The goal of the study is to address the unmet need of TRD patients by identifying brain networks critical for treating depression and to use next generation precision DBS with steering capability to engage these targeted networks. The study's goal will be achieved through 3 specific aims:
1. Demonstrate device capability to selectively and predictably engage distinct brain networks
2. Delineate depression-relevant networks and demonstrate behavioral changes with network-targeted stimulation
3. Demonstrate that chronic DBS using steered, individualized targeting is feasible and safe for reducing depressive symptoms
Treatment-resistant depression (TRD) is a major worldwide burden. Major depression has a lifetime prevalence of ~15% across developed countries. Up to a third of patients fail to respond adequately to evidence-based treatments, including pharmacological, behavioral, and electroconvulsive therapy. The investigators employ an innovative approach, including subacute invasive neurophysiological monitoring with which they aim to gain insight into the networks underlying depression symptomatology, confirm the ability to predict the effects of precision DBS on network activity, and harmonize these insights to implement network-guided DBS for TRD.

A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.
Marked depression appearing in the involution period and characterized by hallucinations, delusions, paranoia, and agitation.
A serotonin uptake inhibitor that is used as an antidepressive agent. It has been shown to be effective in patients with major depressive disorders and other subsets of depressive disorders. It is generally more useful in depressive disorders associated with insomnia and anxiety. This drug does not aggravate psychotic symptoms in patients with schizophrenia or schizoaffective disorders. (From AMA Drug Evaluations Annual, 1994, p309)
Therapy for MOVEMENT DISORDERS, especially PARKINSON DISEASE, that applies electricity via stereotactic implantation of ELECTRODES in specific areas of the BRAIN such as the THALAMUS. The electrodes are attached to a neurostimulator placed subcutaneously.
Inability to experience pleasure due to impairment or dysfunction of normal psychological and neurobiological mechanisms. It is a symptom of many PSYCHOTIC DISORDERS (e.g., DEPRESSIVE DISORDER, MAJOR; and SCHIZOPHRENIA).
