Researchers have discovered that smaller muscles, particularly in the temporalis region, may be an indicator of a higher risk of dementia. According to Ryan Glatt, senior brain health coach and director of the FitBrain Program at Pacific Neuroscience Institute, people with smaller temporalis muscles are 60% more likely to develop Alzheimer’s disease or dementia.
The study analyzed data from over 600 cognitively healthy individuals who participated in the Alzheimer’s Disease Neuroimaging Initiative. Participants were grouped into categories based on muscle size and tracked for about five years for any signs of dementia, brain structure changes, or cognitive decline.
Glatt explains that a smaller temporalis muscle can indicate sarcopenia, which is age-related muscle loss and weakness. This condition is linked to frailty, reduced mobility, and metabolic dysfunction, all factors associated with cognitive decline.
While the exact reason behind this link remains unclear, Glatt suggests that muscle loss plays a role in the larger processes affecting brain health. He recommends addressing muscle loss through resistance training, proper nutrition, and regular physical activity as essential for maintaining overall health and may offer protective benefits for cognitive function.
Other warning signs of dementia include poor physical health, history of stroke, lack of exercise, diabetes, and certain genetic factors. Researchers agree that prevention is key, with methods including taking care of heart health, being social, trying to learn something new daily, and addressing vitamin deficiencies.
By understanding the link between muscle size and dementia risk, individuals can take steps to maintain their overall health and reduce their likelihood of developing this devastating condition.
