Alzheimer’s patients are treated and cared for either at home or in hospitals and old age homes. So, what kind of care is scientific? 1, first of all, to prevent the elderly bedridden patients with Alzheimer’s disease, family members are often prone to overprotection tendency, which is the biggest cause of bedridden patients. Once the patient is bedridden, there can be many complications, which will aggravate the symptoms of dementia, accelerate the shortening of its life, so the early dementia patients should let them under the care and guidance of family members to do some things within their capabilities. In addition, family members should also understand the patient’s psychological state, should never alienate the patient, to help the patient to eliminate psychological barriers and behavioral disorders, to help the patient to restore memory. This is a very important part of the prevention and treatment of early-stage patients. 2, pay attention to diet and nutrition Alzheimer’s patients generally have different degrees of eating disorders and swallowing disorders. In addition, the elderly themselves have low renal function, low digestion and absorption function, reduced basal metabolism and reduced physical activity, etc., which makes the utilization and absorption of nutrients in the body prone to obstacles, leading to malnutrition and even anemia. Therefore, the diet of dementia patients should take into account the balance between quantity and quality, and use foods that are easy to digest and swallow, and do not need to limit the intake of protein and fat. Low nutritional status will further promote the development of the disease. 3, to maintain daily hygiene habits of early dementia patients should be as far as possible to help them maintain their daily living habits and hygiene habits. Getting up, dressing, brushing teeth, washing face, etc., even if it is not done in a standardized way, we should let him do it by himself as much as possible. Because this is also a part of the prevention of further development of the disease can not be ignored. For bedridden patients, care must be given to clean the mouth, to bathe and wash the patient’s hair at regular intervals, and to change clothes. Incontinence occurs from time to time in patients with dementia, once incontinence occurs, that is, the disease has reached a fairly serious period. However, defecation and urination should be handled in a timely manner, cleaned, and the skin kept clean and dry to prevent infection. 4, to prevent infection The incidence of pneumonia in dementia patients is very high, and the mortality rate is also very high. According to foreign survey data reports, the cause of death of dementia patients more than ninety percent is due to complications of pneumonia and death. Once complicated, the course of the disease progresses rapidly, especially in bedridden patients, the decline of body functions, such as the decline of respiratory system functions, the decline of the body’s ability to defend against infections, as well as consciousness disorders, malnutrition, incontinence, decubitus ulcers, which is very easy to be complicated by pneumonia. Therefore, we should avoid the occurrence of the above situations as much as possible, and once the complication of infection should be treated promptly. 5, to prevent bedsores The so-called bedsores are necrosis of the skin and subcutaneous tissue due to local circulatory disorders. To prevent the occurrence of bedsores, first of all, we should carry out systemic and local management for bedridden patients. Systemic management includes treatment of the primary disease, improvement of the general condition, maintenance of the water-electrolyte balance, and prevention of infection. Local management: change the position of bedridden patients once every 2-3 hours, pay attention to the skin, keep the skin clean, can’t use alcohol, purgative cleaning, wash with warm water is better. Localization can use cotton pads, pillows, foam cushions pillow on the buttocks, ribs and other hairy parts.
