Summary

The primary purpose of this study is to investigate the effect of deep brain stimulation (DBS) implantation in patients with Treatment-resistant Depression (TRD) targeting the ventral capsule/ventral striatum (VC/VS), Brodmann area 25/subcallosal cingulate (SCC), Anterior Limb of Internal Capsule (ALIC), inferior thalamic peduncle (ITP), nucleus accumbens (NAc), lateral habenula (LHb), medial forebrain bundle (MFB), or other unreported nuclei targets.

Detailed description

At least 40-60% of people with major depressive disorders (MDD) continue to have symptoms after treatment. The pharmacology treatment cannot produce sustained antidepressant effects in 50% of patients with depression. Therefore, more effective therapeutic methods are urgently needed. In a comprehensive survey of diverse neuromodulation therapies, targeting specific nuclei with deep brain stimulation (DBS) has the most potential for Treatment-resistant Depression (TRD) with apparent symptoms. The stimulation targets of DBS for patients with obsessive-compulsive disorder include the ventral capsule/ventral striatum (VC/VS), Brodmann area 25/subcallosal cingulate (SCC), Anterior Limb of Internal Capsule (ALIC), inferior thalamic peduncle (ITP), nucleus accumbens (NAc), lateral habenula (LHb), and medial forebrain bundle (MFB). However, the DBS case reports are limited and lack high-quality, evidence-based medical evidence. So, this cohort study focuses on the effectiveness of DBS-targeted VC/VS, SCC, ALIC, ITP, NAc, LHb, MFB, or other unreported nuclei targets on TRD. Another goal of this program is to study the neuronal activity of the VC/VS, SCC, ALIC, ITP, NAc, LHb, MFB, or other unreported nuclei targets, respectively. At the same time, some subjects are presented with a task involving an unexpected reward. This separate study is an option and will not affect current study participation. Some participants will also be invited to join a related study that involves positron emission tomography (PET) scanning to determine how the stimulation changes activity in the brain. Participation in the separate PET study is optional and will not affect current study participation.

Conditions

• Treatment Resistant Depression

Interventions

Type	Name	Description
DEVICE	Deep Brain Stimulation (DBS)	The DBS lead is stereotactically introduced into the target in the brain (SCC, VC/VS, ALIC, ITP, NAc, LHb, MFB, or other unreported nuclei targets) and fixed to the skull; the lead is then connected to a neurostimulator implanted subcutaneously in the subclavicular region.
