Five factors accelerate brain aging

Recently, the Journal of the American Medical Association published a new study, found that longevity elderly brain "cortex" twice the thickness of the elderly; cortical thicker, slower brain aging. Researchers believe that understanding the secrets of the longevity of the brain will help us maintain our health and live longer.

Longevity brain has innate advantages


Studies show that the cerebral cortex is like a crumpled newspaper, stretching the area and thickness determines the brain capacity. Cortical thick cognitive, understanding, memory, judgment, calculation, language and other advanced neurological function is good. The researchers conducted a one-year and a half follow-up survey of the cortical thickness of 24 longevity and 12 elderly people and found that longevity elderly cortical thickness, brain capacity, aging has less impact on the brain. Donald, an 89-year-old American, who had a relatively young brain due to cortical thickness, now has easy access to the internet and to school, just as energetic as young people.


Earlier, the Journal of the American Medical Association had published an article that generally speaking, people's brain began to age 30 years old; after 40 years of age, the body's metabolism gradually slows down, the function of brain cells decreased, physical, memory, reactivity Decline, positioning ability, body coordination less than before; 60 years old, the brain at a rate of 15% per year decline. But unlike the average elderly, a U.S. study of 840 longevity clans and offspring found that longevous elderly may have a gene that can repair DNA errors and minor injuries, helping them keep their brains young and healthy.


In addition to the gene to lay the inherent advantages of longevity of the elderly, the child's early growth process may also affect brain development, thus affecting life expectancy. Research shows that children in impoverished areas tend to have small brain capacity, aging affects them more prominently, and their life expectancy is shorter. Beijing Union Medical College Hospital, director of neurology Zhang Zhenxin told the "Life Times" reporter, Beijing Union Medical College Hospital had done a study found that people born in 1921 ~ 1954 reunited in 2003, childhood brain development has not yet completed a good education, with Good nutrition and living environment, good physical fitness, cognitive impairment in old age less. A recent study by the United States also supports this view. Those with a well-educated person have a large cerebral cortex, a large capacity, and a large reserve of knowledge to maintain their energy for a long period of time and to rejuvenate their elderly life.


Five factors accelerate brain aging


Inherent brain strengths or weaknesses can not be changed, but some life factors will accelerate brain aging, thus affecting people's life expectancy, we should strive to avoid.


Diabetes . Geng Tongchao, Director of Department of Neurology, Drum Tower Hospital, affiliated to Nanjing University Medical School, told reporters that diabetes mellitus can make cerebral microvascular sclerosis and blood viscosity increase. The brain is in an ischemic and anoxic state for a long time, which is faster than normal people aging. Hypertension , atherosclerosis and the like can also accelerate brain aging.


Smoking. Geng Tongchao said that when smoking cigarettes, nicotine in the inhalation within 10 seconds to reach the brain and remain active in 20 to 40 minutes, nicotine will damage the blood vessel wall, promote atherosclerosis , reduce cerebral oxygen supply, impair logical thinking ability, speed up Brain aging. A U.S. study shows that each pack of cigarettes loses 2.3 hours of life.


Air pollution. Geng Tongchao told reporters that the brain is the body's largest organ of oxygen consumption, the average consumption of oxygen per minute 500 to 600 liters. There is not enough oxygen in the polluted air to support the work of the brain. It also contains nitrogen oxides, carbon monoxide and other harmful substances that enter the brain through respiration, causing memory loss or depression and accelerating the decline of cognitive abilities in adults.


Overeating. After overeating, the body in order to digest too much food tend to mobilize large amounts of blood and energy to the digestive system, the brain's energy supply less, in an ischemic state, can damage brain cells.


Get used to staying up late. Zhang Zhenxin told reporters that irregular life affect the body's normal circadian clock and metabolism, brain function was disrupted. Staying up will leave your brain in a state of excitement, and without delay, your brain will not be adequately restored, damaging brain neurons. A joint study between Britain and France found that irregular rest and frequent night shifts can impair brain cognition.


The brain is young and has a way


Aging is a necessary process for everyone. When you find that sleep quality is poor and tired easily, it means your brain has started to age. It is time to delay the aging process with a healthy lifestyle.


Focus on children's nutrition. Multi-country research found that breastfeeding can promote the child's intelligent development. "Chinese dietary guidelines" suggest that infants should insist on exclusive breastfeeding within 6 months of age, infant formula is a helpless choice when breastfeeding can not be done; 7 to 24 months of age infants still have to continue breastfeeding, but you can add complementary food, To start with iron-rich mushy food, gradually add to food diversity; children and adolescents should develop good eating habits, not picky eaters, eating regularly, drinking milk every day, enough water, but also often outdoor sports.


Read a book weekly. Zhang Zhenxin pointed out that life is rich in content, brain use, slow brain aging, reading and thinking of the brain will stimulate neuronal synaptic enrichment, anti-aging process. Often reading books have a high cognitive reserve, the brain can play a role in aging buffer, slow down the aging rate, so that the brain more resistant to dementia and other diseases.


Exercise twice a week for 30 minutes. Geng Tongchao told reporters that out twice a week, each time 30 minutes Tai Chi, brisk walking or other outdoor activities, not only conducive to cerebral blood circulation, but also on the control of cholesterol, regulate blood pressure have a positive impact. However, the elderly must exercise due diligence, the body can be slightly sweating. Exercise brain as soon as possible, any age is not late. A recent study published in the British Journal of Sports Medicine found that keeping 45 minutes of sustained activity a week could improve the mental performance of more than 50-year-olds.


Eat more anti-oxidant foods. Geng Tongchao pointed out that the delay in brain aging can be more intake of flavonoids or carotene-rich antioxidant, anti-aging foods, such as moderate drinking more tea, eat more fruits, vegetables, nuts, can effectively delay brain aging. Many elderly people do not eat meat and egg yolk in order to prevent and cure diseases. This is not true. Meat contains cholesterol, which favors the formation of myelin sheaths in nerve cells. There are many choline in egg yolk, which helps to supplement nutrition needed by the brain.


Feel sleepy. Many people found that the spirit and physical strength decreased the next day after staying up late. Geng Tong Chao said that everyone should ensure adequate sleep. "Sleeping enough for 7 hours" argument does not necessarily apply to all people, usually teenagers sleep enough 7 to 9 hours, pregnant women guarantee 8 to 9 hours, children sleep 10 to 12 hours a day. Sleep time can be judged according to their specific circumstances, as long as wake up after a lack of feeling, physical comfort, it is effective sleep.


Stay optimistic. Zhang Zhenxin said, a happy mood will affect the body's hormone levels, metabolic levels become higher, the brain blood supply, adequate oxygen. Sometimes we need to develop reverse thinking, optimistic about things. Such as wrestling fractures , do not think about how unlucky, but think just a fracture, and did not lose precious life.


Brain health is inseparable from the general health, so to develop a healthy lifestyle and pay attention to the development of this good habit is particularly important.
