This study will investigate the use of deep brain stimulation (DBS) to reduce symptom severity and enhance the quality of life for patients with treatment-refractory major depression.

Condition Intervention Phase
Device: Deep Brain Stimulation with Medtronic Activa Neurostimulator
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Deep Brain Stimulation for Treatment-Refractory Major Depression

Further study details as provided by University Hospital, Bonn:

Primary Outcome Measures:
  • Hamilton Depression Rating Scale (HDRS) [ Time Frame: analyzed at 12 and 24 month after stimulation onset ]

Secondary Outcome Measures:
  • Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: analyzed at 12 and 24 month after stimulation onset ]

Enrollment: 13
Study Start Date: July 2005
Study Completion Date: January 2011
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: DBS Device: Deep Brain Stimulation with Medtronic Activa Neurostimulator
Deep brain stimulation (DBS) at 130 Hz
Other Name: Activa Neurostimulator

Detailed Description:
Despite advances in pharmacotherapy and psychotherapy for major depression, a substantial number of patients fail to improve significantly even after years of conventional and experimental interventions. Bilateral deep brain stimulation (DBS) to the region of the anterior capsule/ventral striatum is an adjustable and reversible procedure that may be a more effective treatment for patients with major depression. This study will determine the effectiveness, safety, and tolerability of DBS in patients with treatment-refractory major depression.
