Abstract:
Objective:To investigate the motor and non-motor symptoms and polysomnographic features in patients with rapid eye movement sleep behavior disorder (RBD), early Parkinson's disease (PD) with and without RBD.Methods:Patients with idiopathic RBD (IRBD) and early PD were collected from the clinics in West China Hospital of Sichuan University from August 2020 to May 2021.All the patients were divided into 3 groups including IRBD group (67 cases), PD with RBD (PD+ RBD) group (19 cases), and PD without RBD (PD-RBD) group (22 cases). Unified Parkinson's disease rating scale part 3 (UPDRS-Ⅲ), Hoehn-Yahr(H-Y) stage, Epworth sleepiness scale (ESS), REM sleep behavior disorder questionnaire-Hong Kong (RBDQ-HK), 17-item Hamilton depression scale(HAMD-17), mini-mental state examination(MMSE), Sniffin’Sticks olfactory function test, visual analogue scale (VAS), and scale for outcomes in Parkinson's disease-AUT(SCOPA-AUT) were used to assess the motor and non-motor symptoms including sleepiness, RBD, depression, cognitive function, olfactory function, pain and autonomic function respectively.All patients were performed to the polysomnography (PSG) examination.One-way ANOVA, Krukal-Wallis test, χ2 test and Fisher accurate test were used to analyze the data of motor and non-motor symptoms and sleep parameters among the 3 groups accordingly. Results:There were statistically significant differences in motor symptoms among the three groups ( F=57.009, P<0.05), and the scores of UPDRS Ⅲ and H-Y stage were higher in the PD+ /- RBD group than those in the IRBD group(both P<0.05). However, there was no significant difference in motor symptoms between PD+ RBD group and PD-RBD group ( P>0.05). There were no significant differences in the scores of ESS, MMSE, olfactory function test and VAS (all P>0.05). But the HAMD-17 score was significantly higher in the PD+ RBD group(2(1, 9)) than that in the IRBD group (0(0, 3)( P<0.05). The SCOPA-AUT scores of autonomic function were significant differences in the three groups, mainly in the digestive system, urinary system, and sexual function ( P<0.05). Notably, the IRBD group (8(4, 14)) and PD+ RBD group (11(7, 14)) had higher scores of SCOPA-AUT compared with PD-RBD group (4(4, 5.75)(all P<0.05), especially in the digestive dysfunction(all P<0.05). The PD+ RBD group(3.47±1.17) had higher scores of sexual function compared with IRBP group(1.78±0.60)( P<0.05), and the urinary system scores also higher than PD-RBD group( P<0.05). The PD-RBD group(21.30 (6.10, 34.00)/h) had a significantly higher oxygen desaturation index in REM sleep compared with that of IRBD group(5.90(2.70, 16.73)/h) ( P<0.05). Conclusions:Early PD with RBD has more severe non-motor symptoms, especially depression and autonomic dysfunction.RBD can be related with the earlier and more widely autonomic dysfunction.
