Why do some people get Alzheimer's disease?

The so-called Alzheimer's disease refers to a persistent disorder of higher nervous function, that is, the disorder of memory, thinking, analysis and judgment, visuospatial recognition, emotion and so on without conscious disturbance. With the development of modern medicine, more and more elderly people become young and full of vitality. But please don't forget: in the near future, China will enter an aging society. At the same time, it is accompanied by a problem that cannot be ignored-the incidence of Alzheimer's disease is increasing year by year. The survey found that the average age of Alzheimer's disease in northern China is 75 and 76 years old, and the age of vascular dementia is about 68 years old. The rate of severe Alzheimer's disease among people over 65 years old is above 5%, and by the age of 8, the rate will rise to 15-2%. The ability of daily living of Alzheimer's patients is declining. They don't know their spouses and children, and they can't take care of themselves in dressing, eating and urinating. Some also have auditory hallucinations, which bring endless pain and trouble to themselves and the people around them. The average survival time of patients with Alzheimer's disease is 5.5 years. After cardiovascular disease, cerebrovascular disease and cancer, Alzheimer's disease has become the "fourth killer" of the health of the elderly. Dementia is no longer a "patent" for the elderly, and the number of people with dementia in their forties and fifties is increasing year by year. Not only the elderly, the 5-year-old daughter accompanied the 8-year-old mother to see a doctor, and both of them were diagnosed with Alzheimer's disease; The 47-year-old woman's forgetfulness is also caused by Alzheimer's disease ... All these show that the age of suffering from Alzheimer's disease is ahead of schedule. Alzheimer's disease is gradually becoming younger, and vascular factors are playing an increasingly prominent role in the pathogenesis. In fact, Alzheimer's disease begins to have symptoms and reactions in middle age. If it is not found and treated early, it will not be cured if it develops seriously. Dementia is no longer a "patent" for the elderly. Experts say that early dementia can be cured, but it can't be treated until the age of 6 or 7. The first symptom begins with amnesia. Although the cause of the most common senile dementia has not been found, all dementia has signs to follow, and the first sign is amnesia. Middle-aged, let's see if you are particularly forgetful recently. If you only forget it occasionally, but you can remember it slowly afterwards, this is normal. However, if you often forget things, and some things are deliberately forgotten, you can't remember them afterwards, and even affect your work and life. It is best to go to the hospital for a check-up. With "amnesia", there are some obvious signs. You might as well give yourself the following self-test. Once you feel wrong, don't be careless, or be afraid of others' jokes. Early symptoms can be cured. Don't wait until the diagnosis is made. Generally speaking, Alzheimer's disease often occurs after the age of 5, with latent onset and slow development. At the earliest stage, it often begins with gradual forgetfulness. If you don't pay attention, it is usually not easy to find it. According to the development of the disease, it can be roughly divided into three stages: the first stage, also known as forgetfulness, is characterized by obvious memory loss, such as forgetting what you said, did or made important appointments at the beginning, and slowly forgetting even distant things. At the same time, thinking analysis, judgment ability, visual space discrimination function, calculation ability, etc. have also decreased, but sometimes they can maintain their familiar jobs or skills. The second stage, also known as the chaotic stage, is characterized by the obvious aggravation of visual space recognition disorder and easy to get lost, in addition to the aggravation of symptoms in the first stage. It is also difficult to dress, or wear pants as clothes; I don't know the faces of friends or relatives, I can't remember their names, and I can't talk to others, although I sometimes talk to myself. In the third stage, patients with extreme dementia enter a state of total decline, and they can't take care of themselves. For example, eating, dressing and bathing need people to take care of them, so they are incontinent. Ten warning signs of Alzheimer's disease 1. Memory is declining. Affect daily activities. 2. Difficulties in dealing with familiar things. 3. Increasingly confused about time, place and people. 4. Declining judgment. 5. Often putting things in inappropriate places. 6. Problems with abstract thoughts. 7. Unstable emotional performance and abnormal behavior. 8. Changing personality. 1. Losing the initiative to do things. It is difficult to understand the ability of things and language expression. The prevention of Alzheimer's disease is different because of the different causes of dementia, mainly in the following aspects: 1. Improve the working environment. 2, avoid alcohol and quit smoking. 3. Diet regulation: It is necessary to prevent high-fat foods from raising cholesterol, and to take in necessary nutrients, such as protein, inorganic salts, amino acids and various vitamins, especially vitamins B1, B2 and B6, vitamin C and vitamin E, which are very important for the elderly. 4. Being cheerful is good for longevity and mental health. 5, to arrange life and study: in old age, we must persist in learning new knowledge and maintain extensive contact with society. 6. Before retiring, we should make all preparations ideologically and materially. Rich life content and extensive interests and hobbies can promote mental activities and delay or alleviate the process of aging. 7, regular physical examination, early treatment of physical diseases, not only pay attention to their own bodies, but also do not pay too much attention or worry. 8. Regular outdoor activities: The elderly are suitable for more sustained and competitive sports, such as walking, jogging, gymnastics, Tai Ji Chuan, Taijiquan and traditional dance.
