Coupled changes in hippocampal structure and cognitive ability in later life

Introduction The hippocampus plays an important role in cognitive abilities which often decline with advancing age. Methods In a longitudinal study of community‐dwelling adults, we investigated whether there were coupled changes in hippocampal structure and verbal memory, working memory, and processing speed between the ages of 73 ( N = 655) and 76 years ( N = 469). Hippocampal structure was indexed by hippocampal volume, hippocampal volume as a...
