Electro-acupuncture for SCD With Depression

The goal of this clinical trial is to evaluate the efficacy and safety of electroacupuncture in treating adults with subjective cognitive decline accompanied by depression. The main objectives are to answer the following questions: 1. Can electroacupuncture improve cognitive function and depressive symptoms in individuals with subjective cognitive decline accompanied by depression? 2. Does electroacupuncture alleviate subjective cognitive decline with depression by modulating the amygdala-entorhinal circuit, and if so, what is the specific mechanism involved? Researchers will compare real electroacupuncture therapy with sham electroacupuncture therapy to determine whether real electroacupuncture can effectively improve symptoms in patients with subjective cognitive decline accompanied by depression. Additionally, multimodal magnetic resonance imaging (MRI) technology will be used to assess changes in the amygdala-entorhinal circuit following electroacupuncture intervention. Participants will: 1. Receive either real or sham electroacupuncture treatment once daily, 3-5 times per week, for a total treatment duration of 8 weeks. 2. Undergo cognitive function and depression assessments before and after treatment. 3. Complete multimodal cranial magnetic resonance imaging examinations before and after treatment.
