Summary
This trial will study the effects of transcranial brain stimulation on brain activity and emotions in adults with and without bipolar disorder, in order to better understand the predisposing brain mechanisms of bipolar disorder.
Who is the study for?
This trial is for adults aged 18-35 with Bipolar Disorder I/II in remission or mild-moderate hypomania. They must score low on depression and mania scales, can be unmedicated or on certain stable medications (excluding antidepressant monotherapy), and have no severe psychiatric disorders, substance abuse issues, head injuries, neurological diseases, or family history of epilepsy.
What is being tested?
The study tests the effects of Theta Burst Stimulation (TBS) on brain activity and emotions in people with Bipolar Disorder. It compares Continuous TBS (cTBS), which is an active treatment, to a sham version that mimics the procedure without real stimulation to see if cTBS reduces symptoms like negative emotions.
What are the potential side effects?
While not explicitly listed in the provided information, common side effects of TBS may include headache, scalp discomfort at the stimulation site during treatment sessions, lightheadedness immediately following treatment sessions, and rare risk of seizure.

Trial Design
6Treatment groups
Experimental Treatment
Group I: Left vlPFC/Left vlPFC sham/Left SSExperimental Treatment2 Interventions
A random number sequence will be generated for randomization of the 3 cTBS scan session order to which each participant is assigned:
* left vlPFC cTBS (cTBS applied to the left ventrolateral prefrontal cortex)
* left SS cTBS (cTBS applied to the left somatosensory area)
* left vlPFC sham TBS (go through the motions of applying cTBS to the left ventrolateral prefrontal cortex but very low current is administered so that the participant feels like cTBS is being administered even though the current is too low to stimulate brain cells) Participants will know that one session will be a sham, but they will be blinded to which session is the sham.
Group II: Left vlPFC sham/Left vlPFC/Left SSExperimental Treatment2 Interventions
A random number sequence will be generated for randomization of the 3 cTBS scan session order to which each participant is assigned:
* left vlPFC cTBS (cTBS applied to the left ventrolateral prefrontal cortex)

* left vlPFC sham TBS (go through the motions of applying cTBS to the left ventrolateral prefrontal cortex but very low current is administered so that the participant feels like cTBS is being administered even though the current is too low to stimulate brain cells) Participants will know that one session will be a sham, but they will be blinded to which session is the sham.
