Taxi, Ambulance Drivers Show 1% Alzheimer's Death Rate in 9 Million U.S. Records

Summary
A 2024 analysis of nearly 9 million U.S. death certificates found taxi and ambulance drivers had the lowest Alzheimer's death risk among 443 occupations, with about 1 in 100 deaths tied to the disease versus roughly 1 in 60 overall.
The apparent advantage was linked not to driving itself but to constant real-time navigation—tracking location, destination and route changes—because fixed-route jobs such as bus driving and piloting did not show the same pattern.
London taxi research offers a possible mechanism: drivers who master more than 25,000 streets showed greater posterior hippocampus gray matter, and that brain region is among the first damaged by Alzheimer's.
The report says the finding could extend beyond drivers to map-intensive work such as GIS, cartography and urban planning, though whether screen-based spatial reasoning protects the brain as real-world navigation does remains untested.
