Patients with Alzheimer’s disease often present with mental and behavioral abnormalities, with insomnia, delirium, and delusions of victimization predominating among their symptoms, cognitive impairment, mainly memory impairment, especially early near-memory impairment, disorientation, and character orientation disorder. Therefore, experts believe that the care of Alzheimer’s patients should be strengthened to slow down the progress of the disease. 1, Alzheimer’s patients are unresponsive, sometimes even if they have symptoms, they do not say it in time, so it is necessary to observe whether the patient has red and feverish face and painful facial expressions, and if abnormalities are found, seek medical attention in time to avoid aggravation and life-threatening conditions. 2, we should pay attention to the contraindications of Alzheimer’s patients, do not give the elderly alcohol, smoking, drinking strong tea, coffee, so as not to affect the quality of sleep. 3, in the care of dementia patients should pay attention to the safety of patients, some dangerous items should be closely guarded, reduce the placement of indoor objects and appliances, the bed should be low, soft and comfortable, if necessary, the use of restraint belts to prevent falling out of bed and fall. 4.Living daily care. Diet should be light, nutritious, easy to digest, if you eat fish and shrimp, should be taken out on behalf of the fish spines, shrimp shells peeled off, so as not to choke on fish spines. According to the temperature change, we should also increase or decrease the clothes for the elderly. 5, Alzheimer’s patients suffer from memory impairment, so when the elderly go out, they should prepare a card, write down the address, and should also write down the contact information, so that the patient does not know the way, take the wrong route, but also convenient to contact with family members in time. The above is the introduction of “Alzheimer’s disease care”, I hope that patients and family members do a good job in the care of Alzheimer’s patients, to actively cooperate and ensure the implementation of the various treatment measures to help patients recover as soon as possible, get rid of Alzheimer’s disease troubles.
