Maintaining muscle mass may play a key role in preventing dementia, as aging often leads to pronounced changes such as decreased mobility and loss of strength. Age-related muscle loss is an inevitable event that affects the physical as well as the mental state of humans. New research suggests maintaining skeletal muscle can be key to supporting cognitive functions and may even play a role in preventing dementia.

A study presented at the Radiological Society of North America's annual meeting revealed that elderly patients with lower skeletal muscle mass had about a 60 percent higher risk of dementia. Skeletal muscle forms one-third of our body weight and tends to atrophy with age, and that muscle decline has broad-ranging effects, from increased physical frailty to potential cognitive decline, said Dr. Marilyn Albert, a professor of neurology at Johns Hopkins University.

The researchers measured the size of the temporalis muscle, which is part of the jaw region, as a marker of overall skeletal muscle health. Their findings showed a clear link between reduced muscle mass and an elevated risk of dementia. This connection highlights the urgent need to prioritize muscle maintenance, particularly as age-related conditions like sarcopenia and anabolic resistance pose additional challenges.

Why Muscle Maintenance Becomes Harder With Age

This begins around the age of 30. Then, there is a loss of 3-5% muscle mass every decade. But the decline is faster for those aged 50. Contributing factors include sarcopenia, an umbrella syndrome causing progressive loss of muscle and bone mass. And there is anabolic resistance - reduced skeletal muscle synthesis of protein, making it difficult to build and maintain muscle in the presence of exercise.

Despite these challenges, strength training and endurance exercises remain effective strategies to rebuild muscle and enhance overall health.

5 At-Home Strength Exercises to Build and Maintain Muscle

Fortunately, you don't need to join a gym to maintain muscle strength. Here are five simple yet effective exercises into your routine to help preserve muscle mass and support cognitive health.

1. Calf Raises

• Stand with feet shoulder-width apart. Lift onto your toes, keeping your core tight. Hold for 1-2 seconds, then lower back down. Repetitions: Perform 15 reps for 2-3 sets.
• Benefits: Improves lower leg strength and balance.

2. Plank

• Lay face-down and position forearms on the ground. Stretch legs back and curl toes under.
• Press your body against the ground, with it straight and core tight.
• Repetitions: 15-20 seconds holds for 2-3 sets.
• Benefits: Strengthens the core, shoulders, and back muscles.

3. Squat Into Chair

• Stand a half step away from a chair.
• Lower into a squat until you nearly touch the chair, extending arms forward.
• Return to standing, bringing arms back in.
• Repetitions: Repeat for 2-3 sets of 10-15 reps.
• Benefits: Strengthens the muscles in the legs as well as helps to better your posture.

4. Elevated Pushups

• Position hands on a wall with feet shoulder-width apart.
• Perform a push-up and lower toward the wall, then return to beginning.
• Repetitions: Do 2-3 sets of 10-15 reps.
• Benefits: Stretches chest, arms, and shoulders with minimal strain.

5. Wall Angels

• Stand with your back against a wall, pressing hips, shoulders, and elbows into the wall.
• Push your arms up into a "Y" shape and then back down.
• Repetitions: Do 10-15 reps for 2-3 sets.
• Benefits: Helps to improve shoulder mobility and posture.

Additional Tips for Muscle Maintenance

Safety and effectiveness are guaranteed by following the given tips:

1. Always warmup at the start and cool down at the end to avoid being injured.

2. Maintain proper posture and control during every movement.

3. Progressively increase weights or resistance bands as strength is enhanced.

4. Complete each movement slowly in order to achieve control and to avoid straining.

5. Give your muscles time to recover and rebuild between sessions.

Walking is said to be one of the best exercises. Not only is it an easy and accessible exercise, but it can be done anywhere and also does not need a lot of equipment. Many people aim for 10,000 steps a day as a sign of good health. But should you take one long walk, or multiple short ones? A new study has answered this question.

New research suggests that a single, longer walk each day is better for your heart than breaking up your steps into many short strolls, especially if you don't exercise regularly.

The study, published in Annals of Internal Medicine, found that walking for at least 15 minutes without stopping is ideal. This longer, steady pace, which is about 1,500 continuous steps gives your heart a much better workout.

Longer Vs Shorter Walks: Which is Better?

Researchers tracked the walking habits of over 33,500 adults in the UK who walked less than 8,000 steps a day. After tracking their health for eight years, the findings were clear:

Lower Heart Risk

People who consistently walked in longer, uninterrupted stretches had a lower risk of heart problems compared to those who only took short, quick bursts of steps.

Why Are Longer Walks Better For Health?

Even among the least active group (those walking under 5,000 steps daily), taking longer walks made a major difference. Their risk of heart disease and early death dropped significantly.

The researchers explain that most people focus only on the number of steps they take, but not the patterns. They suggests that even inactive people can boost heart health by changing their habits to walk for at least 10–15 minutes at a time.

Should People Focus More On How They Walk Or How Much?

Many people aim for 10,000 steps a day, but that number actually came from an old pedometer advertisement, not science. While experts agree more steps are generally good, this study emphasizes that how you walk matters more than just the total step count.

The researchers suggest that simple changes, like setting aside time specifically for a long walk, could make a big impact on heart health.

The NHS still recommends getting 150 minutes of moderate activity like brisk walking, each week, and ideally it should be spread out. For older adults, moving every day, even with light activity around the house, is key.

It's important to know that while the study shows a strong link between longer walks and better health, it doesn't definitively prove that walking directly causes the improvement.

