The brain does not progress gradually: its deterioration begins before we think about it and suddenly
propagandaA new study indicates that the human brain It does not progress gradually and dangerousBut it happens Surprising aging In different periods of life. The research, whose results in the scientific journal “PNAS” are based on an analysis of brain image data for more than 19,300 people between 18 and 90 years.
When explaining the results, the researchers write: “The brain networks do not become unstable throughout life, but these changes have an unpredictable tendency, almost, since the fourth decade of life, cracked signs of brain aging appear.” According to them, the human brain is tested A quick aging operation is about 44 years oldIndeed, 67, the process becomes more dense, but finally, about 90 years old, aging is stable.
Energy deficiency in brain cells after 40 years
Previously, some investigations suggested that the aging process could be linked to A decrease in the necessary energy To transmit nerve messages in the brain. The new results indicate that this low energy starts about 40 years and may be associated with it Insulin resistance.
After this age, the brain cells continue to work, but they need higher levels of insulin Regulating blood sugar. “For this reason, alternative fuel supplies during this sensitive period can help improve brain function.”
This fuel can be provided through ketones, which were entered into this study as a possible preventive factor. Stony Brook University says the ketones Type of brain fuel Neurons can be consumed without insulin.
Hope in the treatment of Alzheimer’s disease
In one of the experiments conducted in the same study, the researchers examined the effect of ketones compared to glucose. The results show that the ketones They were able to install the deteriorating brain networks. These results can lay the foundations for a new approach to prevent cognitive deterioration caused by increased age, as well as diseases that harm the brain cells, Like Alzheimer’s.
“It is a fundamental change in our approach Preventing the aging of the brainHe says, “Boutefand Antal, the main researcher of the study. Instead of waiting for the symptoms of cognitive deterioration, we can identify people at risk through the signs of nervous army and interfere during the same sensitive period,” says Boutend Antal, the main researcher for study.
