Clinical trials

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
