Healthy Lifestyle May Offset Cognitive Decline Even in People With Dementia

As we age, our cognitive abilities may gradually decline. However, recent research suggests that adopting a healthy lifestyle can significantly impact cognitive health, even in individuals with signs of dementia. In this article, we explore the relationship between lifestyle choices and cognitive decline, emphasizing the importance of maintaining good habits for brain health.


The Study


A study published in JAMA Neurology on February 5, 2024, sheds light on the potential benefits of healthy living for cognitive function1. Researchers examined data from the Rush Memory and Aging Project, a longitudinal study spanning from 1997 to 2022. The study included 586 participants who had since passed away and undergone autopsies.


Lifestyle Factors and Cognitive Function


Participants were evaluated based on their lifestyle choices, including:


Physical Activity: Regular exercise was associated with better cognitive function.

Diet: A healthy diet positively impacted cognitive health.


Smoking and Alcohol: Avoiding smoking and limiting alcohol consumption contributed to cognitive well-being.


Cognitive Activities: Engaging in mentally stimulating activities also played a role.

Each participant received a lifestyle score ranging from 0 to 5, reflecting their adherence to these factors. Remarkably, a healthier lifestyle was linked to improved cognitive function, regardless of whether participants had brain pathologies like Alzheimer’s disease. Higher lifestyle scores were also associated with reduced levels of beta-amyloid plaque, a protein commonly found in Alzheimer’s patients’ brains.


Why Does Lifestyle Matter?


While more research is needed to fully understand the mechanisms, scientists propose several reasons why lifestyle choices impact cognitive health:


Brain Cell Growth and Plasticity: Healthy behaviors may promote the growth of new brain cells and enhance plasticity.


some lifestyle may combat brain inflammation, which contributes to cognitive decline.

Vascular Function: Good habits support healthy blood flow to the brain.


Even Dementia Patients Benefit


Surprisingly, even individuals diagnosed with dementia experienced less cognitive decline when they adopted healthier habits. This finding challenges the notion that cognitive decline is irreversible once dementia sets in. Instead, adhering to and improving upon multiple lifestyle factors may slow cognitive decline and enhance behavioral outcomes, such as mood and specific aspects of cognition




In summary, a healthy lifestyle can be a powerful tool for maintaining cognitive function as we age. Whether you’re actively experiencing cognitive decline or simply want to protect your brain health, consider incorporating physical activity, a balanced diet, and other positive habits into your daily routine. By doing so, you may offset cognitive decline and enjoy a sharper mind well into your golden years.
