Data from: Evaluating the usefulness of CogEvo for detecting early neurocognitive decline in healthy middle-aged and elderly in Japan

This study aimed to obtain standard scores of the CogEvo (Total Brain Care
CO., Ltd., Kobe, Japan), which is a computer-based cognitive function
assessment tool, for healthy middle-aged and older people and to
investigate the usefulness of the CogEvo in detecting the group below the
MoCA-J reference point. This study was an exploratory secondary data
analysis and a cross-sectional study. Two datasets were used in this
study; Data 1 was secondary data of the CogEvo scores in the general
public collected by Total Brain Care CO., Ltd. This big data included 726
to 1421 participants, varying in number for each CogEvo task. Data 2 was
the secondary data from a RCT including the CogEvo scores, the MoCA-J
scores for the 20 participants. In data 1, all tasks showed statistically
significant differences between age groups. Multiple comparisons showing
significantly lower scores in the 60s compared to the 40s only in
“Flashing light” task, although all other task scores were significantly
lower than those in their 70s or 80s. Then, the first quartile of the
CogEvo task scores for each age group in Data 1 was determined as cut-off
points in order to investigate CogEvo’s sensitivity and specificity for
detecting MoCA-J≤ 25 group in Data 2. The sensitivity and specificity were
66.7% and 63.6%, respectively, and these were not so high. However,
"Flashing light" scores began to decline in the 60s, suggesting
that the CogEvo may be useful for detecting age-related neuromotor
cognitive decline in healthy middle-aged and older adults.
