Background: Research suggests that altered eating and the pursuit of thinness in anorexia nervosa (AN) are, in part, a consequence of aberrant reward circuitry. The neural circuits involved in reward processing and compulsivity overlap significantly, and this has been suggested as a transdiagnostic factor underpinning obsessive compulsive disorder, addictions and eating disorders. The nucleus accumbens (NAcc) is central to both reward processing and compulsivity. In previous studies, deep-brain stimulation (DBS) to the NAcc has been shown to result in neural and symptomatic improvement in both obsessive compulsive disorder and addictions...

A Hartmann, B Millet
Repetitive movements are the hallmark of chronic tic disorders such as Tourette disorder (TD), whereas repetitive behaviors are characteristic of obsessive-compulsive disorder (OCD). Both disorders tend to frequently co-occur, as a substantial number of patients with TD also suffer from OCD and vice versa. While the clinical distinction between tics and OCD is usually easy, there are borderline forms, and correct symptom recognition is vital for choosing the appropriate treatment modalities for each disorder, be they pharmacological, psychotherapeutic (behavioral therapy) or brain stimulation (deep brain stimulation, repetitive transcranial magnetic stimulation)...

Our daily decisions involve an element of risk, a behavioural process that is potentially modifiable. Here we assess the role of the associative-limbic subthalamic nucleus in obsessive compulsive disorder (OCD) testing on and off deep brain stimulation (DBS) on anticipatory risk taking to obtain rewards and avoid losses. We assessed 12 OCD STN DBS in a randomized double-blind within-subject cross-over design. STN DBS decreased risk taking to rewards (p=0.02) and greater risk taking to rewards was positively correlated with OCD severity (p=0...

Over the last 30 years, deep brain stimulation (DBS) has been used to treat chronic neurological diseases like dystonia, obsessive-compulsive disorders, essential tremor, Parkinson's disease, and more recently, dementias, depression, cognitive disorders, and epilepsy. Despite its wide use, DBS presents numerous challenges for both clinicians and engineers. One challenge is the design of novel, more efficient DBS therapies, which are hampered by the lack of complete understanding about the cellular mechanisms of therapeutic DBS...

How do we decide what we do? This is the essence of action control, the process of selecting the most appropriate response among multiple possible choices. Suboptimal action control can involve a failure to initiate or adapt actions, or conversely it can involve making actions impulsively. There has been an increasing focus on the specific role of the subthalamic nucleus (STN) in action control. This has been fueled by the clinical relevance of this basal ganglia nucleus as a target for deep brain stimulation (DBS), primarily in Parkinson's disease but also in obsessive-compulsive disorder...

It has been three decades since the first application of deep brain stimulation (DBS) for tremors was described by Benabid. Over the years, the indications for the performance of DBS have been expanding. There are now more than 1,50,000 patients around the world who have undergone DBS for various disorders. The main appeal of DBS is in its reversibility and titratability. Though the initial interest in DBS was for pain, the main indications for DBS have been movement disorders. Despite its wide appeal and "perceived" advantage, United States Food and Drug Administration, the nodal agency for approving therapies, has been cautious and guarded in providing approvals...

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)...

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)...

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...
