NCT05849402

Brief Summary

The purpose of this study is to investigate the effectiveness of accelerated intermittent theta-burst transcranial magnetic stimulation (aiTBS) in inducing anti-depressant responses in individuals with treatment-resistant depression of bipolar II disorder. This is a double-blind, randomized, sham-controlled trial that targets a single location on the left dorsolateral prefrontal cortex (LDLPFC) using the MagPro rTMS system.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline Montgomery Asberg Depression Rating Scale (MADRS)

    A ten item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. The MADRS uses a 0 to 6 severity scale, scored following the interview. Scoring/Interpretation: Higher scores indicate increasing depressive symptoms. Cut-off points include: 0 to 6 - symptom absent, 7 to 19 - mild depression, 30 to 34 - moderate, 35 to 60 - severe depression.

    Baseline and immediately post-treatment, 1-month

Secondary Outcomes (2)

  • Change from baseline Young Mania Rating Scale (YMRS)

    Baseline and immediate post-treatment, 1-month

  • Change in resting-state functional connectivity

    After all stimulation sessions have been completed (approximately 48 hours after the final session)

Study Arms (2)

  • +1 more criteria

You may not qualify if:

  • Primary diagnosis other than bipolar II disorder
  • Any structural lesion e.g. structural neurological condition, more subcortical lesions than would be expected for age, stroke effecting stimulated area or connected areas or any other clinically significant abnormality that might affect safety, study participation, or confound interpretation of study results.

  • History of epilepsy or seizures
  • Shrapnel or any ferromagnetic item in the head
  • Pregnancy
  • Autism Spectrum disorder
