Researchers studying the risk factors for dementia appear to have disproved the notion, 'age is just a number.'

Researchers from China discovering a person's biological age has a substantial impact on determining whether they might develop Alzheimer’s disease or another type of dementia, regardless of having a younger chronological age.

There are two methods for measuring a person’s age: their chronological age – which is simply how many years they have lived – and their biological age – which refers to the condition of their body relative to their actual lifespan. age of your cell components and body parts .

As cells age, they accumulate more wear and tear. Cells that are old or damaged increase the likelihood of cognitive deterioration and conditions like chronic diseases in individuals. cancer .

Although you cannot influence your chronological age, adopting a Mediterranean diet, staying physically active, managing stress levels, and maintaining good nutrition can assist in keeping your biological age younger or even reduce it further.

By examining over 14 years of health records from approximately 280,000 individuals in the UK with an average age of 57, researchers discovered that participants who went on to develop dementia showed signs of being biologically older—by about 10 years—at the start of the study, as indicated by markers related to their blood composition and organ functionality.

Individuals with the highest biological age were approximately 30 percent more prone to developing dementia compared to those in the youngest group.

Although the researchers utilized sophisticated algorithms to determine individuals' biological ages, The News Pulse has disclosed a 24-question survey designed to uncover just how mature your body truly is—regardless of the number of years you have lived.

Experts suggest that a favorable outcome is having a biological age that is somewhat lower than one’s chronological age, which refers to the total years an individual has lived.

Experts from NOVOS located in New York City have developed an artificial intelligence-driven tool designed to estimate someone’s biological age without relying on blood tests.

The examination is complimentary, painless as it uses no needles, and is derived from data collected among 47,000 individuals from America and Europe.

Individuals who take the test initially respond to queries about their ethnic background, gender, educational attainment, and income level.

The examination additionally requests participants to provide their arm circumference, as this metric can indicate muscle mass and fat distribution. Should this information be unavailable, individuals are informed that they may use the U.S. average measurement of 13 inches instead.

Additionally, there is a query about blood pressure wherein participants utilised information from the American Heart Association to approximate their blood pressure when unaware of their actual levels.

A desirable level would be 120 over 80 millimeters of mercury (mmHg), whereas an undesirable measurement falls between 120 and 129 mmHg with a reading under 80 mmHg for the bottom number.

They are questioned regarding their lifestyle, such as whether they have gained weight recently, how much alcohol they consume, and if climbing stairs leaves them winded.

The instrument proceeds to examine the information and uncovers a biological age, which is subsequently dispatched to users through their emails.

The online calculator provides only an estimation since determining a person's biological age requires thorough testing.

In the research conducted by the Chinese scientists, the group ascertained people’s biological ages By assessing lung capacity, blood pressure levels, and cholesterol, along with various other blood markers such as mean corpuscular volume and leukocyte count.

At the beginning of the study, the typical chronological age was approximately 57 years old, whereas the mean biological age was roughly 45 years old.

Upon splitting the participants into four categories according to their biological age, scientists discovered that individuals who exhibited the highest level of biological advancement were approximately 30 percent more prone to developing dementia compared to those in the youngest category.

Individuals with a greater biological age were typically older, male, current or past smokers, and carriers of the APOE 4 gene, which is associated with an increased risk of developing Alzheimer’s disease.

The scientists used two distinct algorithms to determine people's biological ages.

Firstly, referred to as KDM-BA, this method employs a machine-learning algorithm that contrasts nine health indicators of an individual—including factors like blood pressure, cholesterol levels, and pulmonary functionality—with the corresponding statistics from the general populace.

If biomarker indicators suggest they are worse off compared to their actual age, then these individuals are assigned an advanced biological age.

The alternative algorithm called PhenoAge calculates biological age through a combination of 10 measures—such as indicators of inflammation and metabolic factors like glucose—and integrates these with chronological age within a formula designed for predicting mortality risk.

Higher biological age scores computed by both measures were associated with reduced volume across most areas of the brain, particularly in the hippocampus, which is crucial for memory processing and storage.

People who were found to have a greater biological age according to the KDM-BA algorithm showed a thinner cerebral cortex, which is the brain’s outer layer, across 40 different areas of the brain. These regions play significant roles in memory formation and decision-making processes.

People who have a greater biological age according to the PhenoAge algorithm show thinner cortices in 45 different parts of their brains. The most notable reduction occurs in areas that handle sensory processing and regulate emotions.

The research, which appeared in the journal Neurology, identified between 36 to 40 areas of the brain showing signs of thinning, linked to a heightened likelihood of developing dementia.

This reduction in cortex thickness was responsible for about eight per cent of the increased risk linked to faster biological ageing, suggesting it has a considerable – though not sole – impact on cognitive deterioration.

Although the reduction of brain tissue can increase the likelihood of developing dementia, other age-associated elements such as vascular harm or protein accumulation probably account for most of the associated risks.

Although individuals who subsequently developed dementia were, on average, 65 years old chronologically when the study began—compared to 57 for those who remained free from dementia—their average biological age using one measurement method was 55, as opposed to 45 for those without dementia.

Dr Yacong Bo, a researcher from Zhengzhou University in China, stated: "These alterations in brain structure account for some—but not all—of the link between an advanced biological age and dementia."

'These findings back up the theory that an increased biological age might play a role in the onset of dementia through alterations across various regions of the brain.'

Nevertheless, for those aiming to rewind the clock, decreasing stress levels has the potential to reduce your biological age by a matter of days.

Experts likewise contend that minor adjustments to one's eating habits, physical activity, and rest can contribute to lowering an individual's biological age.

In recent times, biohacking for longevity has become increasingly popular, with enthusiasts attempting to decrease their biological age in order to extend their lifespan and prevent conditions like heart disease.

The renowned biohacker Bryan Johnson, aged 47, asserts that his lung function corresponds to someone who is 18 years old. He further states that his cardiovascular system resembles that of a person at 37, his dermal health matches up with an individual of 28, he experiences gingival inflammation typical of someone around 17, and maintains nocturnal erections akin to those of a young adult.

Doctor Bo stated: "Given the increasing global influence of dementia, recognising risk elements and adopting preventative actions is crucial."

'Although none of us can alter our chronological age, we have the ability to impact our biological age via elements like dietary choices and physical activity.'
