Could This Be the Initial Indicator of Memory Decline?

You may believe that memory loss is the initial indication of dementia — however, what if the earliest alert is something unexpected...

Recent research has revealed a surprising predictor that may manifest years before cognitive symptoms emerge. The exciting news is that this predictor is already detectable on routine medical scans that most seniors undergo.

Overview

• Smaller temporalis muscles could potentially forecast dementia years in advance, providing a non-invasive, cost-effective method to evaluate dementia risk early on.
• Routine brain MRIs already capture this data, eliminating the need for additional scans or procedures for detection.
• Preserving muscle mass through diet and physical activity could play a vital role in safeguarding long-term brain health.

The One Body Part That Could Predict Dementia (It’s Not the Brain!)

Typically, when thinking about early dementia detection, symptoms like memory loss, confusion, and agitation come to mind.

However, these signs usually appear after the disease has already impacted the brain significantly. New research on early memory loss detection suggests that rather than focusing solely on cognitive function, medical professionals should also consider muscle tone, specifically focusing on the tone and size of a muscle located near the brain.

In a recent study conducted by researchers at Johns Hopkins University School of Medicine, muscle loss in the temporalis muscles — situated in the head — of 621 dementia-free seniors was measured using MRI¹. Participants were categorized into groups with large or small temporalis muscles.

Almost six years later, the same participants underwent assessments for cognitive function, dementia, and changes in brain volume. The findings revealed that individuals in the small temporalis group were more likely to have developed dementia since the initial study.

“Our study found that older adults with smaller skeletal muscles are approximately 60% more likely to develop dementia, even after adjusting for other known risk factors,” stated Marilyn Albert, Ph.D., the co-senior author of the study and a neurology professor at Johns Hopkins.

While a 60% increase in the risk of developing this life-altering disease is significant, being aware of this risk in advance could make a substantial difference in your future.

Muscle Loss Testing Is Simple and Offers Hope

Researchers involved in this study highlight that muscle loss testing can be quickly conducted through a standard brain MRI, even if the imaging was performed for other reasons.

“Measuring temporalis muscle size as a potential indicator for overall skeletal muscle status provides an opportunity for skeletal muscle assessment without additional expense or burden in older adults who already undergo brain MRIs for any neurological conditions, such as mild dementia. This study is the first to show longitudinally that skeletal muscle loss may contribute to the development of dementia,” noted Kamyar Moradi, M.D., the lead author of the study and a postdoctoral research fellow at Johns Hopkins University School of Medicine.

In the long term, this test could help patients save time and money, and it could assist in identifying individuals who may benefit from early interventions to halt or slow memory loss.

Preventing Muscle Loss

Other studies have connected muscle health to declining brain health, with the good news being that in many instances, muscle loss can be reversed.

Remaining physically active is one way to prevent muscle loss and promote muscle growth. You don’t need to engage in intense workouts to witness improvements. Activities such as gardening, cleaning, walking, and cycling can help maintain strong and healthy muscles.

Nutrition is also crucial for muscle maintenance. Consuming adequate protein can help sustain and build muscle mass. Additionally, nutrients like choline and B vitamins are essential for muscle health.

Supplements like HMB (beta-hydroxy beta-methylbutyrate) can also be considered as they aid in preserving and rebuilding muscle mass. Clinical studies have shown that HMB supplementation can enhance muscle function, improve physical performance, and reduce the risk of falls — all critical components for healthy aging and sustaining a high quality of life.

If you are concerned about your muscle health, speak with your healthcare provider about undergoing testing for muscle loss and the most effective ways to prevent it.

Summary

A groundbreaking study from Johns Hopkins indicates that diminishing head muscles — particularly the temporalis muscle — might predict dementia years before traditional symptoms like memory loss and confusion manifest. Through routine brain MRIs, researchers discovered that individuals with smaller temporalis muscles had a 60% higher likelihood of developing dementia. This revelation not only offers hope for early detection but also demonstrates how simple lifestyle modifications such as exercise and nutrition could protect both your muscles and your brain.

Frequently Asked Questions

• What is the temporalis muscle?
  It's a significant muscle on the side of your head that aids in chewing — and according to recent research, it could provide insights into future brain health.
• How does muscle size relate to dementia risk?
  Research indicates that smaller temporalis muscles are associated with a 60% higher risk of developing dementia later in life.
• How can I assess my temporalis muscle size?
  It can be measured through a standard brain MRI, even one conducted for other purposes like headaches or mild cognitive concerns.
• Can muscle loss be prevented?
  Absolutely! Regular physical activity and a diet rich in protein can help prevent and reverse muscle loss, even in older adults.
• Does this mean exercise can help prevent dementia?
  While further research is necessary, maintaining muscle health through activity and nutrition may contribute to reducing your dementia risk.
