“…Answers to the following questions from an online survey of 2,000 Japanese people aged 40 and older who had a family member (also aged ≥40) classified as a person who needs support (but who did not yet require long‐term care) under the universal long‐term care insurance program in Japan were analyzed …”

“…Of the 2,000 individuals designated as needing support, 72.9% (n = 1,457) were female; the average age of those who needed support was 83.0 . Of all the persons designated as needing support, 268 held a valid driving license (n = 272 if including those hospitalized or institutionalized), and 92 of these 268 license holders were still driving as of this study.…”

The purpose of this study was to investigate the effects on prefrontal cortex brain activity when participants attempted to stop a car accurately at a stop line when driving at different speeds using functional near‐infrared spectroscopy (fNIRS). Twenty healthy subjects with driving experience drove their own cars for a distance of 60 m five times each at their own pace or as fast as possible. The variation in the distance between the stop line and the car was not significantly different between the self‐paced and high‐speed tasks. However, oxygenated hemoglobin concentration in the prefrontal cortex was significantly higher in the high‐speed task than in the self‐paced task. These findings suggest that driving at high speed requires more divided attention than driving at self‐paced speed, even though the participants were able to stop the car at the same distance from the target. This study shows the advantages and usefulness of fNIRS .

“…As the number of older drivers and their share of MVCs are increasing in Japan and western countries, concerns have been raised about the safety of older drivers and licensing for them 1–3. To allow license renewal for older drivers, many countries use an age-based screening in which drivers are assessed from a certain age for their fitness to drive through road tests, knowledge tests, vision tests, medical assessment and/or in-person renewal 4.…”

Effect of a cognitive test at license renewal for older drivers on their crash risk in Japan

ObjectiveTo evaluate the effect of adding a cognitive test to a license renewal procedure for drivers aged 75 years or older in reducing their motor vehicle collisions (MVCs). The test has been obligatory since June 2009.MethodsUsing monthly police-reported national data on MVCs from January 2005 through December 2016, we calculated the rates of MVCs per licensed driver-year by sex and age group (70–74, 75–79, 80–84 and 85 years or older) for each month together with the ratios of MVC rates of drivers in the three oldest age groups (which are subject to the test) to those of the 70–74 years group (not subject to the test) to control for extraneous factors affecting MVCs over the study period. Then, we conducted an interrupted time-series analysis by regressing the rate ratio stratified by sex and age group on the number of months from January 2005, June 2009 (when the cognitive test was introduced to a license renewal procedure) and June 2012 (when all drivers subject to the test have taken it at least once).ResultsThe rates showed a longitudinal decrease in male and female drivers over the study period without any apparent effects of the introduction of the cognitive test while no significant decrease was observed in the rate ratios after the introduction of the cognitive test.ConclusionsThere were no clear safety benefits of the cognitive test for drivers aged 75 years or older to reduce their MVCs.
