Brief Summary
The goal of this clinical trial is to optimize the target brain areas for deep brain stimulation (DBS) for depression based on personalized brain imaging and stereo-electroencephalography(SEEG), to administer long-term DBS treatment in the target brain areas, to assess the effectiveness and safety of DBS for refractory depression and to validate the method of personalized optimization of DBS targets. The main questions it aims to answer are:
- 1.Where is the optimal DBS target brain region for each patient?
- 2.What are the optimal DBS parameters for each patient ?
- 3.What are the neural biomarkers of depression symptoms for each patient?
- 4.Are the optimized DBS strategies effective in treating refractory depression?

Outcome Measures
Primary Outcomes (2)
Change in Hamilton Rating Scale for Depression (HAMD) score during the DBS treatment phase relative to preoperative baseline
Improvement is defined as a 25-49% reduction in Hamilton Rating Scale for Depression (HAMD) score relative to the preoperative baseline; response is defined as a ≥50% reduction in HAMD score relative to the preoperative baseline; and remission is defined as a HAMD score ≤8.
at baseline and after 442 day
Changes in HAMD scores during the efficacy observation phase after DBS shutdown
Rebound is defined as a HAMD ≥18 in the subsequent follow-up period if the patient has an initial assessment of HAMD ≤8 in the efficacy observation phase after DBS shutdown, and rebound is defined as a HAMD score more than 2 times the initial assessment or 20 in the subsequent follow-up period if the patient has an initial assessment of HAMD \>8 in that phase.
Two months after 442 days
Secondary Outcomes (15)
the score of Montgomery-Asberg Depression Rating Scale (MADRS)

EXPERIMENTALInterventions
SEEG intraoperative experiment: patients will be implanted with microelectrodes and connected to an electrophysiological recorder under local anesthesia. Intraoperative neurophysiological baseline will be recorded for 5 minutes, and esketamine will be injected intravenously at a dose of 0.5 mg/kg, and neurophysiological recordings will be continued for 15 minutes to observe the neuronal electrophysiological changes in various brain regions and target points.
During the DBS treatment phase, the DBS device will apply electrical stimulation to the patient's target brain regions using a specific strategy, and if the efficacy of this phase is not satisfactory, electrical stimulation will continue to be applied during the efficacy observation phase after DBS shutdown.
Eligibility Criteria
You may qualify if:
- A psychiatrist-confirmed diagnosis of major depressive disorder in accordance with the Diagnostic And Statistical Manual Of Mental Disorders.5th Ed (DSM-V);
- A psychiatric examination by two trained psychiatrists and a diagnosis consistent with the DSM-V;
- A history of depression of at least 12 months duration in depressed patients (including MECT) who have failed to respond to a full dose and course of treatment with 2 or more antidepressants of different mechanisms;
