Beneficial Effect of Multidomain Cognitive Training on the Neuropsychological Performance of Patients with Early-Stage Alzheimer’s Disease

Table 4

The effect of the intervention (estimated by comparing the mean difference of the two neuropsychological assessments (baseline minus endpoint in each group) between the two groups (training group versus controls)) in the training group compared to the control group.
