By the time of diagnosis, the process appears to be irreversible.<\/p>\n<p>The new research in\u00a0<em><a href=\"https:\/\/doi.org\/10.1001\/jamanetworkopen.2022.19926\">JAMA Network Open<\/a><\/em>, however, identifies muscle mass as a modifiable factor that could potentially be used to decrease the risk of developing the condition, before it\u2019s too late.<\/p>\n<p>The work highlights the importance of muscle mass as an independent factor linked with rapid cognitive decline.<\/p>\n<p>\u201cLow\u00a0<a href=\"https:\/\/www.futurity.org\/exercise-strength-training-muscle-mass-2729472-2\/\">muscle strength<\/a>\u00a0has been recently associated with greater risk of dementia, but little is known about a possible link between muscle mass and cognition,\u201d says lead author St\u00e9phanie Chevalier, a scientist in the Metabolic Disorders and Complications Program at the Research Institute of the McGill University Health Centre.<\/p>\n<p>\u201cWith this study, we show for the first time that the presence of low muscle mass is significantly associated with faster cognitive decline and that this association is independent of muscle strength and physical activity level, among other factors.<\/p>\n<p>\u201cThese findings are important because muscle mass is a modifiable factor, meaning that we can do something about it. Exercise\u2014particularly\u00a0<a href=\"https:\/\/www.futurity.org\/resistance-exercise-aerobic-exercise-sleep-2707402\/\">resistance exercise<\/a>\u2014and good nutrition with sufficient protein can help maintain muscle mass over the years,\u201d adds Chevalier, who is also an associate professor at the School of Human Nutrition at McGill University.<\/p>\n<p>Researchers conducted the study using data from the ongoing Canadian Longitudinal Study on Aging (CLSA), which has a rich dataset on body composition and several cognitive tests conducted in person, over three-year intervals, in a cohort of 30,000 people.<\/p>\n<p>The research team asked the question whether having low muscle predicts subsequent cognitive decline in three domains\u2014memory, executive function, and psychomotor speed\u2014in adults aged 65 years and older.<\/p>\n<p>\u201cWe found that having low muscle mass was associated with greater decline in executive cognitive functions over three years, compared to having normal muscle mass, but not with memory nor psychomotor function loss,\u201d says first author Anne-Julie Tessier, a doctoral student with St\u00e9phanie Chevalier at the time of this study who is now a postdoctoral fellow at Harvard University.<\/p>\n<p>\u201cExecutive functions are important in our day-to-day activities and behaviors as they help us sustain attention, organize thoughts, and make decisions.\u201d<\/p>\n<p>Beyond their role in strength and physical functioning, <a href=\"https:\/\/www.theepochtimes.com\/t-muscles\">muscles<\/a> are the reservoir of proteins that serve several important bodily processes. Muscles also secrete molecules that can \u201ctalk\u201d to the brain. It is also known that exercising and building muscle mass, by bringing more blood flow to the brain, can favor executive functioning.<\/p>\n<p>\u201cOur results show that measuring low muscle mass may help to identify people who have greater risk of\u00a0<a href=\"https:\/\/www.futurity.org\/exercise-sweet-spot-cognitive-decline-aging-2674892\/\">cognitive decline<\/a>. We should measure muscle more widely, in clinics, not only in research studies,\u201d says Chevalier.<\/p>\n<p>\u201cFurther work should determine if maintaining or gaining muscle attenuates the cognitive decline with age, and if there is a causal link, what the mechanisms are.\u201d<\/p>\n<p><em>This article was originally published by <a href=\"https:\/\/muhc.ca\/news-and-patient-stories\/news\/ri-muhc-study-shows-association-low-muscle-mass-cognitive-decline\">McGill University<\/a>.
