Alzheimer’s disease (AD) is a progressive neurodegenerative disease with an insidious onset and progressive development. It is characterized by a full spectrum of dementia, including memory impairment, aphasia, dysfunction, loss of recognition, impairment of visuospatial skills, executive dysfunction, and personality and behavioral changes, the cause of which is still unknown. So, how to prevent the occurrence of Alzheimer’s disease? The following are the main measures to prevent the occurrence of dementia: 1. Drug prevention: Chinese medicine believes that the essence of aging in the elderly is Yang deficiency and blood stasis. The spleen and kidneys are the mainstay of medicine, and elderly people with Yang deficiency can often take products that strengthen the spleen and kidneys to prevent aging. Effectively controlling the development of cerebral arteriosclerosis is of positive significance in improving the blood perfusion of brain tissue and maintaining normal brain metabolism, which can prevent the occurrence of dementia. Evening primrose, zelen, zedoary, atractylodes, astragalus, geranium, and chuanxiong are used to identify the evidence. You can also use 4 capsules of evening primrose oil (3 times a day), 3 tablets of compound Dan Shen (3 times a day), 10g of Atractylodes Macrocephalae (2 times a day), 5 tablets of blood circulation (3 times a day) and 3 tablets of Guaifeng Ningxin (3 times a day) to take one of them. 2, moxibustion prevention: moxibustion can help Yang and eliminate stasis, prolong life, moxibustion of the Ren vein Shen Que, Qi Hai, Guan Yuan, the Governor’s Life Gate, the Great Vertebrae, the Plastered Heart, Kidney Yu, Zhi Chamber, the stomach meridian of the foot San Li points (double), each time moxibustion five strong, all have the effect of tonifying the kidneys and filling essence to help Yang, prevent aging and prevent dementia. 3, to avoid the occurrence of cerebral arteriosclerosis and cerebral thrombosis and other diseases: to prevent dementia caused by insufficient blood supply to the brain. Adjusting the diet, eating less salt, and carrying out suitable physical activities can help prevent arteriosclerosis. 4, pay attention to intellectual training: diligent use of the brain to slow down brain aging. Some research shows that often do brain and interesting things, can keep the mind sharp, forging brain cells responsive. Older people should stay active and use their brains more, such as reading more books, learning new things and cultivating a variety of hobbies, which can activate brain cells and prevent brain aging. Extensive contact with people from all walks of life is beneficial to maintaining brain power. Talking with friends, playing mahjong, chess, etc., can stimulate brain power and stimulate the vitality of nerve cells. 5, mental conditioning: pay attention to maintain optimism, should be section of the thought, to worry, prevent panic. Tranquility and fearlessness, tranquility and emptiness, and the world does not compete, contentedness and happiness, clear-mindedness. In this way the blood and qi harmonization, health does not decline. Pay attention to maintaining interpersonal relationships to avoid long-term melancholy and depression, which is also a risk factor for dementia in the elderly. Avoid mental stimulation to prevent damage to brain tissue function. In addition, maintaining family harmony can keep the mood happy and can enhance the ability to resist disease. 6, physical exercise: exercise can also promote the production of nerve growth hormone and prevent brain degeneration. Proper physical exercise is good for health, such as insisting on walking, playing tai chi, doing health exercises or practicing qigong, etc., which is conducive to the lifting of brain inhibition and improve the activity level of the central nervous system. However, it is necessary to proceed step by step, according to the ability and persistence to achieve the desired effect. In addition to the overall body activities, try to move your fingers more. 7, living and eating: living and eating should be regular, not change irregularly. Generally should go to bed early and get up early, eat regularly and defecate regularly. Pay attention to keep the bowel movement smoothly to prevent the occurrence of dementia also has positive significance. In terms of diet, the following points should be noted: (1) Emphasize the “three fixed, three high, three low and two quit”, i.e., regular, quantitative and qualitative, high protein, high unsaturated fatty acid and vitamin, low fat, low calorie and low salt, and quit smoking and alcohol. (2) Avoid using aluminum drinking utensils. Once salt enters the body, it is first deposited in the brain and induces Alzheimer’s disease. (3) Supplementation of beneficial minerals and trace elements, lack of essential trace elements (such as zinc, etc.) can lead to insufficient blood supply to the brain, causing vascular lesions and leading to dementia. It can also be appropriately supplemented with: (4) Vitamin E: Although there is no study that clearly shows that vitamin E can increase memory, vitamin E is an antioxidant that can stop nerve cells from being damaged by free radicals. Meanwhile, a study pointed out that Alzheimer’s patients who took vitamin E for two years in a row delayed the degeneration for 8 months. Experts suggest that a daily supplement of 400 units of vitamin E can help prevent Alzheimer’s disease. (5) Female hormones: Recent studies have shown that women who take female hormone supplements after menopause can reduce the chance of developing Alzheimer’s disease by 30 to 40%. (6) Eat more fish: A large-scale study in the Netherlands showed that if you eat more fish and have lower cholesterol in your diet, your chances of getting Alzheimer’s disease are only 0.4 times higher than the average person. The study was conducted on 5,000 people over the age of 55.
