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...

Approximately 30% of individuals with epilepsy are refractory to antiepileptic drugs and currently approved neuromodulatory approaches fall short of providing seizure freedom for many individuals with limited utility for generalized seizures. Here, we expand on previous findings and investigate whether ventral pallidum deep brain stimulation (VP-DBS) can be efficacious for various acute seizure phenotypes. For rats administered pilocarpine, we found that VP-DBS (50 Hz) decreased generalized stage 4/5 seizure median frequency from 9 to 6 and total duration from 1667 to 264 s even after generalized seizures emerged...

Deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a method of neuromodulation used for refractory focal epilepsy. We report a patient suffering from drug-resistant epilepsy who developed novel visual symptoms and atypical seizures with the onset of ANT-DBS therapy. Rechallenge under video electroencephalography recording confirmed that lowering the stimulation voltage alleviated these symptoms. Subsequent stimulation with the initial voltage value did not cause the recurrence of either the visual symptoms or the new seizure type, and appeared to alleviate the patient's seizures in long-term follow-up...

PURPOSE OF REVIEW: Neurostimulation is becoming an increasingly accepted treatment alternative for patients with drug-resistant epilepsy (DRE) who are unsuitable surgery candidates. Standardized guidelines on when or how to use the various neurostimulation modalities are lacking. We conducted a systematic review on the currently available neurostimulation modalities primarily with regard to effectiveness and safety. RECENT FINDINGS: For vagus nerve stimulation (VNS), there is moderate-quality evidence for its effectiveness in adults with drug-resistant partial epilepsies...

BACKGROUND: Results of DBS of ATN in refractory epilepsy depend on accuracy of the electrode's location. We searched for characteristic intraoperative, intracerebral EEG recording pattern from anterior thalamic nuclei (ATNs) as a biological marker for verifying the electrode's position. METHODS: There were six patients with refractory epilepsy scheduled for deep brain stimulation (DBS) procedure. At surgery, to map the target, we recorded EEG from each lead of DBS electrodes...

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...

Cross-frequency phase-amplitude coupling (cfPAC) subserves an integral role in the hierarchical organization of inter-regional neuronal communication, and is also expressed by epileptogenic cortex during seizures. Here, we sought to characterize patterns of cfPAC expression in the anterior thalamic nuclei during seizures by studying extra-operative recordings in patients implanted with deep brain stimulation electrodes for intractable epilepsy. Nine seizures from 2 patients were analyzed in the peri-ictal period...

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...

BACKGROUND: Deep brain stimulation (DBS) is an important form of neuromodulation that is being applied to patients with motor, mood, or cognitive circuit disorders. Despite the efficacy and widespread use of DBS, the precise mechanisms by which it works remain unknown. Over the last decade, magnetoencephalography (MEG) has become an important functional neuroimaging technique used to study DBS. OBJECTIVE: This review summarizes the literature related to the use of MEG to characterize the effects of DBS...

Despite the use of first-choice anti-epileptic drugs and satisfactory seizure outcome rates after resective epilepsy surgery, a considerable percentage of patients do not become seizure free. ANT-DBS may provide for an alternative treatment option in these patients. This literature review discusses the rationale, mechanism of action, clinical efficacy, safety, and tolerability of ANT-DBS in drug-resistant epilepsy patients. A review using systematic methods of the available literature was performed using relevant databases including Medline, Embase, and the Cochrane Library pertaining to the different aspects ANT-DBS...

Lamotrigine (LTZ) is a phenyltriazine derivative which belongs to anti-epileptic drugs (AEDs) class and prescribed as mono- or adjunctive-therapy in treatment of epilepsy. Therapeutic drug monitoring (TDM) of AEDs provides a valid clinical tool in optimization of overall therapy. However, TDM is challenging due to the high biological samples (plasma/blood) storage/shipment costs and the limited availability of laboratories providing TDM services. Sampling in the form of dry plasma spot (DPS) or dry blood spot (DBS) are suitable alternative to overcome these issues...

The H fields of Forel constitute an intricate neuroanatomical structure that occupies a central position within the posterior subthalamus. Anatomically, it features a dense concentration of fiber bundles including corticofugal, pallidothalamic, cerebellothalamic and other projections that connect functionally relevant areas of the brain. Functionally, the fields of Forel are embedded within the cortico-striato-thalamo-cortical circuit and constitute the main link between the striatopallidal system and the thalamocortical network...

BACKGROUND: Idiopathic epilepsy is one of the most common neurological disorders in dogs. Unfortunately, up to 30% of dogs with idiopathic epilepsy show no improvement under antiepileptic drug treatment. Diffusion-weighted imaging is used in human medicine to identify epileptogenic foci in the brain to allow for more invasive treatments such as deep brain stimulation or surgical removal. The aim of this study was to ass the feasibility of interictal diffusion-weighted MRI in dogs and to evaluate the distribution of diffusion in the brains of dogs with idiopathic epilepsy (IE) and to compare these values to previously published values from healthy beagle dogs...

Very recently, neuromodulation through deep brain stimulation (DBS) has appeared as a new surgical procedure in the treatment of some types of dementia and epilepsy. The mammillothalamic and the mammillotegmental tracts are involved among the new targets. To our knowledge, a review article focused specifically on these mammillary body efferents is lacking in the medical literature. Their contribution to memory is, regrettably, often overlooked. There is evidence that mammillary bodies can contribute to memory independently from hippocampal formation, but the mechanism is not yet known...

Background: To report our experience of infections in deep brain stimulation (DBS) surgeries comparing shaving versus no shaving of cranial hair. Nonshaving is strongly preferred by patients due to aesthetic and psychological factors. Methods: This study is a prospective follow-up of the infection rate in 43 nonshaven DBS cases between April 2014 and December 2015 compared to our former infection rate with shaving in our center. Minimum follow-up was 6 months. All patients, except 7 epilepsy patients, received implantation of the electrodes together with the extension cables and internal pulse generator in one session...

OBJECTIVE: Deep brain stimulation (DBS) of the centromedian thalamic nucleus (CM) can be an alternative treatment option for intractable epilepsy patients. Since CM may be involved in widespread cortico-subcortical networks, identification of the cortical sub-networks specific to the target stimuli may provide further understanding on the underlying mechanisms of CM DBS. Several brain structures have distinguishing brain connections that may be related to the pivotal propagation and subsequent clinical effect of DBS...
