Objectives:The 15-item Modified Boston Naming Test in CERAD-K(BNT-KC) is composed of line drawings and has the possibility of lacking accuracy due to visual perceptual ambiguity of the stimulation. In order to minimize this, we developed a revised version of BNT-KC composed of photographic stimulation of the same contents, and compared the diagnostic accuracy of it with the original version.
Methods:Pictures of the same objects in the original BNT-KC were taken by camera or downloaded from the internet. One hundred and eighty-four elderly, who visited the memory clinic for the diagnosis of dementia(95 Alzheimer’s dementia(AD), 89 normal), completed both the versions of BNT-KC. Difference in the total score was compared using paired t-test. To verify whether there is a difference with the matched pairs of items, the McNemar’s test was carried out. Area under a receiver operating characteristic curve(AUC) was obtained to compare the performance of each test.
Results:There was a significant difference between the total score of the original version and the photographic version of BNT-KC(t=14.26, p<0.001). Eight items, “Cobweb,” “Balloon,” “Bat,” “Traffic light,” “Acorn,” “Pomegranate,” “Funnel,” and “Monk’s hat,” demonstrated significant differences in the McNemar’s test after the Bonferroni correction(p<0.003). AUCs for the diagnosis of AD in the original and photographic versions were 0.696 and 0.705, respectively. AUCs for the identification of moderate to severe AD(CDR 2 or higher) from others were 0.784 for the original version and 0.808 for the photographic version.
Conclusion:Characteristics of visual perceptual stimuli influenced the diagnostic accuracy of BNT-KC, especially in the identification of patients with moderate to severe AD. Revision of BNT-KC is required to enhance the diagnostic accuracy for dementia.
