale, Hamilton Anxiety Scale, and Mini-Mental State Examination. After adjusting for confounders, regression analysis identified two independent risk factors for drooling: parkinsonism-associated MSA (OR 2.54, 95% CI 1.15-5.65) and hypomimia (OR 3.18, 95% CI 1.32-7.68). CONCLUSIONS: Drooling is relatively common among Chinese MSA patients, and parkinsonism-associated MSA and hypomimia appear to be independent risk factors for drooling. The severity of this symptom correlates with the presence of severe motor symptoms, anxiety, depression, and sleep disorders.
