Alzheimer’s disease is a chronic disease that does not cause death and does not affect life expectancy. Patients die because they do not pay attention to the later stages of care, leading to secondary lesions and other fatalities. The course of the disease is about 5-10 years, but a few patients can survive for more than 10 years, and the exact length of life varies from person to person. Alzheimer’s disease, also known as Alzheimer’s disease, is a common first symptom of memory loss. As the disease progresses, the patient loses reasoning, language, decision-making, judgment and other key skills, making it impossible to carry out daily life without the help of others. Sometimes patients also experience personality as well as behavioral changes. The disease is not curable and medication is of limited effectiveness. Therefore, the main focus of care for these patients is nursing. Effective care can prolong the patient’s life and improve his or her quality of life. Some patients eventually die from complications such as lung infections, urinary tract infections, and pressure sores, and usually survive for about 5-10 years. Therefore, the patient’s family needs to focus on nursing care to prolong the patient’s life as long as possible.
