[Associations between chronotype, road accidents and polymorphisms in genes linked with biological clock and dopaminergic system].

Unlabelled: Public transport driving is a highly demanding activity requiring high skills and responsibility. Shift work, problems with regular sleep schedule negatively impact psychomotor reactions, cognitive functions and ability to react appropriately to the changing environment. For professional drivers all these factors may lead to the increased risk of a road accident.

[Polymorphisms in Sleep and Cognitive Function Related Genes are Associated with Vehicle Crash History in Shift Working Bus Drivers].

Bus driving is a highly responsible profession. It requires constant engagement of attention and cog- nitive resources as well as vigilance and resistance to disruption of sleep- rhythms. There is ongoing research of genetic correlates of these individual characteristics.
