Abstract
This study investigated the relationship between cognitive ability and driving after stroke. Thirty-nine pre-stroke drivers were assessed using a battery of cognitive tests followed by a road test over a set route. Subjects were graded into Pass, Borderline of Fail categories on the basis of the road test. Cognitive test results were compared across grades of driving performance and significant differences were found on nine of the 23 measures. A discriminant function analysis identified 10 tests which together predicted the grading of 94% of subjects into Pass or Fail categories.
