Trial studying safety and effects for Bipolar I Disorder
Official title Safety and Feasibility of DBS for Bipolar Depression
ClinicalTrials.gov ID: NCT07745374
What this study is testing
- What it's testing
- This study addresses a critical unmet need in the treatment of bipolar disorder by investigating whether Subcallosal Cingulate (SCC) Deep Brain Stimulation (DBS) can safely and effectively treat treatment-resistant bipolar depression without inducing manic switches. The researchers propose to accomplish this by incorporating monitoring of the SCC local field potentials (LFP) for depression tracking and amygdala LFP monitoring for mania prediction while treating Bipolar I patients with SCC DBS Stimulation.
