It is common for many old people to lose their memory with age, and they often forget it one way or another. So how can the elderly enhance their memory? Let's take a look! Clark, a psychologist at the Loman Institute in Toronto, Canada, put forward through experiments: "In healthy people, the speed of memory degradation is not as fast as most people think. People's memory mechanism will not be damaged with age. It's just that the efficiency is reduced. " Shakespeare, an English dramatist, famously said, "Although I am in my twilight years, I still have some memories; The oil lamp I hung is still shining with the last glimmer. "Middle-aged and elderly people may easily remember everything that happened last night or this morning. If you ask them what they experienced ten days ago, they may not remember clearly. However, the interesting stories encountered in childhood or the terrorist events experienced in the past may be unforgettable for life, so that the old stories after several years are still fresh in my memory. Some people mistakenly think that important things are easier to remember than unimportant things. In fact, the memory biology, a new discipline formed in recent years, lists a large number of examples, which shows that the memory storage decision of the human brain depends on the human physiological system. Old people usually think that their memory is far inferior to that of young people. Mrs. Ruth Arnold, an American scholar, once worked in the reference room of the library of California Medical College. Many years ago, she could point out the details of a chapter in a reference book at will from memory. At that time, she could recite the titles of all the reference books in the room and tell the main contents of the books. Mrs Arnold is 84 years old. She felt that her memory was failing. She often can't remember the appointed time, and sometimes she forgets who she is going to visit or who she is going to talk to. Old people are used to the memory being less painful than before. It is not surprising that people think that all this is a reflection of aging. According to the survey, about one-third of the elderly remember the names and things they come into contact with in their lives as well as the 20-year-old people, which means that memory decline is not inevitable. Scientists in many memory research centers in the United States are looking for the potential causes of memory loss and non-Alzheimer's disease, with the aim of finding a treatment to enhance the memory ability of the elderly by controlling the concentration of neurotransmitters. At present, several endocrine hormones, such as adrenaline, adrenocorticotropic hormone or vasopressin, have the function of regulating memory. Adrenal gland is the most important hormone for memory, because adrenaline is a hormone that is very sensitive to stress and environmental changes. For example, after the earthquake, people are afraid to live in tall buildings. Dr Small of Columbia University used a magnetic vibration system to explore how Alzheimer's disease and age-related memory loss attack people's brains. The research results have confirmed that this is the result of nerve connection disorder, not the real nerve cell death. In a large number of patients with brain atrophy, the number of brain cells remains relatively unchanged, and there is a lack of decisive neurotransmitters, which leads to nerve endings. After injecting dopamine substitutes, the memory was obviously enhanced. Of course, it will take about 5~ 10 years to treat all memory diseases and improve the memory decline of the elderly. Speed reading memory experts remind: "Method is the mother of memory". So, how to enhance memory? Experts all over the world have put forward some methods: the centralized method is to focus on what you want to remember and then give it meaning. If we have focused on something, we will remember it whether we want to remember it or not. For example, it is easy for us to remember advertising songs. Advertising songs are always accompanied by noisy and flashy advertisements, and rhymes and music are used to help us remember. Simply sorting out boring things helps to remember; Another example is the chaotic manifest, which can be classified to minimize the number of items to be recorded. Memory training is to encode names, faces and events. According to a certain mode of thinking. Usually a "forget-me-not area" will be set up; Write a "to-do list"; Leave the bill near the gate and wait. Robert Butler, president of the American International Longevity Center, said: "You can play charades, read more books and debate more, which will help to enhance your memory. "Fitness and brain strengthening can keep your mind strong by using more brains. The French call it "brain jogging". Think more and exercise your brain. Because fitness helps to strengthen the brain. Doing aerobic exercise can send more blood to the brain, bring in more oxygen and glucose, and enhance brain function. Margaret Sewell, director of the memory enhancement program at Mount Sinai Medical Center in new york, said: "Keeping your brain strong and exercising regularly can avoid memory loss. Poor health or illness often leads to memory loss.
