Correlation between high cholinergic pathway signal and cognitive function in patients with Parkin-son disease accompanied with sleep disorder
Objective To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD)accompanied with sleep disorder.Methods PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group(PD-SD group)(n=56)and PD without sleep disorder group(PD-NSD group)(n=41)according to the Parkinson's disease sleep scale(PDSS)score.All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS,Hoehn-Yahr(H-Y),Montreal cognitive assessment scale(MoCA),and cholin-ergic pathways hyper intensities scale(CHIPS).The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test,Spearman correlation analysis,and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software.Results(1)The MoCA score of the PD-SD group(22.00(5.00))was lower than that of the PD-NSD group(26.00(5.00))(Z=-3.830,P＜0.05).The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule:12.00(8.00),0(8.00),the total score of the high external capsule:12.00(2.00),6.00(9.00),the total score of the radial crown:8.00(0),4.00(4.00),the total score of the centrum semiovale:3.00(4.00),0(2.00),the total score of the right side:16.00(9.00),5.00(10.00),the total score of the left side:17.00(6.00),7.00(9.00),the total score of CHIPS:32.00(14.00),14.00(20.00))(Z=-5.081,-5.873,-4.933,-3.211,-5.562,-6.232,-5.995,all P＜0.05).(2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that,the total score of the low external capsule(r=-0.286),the total score of the centrum semiovale(r=-0.307),the total score of the right side(r=-0.376),the total score of the left side(r=-0.284)and the total score of CHIPS(r=-0.349)were negatively correlated with MoCA(all P＜0.05).(3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale,low inner capsule,right and left leukodystrophy were not influence fac-tors for cognitive impairment(all P＞0.05).Conclusion PD patients with sleep disorders have lower cog-nitive function scores,higher CHIPS scores,and significant changes in white matter lesions compared to those without sleep disorders.In PD patients with sleep disorders,the higher the CHIPS score,the lower the cogni-tive function score,and the more significant the rate of cognitive impairment occurrence and development.
