Deep brain stimulation (DBS) of the medial forebrain bundle (MFB) induces rapid improvement of depressive symptoms in patients suffering from treatment-refractory major depressive disorder. It has been hypothesized that activation of the dopamine (DA) system contributes to this effect. To investigate whether DBS in the MFB affects DA release in the striatum, we combined DBS with fast-scan cyclic voltammetry (FSCV) in freely moving rats. Animals were implanted with a stimulating electrode at the border of the MFB and the ventral tegmental area, and a FSCV microelectrode in the ventromedial striatum to monitor extracellular DA during the acute onset of DBS and subsequent continued stimulation...

BACKGROUND/AIMS: Intraoperative magnetic resonance imaging (iMRI) is increasingly used to implant deep brain stimulator (DBS) electrodes. The approach has the advantages of a high targeting accuracy, minimization of brain penetrations, and allowance of implantation under general anesthesia. The hemorrhagic complications of iMRI-guided DBS implantation have not been studied in a large series. We report on the incidence and characteristics of hemorrhage during these procedures. METHODS: Hemorrhage incidence was assessed in a series of 231 iMRI procedures (374 electrodes implanted)...

Although deep-brain stimulation (DBS) of the lateral habenula (LHb) has been successfully applied to treatment-resistant depression for years, the mechanism is still unclear. Previous researches have demonstrated that LHb-DBS elevates brain monoamine neurotransmitters. However, these changes do not account for the treatment efficacy on treatment-resistant depression, or the rapid behavioral effects in rats; the evidence suggests that altered synaptic potentiation may contribute to the treatment effects. We applied LHb-DBS in a rat model of learned helplessness (LH) and analyzed mammalian target of rapamycin (mTOR) phosphorylation...

Although there have been previous studies of deep-brain stimulation (DBS), we present, to our knowledge, the first example of high-frequency depressive severity measurement-based DBS treatment in particular and psychiatric treatment in general. Daily post-surgical e-mail prompts for a period of 6 months resulted in 93 administrations of a computerized adaptive test (CAT) of depression severity (CAT-Depression Inventory or CAT-DI) via the internet. There was an average of 3.37 weekly measurements with an average separation of 2...

Depression and anxiety are some of the most common comorbidities arising in patients with Parkinson's disease. However, their timely recognition and diagnosis are often hindered by overlap with other somatic features and a low rate of self-report. There is a need for greater awareness and for better assessment and treatment options are highly required. Currently available scales can serve as tools to monitor change over time and the effect of interventional strategies. Development of new therapeutic strategies, including nonpharmacological approaches such as transcranial magnetic stimulation and deep brain stimulation, may provide alternatives to currently available treatment approaches...

BACKGROUND: Electroconvulsive Therapy (ECT) and Deep Brain Stimulation (DBS) are effective treatments for patients with treatment-resistant depression (TRD). However, a common side effect of ECT is autobiographical memory loss (e.g., personal experiences), whereas the impact of DBS on autobiographical memories has never been established. OBJECTIVE: Comparing autobiographical memories following DBS and ECT. METHODS: In two hospitals in The Netherlands, we interviewed 25 TRD patients treated with DBS of the ventral anterior limb of the internal capsule (vALIC), 14 TRD patients treated with ECT and 22 healthy controls (HC) with the Autobiographical Memory Inventory - Short Form (AMI-SF) in a prospective, longitudinal study between March 2010 and August 2016...

The benefit of deep brain stimulation (DBS) in controlling the motor symptoms of Parkinson's disease is well established, however, the impact on the non-motor symptoms (NMS) remains to be elucidated, although the growing investigative efforts are promising. This article reviews the reported data and considers the level of evidence available with regard to the effect of DBS on NMS total burden and on the cognitive, neuropsychiatric, sleep, pain, dysautonomic, and weight domains. Multiple case series suggest that DBS improves the burden of NMS by reducing prevalence, intensity, and non-motor fluctuations...

BACKGROUND: Despite optimal medical treatment, including epilepsy surgery, many epilepsy patients have uncontrolled seizures. Since the 1970s interest has grown in invasive intracranial neurostimulation as a treatment for these patients. Intracranial stimulation includes both deep brain stimulation (DBS) (stimulation through depth electrodes) and cortical stimulation (subdural electrodes). This is an updated version of a previous Cochrane review published in 2014. OBJECTIVES: To assess the efficacy, safety and tolerability of DBS and cortical stimulation for refractory epilepsy based on randomized controlled trials (RCTs)...

BACKGROUND AND OBJECTIVE: The extent to which deep brain stimulation (DBS) can improve quality of life may be perceived as a permanent trade-off between neurological improvements and complications of therapy, comorbidities, and disease progression. PATIENTS AND METHODS: We retrospectively investigated 123 consecutive and non-preselected patients. Indications for DBS surgery were Parkinson's disease (82), dystonia (18), tremor of different etiology (21), Huntington's disease (1) and Gilles de la Tourette syndrome (1)...

Available data indicate that there are gender differences in many features of Parkinson's disease (PD). Precise identification of the gender differences is important to tailor treatment, predict outcomes, and meet other individual and social needs in women and men with PD. The aim of this study was to review the available clinical data on gender differences in PD. Original articles and meta-analyses published between 1990 and 2016 systematically exploring gender differences in PD were reviewed. There is slight male preponderance in incidence and prevalence of PD...

OBJECTIVE Deep brain stimulation (DBS) is effective in the management of patients with advanced Parkinson's disease (PD). While both the globus pallidus pars interna (GPi) and the subthalamic nucleus (STN) are accepted targets, their relative efficacy in randomized controlled trials (RCTs) has not been established beyond 12 months. The objective of this study was to conduct a meta-analysis of RCTs to compare outcomes among adults with PD undergoing DBS of GPi or STN at various time points, including 36 months of follow-up...

The current rationale for target selection in Tourette syndrome revolves around the notion of cortico-basal ganglia circuit involvement in the pathophysiology of the disease. However, despite extensive research, the ideal target for deep brain stimulation (DBS) is still under debate, with many structures being neglected and underexplored. Based on clinical observations and taking into account the prevailing hypotheses of network processing in Tourette syndrome, we chose the fields of Forel, namely field H1, as a target for DBS...

According to the World Health Organization, depression is one of the most common and most disabling psychiatric disorders, affecting at any given time approximately 325 million people worldwide. As there is strong evidence that depressive disorders are associated with a dynamic dysregulation of neural circuits involved in emotional processing, recently several attempts have been made to intervene directly in these circuits via deep brain stimulation (DBS) in patients with treatment-resistant major depressive disorder (MDD)...
