RESUMEN

Objective:To explore the diagnostic value of auditory verbal learning test-Huashan version(AVLT-H)of memo-ry impairment in patients with subjective cognitive decline(SCD)and mild cognitive impairment(MCI). Method:According to the inclusion criteria,the recruited elderly were screened and divided into three groups:normal cognition(NC),SCD and MCI group.The neuropsychological tests including mini-mental state exami-nation(MMSE),Montreal cognitive assessment-Beijing version(MOCA-BJ)and AVLT-H were completed af-ter inclusion.The scores of MMSE,MoCA-B,AVLT-N2,N3,N4,N5,N6 and N7 were recorded and analyzed. Result:There were significant differences in the scores of MMSE,MoCA and AVLT-H among the three groups(P＜0.0167).The adjusted Bonferroni test was used to detect significant differences in post-hoc comparison.There were significant difference in MMSE and MoCA scores between SCD and NC(P＜0.001)and between MCI and NC(P＜0.001).However,no significant difference between MCI and SCD was found.There were sig-nificant difference in N1 score between MCI and NC(P=0.013)and between MCI and SCD(P=0.001),but there was no significant difference between SCD and NC.There were significant difference in AVLT-N2,N3,N4,N5,N6 and N7 scores between MCI and NC(P＜0.001)and between MCI and SCD(P＜0.001),but there was no significant difference between SCD and NC.The area under the curve of MMSE,MoCA and AVLT-H scores were examined using NC group and SCD group as state variables,respectively.For differentiat-ing MCI and SCD,eAVLT-H scores had a larger area under the curve with higher sensitivity and specificity,N1 and N7 had the highest sensitivity.For distinguishing MCI from NC,AVLT-H and MoCA scores had a larger area under the curve with higher sensitivity and specificity,N4,N6 and N7 had the highest sensitivity. Conclusion:AVLT-H,combined with MMSE and MoCA,can improve the defining diagnostic sensitivity of MCI and SCD from normal cognition.It is recommended to routinely use AVLT-H in a routine assessment for MCI and SCD patients.
