Alzheimer’s disease can be treated with medication to a certain extent, which can ease the progression of the disease. The specific treatment effect is related to the severity of the disease, drug absorption and other factors, can not be generalized. 1. Severity of the disease: At present, there is no specific drug for Alzheimer’s disease in the clinic, and the drugs include donepezil, memantine, cytarabine and so on, which can alleviate the patient’s condition. If the condition is mild, the symptoms can be controlled significantly after using drugs; if the condition is serious, the control effect of drugs may be poor. 2. Drug absorption: the effect of Alzheimer’s medication is related to the patient’s body absorption ability. Part of the patient’s body absorption, metabolism ability is good, oral drug absorption is fast, the therapeutic effect is relatively obvious. The other part of the patient’s absorption is slow, the therapeutic effect is relatively poor. In order to achieve the ideal therapeutic effect, it is recommended that patients do regular checkups and re-examinations, and adjust the dosage of medication in a timely manner under the guidance of the doctor to control the condition according to the patient’s mental and behavioral symptoms.
