Analysis of repeatable battery for the assessment of neuropsychological status (RBANS) in first-episode depression patients

Abstract

Objective To investigate the damaging traits of cognitive function in first episode depression patients with the assessment of neuropsychological status ( RBANS) and Stroop Color-word Test. Methods Two hundred and thirty first-episode depression patients as experimental group and one hundred and seventy-eight health person as control were evaluated separately by repeatable battery for the RBANS and Stroop Color-word Test. Results In Stroop Color-word Test,the time required for completing the words,color,double-word,two-color in depression patients ( (14.37 ±6.65)s,(21. 58 ±8. 70) s,( 16. 56 ±8. 23)s, (37. 88 ± 13. 67) s) were longer than the control group ((12.38 ±3.34)s, (18.01 ±5.51) s, (14. 17 ±4. 37) s, (32. 87 ± 10.28) s). The difference between the two groups was found in cognitive function in first episode depression patients (P ＜ 0.05). The scores of color interference and meaning interference were no difference between the two groups (P＞0.05) . The patients'scores of the RBANS test in all items( (72.19 ± 17.22), (80.89 ± 15.29), (82.00 ± 16.37) , (98.74 ± 17.01) ,(82.09 ± 14.62) )were significantly poorer than those in healthy controls. Compared with control group, scores of the scales were significant difference between two groups. Pearson correlation analysis showed that RBANS total score and five factors had no correlation with HAMD total score and factors. It positively correlated with education level (P＜0.05) ,but not with sex (P＞0.05). Immediate memory,verbal function,delayed memory in five factors and RBANS total score negatively correlated with age and course of disease respectively, but breadth of vision,attention were not did(P＜0.05). Conclusion First-episode depression patients suffer from more serious and comprehensive damage of cognitive function such as memory,attention,executive function.
