In the late stage of Alzheimer’s disease, there are two general types of refusal to eat, i.e., the patient is reluctant to eat or refuses to eat because of swallowing disorder and organic discomfort while swallowing something. If it is because of the first kind of reluctance to eat, the person who is close to the patient is required to have enough patience with the patient and needs to be coaxed or induced like a small child. This is because if the patient does not eat for a long time, gastrointestinal dysfunction will occur and pathological changes will occur later, thus making it impossible to reverse the patient’s eating function. If the patient has developed swallowing disorders, such as choking and coughing when drinking or eating, it is important to consider that the patient’s disorder may have entered the middle and advanced stages and consider giving the patient a gastric tube nasal feeding. In the beginning, family members can also try to make the food into puree or liquid viscous food, which is good for the patient to swallow and not easy to cause choking and coughing. The patient can often be coaxed to eat on this basis. The last resort is to administer a nasal feeding of a liquid diet through a gastric tube to ensure the patient’s water and electrolyte balance and nutritional supply.
