Meta-analysis of 20 studies indicated that cognitive stimulation had a significant positive small-to-moderate effect on cognition (Hedges’s g = 0.313, 95% CI = [0.154-0.472]). Heterogeneity was low to moderate.
Meta-analysis of four studies indicated that cognitive stimulation had no significant effect on depressive symptoms (Hedges’s g = 0.557, 95% CI = [-0.213 to 1.326]).<br /><br />Meta-analysis of five studies indicated that cognitive stimulation had no significant effect on quality of life (mean difference = 0.551, 95% CI = [-0.889 to 1.992]).
Subgroup analyses revealed no significant difference for individual versus group therapy, for treatment at home versus outside of the home, or for ≤3 months versus >3 months of treatment.
