Mild Alzheimer's Patients Can Drive Safely
"I don't think this population is representative of all drivers with
dementia. I think it was a rather robust group who was conscious of the fact
that they were driving with dementia and probably would need to quit,"
Foley tells WebMD. Foley agrees that it's possible to drive safely with
Alzheimer's disease, but not for long.
"For me, a patient with Alzheimer's disease is an accident on the way to
happen. Well, how do you prevent that ...? You have the person stop
driving," says Foley. Morris acknowledges that those in the study may
represent a pro-driving bias, but he says more research needs to be done to see
how the positive finding applies to a larger population of Alzheimer's
The study does show that those with DAT tended to more often be involved in
crashes where they were at fault or where injuries were involved. "What
particular cognitive abilities need to be affected, how severely, and whether
drivers with dementia are more likely to be involved in at-fault or injurious
crashes ... remain to be determined," writes accompanying editorial author
Richard Marottoli, MD, of the VA Connecticut Healthcare System.
- The rate of dementia of the Alzheimer's type doubles every five years in
the population over age 65.
- A new study shows that patients with this mild form of Alzheimer's disease
can drive just as safely as their healthy counterparts.
- Critics say the study is flawed because individuals likely to have the best
driving records were selected for the study.
