Living a healthy lifestyle could help you reduce your risk of dementia, even if you have a genetic risk of the disease, a study recently published in the peer-reviewed health journal JAMA found.
The study analyzed data from 196,383 adults of European ancestry aged 60 and older. Of that sample, the researchers identified 1,769 cases of dementia over a follow-up period of eight years.
Here’s what they found: Participants with high genetic risk and an unfavorable lifestyle were almost three times more likely to develop dementia versus those with a low genetic risk and favorable lifestyle. However, the risk of dementia was 32% lower in people with a high genetic risk if they had followed a healthy lifestyle, compared to those with an unhealthy lifestyle.
