Emily Willroth, an assistant professor of psychological and brain sciences in Arts & Sciences at Washington University in St. Louis is researching wellness and the human brain as people age. Her lab is playing a role in recent discoveries that show how a sense of happiness may have a protective effect against dementia.

"Recent research suggests that people with higher levels of wellbeing maintain memory and thinking abilities for longer, into older adulthood. And they are less likely to develop Alzheimer's disease and related dementias," said Willroth.

It’s not so simple as to tell people to “be happy”; instead, certain behaviors and habits are associated with a sense of happiness, such as exercise, being active in social circles and having a sense of purpose.

"Recent research from our lab suggests that changes in wellbeing are associated with later changes in memory and thinking abilities."
