Many of us might already know that dementia is one of the main reasons for dependency and disability among older adults all over the world. Studies show that almost 10 million individuals get affected by dementia each year. However, the common belief is that not keeping the brain active is the leading cause of this disease. Dr. Arun L. Naik, an influential neurosurgeon from AIIMS or All India Institute of Medical Sciences, India, points out that the beginning of dementia can be traced to our legs. In this article, we will explore the strong correlation between leg health and dementia and also list out some of the best ways of escaping the development of the problem.



Understanding Dementia


Dementia is an umbrella word that is used to signify a range of progressive neurological conditions such as Alzheimer’s or vascular dementia. These diseases negatively affect our brain cells, causing cognitive impairment. It can severely impact the quality of daily life as it creates memory decline and behavioural problems. Support by caregivers and early diagnosis can help a lot in dealing with dementia. Medical interventions will also be required.



“Dementia Starts in Your Leg”


In an Instagram video titled “Dementia starts in your legs- here’s how”, Dr. Naik said: “Did you know that dementia starts in your legs? Physical inactivity weakens your leg muscles, leading to sarcopenia, a loss of muscle mass. But here is the shocking part. Studies show that weak legs can speed up cognitive decline and increase dementia risk. Because active muscles pump out powerful chemicals that boost brain health. These chemicals are called brain-derived neurotrophic factors, BDNF, which increase connections in your memory area called the hippocampus. Strong legs mean strong balance and zero falls as you age. Falls are dangerous after the age of 65.”



He referred to a study published in National Library of Medicine in the year 2020 to drive his point home. The study found a strong correlation between slower walking speed and smaller brain volume in older adults. This poses an increased risk of cognitive decline. Dr. Naik says that, “Walking is not just a physical task, it’s a full-brain workout.”



How Walking Improves Brain Health?





He also reminded us that if you are seeing a change in the walking style of a person, consider that as a warning from the brain. A change in gait, pace or even balance often precede memory symptoms by years.
