About

The aim of this clinical trial is to determine whether Lymphaticovenous Anastomosis can treat Alzheimer's disease，in AD patients aged 18-80.he main questions it aims to answer are:

1. Can Lymphaticovenous Anastomosis improve cognitive function, daily living ability, mood, or sleep status in patients with Alzheimer's dementia, demonstrating good therapeutic efficacy?
2. Does deep Lymphaticovenous Anastomosis lead to changes in peripheral blood biomarker levels, neuroinflammatory responses, and neuroimaging in patients with Alzheimer's dementia?

Enrollment: 20 estimated patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers
