Abstract
While the CAIDE score is an established mid-life risk assessment tool for the longitudinal prediction of dementia, its application as a measure of elevated cognitive risk in late adulthood is unclear. One hundred one healthy individuals (aged > 55) were tested using detailed neuropsychological assessments, as well as structural and functional MRI. Participants were divided into a low-risk group (CAIDE < 7) and a high-risk group (CAIDE > 6). High-risk participants had significantly worse cognitive performance in the Trail-Making Test results (TMT-B: t = -4.03, p = 0.0001), and significantly smaller global brain volumes (e.g., brain segmentation volume: t = 2.898, p = 0.0485) and regional volumes (e.g., accumbens volumes: tleft = 3.928, p = 0.036, Cohen's d = 0.828; tright = 3.151, p= 0.0485, Cohen's d = 0.656). High-risk participants also showed a trend for reduced functional connectivity in the default mode, salience, and central attention networks. Overall, the CAIDE score might help identify cognitively high-risk individuals in a late adulthood population.
