<div>There was little to no effect of preoperative computer-based cognitive training or tablet-based preoperative cognitive exercise on the incidence of post-operative delirium for older adults surgical patients across three studies.</div>
<div> </div>
<div>Due to the overall lack of research, it is unclear if cognitive prehabilitation reduces the incidence of post-operative delirium. Additional limitations to this review include heterogeneity between studies and the potential for publication bias. Additional research is needed. </div>
<div>With cognitive prehabilitation, there was significantly reduced incidence of delayed neurocognitive recovery (three studies). Limitations to this review included the small number of included studies and heterogeneity among them. Other limitations included the potential for publication bias and lack of meta-analysis.</div>
<div>Cognitive prehabilitation reduced global cognitive impairment in two of three studies. Limitations to this review included the small number of included studies and heterogeneity among them. Other limitations included the potential for publication bias and lack of meta-analysis.</div>
