Scoping review identifies gaps in understanding physical activity impacts on cancer and dementia, suggesting further exploration is needed.
Background: Comorbid cancer and dementia, which share common risk factors and significantly burden the healthcare system, affect a growing number of individuals, especially the aging population. As both conditions place a substantial burden on healthcare systems and may be underdiagnosed, there is an urgent need to explore effective management strategies, including the potential benefits of physical activity, which has shown promise in mitigating cognitive decline and improving physical function in both cancer and dementia populations.This scoping review aimed to explore the current knowledge of physical activity for individuals with comorbid cancer and dementia, identifying gaps in understanding and highlighting the need for future research in this area. Summary: This scoping review followed the 5-stage framework outlined by Arksey and O'Malley, with a focus on identifying the effects of physical activity on individuals with comorbid cancer and dementia. The review involved a comprehensive search across multiple databases, selecting relevant studies based on predefined criteria, and summarising key findings to highlight research gaps and inform future studies. Out of 263 records identified from multiple databases, none were retained for full-text screening due to exclusions based on review articles, non-human participants, lack of comorbid cancer-dementia, and absence of a physical activity/exercise component.
