Response and Safety Outcomes in Treatment-Resistant Depression After Subcallosal Cingulate Gyrus Deep Brain Stimulation

Conclusions: SCG-DBS produced a robust and protracted improvement in most patients, which reinforces the possibility that SCG-DBS could be an alternative for patients with treatment-resistant unipolar or bipolar depression. Identification of clinical and neurobiological response predictors should guide the continuation of DBS for TRD, to obtain its indication soon.
