NCT01984710

Brief Summary

The goal of this study is to use the Activa Primary Cell + Sensing (PC+S) device to study Latent Field Potential (LFP) in the brains of people with Treatment Resistant Depression (TRD) before and during active stimulation. The ultimate goal is to understand the neural network that causes TRD and the changes that DBS cause in that network that results in the antidepressant effects.

Outcome Measures

Primary Outcomes (2)

  • Changes in Activa PC+S Local Field Potential (LFP) Recordings

    Electrophysiological changes in response to stimulation will be quantified. Continuous Activa PC+S Local Field Potential (LFP) recordings will be monitored from Day 1 post-op until the battery is depleted, which is anticipated to be after approximately 2-3 years.

    From Day 1, up to 3 years

  • Change in Hamilton Depression Rating Scale-17 Score

    The Hamilton Depression Rating Scale (HDRS-17) contains 17 items that are scored from 0 to 2, 3, or 4, where 0 is lack of difficulty and the highest number for an item is the most extreme difficulty. Total scores can range from 0 to 52 where higher scores represent greater symptom severity. Scores of 0-7 are considered normal, scores of 8-16 indicates mild depression, scores of 17-23 indicate moderate depression, and scores of 24 and greater indicate severe depression.

    Baseline; Recovery period with stimulation off: 24 hours post-operative, Weeks 1, 2, 3, 4; Stimulation phase: every 1-2 weeks up to week 30; Naturalistic follow up: every 1 to 6 months for up to 10 years

Secondary Outcomes (24)

  • Change in Hamilton Anxiety Rating Scale (HAM-A) Score

    Baseline; Recovery period with stimulation off: 24 hours post-operative, Weeks 1, 2, 3, 4; Stimulation phase: every 1-2 weeks up to week 30; Naturalistic follow up: every 1 to 6 months for up to 10 years

  • Change in Montgomery-Ă…sberg Depression Rating Scale (MADRS) Score

    Baseline; Recovery period with stimulation off: 24 hours post-operative, Weeks 1, 2, 3, 4; Stimulation phase: every 1-2 weeks up to week 30; Naturalistic follow up: every 1 to 6 months for up to 10 years

  • Change in Beck Depression Inventory (BDI-2) Score

    Baseline; Recovery period with stimulation off: 24 hours post-operative, Weeks 1, 2, 3, 4; Stimulation phase: every 1-2 weeks up to week 30; Naturalistic follow up: every 1 to 6 months for up to 10 years

  • Change in Beck Anxiety Inventory (BAI) Score

    Baseline; Recovery period with stimulation off: 24 hours post-operative, Weeks 1, 2, 3, 4; Stimulation phase: every 1-2 weeks up to week 30; Naturalistic follow up: every 1 to 6 months for up to 10 years

  • Change in Inventory of Depressive Symptomatology - Subject Rated (IDS-SR) Score

    Baseline; Recovery period with stimulation off: Weeks 1, 2, 3, 4; Stimulation phase: every 1-2 weeks up to week 30; Naturalistic follow up: every 1 to 6 months for up to 10 years
