About this study

Official title: Efficacy and Amygdala-entorhinal Circuit of Electroacupuncture Intervention in SCD With Depression: A Randomized Controlled Trial

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.

  2. Undergo cognitive function and depression assessments before and after treatment.
  3. Complete multimodal cranial magnetic resonance imaging examinations before and after treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • "TXJN" electro-acupunctureDevice

    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.

  • Sham electroacupunctureDevice

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Before and 8 weeks after treatment

  2. 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%).

    Measured: Before and 8 weeks after treatment

  3. Multimodal magnetic resonance imaging indicators

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

    Measured: Before and 8 weeks after treatment

Secondary outcomes (12)
  1. Mini-Mental State Examination (MMSE) Total Score

    The total score (range: 0-30) of the Mini-Mental State Examination, where a higher score indicates better cognitive function.

    Measured: Before and 8 weeks after treatment

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

    The score for the long-delay free recall trial of the Auditory Verbal Learning Test (range: 0-15 words), where a higher score indicates better episodic memory function.

    Measured: Before and 8 weeks after treatment

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

    The score for the delayed recall trial of the Rey-Osterrieth Complex Figure Test, which is typically scored on a standardized system (e.g., 0-36 points based on accuracy and placement of reproduced elements), where a higher score indicates better visual-spatial memory and recall ability.

    Measured: Before and 8 weeks after treatment

  4. Boston Naming Test (BNT) Total Correct Score

    The total number of correctly named items (range: 0-30) of the 30-item Boston Naming Test, where a higher score indicates better confrontational word retrieval and language ability.

    Measured: Before and 8 weeks after treatment

  5. Animal Fluency Test (AFT) Total Score

    The total number of correct, unique animal names generated within 60 seconds (common score range: 0-50+), where a higher score indicates better semantic verbal fluency and executive functioning.

    Measured: Before and 8 weeks after treatment

  6. Trail Making Test Part A (TMT-A) Completion Time

    The time to completion (in seconds) for Trail Making Test Part A, where a shorter completion time indicates better visual attention, processing speed, and motor function.

    Measured: Before and 8 weeks after treatment

  7. Trail Making Test Part B (TMT-B) Completion Time

    The time to completion (in seconds) for Trail Making Test Part B, where a shorter completion time indicates better cognitive flexibility, task-switching ability, and executive function.

    Measured: Before and 8 weeks after treatment

  8. Clock Drawing Test (CDT) Total Score

    The total score on the standardized 30-point Clock Drawing Test (CDT30-AJ/CI version, range: 0-30), where a higher score indicates better visuospatial/executive function and cognitive integrity.

    Measured: Before and 8 weeks after treatment

  9. Symbol Digit Modalities Test (SDMT) Correct Response Count

    The total number of correct symbol-digit pairings completed within 90 seconds (common score range: 0-110+), where a higher score indicates better processing speed, sustained attention, and visual scanning.

    Measured: Before and 8 weeks after treatment

  10. Pittsburgh Sleep Quality Index (PSQI) Global Score

    The global score (range: 0-21) of the Pittsburgh Sleep Quality Index, where a higher score indicates poorer sleep quality.

    Measured: Before and 8 weeks after treatment

  11. TCM Constitution Classification and Determination Scale - Transformed Scores

    The transformed scores (range: 0-100 for each of the nine constitution subscales) calculated according to the standardized "TCM Constitution Classification and Determination Scale" (published by the China Association of Chinese Medicine). A higher transformed score on a specific subscale indicates a more pronounced tendency towards that constitution type (e.g., Yang Deficiency, Qi Deficiency, etc.).

    Measured: Before and 8 weeks after treatment

  12. TCM Syndrome Type Scale for Mild Cognitive Impairment Subscale Scores

    Scores (range: 0-30 per syndrome) for seven TCM syndrome types (e.g., Spleen-Kidney Deficiency) as assessed by the standardized "TCM Syndrome Type Scale for Mild Cognitive Impairment", where a higher score indicates more severe syndrome manifestation.

    Measured: Before and 8 weeks after treatment
