Efficacy Endpoints Primary: To determine if an intensive cognitive rehabilitation program changes, in a statistically significant way, the performance on a neuropsychological evaluation after 3 months of training, comparing to the control group (number of tests scored more than one standard deviation from the normal value). There will be analyzed the total and partial scores for each test. The individuals with cognitive deficits at baseline will be analyzes as rehabilitation group. The others (without cognitive deficits in cognitive evaluation at baseline) will be analyzed as a separated group of cognitive stimulation.
