Mechanisms of deep brain stimulation: an intracellular study in rat thalamus. (1/725)

High-frequency deep brain stimulation (DBS) in the thalamus alleviates most kinds of tremor, yet its mechanism of action is unknown. Studies in subthalamic nucleus and other brain sites have emphasized non-synaptic factors. To explore the mechanism underlying thalamic DBS, we simulated DBS in vitro by applying high-frequency (125 Hz) electrical stimulation directly into the sensorimotor thalamus of adult rat brain slices. Intracellular recordings revealed two distinct types of membrane responses, both of which were initiated with a depolarization and rapid spike firing. However, type 1 responses repolarized quickly and returned to quiescent baseline during simulated DBS whereas type 2 responses maintained the level of membrane depolarization, with or without spike firing. Individual thalamic neurones exhibited either type 1 or type 2 response but not both. In all neurones tested, simulated DBS-evoked membrane depolarization was reversibly eliminated by tetrodotoxin, glutamate receptor antagonists, and the Ca(2+) channel antagonist Cd(2+). Simulated DBS also increased the excitability of thalamic cells in the presence of glutamate receptor blockade, although this non-synaptic effect induced no spontaneous firing such as that found in subthalamic nucleus neurones. Our data suggest that high-frequency stimulation when applied in the ventral thalamus can rapidly disrupt local synaptic function and neuronal firing thereby leading to a 'functional deafferentation' and/or 'functional inactivation'. These mechanisms, driven primarily by synaptic activation, help to explain the paradox that lesions, muscimol and DBS in thalamus all effectively stop tremor.  (+info)

Electron microscopy of tissue adherent to explanted electrodes in dystonia and Parkinson's disease. (2/725)

Deep brain stimulation (DBS) is used to treat a variety of severe medically intractable movement disorders, including Parkinson's disease, tremor and dystonia. There have been few studies examining the effect of chronic DBS on the brains of Parkinson's disease patients. Most of these post mortem studies concluded that chronic DBS caused mild gliosis around the lead track and did not damage brain tissue. There have been no similar histopathological studies on brains from dystonic patients who have undergone DBS. In this study, our objective was to discover whether tissue would be attached to DBS electrodes removed from patients for routine clinical reasons. We hoped that by examining explanted DBS electrodes using scanning (SEM) and/or transmission (TEM) electron microscopy we might visualize any attached tissue and thus understand the electrode-human brain tissue interaction more accurately. Initially, SEM was performed on one control DBS electrode that had not been implanted. Then 21 (one subthalamic nucleus and 20 globus pallidus internus) explanted DBS electrodes were prepared, after fixation in 3% glutaraldehyde, for SEM (n = 9) or TEM (n = 10), or both (n = 2), according to departmental protocol. The electrodes were sourced from two patients with Parkinson's disease, one with myoclonic dystonia, two with cervical dystonia and five with primary generalized dystonia, and had been in situ for 11 and 31 months (Parkinson's disease), 16 months (myoclonic dystonia), 14 and 24 months (cervical dystonia) and 3-24 months (primary generalized dystonia). Our results showed that a foreign body multinucleate giant cell-type reaction was present in all TEM samples and in SEM samples, prewashed to remove surface blood and fibrin, regardless of the diagnosis. Some of the giant cells were >100 microm in diameter and might have originated from either fusion of parenchymal microglia, resident perivascular macrophage precursors and/or monocytes/macrophages invading from the blood stream. The presence of mononuclear macrophages containing lysosomes and sometimes having conspicuous filopodia was detected by TEM. Both types of cell contained highly electron-dense inclusions, which probably represent phagocytosed material. Similar material, the exact nature of which is unknown, was also seen in the vicinity of these cells. This reaction was present irrespective of the duration of implantation and may be a response to the polyurethane component of the electrodes' surface coat. These findings may be relevant to our understanding of the time course of the clinical response to DBS in Parkinson's disease and various forms of dystonia, as well as contributing to the design characteristics of future DBS electrodes.  (+info)

Dorsal posterior parietal rTMS affects voluntary orienting of visuospatial attention. (3/725)

