Previous research has led to findings that support links between a positive mental outlook and physical health benefits such as lower blood pressure, less heart disease, and healthier blood sugar levels. In a recent study of mood changes in older adults, scientists also have discovered that healthy brain function may result in maintaining a positive outlook.
For this study, which was funded in part by NIA and published in the American Journal of Geriatric Psychiatry in September 2020, scientists proposed a potential neurobiological connection between an older adult’s mood with changes, over a period of time, in white brain matter and cognitive ability. White matter is where information is transmitted from one brain region to another. As we age, changes can occur in the white matter that may lead to thinking, walking, and balance problems.
