NCT07350226

Brief Summary

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. 1.Can electroacupuncture improve cognitive function and depressive symptoms in individuals with subjective cognitive decline accompanied by depression?
  2. 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.
  3. 3.Receive either real or sham electroacupuncture treatment once daily, 3-5 times per week, for a total treatment duration of 8 weeks.
  4. 4.Undergo cognitive function and depression assessments before and after treatment.
  5. 5.Complete multimodal cranial magnetic resonance imaging examinations before and after treatment.

Outcome Measures

Primary Outcomes (3)

  • Comprehensive Cognitive Z-Score

    This composite index of global cognitive function is derived from the aggregated Z-scores of eight neuropsychological tests (including Auditory Verbal Learning Test, Animal Fluency Test, Boston Naming Test, Trail Making Test Parts A/B, Stroop Color-Word Test-Card C, Digit Symbol Substitution Test, Digit Span Test, and Clock Drawing Test). At baseline, each test's raw scores will be standardized using the study population's mean and standard deviation (Z = \[raw score - mean\]/SD). For tests where lower scores indicate better performance (e.g., Trail Making Test time), Z-scores are reversed (multiplied by -1) to align directionality. The final aggregated Z-score, expressed in standard deviation units, will be assessed pre-treatment and 8 weeks post-treatment initiation.

    Before and 8 weeks after treatment

  • Geriatric Depression Scale 15-Item (GDS-15) Reduction Rate

    The reduction rate is calculated based on the total score (range: 0-15, where a higher score indicates more severe depressive symptoms) of the 15-item Geriatric Depression Scale. The reduction rate formula is: (\[Pre-treatment score - Post-treatment score\] / Pre-treatment score) × 100%. Efficacy is defined as: Markedly Effective (reduction rate ≥ 50%); Effective (50% \> reduction rate ≥ 25%); Ineffective (reduction rate \< 25%).

    Before and 8 weeks after treatment

  • Multimodal magnetic resonance imaging indicators

    sMRI indicators: GMV, FA, MD; rs-fMRI indicators: ALFF, fALFF, ReHo, Seed-based FC.

    Before and 8 weeks after treatment

Secondary Outcomes (12)

  • Mini-Mental State Examination (MMSE) Total Score

    Before and 8 weeks after treatment

  • Auditory Verbal Learning Test (AVLT) Long-Delay Free Recall Score

    Before and 8 weeks after treatment

  • Rey-Osterrieth Complex Figure Test (ROCF) Delayed Recall Score

    Before and 8 weeks after treatment

  • Boston Naming Test (BNT) Total Correct Score

    Before and 8 weeks after treatment

  • Animal Fluency Test (AFT) Total Score

    Before and 8 weeks after treatment

  • +7 more secondary outcomes

Other Outcomes (2)

  • Treatment Acceptance Survey Response

    After 8 weeks of treatment

  • Incidence of Treatment-Emergent Adverse Events (TEAEs)

    From treatment initiation up to 8 weeks.

Experiment group

EXPERIMENTAL

"TXJN" electro-acupuncture:Disposable acupuncture needles (Huatuo brand, Suzhou Medical Supplies Factory Co., Ltd., specification: 0.25 mm × 40 mm) were used.The selected acupoints included bilateral Neiguan (PC6), Yintang (EX-HN3), bilateral Yingxiang (LI20), Shenting (GV24), Baihui (GV20), and Sishencong (EX-HN1).After achieving the deqi sensation through acupuncture manipulation, electroacupuncture (SDZ-V, Huatuo brand, Suzhou Medical Supplies Factory Co., Ltd.) was applied. The treatment utilized a dense-disperse wave at a frequency of 2 Hz, with a current intensity of 2-4 mA adjusted to the patient's tolerance level. The needles were retained for 30 minutes.The treatment was administered once daily, 3-5 times per week, for a total duration of 8 weeks.

Device: "TXJN" electro-acupuncture

Control group

SHAM COMPARATOR

Sham electroacupuncture: Disposable acupuncture needles (Huatuo brand, Suzhou Medical Supplies Factory Co., Ltd., specification: 0.25 mm × 40 mm) were used.Acupoints were selected at 0.2-0.4 cun (5-10 mm) lateral to the original acupoints of the experimental group. The needles were inserted shallowly at a depth of 0.2-0.3 cun (5-8 mm), without eliciting the deqi sensation. The same electroacupuncture device was connected but with no electrical output. The needles were retained for 30 minutes.The treatment was administered once daily, 3-5 times per week, for a total duration of 8 weeks.
