Aged drivers with cognitive impairment run higher risk of collision: Study
According to a study most elderly people with cognitive impairment continue to drive despite worries voiced by carers and others. In Texas' Nueces County, more than 600 people over 65 with cognitive screening results that suggested possible impairment were examined by researchers.

Michigan [US], July 23 (ANI): According to a study most elderly people with cognitive impairment continue to drive despite worries voiced by carers and others.
In Texas' Nueces County, more than 600 people over 65 with cognitive screening results that suggested possible impairment were examined by researchers.
One-third of all carers were concerned about their care recipient's driving, and 61.4% of those with cognitive impairment were current drivers. The American Geriatrics Society Journal publishes the findings.
“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, MD, professor of neurology, neurosurgery and emergency medicine at the 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.”
Approximately one in nine Americans aged 65 and older, or 6.7 million people, are estimated to live with Alzheimer’s disease and millions more have related dementias.
These conditions may affect neuropsychological and visual skills that reduce the ability to drive safely. A 2017 review of motor vehicle crash risk found that dementia had medium to large effects on driving impairment and that people with dementia are more likely to fail a road test than those without.
Investigators initially set out to study the driving prevalence of older Latino and non-Latino white adults, finding no significant differences between the two populations. However, the more cognitive impairment any individual had, the less likely they were to be driving.
Just over 35 per cent of caregivers had concerns about their care recipient’s ability to drive safely, even though many study participants limited their total amount of driving and avoided driving at night or in the rain.
The discussions between caregivers and people with cognitive impairment about driving are difficult, with concerns over the loss of autonomy and potential embarrassment. When a person with cognitive impairment stops driving, that may also increase the workload of a caregiver.
Researchers say it’s best to start conversations surrounding driving earlier while the care recipient is able to understand and actively participate 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.” (ANI)
