Berlin Deep Brain Stimulation Depression Study (BDDS)

January 23, 2018 updated by: Malek Bajbouj, Charite University, Berlin, Germany

Investigation of Efficacy and Safety of Deep Brain Stimulation in Patients With Treatment Resistant Major Depression in a Multicenter, Double-blind, Prospectivly-designed Delayed-onset Study (Tiefe Hirnstimulation Zur Behandlung Therapieresistenter Depressionen-eine Multizentrische, Doppelblinde, Prospektive Studie Mit Einem Delayed-onset Design)

In this study efficacy and safety of deep brain stimulation of the cingulate cortex in 20 patients with treatment resistant major depression will be investigated. In addition, the stress axis, the cortical GABAergic system, neurotrophins and event-related potentials will be assessed.
