In the USA, the Food and Drug Administration (FDA) has approved deep brain stimulation (DBS) devices for the treatment of Parkinson's disease (PD), essential tremor (ET), dystonia, and obsessive compulsive disorder (OCD). DBS has been approved for these same conditions in Europe, but, additionally the European Commission (EC) has granted the Conformité Européenne (CE) Mark for DBS as adjunctive treatment for partial-onset seizures in adults with medically refractory epilepsy. In this issue of EJN Budman and colleagues [1] briefly review the range of neurologic conditions that might constitute promising new indications for DBS...

The obsessive compulsive disorder (OCD) is a psychiatric disorder with a high prevalence (2‑3 %), frequently causing a disabling condition. Drug and psychotherapeutic treatment is generally effective. However about 1/3 of the patients are treatment-resistant, suffering from chronic psychological distress with important sociofunctional repercussions. The identification of dysfunctional neural networks in this disease opens the door to the use of neuromodulation techniques, as deep brain stimulation (DBS)...

REVIEW
Sina Kohl, Juan C Baldermann
This narrative review summarizes the recent literature on deep brain stimulation for treatment resistant obsessive-compulsive disorder highlighting both progress and challenges of this novel treatment. Common targets of psychiatric deep brain stimulation involve both white matter trajectories (anterior limb of the internal capsule, inferior thalamic peduncle, and medial forebrain bundle) and grey matter subcortical nuclei (nucleus accumbens, nucleus subthalamicus, and bed nucleus of the stria terminalis) each of which have been reported with a relevant beneficial effect on obsessive-compulsive symptoms...

Obese individuals share behavioral characteristics with drug/alcohol addicts as well as obsessive compulsive disease. Deep brain stimulation (DBS) has been used successfully in these disorders, thus warranting an evaluation in obesity. A woman with treatment-resistant depression as well as severe obesity was selected for DBS of the nucleus accumbens (NAcc) bilaterally with depression being the primary and obesity being the secondary target of treatment. Compared to earlier bariatric surgery, the patient showed accelerated weight loss after DBS...

OBJECTIVE: Refractory psychiatric disease is a major cause of morbidity and mortality worldwide, and there is a great need for new treatments. In the last decade, investigators piloted novel deep brain stimulation (DBS)-based therapies for depression and obsessive-compulsive disorder (OCD). Results from recent pivotal trials of these therapies, however, did not demonstrate the degree of efficacy expected from previous smaller trials. To discuss next steps, neurosurgeons, neurologists, psychiatrists and representatives from industry convened a workshop sponsored by the American Society for Stereotactic and Functional Neurosurgery in Chicago, Illinois, in June of 2016...

BACKGROUND: Despite the development of effective pharmacologic and cognitive behavioral treatments for obsessive-compulsive disorder (OCD), some patients continue to be treatment-refractory and severely impaired. Fiber tracts connecting orbitofrontal and dorsal anterior cingulate cortex with subcortical nuclei have been the target of neurosurgical lesions as well as deep brain stimulation in these patients. We report on the safety and efficacy of ventral gamma capsulotomy for patients with intractable OCD...

The use of deep brain stimulation (DBS) of the thalamus has been proven to be a safe and efficacious treatment for the management of many diseases. The most common indication for thalamic DBS remains essential tremor (ET), one of the most common movement disorders in the world. ET patients should be considered for surgical intervention when their tremor has demonstrated to be refractory to medication, a characteristic estimated to be present in roughly 50% of ET cases. Advantages of DBS over thalamotomy include its reversibility, the ability to adjust stimulation settings to optimize efficacy and minimize side effects, the ability to perform bilateral procedures safely, and an association with a lower risk of postoperative cognitive problems...

Many of the currently available treatments for obsessive-compulsive and related disorders (OCRDs) such as pharmacotherapy augmentation strategies, partial hospitalization programs, deep brain stimulation, and neurosurgery are efficacious for individuals suffering from more severe forms of these conditions. Unfortunately, the application of these treatments in milder forms of illness and subclinical samples, which affect a substantial portion of the population, is not justifiable by their costs (e.g. cognitive-behavioral therapy) and/or potential for side effects (serotonin-reuptake inhibitors associated sexual side effects)...

