Early treatment of Alzheimer’s disease involves removing and improving factors that may aggravate Alzheimer’s disease, such as cerebral ischemia, vitamin deficiencies, smoking, and lack of exercise, on the one hand, and medications such as donepezil, on the other. The onset of Alzheimer’s disease is associated with many triggers, and removing these risk factors can slow down the progression of Alzheimer’s disease. For example: correcting possible insufficient cerebral blood supply and narrowing of cerebral arteries; giving aggressive supplementation to patients who are deficient in vitamin B or certain trace elements; quitting smoking, drinking, and increasing time spent on aerobic exercise; and avoiding long-term use of medications that may affect cognitive function. In the early stages of Alzheimer’s disease, when the condition is mild, taking drugs such as donepezil and strychnine A is also a common treatment. In addition, for patients in the early stages of Alzheimer’s disease, encouraging them to interact more with people, socialize appropriately, and read more books, newspapers, and cards are also important treatments.
