Last Aging Class Lecture (Guest Speaker) Dr Alexander Crizzle
• Canada population growing rapidly because of age.
• Crash rates are lowering by time for 80+ people
• Youngest population has a very high crash rate = irresponsible
• Age 6069 safest of them all.
• Seniors 4x more likely to be seriously injured & hospitalized more than
drivers 1624 years.
• Treatment of injuries is more costly, recovery slower, less complete
• Most (3 of 4) crashes involving older drivers are multiple vehicle
• Will be 5th top death in 2030 (car accidents)
Why the increased accident rate?
• Acuity & field of view, night vision, sensitivity to glare, contrast
Perceptual & Psychomotor
• ability to judge distance & speed of moving vehicles
• slower reaction times
• more time to perceive, and organize
• decreased flexibility & rangeofmotion (neck, shoulders)
Cognitive deficits = people with dementia 2028 will double from
Diagnosis of dementia does not automatically mean no driving (some
people with mild dementia can drive albeit for a limited period of time
before they must give up the keys).
Older drivers tend to drive less often, less likely to be caught for
speeding. More likely for improper lane changes, reversing, failure to
obey signs & signals. Impacts of cessation
• social isolation
• early mortality
• increased depressive symptoms
• increased reliance on family/friends
