In the latest instalment of a series on dementia, experts are emphasizing the importance of staying physically and mentally active to maintain cognitive health. David Merrill, a psychiatrist and director of the Pacific Brain Health Centre, explains that the “use it or lose it” principle applies to the brain just as it does to muscles and bones. Research from Monash University in Australia has revealed a correlation between greater thigh muscle volume in midlife and larger brain volumes, suggesting that physical fitness may play a role in brain health. While the connection between physical and cognitive health is not fully understood, the findings underscore the importance of staying active to support overall well-being. These insights provide hope for individuals affected by dementia and their caregivers, offering potential strategies for maintaining brain health and potentially delaying the onset of cognitive decline. As research continues to uncover the complex relationship between the body and the brain, the key takeaway remains clear: staying active, both physically and mentally, is crucial for preserving cognitive function and overall quality of life.
