Obsessive-compulsive disorder (OCD) is an anxiety disorder associated with recurrent intrusive thoughts and repetitive behaviors. Although conventional pharmacological and/or psychological treatments are well established and effective in treating OCD, symptoms remain unchanged in up to 30% of patients. Deep brain stimulation (DBS) of the anterior limb of the internal capsule has recently been proposed as a possible therapeutic alternative in treatment-resistant OCD. In the present study, the authors tested the hypothesis that DBS of the ventral caudate nucleus might be effective in a patient with intractable severe OCD and concomitant major depression. Psychiatric assessment included the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Hamilton Depression Rating Scale (HDRS), the Hamilton Anxiety Rating Scale (HARS), and the Global Assessment of Functioning (GAF) Scale for determining the symptom severity of OCD, depression, and anxiety as well as the quality of pychosocial and occupational functioning, respectively. Neuropsychological assessment consisted of a wide range of tests primarily exploring memory and executive functions. Deep brain stimulation of the ventral caudate nucleus markedly improved symptoms of depression and anxiety until their remission, which was achieved at 6 months after the start of stimulation (HDRS < or = 7 and HARS < or = 10). Remission of OCD (Y-BOCS < 16) was also delayed after 12 or 15 months of DBS. The level of functioning pursuant to the GAF scale progressively increased during the 15-month follow-up period. No neuropsychological deterioration was observed, indicating that DBS of the ventral caudate nucleus could be a promising strategy in the treatment of refractory cases of both OCD and major depression.

The ventral striatum, including the head of the caudate nucleus and the nucleus accumbens, is a putative target for deep brain stimulation (DBS) in the treatment of obsessive-compulsive disorder (OCD) and major depression (MD). However, the respective roles of these structures in the pathophysiology of OCD and MD remain to be clarified. To address this issue, DBS of the ventral striatum was tested in 2 patients with severely distressing and intractable forms of OCD and MD. Comparisons of clinical outcomes and anatomical data on electrode positioning showed that caudate nucleus stimulation preferentially alleviated OCD manifestations, whereas nucleus accumbens stimulation improved depressive symptoms. These findings suggest that the caudate nucleus and nucleus accumbens participate differently in the pathogenesis of both of these psychiatric conditions.

ObjectivesTo evaluate the effect of cosmetic surgery and the stability of body dysmorphic disorder (BDD) diagnosis in patients with a minimal defect in appearance, with and without BDD, 5 years after their request for plastic surgery.Subjects and methodsThirty patients requesting cosmetic surgery with minimal defect in appearance, of whom 12 had BDD and 18 did not, were re-evaluated 5 years later by telephone interview regarding their cosmetic surgery interventions, satisfaction with the intervention, BDD diagnosis, handicap, and psychiatric comorbidity.ResultsOf the 30 patients, we were able to re-evaluate 24 subjects (80%), 10 with BDD and 14 non-BDD. Seven BDD subjects had undergone cosmetic surgery vs 8 non-BDD. Patient satisfaction with the intervention was high in both groups. Nevertheless at follow-up, 6 of the 7 operated BDD patients still had a BDD diagnosis and exhibited higher levels of handicap and psychiatric comorbidity compared to their non-BDD counterparts. Moreover, 3 non-BDD patients had developed a BDD at follow-up.ConclusionThis prospective study confirms that cosmetic surgery is not efficient on BDD despite declared patient satisfaction. Cosmetic surgery had no significant effects on BDD diagnosis, handicap or psychiatric comorbidity in BDD patients at 5-year follow-up. Furthermore, BDD appeared at follow-up in some initially non-BDD diagnosed subjects. Patients' declared satisfaction with surgery may contribute to explain why some plastic surgeons may not fully adhere to the contraindication of cosmetic surgery in BDD.
