A new study suggests that older adults dealing with depression might be more prone to risky driving behaviors. Published in JAMA Network Open, the study highlights a connection between major depressive disorder (MDD) and driving habits like hard braking and speeding among those aged 65 and older. This relationship was evident even when accounting for medications that could impair driving.
The researchers concentrated on this age group because depression in later life is common but often overlooked, leading to significant impacts. According to Ganesh M. Babulal, PhD, OTD, from Washington University School of Medicine in St. Louis, depression is linked to cognitive challenges like slower reaction times and difficulties with executive functions and attention, all crucial for safe driving. As the number of older adults grows and many continue to drive for independence and social connection, understanding how depression affects driving is vital for safety and quality of life.
This study builds on earlier research showing how mental health issues can influence driving among older adults. However, prior studies often relied on controlled settings or self-reports, which might not fully capture real-world experiences. To address this gap, Babulal and his team analyzed real-world data from 395 participants aged 65 and up, 85 of whom had MDD. From mid-2021 to the end of 2023, they used vehicle data to track behaviors like hard braking, cornering, route randomness, speeding, and distance traveled. Those with depression exhibited more frequent risky driving behaviors compared to their non-depressed peers, even after considering various demographic and health factors.
The findings highlight the need for interventions tailored to older drivers with MDD to improve road safety and maintain independence. However, the study only assessed initial depression levels and did not track changes over time or co-occurring psychiatric conditions. Despite focusing on older adults, the results could be relevant for younger individuals with depression as well.
Depression affects driving safety at any age, potentially leading to distractions, slower reactions, and impulsive behaviors. Younger drivers may have better reflexes, but symptoms like fatigue or brain fog can still impair driving. This study emphasizes that depression affects daily functioning, including driving. Risks and habits might vary by age due to differences in lifestyle and coping strategies. Further research is needed to understand these effects in younger people and develop appropriate interventions.
For drivers with depression, regular medical follow-ups can help maintain safety and well-being. Regular mental health screenings are also recommended for older adults without a depression history to identify risky behaviors early. Interventions could include therapy to enhance self-awareness and understand driving limitations. All drivers should self-assess before driving, paying attention to feelings of fatigue or distress, and avoid driving if something feels off. Simple precautions like taking breaks, minimizing distractions, and sticking to familiar routes can enhance safety. Mental and physical sharpness is key to safe driving, making mental health care essential for confidence and safety on the road.
