Background
Autonomic symptoms and sleep disorders are common non-motor symptoms of Parkinson disease (PD), which are correlated with poor quality of life for patients.
Purpose
To assess the frequency of autonomic symptoms in a consecutive series of PD patients and to correlate them with other motor and non-motor symptoms.
Methods
All consecutive non-demented PD patients who underwent an extensive evaluation including Hoehn and Yahr staging, Unified Parkinson’s Disease Rating Scale, Beck’s Depression Inventory, Neuropsychiatric Inventory, PDQ-39 Scale, the Parkinson’s diseases Sleep Scale, the Epworth Sleepiness Scale and SCOPA-AUT scale were enrolled. Comorbidity has been also considered. Supine to standing position blood pressure and cardiac frequency changes were also measured.
Results
135 PD patients were included (mean age at interview 67.7; mean disease duration: 5.3 years). Patients were stratified according to mean SCOPA-AUT scale score (13.1). Those with higher SCOPA-AUT scale score were significantly older, had longer disease duration, worse disease stage, worse quality of sleep, were more severely affected, and were also taking a higher dosage of levodopa. At multivariate analysis, older age, longer disease duration, and worse quality of sleep were independently associated with higher SCOPA-AUT scale scores.
Conclusions
Our results remark the role of autonomic symptoms in PD. In our patient population, characterized by mild to moderate disease severity, most of the patients complained of autonomic nervous system involvement (84 %). A significant association between autonomic symptoms and sleep disorders was also observed.
