This year, September 21 is the 22nd World Alzheimer’s Day. Alzheimer’s disease is also known as Alzheimer’s disease. It is estimated that there are about 8 to 10 million people with Alzheimer’s disease in China. With increasing aging, it is expected that there will be 30 million such patients in China by 2050. At present, Alzheimer’s disease is gradually becoming younger in China, and many middle-aged people in their fifties are already showing symptoms of Alzheimer’s disease, such as a significant decline in memory and thinking ability, especially in the impression of professors and senior workers. Is it true that Alzheimer’s disease prefers people with high IQs? According to Dr. Yin, deputy director of the Department of Neurology at Long March Hospital of the Second Military Medical University, this is a misinterpretation. The reason why people think that people with high IQ are more prone to Alzheimer’s disease is related to their higher profile. In addition, people with high IQ are often engaged in brain work, but insomnia and anxiety caused by excessive brain overdraft when they are young can also increase the risk of developing Alzheimer’s later. 1, less than 6 hours of sleep per night, later or Alzheimer’s dementia Today, sleeping late is common among young people, and staying up late also seems to be a matter of habit. They often realize that it’s time to go to bed, but they just “can’t” sleep, and then brush the circle of friends, play games, browse the microblogging, always two or three o’clock in the middle of the night before they love to go to sleep. Although the next day when you get up, you feel remorseful for staying up late yesterday, but the night will still stay up to the end. Yin also pointed out in this regard, long-term sleep deprivation can cause the accumulation of harmful substances in the body. “Generally speaking, less than 7 hours of sleep, the brain will begin to release harmful substances. When less than 6 hours of sleep, harmful substances will increase exponentially. In the long run, this will lay a hidden danger for the future development of Alzheimer’s.” Many office workers usually choose to pay off their “sleep debt” on weekends because they are busy at work, is this useful? Yin also said that even with a few nights of adequate sleep to restore strength, the harmful effects of staying up late still exist. “Many people feel more tired and uninterested in everything after a weekend of sleep, which is actually beyond their personal tolerance limit.” Yin also suggested that late sleep, stay up late should be measured, once found that the impact of staying up late beyond the limits of personal tolerance, should change the routine. 2, family care can slow down the process of Alzheimer’s disease According to the data from the memory disorder clinic of the Changzheng Hospital of the Second Military Medical University, the rate of Alzheimer’s disease visits has increased 2-3 times in recent years with the growing concern of society for Alzheimer’s disease. However, there are still some misconceptions about the home care of patients. Some people express their inability to understand the clinical symptoms of Alzheimer’s disease and neglect to care for and understand the elderly. Among the patient’s family members, there is often a misconception that keeping the elderly well-fed and well-drunk is all that is needed. However, Yin also emphasized that the care and companionship of loved ones is the best medicine to prevent and treat dementia. He explained that retired or widowed people have a high risk of developing Alzheimer’s disease due to chronic depression, social inactivity and lack of physical and mental activity. Those who do not live with their children also deteriorate more quickly when they become ill due to a lack of emotional support. Therefore, Yin also recommends that seniors should live with their families as much as possible. Caring for the elderly with dementia can be a long and tiring battle for family members, and some physically and mentally exhausted family members suffer from anxiety and depression as a result of caring for the elderly with dementia. Yin also said that for family members, the first thing is to take care of themselves, to ensure good sleep, and pay more attention to the spiritual and material life of the elderly, more hobbies, or often go out with the elderly, which is also a kind of relief after the depression. In the early stage of the disease, family members need to strictly instruct the elderly to take medication on time, which can help to slow down the disease process. 3, determine the tendency of Alzheimer’s, draw a clock to try It is understood that the symptoms of Alzheimer’s disease is not obvious at first, usually to forgetfulness, mood and personality changes, with increasing age symptoms significantly aggravated. But people around the old man’s strange, abnormal behavior mistaken for the old man’s old age, brain, etc., did not pay enough attention to delay the disease. How can we detect the tendency of Alzheimer’s disease in the family in time? Yin also introduced, test whether the elderly dementia, the international common “drawing clock” method, that is, require the subject to independently draw a clock on white paper, and mark the specified time, for example, 9:10. Specific scoring: (1) draw a closed circle, 1 point; (2) will be placed in the correct position of the dial, 1 point; (3) in order to fill in the 12 numbers on the dial correctly, 1 point; (4) will be placed in the correct position of the hands (whether there are arrows on the hands, whether the minute hand is longer than the hour hand, etc.), 1 point. A score of 4 on the clock drawing test is normal, 3 is basic normal or mild dementia, 2 is mostly moderate dementia, and below 2 is already to severe dementia. Yin also explained that the memory loss that occurs in Alzheimer’s disease is somewhat different from the general forgetfulness of the elderly. The early stage of Alzheimer’s disease is mostly accompanied by the decrement of spatial structure function and executive function, so the clock drawing test can determine whether the spatial structure function and executive function of the elderly are decremented, which is highly accurate and effective in detecting the tendency of Alzheimer’s disease in time.
