<div>The findings suggest that cognitive training has modest effects on improving the cognitive skills of individuals with mild to moderate Parkinson's disease (g = 0.23). Cognitive training had significant effects on working memory (g = 0.74), processing speed (g = 0.31) and executive function skills (g = 0.30). Limitations to this review include a limited number of included studies and heterogeneity between studies.</div>
