Boosting Brain Health: How Exercise and Nutrition Are Changing Dementia Care
A new study from Karolinska Institutet reveals a promising link between simple lifestyle interventions – daily physical exercise and protein-rich nutrition – and improved quality of life for individuals living with dementia. Published in Alzheimer’s & Dementia, the research demonstrates that this combination can lead to increased independence in everyday tasks.
The Challenge of Frailty in Dementia Care
Older adults in residential care settings are particularly vulnerable to malnutrition, muscle weakness and frailty. These factors significantly impact both their health and overall well-being. Previous research, known as the OPEN study, already indicated that a program focused on exercise and nutrition could improve physical function, muscle mass, and nutritional status. This latest analysis delves deeper, exploring the connection between the program and a reduction in the need for caregiver support.
Study Details: A Focus on Real-World Impact
The study involved 102 residents from eight nursing homes in the Stockholm area. For twelve weeks, one group participated in a program that included regular standing exercises and the consumption of one to two nutritional drinks enriched with protein. Researchers carefully monitored the level of assistance participants required with essential daily activities like personal hygiene, dressing, and mobility.
Interestingly, when the data was initially analyzed across all residents, no significant differences were observed. However, a more nuanced picture emerged when the results were categorized by ward type. In dementia-specific units, those who participated in the exercise and nutrition program showed noticeable improvements in their functional abilities, requiring less caregiver time compared to the control group.
“One possible explanation is that people in dementia units had better physical conditions for improving their functional ability and were therefore able to do more things themselves after the intervention.”

The Rise of Personalized Dementia Care
This research underscores a growing trend towards personalized care in dementia management. Recognizing that individuals respond differently to interventions, healthcare providers are increasingly focusing on tailored approaches. The Karolinska Institutet study highlights the potential of non-pharmacological interventions – those that don’t rely on medication – to significantly improve outcomes.
The findings also suggest that improvements in physical function can directly translate to a reduced need for assistance, potentially easing the burden on caregivers and improving the overall efficiency of care facilities. However, researchers caution that these analyses are secondary and further investigation is needed.
Future Directions: Measuring Care Time as a Primary Outcome
“More studies are needed where care time is a primary outcome and where organizational factors, such as staffing levels and work routines, are closely monitored,” emphasizes Anders Wimo. This points to a need for research that not only assesses the impact of interventions on individuals but also considers the broader systemic implications within care settings.
Karolinska Institutet’s Center for Alzheimer Research is at the forefront of this work, aiming to understand the mechanisms behind Alzheimer’s disease and other dementias to develop effective prevention, diagnostic, and treatment strategies.
FAQ: Exercise, Nutrition, and Dementia
- What type of exercise was used in the study? Participants engaged in standing exercises several times a day.
- How much protein was added to the diet? Participants consumed one to two nutritional drinks with extra protein daily.
- Were there any conflicts of interest? Danone Nutricia Research provided the nutritional drinks but did not participate in data collection or analysis.
- Is this a cure for dementia? No, this study demonstrates improvements in function and independence, but it is not a cure.
Pro Tip: Even small increases in physical activity, like short walks or chair exercises, can make a difference in maintaining independence and quality of life for individuals with dementia.
