Brief Summary

This study evaluates the efficacy of an accelerated schedule of theta-burst stimulation for treating manic episodes in bipolar disorder. In this open-label study, all participants will receive accelerated theta-burst stimulation.

Detailed Description

Repetitive transcranial magnetic stimulation (rTMS) is an established technology as therapy for treatment-resistant depression. The approved method for treatment is 10Hz stimulation for 40 minutes over the left dorsolateral prefrontal cortex (L-DLPFC). This methodology has been very successful in real-world situations. The limitations of this approach include the duration of the treatment (approximately 40 minutes per treatment session over 4-6 weeks). Recently, researchers have modified the treatment parameters to reduce treatment times with some preliminary success. In a recent study, an accelerated paradigm showed a significant antidepressant effect (90% remission rate) in individuals with treatment-resistant depression (TRD), in only 5 days. Additionally, 5 participants from this study carried a bipolar diagnosis and responded similarly, with no adverse events experienced or manic/hypomanic conversion observed during the treatment series. In parallel to this, evidence in the literature shows that right prefrontal rapid TMS is safe and efficacious in the treatment of bipolar mania showing laterality opposed to the proposed effect of rapid TMS in depression.

The current trial intends to utilise this modified design, i.e., an accelerated theta burst stimulation treatment over the right prefrontal cortex, for manic episodes in bipolar disorder. The trial also aims to look at the change in clinical measures and neuroimaging biomarkers.

Conditions

Bipolar Disorder, Manic; Bipolar Disorder I

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Right DLPFC aiTBS stimulation

Group Type: EXPERIMENTAL

Accelerated intermittent theta-burst stimulation over right DLPFC

Intervention Type: DEVICE

All participants will receive accelerated intermittent theta-burst stimulation to the right DLPFC. Stimulation intensity will be standardized at 90% of resting motor threshold adjust to the skull to cortical surface distance.

Stimulation will be delivered to right-DLPFC using the Brainsway stimulator.
