0.748 on the testing CN cohort and MCI cohort respectively, significantly better than those built upon regional GMvolumemeasures, demographic and cognitive measures, and their combination (Table 2). The deep learning prediction model also identified informative brain regions, mainly located in the lateral temporal, temporoparietal, and prefrontal cortices (Fig. 2). The predicted risk of cognitive decline obtained by the deep learning model also clustered the CN and MCI subjects into subgroups with significant differences in their rapidity of cognitive decline (Fig. 3). Conclusions: The deep learning prediction model could achieve promising performance for early predicting rapidity of cognitive decline of individual older adults based on their baseline MRI images and demographic and cognitive measures.
