Decrease in cognitive function is known to be the main cause of driving cessation in old age but the same has not been clearly established in young adults. Previous research has implicated a variety of psychological factors related to fear of driving in young adults. Present study focuses on the measure of cognitive skills in such individuals who avoid driving in spite of an opportunity and necessity to do so. Cognitive function tests for two domains – speed and attention were performed in young female non drivers and drivers. Our results show a highly significant decrease in cognitive ability (P<0.05) in non drivers compared to the drivers. Our study indicates that decreased cognitive functions may be the main cause of cessation of driving seen in small but significant group of population.
