It has long been known that certain lifestyle choices are associated with a reduced likelihood of developing dementia. It includes eating right, exercising, quitting smoking and drinking alcohol.
For the new study, published in the journal JAMA Neurology, the team analyzed data from the ongoing Rush Memory and Aging Project. This project monitored the end-of-life lifestyle and mental function of 586 participants for 24 years. They all donated their brains for autopsy after death.
As expected, scientists found that those who lead a healthy lifestyle are more likely to maintain their mental health as they age. They found that each one-point increase in a person’s “lifestyle score” was associated with an increase in their “global cognitive score” at the end of life. Moreover, even if protein plaques and tangles or vascular network disorders appeared in the brains of these people, their mental abilities still remained high.
