Abstract

|
Objectives：The purpose of this study was to investigate the influence of sociodemographic factors on the results of each item of the 15-item Modified Boston Naming Test in the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Packet(BNT-KC) in a clinical sample. We also explored the usefulness of each item in BNT-KC for the diagnosis of Alzheimer’s disease(AD).
Methods：Data of BNT-KC from 261 outpatients aged over 60 years, including 150 diagnosed with AD and 111 with normal cognitive function, were analyzed. Logistic regression analyses were performed to investigate the association of age, gender, and education with the results of each item in BNT-KC controlling for cognitive function. The relationship between each item of BNT-KC and the diagnosis of AD were examined using logistic regression analyses controlling for age, gender, and education.
Results：Failing to answer ‘Mermaid’ was associated with low education level(≤6 years). Failing to answer ‘pomegranate’ was associated with the male gender, whereas failing to answer ‘compass’ or ‘dinosaur’ was associated with the female gender. Four items(‘hand’, ‘red pepper’, ‘wind-bell’, and ‘monk’s hat’) were not associated with the diagnosis of AD in this sample.
Conclusions：Several items of BNT-KC are affected by sociodemographic factors and some items are not useful for the diagnosis of AD. This finding will help to develop a revised edition of BNT-KC to improve the accuracy of dementia diagnosis.
