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

description: 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.
description: This study was an exploratory secondary data analysis and a
 cross-sectional study. It was approved by the Ethics Committee of Showa
 University (Approval No. 2023-111-B). Two datasets were used in this
 study. Data 1 were scores of the CogEvo provided by Total Brain Care CO.,
 Ltd (Data 1). Data 2 included 20 participants and these were the secondary
 data of the RCT “Effectiveness of an Application Software SoroTouch in
 Middle and advanced age people” (Data 2). 
 <strong>Data 1</strong> Data 1
 were secondary data obtained by Total Brain Care CO., Ltd. All
 participants conducted the CogEvo as part of preventive care services in
 10 municipalities in Japan and agreed to have their data used in the
 research before CogEvo was performed. The exclusion criteria were as
 follows: 1) age less than 40 or more than 100; 2) performing CogEvo for
 the second or later time; and 3) performing other than five basic tasks
 (“Flashing Lights,” “Follow the Order,” “Orientation,” “Route 99,” and
 “Same Shape”). The data were anonymized and included only the scores of
 the CogEvo, age, and sex because they were secondary data. These data were
 collected on a task-by-task basis, and it was not known which task was
 performed by each individual participant. In addition, some participants
 performed tasks other than the five basic tasks. Hence, the total scores
 from the five basic CogEvo tasks were unknown.
 <strong>Data 2</strong> Data 2
 were the baseline data of the RCT “Effectiveness of an Application
 Software SoroTouch in Middle and advanced age people”, and the
 participants were 20 individuals (6 men, 14 women) aged 42–79 years who
 were recruited from the participants of community-based activities for
 reducing the risk of dementia held by the Niyokatsu general incorporated
 association. They were different from the participants in Data 1. The
 participants had never been diagnosed with dementia nor MCI, and were able
 to come to the office of the general incorporated association alone.
 Cognitive function was evaluated using the CogEvo and the MoCA-J before
 the intervention in the RCT. We obtained the participants’ scores of the
 CogEvo and MoCA-J, and their demographic and clinical characteristics. The
 study population included 6 male and 14 female participants (mean age,
 63.5 ± 11.0 years; range, 42–79 years).

 [https://doi.org/10.5061/dryad.vdncjsz24](https://doi.org/10.5061/dryad.vdncjsz24) ## Description of the data and file structure The data comprises two Excel files. "Data 1" was secondary data of the CogEvo scores in the general public collected by Total Brain Care CO., Ltd. The Excel file shows the task performed by each participant, his/her score, and his/her age at the time. Unknown data are marked as N/A. "Data 2" was the secondary data from an RCT “Effectiveness of an Application Software SoroTouch in Middle and advanced age people”. In the Excel file, applicable data is marked as 1, while not applicable data is marked as 2. Age is represented in decades to ensure personal information protection. Body mass index (BMI) is described as low body weight if it is below 18.5, normal weight if it is between 18.5 and 25, and obesity if it is above 25. "same shape", "orientation", "flashing light", "route 99", " follow the order" columns indicate the score of CogEve. The "MoCA-J" column and the columns to the right of it indicate the total MoCA-J score and the scores of the sub-items. ## Sharing/Access information This data is associated with the following data sets: * [https://doi.org/10.5061/dryad.1ns1rn8zx](https://doi.org/10.5061/dryad.1ns1rn8zx)
