[Mild dementia and driving ability. Part 2: Assessment and its consequences in practice]

Area of Science:

• Traffic and transport psychology
• Medical statistics

Background:

• Safe driving relies on complex sensory and mental processes.
• Diseases and physiological changes can impair driving performance.
• Dementia significantly impacts driving ability over time.

Purpose of the Study:

• To discuss the assessment of driving fitness in patients with dementia.
• To highlight the importance of a comprehensive evaluation beyond cognitive function.
• To guide physicians on counseling patients regarding driving cessation.

Main Methods:

• Review of legal frameworks and essentials in traffic psychology and statistics.
• Discussion of various assessment approaches and tools for driving ability.
• Emphasis on considering overall functioning and risk factors.

Main Results:

• Moderate to severe dementia renders individuals unfit to drive.
• Driving ability may be preserved in mild dementia for a period.
• No single test can definitively determine fitness to drive in mild dementia.

Conclusions:

• Driving ability is inevitably lost during the course of dementia.
• Prompt discussion of driving fitness is crucial upon dementia diagnosis.
• Physicians should counsel and support patients and families through driving cessation.
