Scientists Reveal The Four Types Of Aging

Different people age differently. Some look like they’ll always come off 20 years younger, while some bear the years on their bodies. Some people’s hearts stay strong even as they reach their 60s, while some barely reach mid-age before they experience health issues and setbacks, even falling victim to constant infections and inflammations.

And now, a new research may let scientists  take another step towards finally understanding why there isn’t a one-size-fits-all approach to aging for people. 

Through The Years

Per the study, which was published January Monday in the journal Nature Medicine, aging unfolds at different rates and in different tissues, and all this can happen even within a single person. In fact, there are different categories for aging and people fall into distinct ones based on which of their biological systems ages fastest. Scientists are hoping that they can use this information to recommend specific lifestyle changes that a person can do in order to hold off aging inside and outside, as well as create personalized medical treatments for people, someday.

By sorting 43 people into aging categories, known as “ageotypes,” the team behind the research was able to identify four distinct aging types: kidney, liver, immune and metabolic. Depending on a person’s biological system and how it will hold up with age, a person may fit squarely into one category, or meet all of the criteria for all four types. Out of these four ageotypes, 600 so-called markers of aging have also been identified, all of which help predict the functional capacity of a tissue.

"Now, it's going to be a lot more than just four categories. If we [surveyed] 1,000 people, I'm sure we'll find other cardio agers and that category will become better defined,” Michael Snyder, senior author, a professor and the chair of genetics at the Stanford University School of Medicine in California, said. He also stated that there may be more categories that can be revealed under continuous research.

From this, Snyder and his colleagues plan on developing a simple ageotype test that doctors can use to quickly assess a patient’s health status.
