Cognitive speed of processing training delays driving cessation.

Area of Science:

• Gerontology
• Cognitive Neuroscience
• Transportation Safety

Background:

• Aging population necessitates strategies to extend safe driving abilities in older adults.
• Maintaining driving independence is crucial for the quality of life and autonomy of seniors.
• Driving cessation significantly impacts social engagement and access to essential services for older individuals.

Purpose of the Study:

• To investigate the effectiveness of cognitive training in delaying driving cessation among older adults.
• To determine if speed of processing training influences the risk of driving cessation.
• To analyze the impact of cognitive interventions on driving longevity in the elderly.

Main Methods:

• Combined data from two studies to assess cognitive training's effect on driving cessation.
• Utilized stratified Cox hazard regressions to analyze cessation risk.
• Examined risk factors including training participation, baseline driving status, and visual acuity.

Main Results:

• Older drivers with cognitive speed of processing deficits who underwent training showed a 40% lower likelihood of driving cessation over 3 years.
• The hazard ratio for driving cessation was 0.596 (95% CI 0.356-0.995, p = .048) for trained participants.
• Only 9% of participants completing eight or more training sessions ceased driving, compared to 14% in the untrained group.

Conclusions:

• Speed of processing training demonstrates potential in delaying driving cessation for older adults experiencing processing difficulties.
• Cognitive interventions targeting specific deficits may be a viable strategy to support continued driving.
• This finding supports the development of targeted programs to enhance driving safety and independence in aging populations.
