The treatment of Alzheimer's disease mainly includes the following aspects. First, enhance care to prevent accidents. Patients with Alzheimer's may get lost, forget to turn off fires or gas, etc., so it is essential to strengthen care to prevent accidents. Second, encourage the elderly to read more books and newspapers and enhance learning, which can effectively slow down the progression. Third, have the elderly interact more with others and exercise more. This can strengthen their physical health and, to some extent, delay the development of Alzheimer's disease. Another aspect is drug treatment, which mainly includes acetylcholinesterase inhibitors and some NMDA receptor antagonists. These can improve the symptoms to some extent and enhance the quality of life. Additionally, in the later stages of Alzheimer's, some psychiatric symptoms such as visual hallucinations and aggressive behavior like hitting or yelling may occur. Appropriate atypical antipsychotic drugs can be administered for treatment.
