A new study has found that stressful life experiences can age the brain approximately 1.5 years, and that, specifically, experiencing one of these 27 stressful life events could lead to Alzheimer’s and related forms of dementia later in life.
Learn more about the effects of stress on brain health and the 27 life events that can cause damage and lead to Alzheimer’s.
The latest study to evaluate the effects of stress on brain health was presented at the Alzheimer’s Association International Conference in London. Researchers from the University of Wisconsin School of Medicine and Public Health evaluated data from 1,320 participants who shared information about their own stressful life experiences and then participated in cognitive tests.
Researchers found that every stressful event was equal to 1.5 years of brain aging across all participants, except for African-Americans, where every stressful event was equal to 4 years of brain aging.
The study also found that African-Americans reported 60% more stressful events on average than Caucasians, which may help to explain why there is a higher incidence of Alzheimer’s there.
The Alzheimer’s Association’s Dr. Maria Carrillo, said:
“The stressful events were throughout the lifespan – a variety of things that you can imagine would be impactful and stressful. Dementia and brain health should be thought of as life-course issues, not just mid-life or late-life [problems]. We have to start thinking about brain health from birth, if not before.”
The link between Alzheimer’s and stress needs to be further examined, but researchers believes that stress can cause inflammation in the brain, making the brain more susceptible to health problems like dementia. Stress can also lead to depression, a known risk factor for Alzheimer’s and related forms of the disease.
These stressful life events have been linked to causing damage to the brain, which could lead to Alzheimer’s.
The likelihood of developing the disease could increase after experiencing just one of the events listed below:
