Six characteristics of brain aging
1. Decreased visual spatial ability. People's recognition and spatial positioning of objects in the three-dimensional world belong to the visual space ability. The decline of visual space ability can cause people to have obstacles in direction judgment, such as getting lost, unable to distinguish the direction, not knowing which building and unit of their home is; when taking a car, they will take one more stop or one less stop. 2. Decreased language ability. Language skills mainly include listening, speaking, reading, writing, naming and paraphrasing abilities. When language ability declines, people not only become unresponsive, but they also experience deviations in understanding or barriers in expression. Sometimes, they only use the language they remember. For example, the elderly may suddenly not remember what the elevator says, and can only be described as "something that can go up and down." Or when others talk about taking an elevator, the elderly cannot understand what an elevator is. Once the decline in language ability has an impact on life, it is necessary to go to the hospital for examination in time. 3. Ability to control emotions. Under normal circumstances, people can better control their emotions. When the emotional control ability is hindered, it will show indifference, loss of interest in other things, irritability, and emotional instability. 4. Decline in execution ability. Including the ability of planning, organization, decision-making and execution, and can simplify the environment and improve work efficiency. When the execution ability declines, it is often impossible to complete multiple tasks. You can only do one thing one at a time, or even one thing cannot be done well. 5. Decreased concentration. It is not too difficult to concentrate at work, but as people get older, some people will have difficulty concentrating. For example, when others are talking, they become unconsciously distracted. This is a manifestation of decreased concentration. 6. Poor memory. Deteriorating memory is the mantra of many people, and this is also the most obvious and easiest manifestation of dementia. If you keep repeating an action or saying the same sentence, you always think that you are going to wash the dishes after eating. The performance of these memory loss may affect people's normal life. Five factors of brain aging 1. Diabetes: Diabetes can harden and occlude brain capillaries and increase blood viscosity. The brain is in a state of ischemia and hypoxia for a long time and ages faster than ordinary people. Hypertension, atherosclerosis, etc. can also accelerate brain aging. 2. Smoking: When smoking, the nicotine in cigarettes can reach the brain within 10 seconds of inhalation, and remain active within 20-40 minutes. Nicotine can damage blood vessel walls, promote arteriosclerosis, reduce brain oxygen supply, impair logical thinking, and accelerate The brain is aging. A study in the United States showed that smoking a pack of cigarettes reduces life by 2.3 hours. 3. Air pollution: The brain is the organ that consumes the most oxygen in the whole body, consuming 500 to 600 liters of oxygen per minute on average. There is not enough oxygen in the polluted air to support the work of the brain. It also contains harmful substances such as nitrogen oxides and carbon monoxide, which enter the brain through breathing, causing memory decline or depression, and accelerating the cognitive decline of adults. 4. Overeating: After overeating, the human body tends to mobilize a large amount of blood and energy to the digestive system in order to digest too much food. The energy supply of the brain is reduced, and the brain is in an ischemic state, which will damage the brain cells. 5. Habits to stay up late: Irregular life affects the body's normal biological clock and metabolism, and brain function is disrupted. Staying up late will make the brain in a state of excitement, and the delay in getting a rest makes the brain not fully repaired and damages the brain's neuronal cells. British research found that irregular rest and frequent night shifts can impair the cognitive ability of the brain.
