Researchers highlight the importance of caregivers having conversations with care recipients and healthcare professionals about driving.
The majority of older adults with cognitive impairment continue to drive, despite concerns raised by caregivers and others, according to a study conducted by Michigan Medicine in a South Texas community.
More than 600 adults over the age of 65 in Nueces County, Texas, were assessed. All of them had cognitive assessment scores indicating a likelihood of cognitive impairment.
The research showed that 61.4% of these cognitively impaired individuals were still active drivers. Furthermore, around one-third of all caregivers expressed concerns about their care recipients’ driving capabilities. The study’s findings are published in the Journal of the American Geriatrics Society.
Researcher Insights
“It is likely appropriate that some with mild cognitive impairment are still driving, but for some, it may not be,” said senior author Lewis B. Morgenstern, M.D., professor of neurology, neurosurgery and emergency medicine at University of Michigan Medical School and professor of epidemiology at the U-M School of Public Health.
“Patients and caregivers should discuss these issues with their health care providers and consider on the road driving evaluations to ensure safety.”
Cognitive Conditions and Driving
An estimated one in nine Americans aged 65 and older, totaling around 6.7 million people, are believed to live with Alzheimer’s disease. Millions more have related dementias.
These conditions can compromise neuropsychological and visual skills essential for safe driving. A 2017 review of motor vehicle crash risk found that dementia had medium to large effects on driving impairment and that people with dementia have an increased likelihood of failing a road test compared to those without the condition.
Driving Prevalence and Caregiver Concerns
The study initially aimed to compare the driving prevalence among older Latino and non-Latino white adults. No significant differences were found between these two groups. However, they discovered that the more cognitively impaired an individual was, the less likely they were to be driving.
Just over 35% of caregivers expressed concerns about their care recipient’s ability to drive safely. These concerns persisted even though many study participants voluntarily limited their driving and avoided hazardous conditions, like night-time or rainy weather.
The Importance of Early Conversations
Discussing driving capabilities with individuals who have cognitive impairment is challenging. The discussion is often fraught with concerns over the loss of autonomy and potential embarrassment. In addition, the cessation of driving can increase the workload of a caregiver.
However, researchers recommend initiating conversations about driving early on. This allows care recipients to understand and participate actively in the discussion.
“Close family may have discussions with aging loved ones about Advance Driving Directives,” Morgenstern said. “These are agreements between an aging person and a loved one about having conversations about driving cessation.”

In most of the US, it’s impossible to live on your own without automotive transportation, whether you drive, or someone drives for you. Giving that up, and moving to some sort of “home” is a hard pill to swallow.
Even in cities it’s hard to not drive, because of zoning. The idea of having residential areas, and separate commercial areas is ageist!
