Weight Training Could Reduce Risk Of Dementia In Older Adults

(Credit-Canva)

Used as an umbrella term, <span><a href="https://www.healthandme.com/health/dementia">dementia</a></span> is a condition that affects your memory, thinking as well as one's daily activities. While it is concerning to forget things every now and then, dementia essentially chips away at a person’s identity, changing the way they think and behave. Affecting nearly 57 million people worldwide (World Health Organization) in 2021, dementia can occur due to diseases and any sort of injury to the brain. It is the 7th leading cause of death globally and 60-70% of these cases are Alzheimer's disease. 

According to the Cleveland Clinic, dementia is caused by damage to your brain, it affects your brain’s nerve cells which blocks the brain’s ability to communicate properly with other parts of your body. They also explained that while dementia cannot be prevented, lifestyle choices can reduce or increase its risk. 

Simple and accessible methods, like incorporating exercise into our lives, are seen as very important for helping people maintain a good quality of life as they get older and for reducing the impact of this condition on individuals and their families. While we already know that regular exercise can help keep our brains healthy and lower the chances of getting dementia, new research is pointing towards a specific type of exercise: weight training. 

According to a new study published in the GeroScience journal, doing exercises to build muscle might also help protect the brains of older individuals from developing dementia.

To understand this potential link better, researchers conducted a study with older adults who had already been diagnosed with mild cognitive impairment, which are early signs of potential future dementia. They divided these participants into two groups. One group participated in a weight training program that gradually increased in difficulty and intensity, happening twice a week. The other group, acting as a comparison, did not engage in any structured exercise during the study period. This setup allowed the researchers to directly compare the effects of weight training versus no exercise on the <span>brain health</span> of these individuals. 

<h2>Can This Help Reverse Early Cognitive Decline? </h2>

One of the most hopeful findings of the study was that some of the individuals in the weight training group no longer met the criteria for having mild cognitive impairment by the time the study concluded. This suggests that weight training might have the potential to actually change the course of early cognitive decline. 

Researchers believe this happens through several ways: by reducing harmful swelling in the brain, by improving how the body uses sugar which can affect brain health, by increasing helpful substances in the brain that support the growth and survival of brain cells, and by improving blood flow to the brain, which is essential for it to function properly. 

Looking ahead, researchers are planning to delve deeper into the specific biological processes at a molecular level that explain how weight training has these protective effects on the brain. They also aim to identify specific markers in the body that could help us understand who might benefit most from this type of exercise and what the ideal exercise routines might look like for different individuals.
