Driving after traumatic brain injury

BACKGROUND AND OBJECTIVE Traumatic brain injury(TBI)and stroke are common causes of cognitive impairment in adults.As safe driving requires cognitive abilities that may be reduced after stroke or TBI,clinicians must often assess the ability of their patients to safely drive after such an injury.This study examined the neuropsychological testing used in return to drive assessments,and sought to develop standardized cutoff values for the likelihood of driving success.METHODS This retrospective study examined patients six to 20 months post-injury,all of whom had sustained a TBI or stroke.All underwent medical examination,neuropsyehologieal testing and a comprehensive on road assessment.A forward,stepwise,logistic regression analysis was used to test the predictive power of demographic,diagnostic and neuropsychological variables on on-road test results.
