ABSTRACT

Objective To investigate the applicability of Stroop color-word test in Chinese eldly patients with sub-jective cognitive impairment. Methods 36 patients with subjective cognitive impairment and 35 normal elders,all accepted general information questionaire( including age,gender,education,ect) ,Chinese version Stroop color-word test,background neuropsychological tests(MMSE,ADL,GDS,ect). Analysis of indicators included the number of errors,average response,Stroop interference effects ( SIE)-Time difference of the Color inconsistencies and consist-ent with the meaning of words. At last we analyse relationship between CWT results and age,education,et al. Re-sults There were no significant differences in neuropsychological tests. Compared with normal subjects,subjective cognitive impairment subjects spent more time and made more errors in doing this task. They made statistical signifi-cance. The linear regression analysis between reaction time, the number of errors and overall cognitive function ( MMSE) , age, memory ( digit span, delayed recall) showedthe numbers of errors and the average response time had significant positive correlation with age. SIE of SCI was significantly longer than the normal control, the differ-ence was significant (P<0. 05). And it had no significant correlation with age, overall cognitive function and mem-ory and other related inspection. Conclusion Stroop color-word test has a certain sensitivity in recognition of sub-jective cognitive impairment elders.
