These results, in which they studied nearly 11,000 healthy adults, open the door to personalized interventions to slow their degeneration, the research led by Chinese scientists, published in Nature Aging reveals.
In the study, the scientists observed that the changes were not linear with increasing age, but showed three peaks with abrupt changes, related to metabolic changes at 57 years of age; cognitive and movement losses at 70, and neuronal fragility at around 78.
The researchers argue that nowadays, exceeding 90 years of age and reaching centenary is becoming more and more common. But the point is not to live longer, but to maintain lucidity and quality of life as we age.
One of the factors preventing this is neurodegenerative diseases, such as Alzheimer’s, for which age is the main risk factor. The number of cases doubles every five years after the age of 65, according to official data.