However, health experts agree exercise is vital. They explain that you might find it hard at first, but it will get easier as your body adjusts. Even small improvements contribute to a healthy heart.

What Are Some Safety Tips for Walkers?

While walking is generally a safe activity, accidents can happen, especially if you like to walk alone. To stay safe while walking,

Be Visible

Wear bright, reflective clothing or carry a flashlight after dark or in dim light so drivers and others can easily spot you.

Stay Alert

Focus on your immediate surroundings; avoid distractions like your phone or headphones to always know what's happening around you, especially traffic.

Use Paths

Walk or bike only on marked paths, lanes, or sidewalks, and cross streets at designated crosswalks where vehicles are expecting pedestrians.

Donald Trump health has become a heated topic of debate and the concerns around his health has resurfaced after a photo from his Kuala Lumpur visit on Sunday, October 26, went viral. He was spotted with swollen ankles. The photo that went viral is from a meting of the Association of Southeast Asian Nations (ASEAN), which kicked off his six-day trip.

The pictures of his swollen ankle have flooded on social media and people are saying that his ankle is seen to be extremely swollen. As per experts, this happens due to chronic venous insufficiency, which is a condition Trump had earlier announced to be suffering from.

Chronic venous insufficiency occurs when the veins in the legs have trouble sending back to the heart. This causes blood to pool and creating high pressure. This is usually caused by damaged or weakened valves in the veins and is characterized by symptoms like leg swelling, aching, and heaviness, which improves with elevation. Risk factors include age, a history of deep vein thrombosis, and prolonged periods of sitting or standing.

However, Trump's latest physical test says something else. The White House physician Sean P Barbabella declared that the president "remains in exceptional health, exhibiting strong cardiovascular, pulmonary, neurological, and physical performance". Barbabella also stated that his "cardiac age was found to be approximately 14 years younger than his chronological age".

Trump's Legs Could Also Reveal That He Had A Stroke

As per a "Physical Therapist", who posts videos on Instagram by the username @epistemiccrisis with 74.2k followers, Trump also had his peroneal nerve paralyzed. He explains, "The deep branch of common peroneal nerve, which supplies a muscle known as the tibialis anterior, which blends your foot up toward your head when you walk. This is known as dorsiflexion. If this nerve is paralyzed, you would get a foot drop."

However, he notes that this can be easily remedied with a brace, called ankle foot orthosis or AFO. He said that the president was most likely wearing it as the outline of the posterior portion of "what looks like an AFO" could be seen through his pants.

Concerns On Trump's Health

Previously, the same "Physical Therapist" claimed that President Trump had a stroke. This is because he had difficulty walking in a straight line. In fact, a 2021 study published in journal Healthcare notes that stroke is a major cause of disability worldwide and balance impairments are common disabling factors in patients with stroke, which could lead to falls.

However, as per the official medical records of the president, no such strokes were mentioned. His medical report pronounced him in "excellent health". The examination was done at Walter Reed National Military Medical Center. The report also emphasized that Trump maintains a "demanding daily schedule without restriction". Not only that, the report has gone so far to declare Trump's cardiac age as 14 years younger than his actual age after an electrocardiogram.

Dr Peter Attia, physician, and researcher known for his work in longevity medicine believes that there is a correlation between your grip strength and dementia onset risk and dementia mortality.

Dr Attia says, "My best explanation for this is that grip strength is itself a proxy for overall strength. The type of strength we are talking about here is acquired, not inherited. You had to do a bunch of work to get it, and it is the work you did that is actually what's protect your brain."

He says that women who are over 40, must be able to hand on a bar for a minute and a half, and for men, it is two minutes. The key is that you are supposed to be able to carry 75% of your weight, he says, in an interview with CBS News' 60 minutes.

Is There Any Truth In The Claim That Grip Strength Has A Correlation With Dementia?

As per a 2021 study published in journal Frontiers in Aging Neuroscience, titled Grip Strength and the Risk of Cognitive Decline and Dementia: A Systematic Review and Meta-Analysis of Longitudinal Cohort Studies, loss of grip strength and cognitive impairment are prevalent in the elderly, and they may share the pathogenesis in common.

The study found that poorer grip strength was in fact associated with more risk of cognitive decline and dementia. The subgroup analysis within the study also indicated that people with poorer strength had more risk of Alzheimer's disease and non-AD dementia.

But why does this happen? Lower grip strength is a marker for overall muscle mass, general health, and is linked to the health of the brain and its blood vessels. This link is also connected to other factors like vascular health, cognitive decline, and physical activity, as low grip strength can be a symptom of poor overall physical and metabolic health.

How Is Lower Grip Strength Is Linked To Dementia?

Indicator Of Overall Health: Grip strength reflects the health of entire body, this is why a lower grip strength is an indicate of lower muscle mass, and general poor health.

Vascular and brain health: Since there is a connection between muscle strength, blood flow, and brain health, thus lower grip strength is associated with a higher risk of vascular dementia and a greater volume of white matter hyperintensities in the brain.

Poorer grip strength is associated with lower cognitive function, such as fluid intelligence and prospective memory. This suggest a link between the body's physical capabilities and the brain's cognitive abilities.

A different study published in 2022, where 40,000 participants from the UK Biobank were studied found that greater grip strength was associated with better cognitive functioning, higher life satisfaction, greater subjective well-being, and reduced depression and anxiety symptoms while controlling for numerous demographic, anthropometric, and socioeconomic cofounders.

The study also found that grey matter volume of subcortical region also correlated with better mental health and considerably mediated their relationship with grip strength.
