- Abstract: Objective To investigate the predictive value of National Institutes of Health Stroke Scale(NIHSS)score,serum brain-derived neurotrophic factor(BDNF)and interleukin-6(IL-6)in post-stroke depression(PSD).Methods A total of 180 patients with stroke were selected and divided into the PSD group(n=80,HAMD≥8 points)and the non-PSD(NPSD)group(n=100,HAMD＜8 points),according to HAMD score at 3 months after stroke.The basic information,NIHSS score,serum BDNF and IL-6 were compared between the two groups.The influencing factors of PSD were analyzed by Logistic regression method.Receiver operating characteristic(ROC)curves were plotted to evaluate the predictive value of NIHSS score,serum BDNF and IL-6 for PSD.Results Compared with the NPSD grope,low density lipoprotein cholesterol(LDL-C)and serum BDNF level were significantly lower,NIHSS score and serum IL-6 level were significantly increased in the PSD group(P＜0.05).Results of Logistic regression analysis showed that increased NIHSS score and serum IL-6 were risk factors for PSD,and increased serum BDNF was the protective factor in patents with PSD(P＜0.05).The area under curve(AUC)of NIHSS score,serum BDNF and IL-6 and their combination prediction of PSD were 0.762,0.746,0.796 and 0.839,respectively.The sensitivity of the combined prediction was 86.0%and a specificity was 95.0%.Conclusion Compared with NPSD patients,the NIHSS score and serum IL-6 level are increased,and the serum BDNF level is decreased in patients with PSD.The combination of all three has a high predictive value for patients of PSD.