BACKGROUND: Deep brain stimulation (DBS) has been introduced as a treatment option for treatment-resistant obsessive-compulsive disorder (OCD). However, the optimal stimulation target and the corresponding simulation settings remain unclear. Furthermore, there is limited knowledge about the acute effects of DBS. METHODS: In three patients with treatment-resistant OCD, DBS electrodes were implanted in the bed nucleus of the stria terminalis/internal capsule (BNST/IC)...

Deep brain stimulation is a method that involves using an electric stimulus on a specific target in the brain with stereotaxis. It is a minimally invasive, safe, adjustable and reversible nerve involvement technology. At present, this technique is widely applied to treat movement disorders and has produced promising effects on mental symptoms, including combined anxiety and depression. Deep brain stimulation has therefore been employed as a novel treatment for depression, obsessive-compulsive disorder, habituation, Tourette's syndrome, presenile dementia, anorexia nervosa and other refractory mental illnesses...

The ability to adaptively minimize not only motor but cognitive symptoms of neurological diseases, such as Parkinson's Disease (PD) and obsessive-compulsive disorder (OCD), is a primary goal of next-generation deep brain stimulation (DBS) devices. On the basis of studies demonstrating a link between beta-band synchronization and severity of motor symptoms in PD, the minimization of beta band activity has been proposed as a potential training target for closed-loop DBS. At present, no comparable signal is known for the impulsive side effects of PD, though multiple studies have implicated theta band activity within the subthalamic nucleus (STN), the site of DBS treatment, in processes of conflict monitoring and countermanding...

BACKGROUND: Twiddler's syndrome consists of rotation or manipulation of an implantable pulse generator (IPG) in its subcutaneous pocket by a patient, thus causing hardware malfunction. METHODS: This syndrome is being reported more frequently in patients treated with deep brain stimulation (DBS). RESULTS: We report the case of a woman who had received bed nucleus of stria terminalis (BNST) electrodes for obsessive-compulsive disorder (OCD) and developed twiddler's syndrome a few months after surgery, causing hardware malfunction due to obsessive manipulation of the IPG...

Deep brain stimulation (DBS) is a well-established therapy for Parkinson's disease and other movement disorders. An accumulating body of evidence supports the extension of DBS application for the treatment of refractory psychiatric disorders. The ventral capsule/ventral striatum (VC/VS) is the most common anatomical target for obsessive-compulsive disorder (OCD), addiction, and depression. However, no specific electrode is available for the clinical targeting of these areas for DBS. According to the anatomical features of the VC/VS, a novel electrode was developed for simultaneous and independently programmed stimulation of the nucleus accumbens (NAc) and the anterior limb of the internal capsule (ALIC)...

Dystonia is a hyperkinetic movement disorder, characterized by sustained or intermittent muscle contractions causing abnormal, often repetitive, movements, postures, or both. Executive dysfunction is a feature of cognitive function in idiopathic and DYT1 dystonia. Psychiatric morbidity is increased in dystonia, and depression, anxiety, obsessive compulsive disorders are the most common disorders. Sleep problems and pain are also frequently experienced. Evidence suggest that mood and anxiety disorders are intrinsic to the neurobiology of dystonia, but also that psychiatric co-morbidity can be secondary to pain experience and the psychosocial functioning and quality of life of the patients...

Angela An Qi See, Nicolas Kon Kam King
INTRODUCTION: Recent advances in surgical imaging include the use of diffusion tensor imaging (DTI) in deep brain stimulation (DBS) and provide a detailed view of the white matter tracts and their connections which are not seen with conventional magnetic resonance imaging. Given that the efficacy of DBS depends on the precise and accurate targeting of these circuits, better surgical planning using information obtained from DTI may lead to improved surgical outcome. We aim to review the available literature to evaluate the efficacy of such a strategy...

Kenneth Barrett
Ambulatory deep brain stimulation (DBS) became possible in the late 1980s and was initially used to treat people with movement disorders. Trials of DBS in people with treatment-resistant psychiatric disorder began in the late 1990s, initially focusing on obsessive-compulsive disorder, major depressive disorder and Tourette syndrome. Despite methodological issues, including small participant numbers and lack of consensus over brain targets, DBS is now being trialled in a wide range of psychiatric conditions...
