Iowa City (KWWL) - As the population ages, the number of dementia and Alzheimer's patients continues to rise, putting more memory-impaired drivers on the roads.
Researchers at the University of Iowa have created a combination of off-road cognitive and actual driving tests that they say can assess a person's ability to drive. Drivers with alzheimer's disease committed 27-percent more safety errors than those without Alzheimer's.
They also discovered patients who did better on the off-road tests made fewer driving mistakes.
