Cognitive Training in Patients With MCI Using fMRI

We will include 40 subjects with amnestic mild cognitive impairment (MCI) multiple domain clinical diagnostic, over 60 years old, recruited through the outpatient clinic of University of Sao Paulo General Hospital. We will also include 20 healthy subjects, over 60 years old, recruited in the community. All the participants will be evaluated by neurologists specialized in cognitive neurology and subjected to a neuropsychological assessment. The 40 participants with MCI and 20 healthy subjects will receive 6 sessions of visual imaging training. After this first study, they will receive cognitive training with alphabet search training. This will be a longitudinal study. MCI patients will be grouped according to biomarkers (PET PIB).
