Researchers have uncovered a healthy aging blood test which helps diagnose Alzheimer’s disease and dementia. The findings came from a seven-year collaborative study at King’s College London, Karolinska Institutet in Sweden and Duke University in the U.S.
Researchers used a process called RNA-profiling to compare and measure gene expressions in human tissue samples. Researchers found activation of 150 genes which mark good health in those 65 and older. By creating a reproducible formula for healthy aging, researchers were able to determine how well a person will age in comparison to others born in the same year.
Additionally, researchers found that individuals have a biological age which differs from their chronological age. A low score in biological age was related to cognitive decline, meaning a healthy aging blood test could reveal a person’s risk of Alzheimer’s disease or dementia.
Biological age was not associated with a person’s risk of heart disease or diabetes which reveals that lifestyle choices are independent.
Researchers believe they have developed the first accurate healthy aging blood test which reveals the rate at which our bodies truly age. Aside from this finding, healthy aging blood tests could better find suitable donor matches for older organ transplant patients.
What is lacking from the findings is how to increase a person’s biological age thus reducing their risk of Alzheimer’s or dementia.
Lead author Professor James Timmons said, “Given the biological complexity of the ageing process, until now there has been no reliable way to measure how well a person is ageing compared with their peers. Physical capacity such as strength or onset of disease is often used to assess ‘healthy ageing’ in the elderly but in contrast, we can now measure ageing before symptoms of decline or illness occurs. We now need to find out more about why these vast differences in ageing occur, with the hope that the test could be used to reduce the risk of developing diseases associated with age.”
Our body goes through many changes as we continue to age. Not only does appearance change with aging, but bodily functions change as well. Our hearts are not as strong, our vision is not as sharp and our bones become weaker as well – just to name a few. Other effects of aging on the body and mind include:
Aging doesn’t have to be a burden, and you don’t simply have to succumb to the effects of aging. With these helpful tips you can age and live healthily. The first step to healthy aging and living is to recognize that it’s never too late to start healthy habits, and you’re never too old to start reaping the benefits of healthy habits. It doesn’t matter if you’re 60, 70 or 80 and older, these tips to healthy aging can provide you with many more years to come.
Although causes of dementia and Alzheimer’s disease are still unknown, every day we learn more and more about these mental illnesses. With the help of ongoing research, tips have been developed which help to improve cognitive function and thus offer better protection against dementia and Alzheimer’s disease. Some tips include:
Eating a healthy diet, too, can be effective in preventing dementia and Alzheimer’s disease. Below are some foods shown to boost cognitive ability and brain health.
In a perfect world we would all never age, but unfortunately until the fountain of youth has been discovered we continue to age. Things like wrinkles, fine lines, and spots on the skin all seem to appear with each passing year and although you can’t stop aging you can take steps to age more slowly. Continue reading…
Let’s be honest for a moment, no one wants to grow old. In a perfect world we’d be 21 forever, but unfortunately Mother Nature has a different plan for us. And so every year we celebrate another birthday, our skin loosens and our abilities start to diminish. No one said growing old would be fun, but even in our older age we can look back on a life filled with memories. Continue reading…
