Older adults with major depressive disorder (MDD) may be at a higher risk of engaging in unsafe driving behaviors, according to a recent study published in JAMA Network Open. The research sheds light on the cognitive and emotional challenges associated with depression and how these may impact driving safety in older populations.

The Study The researchers used data from a cohort of adults aged 65 and older diagnosed with MDD. Participants’ driving behaviors were monitored through telematics devices installed in their vehicles. The study revealed a significant correlation between depressive symptoms and risky driving patterns, such as:

• Hard braking.
• Speeding.
• Failing to maintain safe following distances.

These behaviors suggest that depression could impair cognitive functions critical for safe driving, including attention, decision-making, and reaction time.

Cognitive Impairments in Depression Depression often involves symptoms such as decreased concentration, slower cognitive processing, and fatigue—all of which can affect driving ability. Older adults may also face age-related cognitive decline, compounding the impact of depressive symptoms on driving performance.

Implications for Public Health This study highlights the need for targeted interventions to support older adults with depression, including:

• Routine mental health screenings for older drivers.
• Cognitive training programs to enhance driving safety.
• Encouraging alternative transportation options when needed.

Addressing the Issue Experts recommend that families and healthcare providers remain vigilant about the driving abilities of older adults with depression. Open discussions about mental health and driving safety can help reduce risks and promote overall well-being.
