The goal of this clinical trial is to learn if silkworm pupa powder works to treat Alzheimer's disease in patients. It will also learn about the safety of silkworm pupa powder, and its effect on patients' nutritional and frailty status. The main questions it aims to answer are: * Does silkworm pupa powder improve cognitive function and daily living abilities? * Does silkworm pupa powder improve nutritional status and frailty? * What medical problems do participants have when taking silkworm pupa powder? Researchers will evaluate the treatment by comparing the participants' conditions after taking the powder to their baseline conditions (a single-arm study without a placebo) to see if silkworm pupa powder works to treat Alzheimer's disease. Participants will: * Take silkworm pupa powder every day for 12 weeks * Visit the clinic once every 4 weeks for checkups and tests * Use an electronic punch-card system daily and report any symptoms

The purpose of this clinical trial is to determine whether silkworm pupa powder is effective in treating Alzheimer's disease. It will also investigate whether silkworm pupa powder can improve the nutritional and frailty status of patients with Dementia. The main questions it aims to answer are: * Will silkworm pupa powder improve the daily living conditions of patients with Alzheimer's disease? * Will silkworm pupa powder improve the nutritional status and frailty of Alzheimer's disease patients? Researchers will compare silkworm pupa powder with a placebo (a similar substance containing 0.5% silkworm pupa powder) to see if silkworm pupa powder can treat Alzheimer's disease. Participants will: * Take silkworm pupa powder or placebo daily for four months; * Visit the clinic for check-ups and tests every four weeks; * Record their symptoms and various physiological indicators.

The goal of this clinical trial is to learn if silkworm pupa powder works to improve the nutritional status of Alzheimer's disease patients. The main questions it aims to answer are: * Does silkworm pupa powder evaluate the effectiveness of silkworm pupae in improving sarcopenia, frailty and quality of life in AD patients? * Does silkworm pupa powder improve cognitive function in AD patients? Researchers will compare silkworm pupa powder to a placebo (a look-alike substance that contains no drug) to see if silkworm pupa powder works to improve the nutritional status of Alzheimer's disease patients. Participants will: * Take drug silkworm pupa powder or a placebo every day for 3 months. * Visit the clinic once every 4 weeks for checkups and tests. * Keep a diary of their daily consumption.
