Preserving the Brain by Building the Muscle: Muscle Mass and Its Link to Dementia Prevention

Written By Brady Wirick

For many, the idea of maintaining cognitive function and reducing the risk of dementia revolves around brain games, mental exercises, and perhaps some dietary adjustments. Yet, research now suggests that building and maintaining muscle mass might play a pivotal role in preserving brain health. Let’s delve deep into the intricate relationship between muscle mass and dementia prevention.

Understanding Dementia

Dementia is a broad category of brain diseases that cause long-term and often gradual decreases in the ability to think and remember. This decline is severe enough to affect daily functioning, and Alzheimer’s disease is the most common form of dementia.

The Muscle-Brain Connection

The connection between muscle mass and brain health is a relatively recent area of research, but it’s rapidly gaining traction due to the compelling findings:

  1. Myokines: When you exercise, especially strength training, your muscles release chemicals called myokines. These molecules have numerous benefits, including anti-inflammatory effects and the ability to promote brain health. They aid in neuron growth and maintenance, potentially safeguarding against degenerative diseases.


  1. Insulin Sensitivity: Muscle mass helps in improving insulin sensitivity. Poor insulin sensitivity or insulin resistance is linked to brain inflammation and can increase the risk of cognitive decline and dementia. Thus, maintaining muscle might indirectly shield the brain by enhancing insulin function.


  1. Improved Blood Flow: Strength training and muscle-building activities stimulate better blood flow, ensuring that the brain receives adequate oxygen and nutrients vital for its optimal function.

Clinical Studies & Findings

Research increasingly supports the muscle mass-dementia connection:

– A study from the University of Eastern Finland found that individuals with higher muscle strength, as opposed to muscle mass, had a nearly 40% reduced risk of developing Alzheimer’s disease.  

– Another study published in the journal *Clinical Interventions in Aging* found that muscle strength, particularly in the lower body, was positively correlated with improved cognitive function in older adults.

While more extensive studies are required to cement these findings, the preliminary results suggest a promising link between muscle health and cognitive function.


Muscle Mass as a Marker of Overall Health

Maintaining muscle mass is not just good for the brain but is also an indicator of overall health. Good muscle tone is linked with:


– Reduced risk of falls and fractures

– Better metabolic health

– Improved cardiovascular function

– Enhanced immunity


A healthy body is more likely to house a healthy brain. As the body remains active and free from many age-related ailments, the chances of the brain remaining sharp and functioning also increase.


How to Build and Maintain Muscle Mass


  1. **Strength Training:** Incorporate weight lifting or resistance training into your exercise regimen. This doesn’t mean becoming a bodybuilder, but even light weights, when used consistently and progressively, can lead to significant muscle preservation and growth.


  1. **Adequate Protein Intake:** Ensure that you’re consuming enough protein, as it’s crucial for muscle repair and growth. Good sources include lean meats, dairy, eggs, legumes, and plant-based proteins like tofu and tempeh.


  1. **Stay Active:** Apart from targeted strength training, staying physically active in daily life also matters. Walking, gardening, climbing stairs, and even household chores can play a role in maintaining muscle tone.


  1. **Consistency:** Muscle maintenance requires consistent effort. A sporadic approach might not yield the desired results. Consistency in exercise and nutrition is key.


Beyond Muscles: A Holistic Approach

While building muscle mass might aid in reducing the risk of dementia, it’s essential to take a holistic approach:

– **Mental Stimulation:** Engage in activities that challenge the brain like reading, puzzles, learning new skills, or playing musical instruments.

– **Social Interaction:** Maintaining social connections and regular interactions can help in keeping the brain active and reducing the risk of cognitive decline.  

– **Healthy Diet:** Consume a balanced diet rich in antioxidants, Omega-3 fatty acids, and essential vitamins and minerals that support brain health and avoiding sodas, processed foods, and sugar.

-**Regular Chiropractic Care:** Your chiropractor can also insure adequate and healthy spinal movement to aid in nerve signals reaching your brain.


In Conclusion


The human body operates as an intricate web, with each component influencing the other. While the connection between muscle mass and dementia prevention might seem surprising initially, it’s a testament to the body’s interconnectedness. Building muscle does more than just improve physical appearance and strength—it’s an investment in long-term cognitive health.


As the saying goes, “A sound mind in a sound body.” By nurturing our bodies and building our muscles, we might be taking a significant step towards ensuring a future with a sharp and active mind. As research in this domain expands, it will only deepen our understanding of the profound ways in which physical health intersects with cognitive well-being.
