Background:

• Standard antidepressant treatments have limited efficacy, especially in patients with treatment-resistant depression (TRD).
• There is a critical need for novel therapeutic strategies to manage TRD effectively.

Purpose of the Study:

• To evaluate the efficacy of transcranial pulsed electromagnetic field (T-PEMF) therapy as an adjunctive treatment for patients with TRD.
• To assess the antidepressant effects of an 8-week T-PEMF intervention in a cohort of treatment-resistant individuals.

Main Methods:

• A multicenter, 8-week, single-arm cohort study was conducted.
• Fifty-eight participants meeting ICD-10 criteria for moderate-to-severe TRD were enrolled.
• The Hamilton Depression Scale (HAM-D17) was used to measure depression severity at baseline and endpoint.

Main Results:

• Significant reduction in HAM-D17 scores from baseline (20.6) to endpoint (12.6) was observed.
• At study endpoint, 49% of participants with non-chronic episodes and 28% with chronic episodes achieved a 50% reduction in HAM-D17 scores.
• Remission rates were 30% (HAM-D17 ≤ 7) and 16% (HAM-D6 ≤ 4) for non-chronic and chronic episodes, respectively.

Conclusions:

• T-PEMF therapy demonstrates potential as an effective augmentation strategy for ongoing pharmacotherapy in TRD.
• The findings support the consideration of T-PEMF as a novel treatment option for individuals with difficult-to-treat depression.
