After 40: What are the three ages at which cerebral aging is accelerated

The question before the effects of Aging in the functioning of the brain He has a scientific response: there are three key moments and the first begins before the age of 60. A group of researchers from First hospital affiliated to the University of Zhengzhou, in Chinathese transformations occur mainly at 57, 70 and 78.

Experts underline that These ages represent crucial moments to implement strategies aimed at preserving brain health for longer. Among the proteins analyzed, the Brevican (Bcan) Aroused special attention, which is associated with conditions such as dementia, strokes and motor disorders. Another key protein, known as GDF15It is also linked to disease -related diseases.

After 40, the ages at which cerebral aging increases

The analysis, based on blood plasma samples of more than five thousand British between 45 and 82 years, highlights an alarming fact: In 2050, the world population over 65 will exceed 1.5 billion people.

“These findings help fill crucial gaps in the knowledge of the molecular mechanisms of cerebral aging, With important implications for the development of biomarkers and personalized therapeutic objectives for age -related brain disorders, ”the researchers emphasized.

In September, a team of Stanford noted that the effects of aging, such as slower metabolism, the appearance of wrinkles in the skin and the increase in vulnerability to diseases, They reach significant peaks between 44 and 60 years.

Michael Snyder, professor of genetics at Stanford, explained: “People assume that all gradually age. However, most of the changes are not linear” Specialists recommend that people in this age strip prioritize a balanced diet and perform frequent physical activitymeasures that can mitigate the effects of accelerated aging in these key decades.

The ages at which the body presents a more accelerated aging, according to the study

Although aging changes usually develop progressively, An research at Stanford University revealed that body aging has two significant acceleration moments: at 44 already 60 years. According to the study, published in the journal Nature Aging, in these stages “dramatic” alterations occur in the functioning of the human body.

“Not only are we gradually changing over time; There are dramatic changes, ”said Michael Snyder, a professor of genetics at Stanford and the main author of the study. The study analyzed 108 participants, examining around 135,000 molecules and microorganisms present in their bodies. The researchers identified that the most perceptible alterations occur in two specific moments: upon reaching 40 years and when reaching 60 years.

Body impacts at each stage

In the first group, 44 -year -old individuals experienced molecular transformations related to the lipid metabolism, the consumption of caffeine and alcohol. For its part, In the 60 -year group, Lchanges were linked to Carbohydrate metabolism, renal function, immune regulation and cardiovascular conditions.

“When observing the groups of molecules with greater changes in quantity, they discovered that these transformations occurred with greater intensity in two periods of time: when they reached 40 and a few years, and when reaching 60 years,” concluded Stanford’s article.
