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
The study wants to see if stimulating a brain area called the subcallosal cingulate can safely improve depression without causing mania, using real‑time brain signal monitoring.
Who it's for
Adults with bipolar I disorder who have ongoing depressive episodes that have not responded to standard treatments.
What's involved
Participants will have small electrodes surgically placed in two brain regions and will receive continuous electrical stimulation, with regular clinic visits for programming the device and recording brain signals.
Time commitment
The trial runs for several months and includes multiple follow‑up visits after the surgery.
