Brief summary
The goal of this pilot Study and Randomized Controlled Trial is to investigate the impact of electroacupuncture on cognitive function, quality of life (QoL), and depression severity in patients with major depressive disorder (MDD). The main question\[s\] it aims to answer are: * Primary : electroacupuncture has the potential to treat subjective cognitive complaints and cognitive impairment in MDD outpatients * Secondary : electroacupuncture has the potential to treat depressive in MDD outpatients The 60 participants will randomly be assigned to either the treatment group or the control group in a 1:1 ratio. The treatment group will undergo electroacupuncture (EA), while the control group will receive sham acupuncture within 10 weeks period. Both groups will receive antidepressants with adjunctive medication (i.e., benzodiazepines, tricyclics, or antipsychotics) as the standard treatment. All participants will be assessed for executive functions and memory using specific cognitive tests, including the Trail Making Test B (TMT-B), Stroop Color and Word Test (SCWT), category delayed recall in the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), and subjective reports of concern regarding concentration, memory, problem-solving, learning, communication, and quality of life (QoL) concerns using the WHO Disability Assessment Schedule (WHODAS 2.0; sections D1.1-1.6 and H1-3), and depressive symptoms were assessed using the Thai-PHQ-9.
Interventions
PROCEDUREElectroacupuncture group
The acupuncture needle was placed on the scalp at a Chinese traditional acupuncture point. Subsequently, a small electrode was attached to the needle. A minor amount of electricity runs through the electrode, producing a slight vibration or soft hum during the treatment.
PROCEDURESham acupuncture

Masking description
In the sham acupuncture control group (CG), participants received acupress or a brief needle insertion at He gu on both hands during the first and 10th weeks, marking the endpoint of the study.
Intervention model description
In the electroacupuncture group (EG), participants received acupuncture at 10 scalp points (Baihui \[GV20\], Ex-hn 1, 3 points of intelligence \[Shenting \[GV24\], Benshen \[GB13\] on both sides, Touwei \[ST8\] on both sides). Electroacupuncture was applied for 20 minutes at Benshen \[GB13\] and Touwei \[ST8\] on both sides. They also received acupuncture at Tai chong \[LV3\], Tai Yuan \[LU9\], and Tai Xi \[KI3\] on both sides, as shown in picture 1. Acupuncture sessions were weekly for 10 weeks. In the sham acupuncture control group (CG), participants received acupress or a brief needle insertion at He gu on both hands during the first and 10th weeks, marking the endpoint of the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Trail making test B (TMT-B) | Pre-intervention at the beginning point (T0) and the endpoint will be the 10th week (T10) | The TMT- B is scored based on the time (in seconds) it takes to complete the test, including corrections for errors prompted by the examiner. A shorter time implies better performance. |
| The Stroop Color and Word Test (SCWT) | Pre-intervention at the beginning point (T0) and the endpoint will be the 10th week (T10) | SCWT used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute.Score refers to the number of words achieved, and a higher number of words indicates a better score. |
| ADAS-cog category delayed recall | Pre-intervention at the beginning point (T0) and the endpoint will be the 10th week (T10) | ADAS-cog category delayed recall is used to assess memory. The score reflects the number of words that can be remembered. The more words remembered, the better the score. |
| Subjective cognitive complaint | Pre-intervention at the beginning point (T0) and the endpoint will be the 10th week (T10) | WHODAS 2.0; sections D1.1-1.6 and H1-3, which is a questionnaire asking about the number of days in the past 30 days when participants experienced difficulties with attention, understanding, and initiating conversation. Score is the rating of the number of days with issues, and a decrease in score indicates improvement or a better outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Thai Patient Health Questionnaire (PHQ-9) | Pre-intervention at the beginning point (T0) and the endpoint will be the 10th week (T10) | The Thai PHQ-9 (Patient Health Questionnaire-9) objectifies and assesses degree of depression severity via questionnaire. A lower score means better. |
