A new study raises the possibility that jobs that require frequent spatial processing—such as figuring out a taxi route or the best way to navigate to a hospital—could lead to lower rates of death from Alzheimer’s disease. Researchers from Mass General Brigham investigated this possibility by using national data on the occupations of people who had died to evaluate risk of death from Alzheimer’s disease across 443 professions. They found that taxi driving and ambulance driving were associated with a lower rate of death from Alzheimer’s disease compared to other professions. Results are published in BMJ.
