Relationship stressors linked to dementia

A prospective longitudinal study of 800 women followed for nearly 40 years showed the number of psychological stressors women had at the start of the study in 1968 increased their risk of dementia by 15% and Alzheimer’s disease (AD) by 20%.

Long-standing distress, measured throughout the study, and the number of psychological stressors, were independently associated with the development of AD, the researchers found.

The link between the number of psychological stressors and incidence of AD was similar in those with early and late onset AD (before or after age 75).