Patients with lesions in posterior parietal cortex (PPC) are relatively unimpaired in voluntarily directing visual attention to different spatial locations, while many neuroimaging studies in healthy subjects suggest dorsal PPC involvement in this function. We used an offline repetitive transcranial magnetic stimulation (rTMS) protocol to study this issue further. Ten healthy participants performed a cue-target paradigm. Cues prompted covert orienting of spatial attention under voluntary control to either a left or right visual field position. Targets were flashed subsequently at the cued or uncued location, or bilaterally. Following rTMS over right dorsal PPC, (i) the benefit for target detection at cued versus uncued positions was preserved irrespective of cueing direction (left- or rightward), but (ii) leftward cueing was associated with a global impairment in target detection, at all target locations. This reveals that leftward orienting was still possible after right dorsal PPC stimulation, albeit at an increased overall cost for target detection. In addition, rTMS (iii) impaired left, but (iv) enhanced right target detection after rightward cueing. The finding of a global drop in target detection during leftward orienting with a spared, relative detection benefit at the cued (left) location (i-ii) suggests that right dorsal PPC plays a subsidiary rather than pivotal role in voluntary spatial orienting. This finding reconciles seemingly conflicting results from patients and neuroimaging studies. The finding of attentional inhibition and enhancement occurring contra- and ipsilaterally to the stimulation site (iii-iv) supports the view that spatial attention bias can be selectively modulated through rTMS, which has proven useful to transiently reduce visual hemispatial neglect.  (+info)

Microstimulation of the superior colliculus focuses attention without moving the eyes. (4/725)

The superior colliculus (SC) is part of a network of brain areas that directs saccadic eye movements, overtly shifting both gaze and attention from position to position, in space. Here, we seek direct evidence that the SC also contributes to the control of covert spatial attention, a process that focuses attention on a region of space different from the point of gaze. While requiring monkeys to keep their gaze fixed, we tested whether microstimulation of a specific location in the SC spatial map would enhance visual performance at the corresponding region of space, a diagnostic measure of covert attention. We find that microstimulation improves performance in a spatially selective manner: thresholds decrease at the location in visual space represented by the stimulated SC site, but not at a control location in the opposite hemifield. Our data provide direct evidence that the SC contributes to the control of covert spatial attention.  (+info)

Different patterns of medication change after subthalamic or pallidal stimulation for Parkinson's disease: target related effect or selection bias? (5/725)

BACKGROUND: Bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) is favoured over bilateral globus pallidus internus (Gpi) DBS for symptomatic treatment of advanced Parkinson's disease (PD) due to the possibility of reducing medication, despite lack of definitive comparative evidence. OBJECTIVE: To analyse outcomes after one year of bilateral Gpi or STN DBS, with consideration of influence of selection bias on the pattern of postsurgical medication change. METHODS: The first patients to undergo bilateral Gpi (n = 10) or STN (n = 10) DBS at our centre were studied. They were assessed presurgically and one year after surgery (CAPIT protocol). RESULTS: Before surgery the Gpi DBS group had more dyskinesias and received lower doses of medication. At one year, mean reduction in UPDRS off medication score was 35% and 39% in the Gpi and STN groups, respectively (non-significant difference). Dyskinesias reduced in proportion to presurgical severity. The levodopa equivalent dose was significantly reduced only in the STN group (24%). This study high-lights the absence of significant differences between the groups in clinical scales and medication dose at one year. In the multivariate analysis of predictive factors for off-state motor improvement, the presurgical levodopa equivalent dose showed a direct relation in the STN and an inverse relation in the Gpi group. CONCLUSION: Differences in the patterns of medication change after Gpi and STN DBS may be partly due to a patient selection bias. Both procedures may be equally useful for different subgroups of patients with advanced PD, Gpi DBS especially for patients with lower threshold for dyskinesia.  (+info)

Subthalamic nucleus stimulation in tremor dominant parkinsonian patients with previous thalamic surgery. (6/725)

Before the introduction of high frequency stimulation of the subthalamic nucleus (STN), many disabled tremor dominant parkinsonian patients underwent lesioning or chronic electrical stimulation of the thalamus. We studied the effects of STN stimulation in patients with previous ventral intermediate nucleus (VIM) surgery whose motor state worsened. Fifteen parkinsonian patients were included in this study: nine with unilateral and two with bilateral VIM stimulation, three with unilateral thalamotomy, and one with both unilateral thalamotomy and contralateral VIM stimulation. The clinical evaluation consisted of a formal motor assessment using the Unified Parkinson's Disease Rating Scale (UPDRS) and neuropsychological tests encompassing a 50 point frontal scale, the Mattis Dementia Rating Scale, and the Beck Depression Inventory. The first surgical procedure was performed a mean (SD) of 8 (5) years after the onset of disease. STN implantation was carried out 10 (4) years later, and duration of follow up after beginning STN stimulation was 24 (20) months. The UPDRS motor score, tremor score, difficulties in performance of activities of daily living, and levodopa equivalent daily dose significantly decreased after STN stimulation. Neither axial symptoms nor neuropsychological status significantly worsened after the implantation of the STN electrodes. The parkinsonian motor state is greatly improved by bilateral STN stimulation even in patients with previous thalamic surgery, and STN stimulation is more effective than VIM stimulation in tremor dominant parkinsonian patients.  (+info)

Comparisons between pharmacologically and Edinger-Westphal-stimulated accommodation in rhesus monkeys. (7/725)

