Abstract:
Objective:The purpose of this study was to verify the validity and reliability of Korean elderly by translating the Hayling Test, a test that measures semantic inhibition ability among executive functions.
Methods:Total 91 participants were recruited in accordance with inclusion criteria and exclusion criteria for each group. Within them, 34 were normal from Dongjak-gu, Seoul, 29 were mild cognitive impairment (MCI) from clinics located in Seoul, and 28were Alzheimer’s disease (AD) from clinics located in Seoul, respectively. The one-way analysis of covariance, the Bonferroni veri-fication, the receiver operating characteristic (ROC) curve analysis, and the Brain Imaging analysis of voxel-based morphometrywere conducted in order to compare and analyze performance of demographics characteristics of each group, Hayling Test results, and The Continuous Performance Test-X (CPTX) results.
Results:The comparison analysis showed the Hayling Test is more valid methodology than the CPTX test in discriminating nor-mal, MCI, and AD. Furthermore, ROC curves between normal and AD groups also demonstrated higher sensitivity (88%) and specificity (73%) of Hayling Test, and confirmed its diagnostic validity. In line with the above, brain imaging analysis displays sig-nificant positive correlation between temporal & frontal brain regions through the Hayling Test scores, however, this correlationwas not found for CPTX.
Conclusion:It is expected that the Haling Test, which measures language inhibition function, can be used simply and usefully in diagnosing dementia.
