Study suggests taxi and ambulance drivers have lower Alzheimer's risk due to navigation
Key points
- Taxi and ambulance drivers have a lower Alzheimer's mortality risk.
- The study analyzed 9 million death certificates from 2020-2022.
- Continuous real-time navigation is linked to the reduced risk.
- The hippocampus, involved in spatial navigation, may be key.
Reduced Alzheimer's Risk in Specific Occupations
A 2024 study examining nearly 9 million U.S. death certificates from January 2020 to December 2022 revealed that taxi and ambulance drivers had the lowest risk of dying from Alzheimer's disease among 443 occupations. After adjusting for various demographic factors, approximately 1 in 100 taxi and ambulance drivers died of Alzheimer's, compared to 1 in 60 people overall.
The Role of Continuous Navigation
Researchers concluded that the reduced risk was not due to driving itself, but specifically to continuous real-time navigation. This involves constantly locating oneself in space, tracking a destination, and updating a mental map as conditions change. Occupations with fixed or predetermined routes, such as bus drivers and aircraft pilots, did not show a similar advantage.
Hippocampus Engagement and Alzheimer's
The association between navigation-heavy work and lower Alzheimer's risk is believed to center on the hippocampus. This part of the brain is responsible for memory and spatial navigation, and it is one of the first regions damaged by Alzheimer's disease. Problems with spatial navigation and orientation are often early indicators of the disease, sometimes appearing before memory loss.

Reporting from
A 2024 study of nearly 9 million U.S. death certificates found that taxi and ambulance drivers have a significantly lower risk of dying from Alzheimer's disease compared to other occupations. This suggests that continuous real-time navigation, rather than driving itself, may contribute to this reduced risk by engaging the hippocampus, a brain region crucial for memory and spatial navigation.
