Abstract:
Objective To objectively analyze the manifestation of sleep disorders in patients with Parkinson' s disease (PD) using polysomnogram (PSG) and multiple sleep latency test (MSLT). Method Twenty-six patients (PD group)with PD and 31 controls without CNS diseases( control group) underwent all night ambulatory video-polysomnographic monitoring and MSLT on the next day. Sleep architecture, mean sleep latency,sleep onset rapid eye movement (REM) periods(SOREMPs) and sleep attacks(Sas) of the two groups were analyzed. Results When compared to the controls, percentage of NREM stage 2 sleep,percentage of REM sleep, mean sleep latency in the PD patient group were significantly decreased (32.8% ±13.1% vs40.2% ±9.1%,t = -2.515;8.6% ±5.3% vs 11.5% ±5.1%,t = -2.054;(9.6 ± 4. 4) min vs ( 15.7 ± 3. 1 ) min, t = - 6. 1 64, all P ＜ 0. 05 ), while arousal index was significantly increased ( (41.8 ± 32. 1 )/h vs ( 28.6 ± 1 1. 0 )/h, t = 2. 151, P ＜ 0. 05 ). The prevalence of excessive daytime sleepiness (EDS; 7/26, 26. 9% ) was higher in the PD patient group than in the controls (1/31,3. 2%; ×2 =4. 764,P＜0. 05). Multivariate linear regression analysis showed that after adjusting for sleep efficiency, apnea hypopnea index, arousal index, decreasing mean sleep latency in PD patients was significantly associated with both age( β = -0. 328) and levodopa equivalents( β = -0. 008; t = -2. 829,-2. 352,all P ＜ 0.05). SOREMPs occurred in 5 of 26 (19.2%) PD patients and Sas occurred in 3 ( 11.5% ) PD patients but did not occur in the controls. Conclusion Changes in sleep architectures and EDS are more common in PD patients. Physicians should be highly vigilant in recognizing Sas, which are uncommon in PD patients.
