Interesting finding: The brain uses tips against aging

Aging is an inevitable process of life, but our brains use some tips to help the body slow down this aging rate.

As we age, our brains rearrange their own structures to slow down the cognitive response, compensate for energy, which increases the level of concentration."The results show that older people compensate for cognitive decline by stimulating and increasing concentration , " said researchers from the University of Bochum in Germany.

Researchers have asked 17 children and 10 elderly patients to voluntarily participate in experiments to arrange circles with different colors into different categories. Both groups of young and old volunteers have the same classification of circles. However, in the elderly, they find it difficult to categorize circles of different colors and shapes.

Elderly people will be reduced to the rate of reaction and awareness to compensate for the concentration.(Image source: escientificnews).

"There are two main strategies that we use to categorize different things. One is to look at all and find the differences. The other is to start classifying each one individually. Older people will feel more difficult to switch from one strategy to another, ' explained researcher Sabrina Schenk.

Researchers show that the brains of older people tend to use more individual classification . They will focus on small details, look more closely and pay more attention to selection than young people. The brain is the most important and complex organ in the human body, but over time, the human brain will age.

From 20 years of age onwards, the weight of the human brain decreases by 10-20%, causing the brain to shrink, most visible at the frontal, parietal and temporal lobes. Decreased brain volume reflects the number of neurons getting less and less. This leads to weakening of nerve function. The weakening of nerve function is not caused by a specific disease. The cause of this weakness is due to age, which causes blood vessels to age, the contraction of the heart is not as strong as before, so the blood flow to the brain is reduced, oxygen to the brain is also worse.

Another reason is the aging of nerve cells with age . In the elderly who suffer from a number of diseases such as hypertension, diabetes, cardiovascular ., the aging process of the nervous system will be faster, stronger than normal people.

The brains of older people tend to use more individual classification.

By puberty, the brain contains almost full neurons for life. But in some areas, to continue to develop new neurons, some specialized immune cells are needed to keep the brain safe by eliminating dead or dysfunctional cells.

Since two decades ago, scientists have discovered that immune cells release important molecules called TAM receptors . Two of the TAM receptors are named Mer and Axl , which help immune cells called macrophages "collect garbage" from more than 100 billion dead cells made by the body every day.

"We discovered receptors on the immune cells in the brain that are essential for both healthy and injured states. These receptors may be the potential target for treatment of degeneration." Neurological or neurological disorders caused by inflammation, " said biology professor Greg Lemke of the Salk Institute.
