How Exercise and Physical Activity Linked to Reduced Mortality Risk in Individuals with Dementia

Research has consistently shown that exercise is linked to numerous health benefits; this is also true for individuals with dementia. A recent study published in the British Journal of Sports Medicine found that maintaining or starting physical activity after a dementia diagnosis can significantly lower the risk of mortality.

The study, which included over 60,000 participants with dementia, revealed that maintaining physical activity before and after diagnosis was associated with the lowest mortality risk. Notably, starting physical activity after diagnosis reduced mortality risk by 20% or more. All levels of sustained physical activity were linked to decreased mortality risk.

How This Impacts The Management of Dementia

These findings suggest that exercise should be greatly encouraged among people with dementia. According to Eric D. Vidoni, PT, PhD, an associate professor of neurology, maintaining physical activity supports health, even after a dementia diagnosis. Vidoni also highlighted that light activity held almost as much benefit as moderate and vigorous activity.

The study’s results have significant implications for dementia management. Dementia is a leading cause of death, and the number of people with dementia is increasing. Physical activity can offer multiple benefits, from weight management to decreasing the risk of heart disease, and may also help lower the risk of developing dementia. Incorporating physical activity into daily routines can be achieved through various strategies.

Individuals with dementia can work with doctors, physical therapists, and caregivers to develop personalized exercise plans. An expert suggests that care strategies should encourage various forms of physical activity tailored to individual capabilities and preferences.

Experts recommend that individuals with dementia engage in regular physical activity, such as vigorous physical activity for 20 minutes or more at least three times weekly or moderate physical activity for 30 minutes or more at least five times weekly. Even light physical activity, such as walking or stretching, can be beneficial.

While the study has limitations, including a focus on Korean individuals and reliance on self-reported physical activity levels, its findings highlight the potential benefits of exercise for individuals with dementia. It is worth noting that physical activity can be adapted to individual needs and abilities.

By incorporating exercise into daily routines, individuals with dementia may reduce their mortality risk and improve overall health outcomes. Implementing exercise plans for these individuals requires a collaborative approach.

Healthcare professionals, caregivers, and family members can play a crucial role in supporting and encouraging physical activity in individuals with dementia. They can help develop personalized exercise strategies, while caregivers can provide support and encouragement. Community-based programs, online resources, and sessions with trained therapists can also facilitate physical activity.

By promoting physical activity, we can improve the lives of individuals with dementia and potentially extend life expectancy. As Glatt notes, exercise can be safe, engaging, and accessible for individuals with dementia at any fitness level. By prioritizing physical activity, we can enhance dementia management and improve overall health outcomes.
