[Driving and cognitive impairment: how best to anticipate?]

Driving requires integrating multiple motor, sensory, and cognitive skills. As people age, cognition becomes increasingly vulnerable due to impairment and dementia. Older drivers suffering from dementia, even at an early stage, have been shown to be significantly more likely to develop unsafe driving. Primary care physicians have the difficult task to assess these persons' driving capacity. This paper briefly describes the consequences of altered cognition on driving capacity and proposes an algorithm to address this challenge.
