[Driving and Alzheimer's disease].

Area of Science:

• Gerontology
• Neurology
• Public Health

Context:

• Advanced age is associated with a higher risk of medical conditions affecting driving safety.
• Dementia, particularly Alzheimer's disease (AD), impairs critical driving functions like visuospatial skills, attention, memory, and judgment.
• The accident rate for drivers aged 80-85 is 9.4 per million kilometers, escalating dramatically to 163.6 for those with moderate AD.

Purpose:

• To highlight the increased traffic accident risk in elderly drivers with cognitive decline.
• To inform patients, families, and healthcare providers about driving cessation recommendations for individuals with dementia.
• To underscore the driving safety issues posed by individuals in the pre-dementia phase (mild cognitive impairment - MCI).

Summary:

• Individuals with mild dementia related to Alzheimer's disease (CDR stage 1) exhibit a substantially elevated rate of traffic accidents.
• Even individuals in the pre-dementia phase (CDR stage 0.5, MCI) present significant driving safety challenges.
• Legal mandates for investigating elderly driving performance exist in many regions, but not universally (e.g., France).

Impact:

• This research emphasizes the critical need for early detection and intervention regarding driving abilities in the aging population.
• It supports policy changes and clinical guidelines to enhance road safety by addressing cognitive impairment in drivers.
• Informing the public and policymakers about these risks can lead to more informed decisions about driving cessation and alternative transportation for vulnerable elderly individuals.
