A new study finds those with Alzheimer's are more likely to have had less mentally demanding careers than people the same age who did not develop the brain disease.
Researchers at the Case Western Reserve University School of Medicine examined 122 people with Alzheimer's and 235 people free of the disease, all over age 60. They interviewed those who were disease-free about their job history from their 20s through their 50s, and got the same information from family members of those with the affliction.
Scientists collected information on the type of job and industry, the length of time on the job and the subjects' most important activities. Mental, physical, social and fine motor skills required of the job were scored using scales developed by the U.S. Department of Labor.
In the journal Neurology, researchers reported today that, over several decades, people with Alzheimer's had held jobs with lower mental demands than those in the control group.
