Abstract:
Objective To investigate the relationships between the clinical and subclinical REM sleep behavior disorder(sRBD)and the cognitive function in patients with PD. Methods We enrolled 53 patients with PD from the Second Affiliated Hospital of Nanchang University. The age ,gender and education level of each patient were recorded. Patients with dementia were excluded. The correlative scales were assessed by the form of face to face,including Montreal cognitive function score(MoCA),Unified Parkinson Disease Rating Scale(UPDRS), Parkinson Disease Sleep Scale (PDSS) and so on. The sleep quality was assessed by polysomnography(PSG), meanwhile PD patients were divided into the RBD group(PD-RBD),the subclinical RBD group(PD-sRBD)and the normal REM group(PD-REM)based on the polysomnography. The cognitive function was compared among the three groups. Results (1)MoCA score of PD patients in the RBD group was lower than that in the normal REM group(P = 0.032.(2)No significant difference was observed in the cognitive function between the sRBD group and the normal REM group.(3)Length of morbidity of PD patients with RBD was longer than that of PD patients with sRBD(P=0.021). Conclusions The presence of RBD may be an important relative factor for the develop-ment of cognitive dysfunction in PD patients. We haven′t detected that the subclinical RBD was associated with the cognitive dysfunction in patients with PD. It is not clear whether the subclinical RBD in PD patients develops to RBD in all patients,which needs further investigation.
