NCT07589647

Brief Summary

This study aims to stabilize the patients with bipolar disorder (BD) comorbid with obesity in the stable phase by using temporal interference stimulation (TIS ) intervention. It intends to investigate the changes in key metabolic molecules such as GLP-1 circadian rhythm, and further explore the molecular mechanism of their metabolic disorders.

Outcome Measures

Primary Outcomes (1)

  • GLP level

    0-2week

Study Arms (2)

Temporal Interference Stimulation

EXPERIMENTAL

TIS treatment lasts for 20 minutes, with the maximum output current being 2mA, which is adjusted according to the individual head model. The two pairs of electrical stimulation frequencies in tTIS are 1000Hz and 1040Hz.

Other: Temporal Interference Stimulation

Sham Temporal Interference Stimulation

PLACEBO COMPARATOR

The stimulus intensity was 20% of MT in the Sham Comparator arm, and the remaining parameters werethe same as the Active Comparator arm.
