Deep brain stimulation (DBS), a nonablative, reversible, and adjustable neurosurgical
procedure, has recently been considered as a potential therapeutic alternative for
the management of resistant obsessive-compulsive disorder (OCD). The ventral striatum
(VS) has been proposed as a subcortical target of special interest for DBS (

). It has been extensively demonstrated to play a major role in the pathophysiology
of OCD regarding convergent functional neuroimaging data and electrophysiologic recordings
(

). Here, we report the long-term course of OC symptoms during DBS of the VS and following
its discontinuation in two patients suffering from severe, chronic, and incapacitating
OCD and showing unsatisfactory responses to 1) the serotonin reuptake inhibitor (SRI)
antidepressants fluoxetine, sertraline, paroxetine, fluvoxamine, and clomipramine;
2) augmentation with buspirone or lithium; and 3) adjunctive cognitive-behavioral
therapy (

to assess clinical severity (
