52 Patients with NCD performed significantly worse on the MoCA than patients without NCD, both at baseline and at follow–up. The same was true for the MoCA–DS executive functioning. At baseline, the difference in performance on the MoCA–DS memory was also significant, while performance on the MoCA–DS language and abstract reasoning differed significantly between both patient groups at follow–up. Performance on the other MoCA– DS did not differ significantly between both patient groups (Table 3.4). Table 3.4. Mean ( SD ) and t –test results for Montreal Cognitive Assessment (MoCA) domain (MoCA–DS) and total scores (MoCA–TS) at baseline and follow–up, for patients with and without neurocognitive disorders (NCD) and for the total sample.
