The Impact of Regular Physical Activity on the Mental Health and Well-Being of Dementia Patients in High-Income Countries-A Systematic Scoping Review

Background: Dementia is a term used to describe a group of symptoms impacting memory, thinking, and social abilities. Evidence suggests a positive role of physical activity in physical and mental well-being in general. This systematic scoping review aimed to gather, summarise, and analyse evidence of the impact of physical activity on the mental health and well-being of dementia patients. Methods: A comprehensive systematic search of mainly primary research was conducted using several databases. Peer-reviewed studies in high-income countries published between 2005 and 2023 were included. The systematic scoping review was performed using the framework outlined by the Joanna Briggs Institute (JBI) and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) statement. Results: Twenty-four articles (including 93,984 participants) were included in the analysis. Most articles (21) reported that physical activity (particularly regular physical activity) is associated with decreased depression score, decreased cognition impairment, and fewer falls, all of which contributed to improved well-being among dementia patients. These studies showed that there is a significant positive relationship between the level of physical activity and the level of improvement in the mental health and well-being of dementia patients. Conclusions: Findings from this systematic scoping review provide relatively reliable evidence that regular physical activity may improve the mental health and well-being of dementia patients. Systematic reviews and meta-analyses may be required to further confirm these findings.
