Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Deep Brain Stimulation (DBS) using Medtronics Kinetra Model 7428.

DBS is a neurosurgical procedure that involves the precise implantation of very small electrodes into targeted regions of the brain. These electrodes are powered by a stimulating battery which is implanted under the skin in the chest. The type of stimulation that is delivered can be adjusted using an external remote control which is operated by the treating doctor.

The stimulation parameters include the combination of electrodes activated, electrode reference scheme, voltage, frequency and pulse width. In the current study all stimulation parameters will be individualised for each patient. They will be titrated over a period of weeks or months (depending on individual patient response) and once the optimal settings for each patient are identified stimulation will remain ongoing indefinitely.

Eligibility
Key inclusion criteria
1. Have a DSM-IV diagnosis of a major depressive episode as confirmed by both SCID interview and independent psychiatrist review (X2)

2. Age 18-70

3. Have treatment resistant depression at Stage V of the Thase and Rush classification. This is a very strict definition of TRD and requires failure to respond to adequate courses of at least several different classes of antidepressants and a course of bilateral ECT.

4. Have a Montgomery-Asberg Depression Rating Scale score of > 25 (moderate – severe depression)

5. Demonstration of capacity to give informed consent: this will need to be assessed and documented by two independent psychiatrists and signing of the consent form will take place in the presence of an independent consent monitor. Consent capacity will also be reviewed by the Victorian Psychosurgery Review Board.
Minimum age
18 Years
Maximum age

Key exclusion criteria
1. Have an unstable medical condition, neurological disorder or any history of a seizure disorder or are currently pregnant or lactating
