### Cognitive Results  
Cognitive data were gathered from a total of 23 subjects including 13 participants from Group A and 10 participants from Group B (Table 3). In the global cognitive score, there was no significant effect of time (in Group A, pre: M = 91.5, SD = 9.6; post: M = 93.4, SD = 7.0 and in Group B, pre: M = 99.2, SD = 8.8; post: M = 99.5, SD = 7.6, F(1,21) = 0.51, \(p\) = 0.48), and we did not find any interaction effect (F(1,21) = 0.30, \(p\) = 0.59). In memory, there was a significant effect of time with improvement in memory for both groups (in Group A, pre: M = 91.8, SD = 13.5; post: M = 99.7, SD = 9.1; and in Group B, pre: M = 97.6, SD = 9.7; post: M = 99.9, SD = 9.2, F(1,21) = 4.29, \(p\) = 0.05) with a much larger improvement in Group A than in Group B but without a significant interaction effect (_p_ = 0.26). The significant effect of time was also found in verbal memory (F(1,21) = 9.29, \(p\) = 0.01), in delayed verbal memory (F(1,21) = 4.40, \(p\) < 0.05) without interaction effect in verbal memory (F(1,21) = 0.19, \(p\) = 0.67) and in delayed verbal memory (F(1,21) = 0.21, \(p\) = 0.66). In non-verbal memory, we did not find any effect of time (F(1,21) = 0.03, \(p\) = 0.88) and no interaction effect (F(1,21) = 1.44, \(p\) = 0.25). In delayed non-verbal memory, we found an interaction effect (F(1,21) = 5.75, \(p\) < 0.05) with a significant improvement in Group A between pre- and post-intervention (pre: M = 89.8, \begin{table}

Table 3: Results for the NeuroTrax cognitive domains and memory sub-components pre-intervention and post-intervention according to groups. SD = 11.7, post: M = 97.2, SD = 13.8, \(p\) < 0.05) whereas no significant difference was found in Group B, apart from a decrease in the delayed non-verbal memory score (pre: M = 105.1, SD = 10.4, post: M = 96.1, SD = 12.6, \(p\) = 0.12). In executive function, there was no main effect of time (in Group A, pre: M = 92.0, SD = 11. 4, post: M = 92.2, SD = 8.1; and in Group B, pre: M = 100.6, SD = 11.1, post: M = 101.1, SD = 10.4, F(1,21) = 0.03, \(p\) = 0.86) and no interaction effect (F(1,21) = 0.01, \(p\) = 0.93).
