Abstract

Sleep disorders are very common in advanced Parkinson’s disease (PD) and have a significant negative impact on the quality of life of patients. Questionnaire-based studies suggest that sleep quality might improve following levodopa–carbidopa intestinal gel (LCIG) infusion. The objective of this study was to evaluate the impact of LCIG infusion and subsequent oral medication changes on polysomnography (PSG) and sleep symptoms in advanced PD patients. Eleven PD patients underwent PSG at baseline and after 3.8 ± 1.2 months of LCIG treatment. LCIG infusion therapy was halted during PSG. Patients were assessed with the Unified-PD-rating-Scale and completed the PD-Sleep-Scale-version-2 (PDSS-2), the Epworth Sleepiness Scale and the RBD single question. Subjective sleep quality improved in all patients. PSG showed a reduction of the number of awakenings in sleep, a trend towards a lower apnea–hypopnea index and no change in sleep latency, total sleep time and sleep efficiency. There was a positive correlation between the number of awakenings and PDSS-2 scores for “difficulty staying asleep”, “muscle cramps of arms or legs” and “urge to move arms or legs”. Motor complications and activities of daily living improved with LCIG. Subjective sleep quality improved significantly and the PSG study showed a less fragmented sleep pattern in advanced PD patients treated with LCIG infusion.
