A recent study reveals that older adults with major depressive disorder (MDD) tend to drive in riskier ways compared to those without the condition.
Published on December 30 in JAMA Network Open, the research highlights important differences in driving habits between these groups, shedding light on how mental health can influence day-to-day activities like driving.
The study, led by Dr. Ganesh M. Babulal from Washington University in St. Louis, focused on a group of 395 adults aged 65 and older. Among them, 85 had been diagnosed with MDD, while 310 did not have the condition.
To understand their driving patterns, researchers used a commercial device to track their everyday driving behaviors over time. This approach allowed the team to observe natural driving habits rather than relying on self-reports or simulations.
From the start, adults with MDD showed clear differences from those without depression. They experienced more severe depressive symptoms and were more likely to have additional health conditions. They also tended to take more medications, including antidepressants, compared to their non-depressed peers.
The researchers found several notable driving behaviors linked to MDD. People with depression were more likely to engage in hard braking and sharp cornering, actions that suggest riskier driving habits. They also drove farther from home and visited a wider variety of destinations.
Over time, their driving patterns became less predictable, showing greater randomness in their routes and destinations.
These findings highlight how mental health can affect not just emotional well-being but also everyday activities like driving. Depression, especially in older adults, can influence decision-making, attention, and risk perception, all of which are critical for safe driving.
For those with MDD, the increased tendency to drive unpredictably or engage in abrupt maneuvers could put them at greater risk of accidents.
The study’s authors believe this research could lead to better support for older drivers with depression. For example, understanding these unique driving patterns might help professionals develop interventions like cognitive retraining or driver rehabilitation programs.
Occupational therapists could work with individuals to improve their driving safety while helping them maintain their independence and mobility.
This research emphasizes the importance of recognizing how depression affects behavior in everyday life. For older adults, maintaining the ability to drive safely is crucial for staying connected to their communities and accessing essential services.
By addressing the challenges faced by those with MDD, it may be possible to enhance their quality of life while reducing potential risks on the road.
