Frontal function and executive processing in older adults: Process and region specific age-related longitudinal functional changes

► There are mixed findings on age-related increase in frontal activity and cognition. ► We examine longitudinal changes in frontal rCBF and different executive abilities. ► Baseline frontal rCBF had mixed correlations with different abilities and regions. ► Sustained or improving performance correlated with decreasing frontal rCBF. ► Aging frontal activity changes is process and region specific and not generalized.
