American scientists have discovered why some people over 80 years old maintain excellent memory and clarity of thought. The study showed that so-called superagers have more new nerve cells formed in the hippocampus, which may protect the brain from age-related changes and dementia.
The brain of most people changes with age, which worsens their cognitive abilities. However, there is a special group of people over 80 years old whose brains do not succumb to aging - and now scientists know why.
A study by American researchers showed that superagers have more new neurons formed in the hippocampus.
This may explain their better memory and protection against dementia, including Alzheimer's disease.
Scientists hope to develop a treatment based on this discovery that supports cognitive abilities. The brain of most people changes with age, which worsens their cognitive abilities. However, there is a special group of people over 80 years old whose brains do not succumb to aging - and now scientists know why.
Previous studies have shown that so-called superagers experience slower brain shrinkage, their volume decreases to a lesser extent, and inflammation occurs less frequently. A study published in the journal Nature also showed that superagers form more new nerve cells than other elderly individuals, which helps keep their brains healthy.
According to the editorial, the discovery of the mechanism that allows the brain to maintain youth longer could be an important step in the fight against Alzheimer's disease and other age-related memory disorders. Scientists are getting closer to understanding how to maintain cognitive health in old age and slow down the natural aging of the brain.
