Abstract
PURPOSE OF REVIEW: To summarize and evaluate evidence available on the effects of yoga on cancer-associated cognitive decline (CACD). RECENT FINDINGS: A systematic review was conducted using four databases of articles published before January 1, 2020. Ten articles met the inclusion criteria (six randomized controlled trials, two single-arm studies, one non-randomized controlled trial, and one case series study). Studies were predominantly conducted with breast cancer patients using low-intensity hatha yoga programs. Of the 10 articles, five reported some positive effects on CACD, but significant biases were possible due to design shortcomings. Cohen's d effect sizes ranged from |0.03| to |0.74|. The evidence to date is insufficient to suggest that yoga is beneficial for attenuating CACD. More rigorous trials controlling for non-specific factors are warranted. The field would also benefit from examining self-delivered modes of yoga for treating CACD in various cancer populations to enhance practice sustainability and generalizability.
