Dense cranial electroacupuncture stimulation for major depressive disorder--a single-blind, randomized, controlled...

Area of Science:

• Neuroscience
• Psychiatry
• Integrative Medicine

Background:

• Electroacupuncture shows promise for treating depressive disorders.
• Major Depressive Disorder (MDD) is a significant global health concern.
• Selective Serotonin Reuptake Inhibitor (SSRI) therapy is a common treatment for MDD.

Purpose of the Study:

• To evaluate if dense cranial electroacupuncture stimulation (DCEAS) can boost the antidepressant efficacy of SSRI treatment in early-stage MDD.
• To compare DCEAS combined with fluoxetine (FLX) against noninvasive electroacupuncture (n-EA) plus FLX.

Main Methods:

• A single-blind, randomized, controlled trial involving 73 MDD patients.
• Participants received 9 sessions of either DCEAS or n-EA over 3 weeks, alongside fluoxetine.
• Outcomes measured via HAMD-17, CGI-S, SDS, and response/remission rates.

Main Results:

• DCEAS group showed significantly greater reductions in HAMD-17 and SDS scores compared to the n-EA group.
• The DCEAS intervention resulted in a higher clinically significant response rate (19.4% vs. 8.8%).
• Adverse event incidence was comparable between the DCEAS and n-EA groups.

Conclusions:

• Dense cranial electroacupuncture stimulation (DCEAS) is a safe and effective method to augment antidepressant efficacy.
• DCEAS can be considered a valuable add-on therapy during the initial phase of SSRI treatment for depression.
• This approach offers a promising complementary strategy for managing major depressive disorder.
