We conclude that(1)the existing evidence suggests that AD patients who drive present a slightly increased risk for crashes compared with drivers of all ages but a lower risk than young unimpaired drivers,especially males.(2)During the first 2 to 3 years after the onset of AD,the magnitude of risk of crashes is well within the accepted risk for other registered drivers.(3)There is marked variability in the degree of disability due to AD and its rate of progression.Because of this,direct tests of driving competence-rather than the diagnosis of AD per se-should be considered as the criterion for continued licensure to drive,with sufficiently frequent retesting to anticipate the expected decline over years. |
