Investigation into the safety of driving by individuals with higher brain dysfunction

Dangerous driving by drivers with diseases or disabilities such as dementia, epilepsy, or higher brain dysfunction is viewed as a problem In Worldwide. Given that the majority of such cases of dangerous driving are caused by impairments to cognitive function resulting from these conditions, there is an urgent need to create systems to detect drivers with cognitive functional disability and develop criteria for safe resumption of driving. Because driving would understandably be extremely dangerous for people with higher brain dysfunction, particularly in cases of attention dysfunction, we first examined the correlation between the Clinical Assessment of Attention (CAT), a theoretical task offering an index of attention function, and the cathode ray tube (CRT) driving aptitude test. We then examined correlations between CRT total score and CRT sub-scores. Only the time required for the position Stroop test had a moderate correlation (r = -0.43, p < 0.01) with CRT total score. Correlations between CRT total score and sub-scores relating to reaction speed showed a strong correlation. Other than reaction speed, items with significant moderate to strong correlations were also seen in the maintenance of moderate mental tension, attention distribution and situation processing skill. The present results show a correlation between CAT score and CRT total score, indicating that CRT total score places relative weights on speed of information processing and suppression of stereotypes, representing a very meaningful result. doi:10.11482/KMJ-E41(2)71 (Accepted on October 27, 2015)
