Vigorous Physical Activity May Lower Dementia Mortality Rates, Study Finds.
A recent study published in Lancet Healthy Longevity suggests that engaging in vigorous physical activity may contribute to lowering dementia mortality rates compared to moderate physical activity (Source: Medical News Today). With over 55 million people worldwide affected by dementia, the study explores the potential impact of different activity levels on dementia-related mortality.
Dementia encompasses a range of neurological conditions affecting the brain, with Alzheimer’s disease being the most common type. As of 2019, approximately 1.62 million deaths globally were attributed to dementia. Making it the fourth leading cause of death among individuals aged 70 or older.
While there is currently no cure for most types of dementia, managing symptoms and increasing life expectancy are achievable through medications and certain lifestyle changes. The study led by Dr. Borja del Pozo Cruz, a principal researcher in applied health sciences, delves into the relationship between physical activity levels and dementia-related mortality.
The researchers sought to differentiate between moderate and vigorous physical activity, considering the prevalence of dementia and the often-recommended role of physical activity in preventing Alzheimer’s disease. Dr. Cruz highlighted the generic nature of guidelines, lacking specific directives on optimizing the benefits of physical activity.
The researchers linked participants to the National Death Index until December 31, 2019, identifying 2,176 participants who died due to Alzheimer’s disease as the leading cause. The findings suggested a significant association between engaging in vigorous physical activity and a lower risk of Alzheimer’s disease-related mortality.
While the study contributes valuable insights, it is crucial to note that further research, including clinical trials and broader population studies, is needed to establish a more comprehensive understanding of the relationship between physical activity levels and dementia outcomes. As the global population ages, exploring preventive measures such as physical activity becomes increasingly vital in addressing the challenges posed by dementia.
