NCT03263247

Brief Summary

The current project aims to investigate the trajectories of the visual imaging cognitive training (CT) and alphabet search training using fMRI in patients with amnestic mild cognitive impairment (MCI) and healthy elderly controls (HE). MCI patients will be grouped according to biomarkers (PET PIB).
