Researchers link aging with changes in brain networks related to cognition

Functional regions within the brain become less distinct and interconnected in the elderly over time, especially in those networks related to attention span and cognition. The finding, published by researchers at Duke-NUS Medical School in The Journal of Neuroscience, adds to current understanding of longitudinal decline in brain network integrity associated with aging.

"We currently live in a rapidly aging society," said the study's corresponding author, Associate Professor Juan Helen Zhou, a neuroscientist from the faculty of Duke-NUS' Neuroscience and Behavioural Disorders program. "Compared to cross-sectional studies, it is vital to understand brain changes over time that underlie both healthy and pathologic aging, in order to inform efforts to slow down cognitive aging."
