Clinical Trial Summary

Bipolar Disorder (BD) is a common and highly debilitating psychiatric disorder, however, the predisposing brain mechanisms are poorly understood. Here, the investigators will conduct a proof of concept study that will examine the effect of electroencephalography (EEG)-guided theta burst stimulation (TBS) on reducing mania/hypomania-related affect and reward driven behavior in adults with BD. The investigators hypothesize that TBS will reduce mania/hypomania-related affect and reward driven behavior in adults with BD.


Clinical Trial Description

This study aims to examine the effect of electroencephalography (EEG)-guided theta burst stimulation (TBS) on reducing mania/hypomania-related affect and reward driven behavior in adults with BD. Eligible participants will undergo 6 study visits: a screening visit, a baseline MRI visit, TBS motor thresholding visit, and 3 cTBS/EEG visits. Participants will receive brain stimulation and have brain activity recorded by EEG at each of the 3 cTBS/EEG study visits. The research associates (except for the research associate administering the TBS) and participants will be blinded to the brain area receiving TBS, which will be randomized and counterbalanced beforehand. Certain information is withheld to protect the scientific integrity of the study design. The goal of the study is to reduce overactivity in the reward neural network (RNet) and increase activity in the central executive control network (CEN) using theta burst stimulation (TBS). The region in the RNet to be targeted by inhibitory (continuous, cTBS) is the left ventrolateral prefrontal cortex (vlPFC); and the region in the CEN to be targeted by excitatory (intermittent, iTBS) is the right dorsolateral prefrontal cortex (dlPFC) ;
