Dementia may start in the feet, not the brain. A neurosurgeon warns about the link between walking and cognitive health.

“Dementia may start in the feet, not the brain.”

According to the doctor, physical inactivity leads to weakening of the muscles of the lower limbs, a process known as sarcopenia, or the loss of muscle mass associated with aging.

This weakening not only compromises mobility but also brain function. Active muscles release neurotrophic factors, such as BDNF (brain-derived neurotrophic factor), substances essential for the protection and regeneration of neurons, especially in the hippocampus, the area responsible for memory.

The link between walking pace and cognitive decline
Research supports this hypothesis. A study published in the journal Neurology in 2020 showed that people with a slower walking pace have, on average, smaller brain volume and a higher risk of cognitive decline.

Walking is not a simple physical activity. It involves complex coordination between:

the frontal lobe,
the cerebellum,
the spinal cord,
the proprioceptive system.

This coordination stimulates neuroplasticity, or the brain’s ability to create and reorganize neural connections.

How to reduce the risk of dementia through exercise
The specialist recommends some accessible but effective habits:

Walk every day – at least 30 minutes at a brisk pace;
Balance exercises – walk in a straight line or stand on one leg;

Dual-task walking: combining walking with a cognitive activity, such as conversation or mental calculations;
Leg strength exercises: to maintain muscle mass;
Reduce sedentary lifestyle: get up from your chair and move around every hour.

The doctor’s message is clear: if mobility decreases, the brain may suffer over time.

It’s never too late.
An important point emphasized by the specialist is that the benefits of exercise are evident even when physical activity is started at an advanced age. People who adopt an active lifestyle around the age of 60 can significantly reduce their risk of dementia.

Furthermore, a balanced diet, rich in proteins, supports muscle mass and indirectly contributes to protecting cognitive functions.

A healthy brain through regular exercise.
Preventing dementia isn’t limited to mental exercises like Sudoku or crossword puzzles. Regular physical activity plays a key role in maintaining brain health. Movement supports cognitive function, prevents falls, and helps maintain independence in old age.

The experts’ conclusion is simple: for a sharp and active brain even at 80, it all starts with taking care of your mobility. Trained legs can mean a stronger brain.

No, dementia does not “start at the feet.”

The statement that dementia starts in the feet is an oversimplification and can be misleading.

Dementia affects the brain. However, reduced mobility, a slower gait, difficulty with balance, or muscle weakness can sometimes occur before or alongside cognitive decline.

Walking isn’t just about moving your legs. To walk safely, the brain coordinates attention, orientation, balance, vision, reflexes, and muscle control.

Therefore, any persistent changes in gait should be discussed with your doctor, especially if accompanied by increased forgetfulness, confusion, repeated falls, or difficulty performing normal daily activities.

What research has shown about gait and the brain:
Some studies have found that the simultaneous decline in walking speed and cognitive function is associated with brain changes, including a reduction in brain volume and damage to small blood vessels in the brain. It’s important to understand, however, that this is an association, not proof that slow walking causes dementia.

A person may walk more slowly for a variety of reasons: knee or hip pain, arthritis, vision problems, neuropathy, Parkinson’s disease, side effects of certain medications, anemia, heart disease, stroke, or fear of falling.

But one thing is certain: regular physical activity is beneficial for both the body and cognitive health.

Why Exercise Is Good for the Brain
Regular exercise promotes circulation, heart and blood vessel health, sleep, mood, balance, and independence.

It also helps control factors that increase the risk of cognitive decline, such as hypertension, diabetes, being overweight, and a sedentary lifestyle.

Strength training is important in old age because it helps maintain muscle mass and reduce the risk of falls. Healthy muscles don’t “cure” dementia, but they promote mobility, independence, and quality of life.

How Much Exercise Is Recommended
For most adults, including older adults who can exercise safely, the general goal is at least:

150 minutes of moderate physical activity per week.

This can mean about 30 minutes of brisk walking, five days a week. It doesn’t have to be all at once. The exercise can be broken down into shorter sessions, such as three 10-minute walks a day.

For people who have been sedentary for a long time, the most important thing is to start gradually. Simple habits for strong legs and an active mind:
Walk every day, at a pace suited to your physical condition.

Get up from your chair regularly and avoid sitting for extended periods.
Perform light strengthening exercises: chair lifts, partial squats with support, climbing a few steps, or exercises recommended by a physical therapist.
Work on your balance, but only in safe conditions: near a wall, on a stable chair, or with someone nearby.

Poor stability, but if you like it, joint pain or balance problems.
Mentine legatura cu oamenii din jur. Social and nighttime activity, a balanced diet, and blood pressure control are important aspects of your health.
Consume sufficient protein and a variety of foods to support muscle mass, and adapt your diet to recommended medications if you have rhinitis, diabetes, or other conditions.
When to Seek Medical Assistance:
A medical evaluation is important if the appliance doesn’t crash or crashes quickly, as it has several days before;
dizziness or repeated falls;
tremors, stiffness, or sluggishness in a picior;
confusion, disorientation, or memory problems that affect your life;
hardness in the mouth, air in the lips, aches or pains during exertion.
Conclusion
A sea has never had automatic problems, and the picioarele are not the place where “ncepe” boala.

The body and creativity work together. The balance of mobility, physical strength, balance, and health can support independence and help reduce the risk of cognitive decline.

For healthier thinking, there’s no magic solution. It’s in your heart, and you should be consistent: proper care, sleep, a balanced diet, medical checkups, and an active lifestyle—everything physical, everything social.
