Neuropsychological aspects of driving characteristics.

Brain injury often causes impairments of cognitive functions, which may affect driving performance. The question of whether the brain-injured patient can resume car driving or not generally comes up during rehabilitation. The medical clinical examination, covering neurological status, screening of cognitive functions, and affective state, is insufficient in assessing relevant functions required for driving performance. A neuropsychological assessment and a driving test are additional parts of the driving assessment besides the medical examination. In this paper, neuropsychological test results and driving test results from four patients with brain injury are presented. The paper demonstrates the complementary value of neuropsychological assessment and a driving test: the relevance of cognitive factors for interpretation of driving problems, but also the relevance of a driving test to show compensatory capacity in some drivers with brain injury. Thus, collaboration between medical, neuropsychological and driving expertise can promote and deepen the total assessment of driving performance after brain injury.
