Objective To study the relationship between plasma neurodegenerative protein level and non-motor symptoms(NMS)in PD patients.Methods Eighty-four PD patients served as a PD group and 54age-matched persons undergoing physical examination served as a control group. The NMS of PD patients were assessed according to the HAMD scale.The plasma levels of tau,p-tau181,Aβ-42andα-syn were measured by ELISA and analyzed by Spearman correlation analysis and binary logistic regression analysis respectively.Results The FSS score and plasmaα-syn level were significantly higher while the plasma Aβ-42level was significantly lower in PD group than in control group(3.22±1.68 vs 1.89±1.16,P=0.000;320.00±64.91ng/L vs 277.78±52.75ng/L,P=0.000;267.61±77.75ng/L vs 321.80±49.41ng/L,P=0.001).No significant difference was detected in plasma tau and p-tau181levels between the two groups(P＞0.05).The plasmaα-syn level was positively related with the FSS score(r=0.237,P=0.030)and was an influencing factor of FSS(OR=1.019,95％CI:1.006-1.032,P=0.004).Conclusion Plasma neurodegenerative protein level is related with NMS and plasmaα-syn level is a peripheral biomarker for fatigue in PD patients.