PURPOSE: Accommodation results in increased lens thickness and lens surface curvatures. Previous studies suggest that lens biometric accommodative changes are different with pharmacological and voluntary accommodation. In this study, refractive and biometric changes during Edinger-Westphal (EW) and pharmacologically stimulated accommodation in rhesus monkeys were compared. METHODS: Accommodation was stimulated by an indwelling permanent electrode in the EW nucleus of the midbrain in one eye each of four rhesus monkeys. Dynamic refractive changes were measured with infrared photorefraction, and lens biometric changes were measured with high-resolution, continuous A-scan ultrasonography for increasing stimulus current amplitudes, including supramaximal current amplitudes. Accommodation was then stimulated pharmacologically and biometry was measured continuously for 30 minutes. RESULTS: During EW-stimulated accommodation, lens surfaces move linearly with refraction, with an increase in lens thickness of 0.06 mm/D, an anterior movement of the anterior lens surface of 0.04 mm/D, and a posterior movement of the posterior lens surface of 0.02 mm/D. Peak velocity of accommodation (diopters per second) and lens thickness (in millimeters per second) increased with supramaximal stimulus currents, but without further increase in amplitude or total lens thickness. After carbachol stimulation, there was initially an anterior movement of the anterior lens surface and a posterior movement of the posterior lens surface; but by 30 minutes, there was an overall anterior shift of the lens. CONCLUSIONS: Ocular biometric changes differ with EW and pharmacological stimulation of accommodation. Pharmacological stimulation results in a greater increase in lens thickness, an overall forward movement of the lens and a greater change in dioptric power.  (+info)

Hypothalamic stimulation in chronic cluster headache: a pilot study of efficacy and mode of action. (8/725)

We enrolled six patients suffering from refractory chronic cluster headache in a pilot trial of neurostimulation of the ipsilateral ventroposterior hypothalamus using the stereotactic coordinates published previously. After the varying durations needed to determine optimal stimulation parameters and a mean follow-up of 14.5 months, the clinical outcome is excellent in three patients (two are pain-free; one has fewer than three attacks per month), but unsatisfactory in one patient, who only has had transient remissions. Mean voltage is 3.28 V, diplopia being the major factor limiting its increase. When the stimulator was switched off in one pain-free patient, attacks resumed after 3 months until it was turned on again. In one patient the implantation procedure had to be interrupted because of a panic attack with autonomic disturbances. Another patient died from an intracerebral haemorrhage that developed along the lead tract several hours after surgery; there were no other vascular changes on post-mortem examination. After 1 month, the hypothalamic stimulation induced resistance against the attack-triggering agent nitroglycerin and tended to increase pain thresholds at extracephalic, but not at cephalic, sites. It had no detectable effect on neurohypophyseal hormones or melatonin excretion. We conclude that hypothalamic stimulation has remarkable efficacy in most, but not all, patients with treatment-resistant chronic cluster headache. Its efficacy is not due to a simple analgesic effect or to hormonal changes. Intracerebral haemorrhage cannot be neglected in the risk evaluation of the procedure. Whether it might be more prevalent than in deep-brain stimulation for movement disorders remains to be determined.  (+info)

Pain is a frequently observed non-motor symptom of patients with Parkinsons disease. In some patients, Parkinsons-related pain responds to dopaminergic treatment. In the present study, we aimed to elucidate whether subthalamic deep brain stimulation has a similar beneficial effect on pain in Parkinsons disease, and whether this effect can be predicted by a pre-operative l-dopa challenge test assessing pain severity. We prospectively analyzed 14 consecutive Parkinsons patients with severe pain who underwent subthalamic deep brain stimulation. In 8 of these patients, pain severity decreased markedly with high doses of l-dopa, irrespective of the type and localization of the pain symptoms. In these patients, subthalamic deep brain stimulation provided an even higher reduction of pain severity than did dopaminergic treatment, and the majority of this group was pain-free after surgery. This effect lasted for up to 41 months. In the remaining 6 patients, pain was not improved by dopaminergic ...
The Seizure and Cognitive Outcome of Anterior Thalamic Nucleus Deep Brain Stimulation for Patients with Intractable Epilepsy, Yuguang Guan, Sichang Chen, Yao Zhang, Changqing Liu,
Deep brain stimulation (DBS) has been shown to be clinically effective for some forms of treatment-resistant chronic pain, but the precise mechanisms of action are not well understood. Here, we present an analysis of magnetoencephalography (MEG) data from a patient with whole-body chronic pain, in order to investigate changes in neural activity induced by DBS for pain relief over both short- and long-term. This patient is one of the few cases treated using DBS of the anterior cingulate cortex (ACC). We demonstrate that a novel method, null-beamforming, can be used to localise accurately brain activity despite the artefacts caused by the presence of DBS electrodes and stimulus pulses. The accuracy of our source localisation was verified by correlating the predicted DBS electrode positions with their actual positions. Using this beamforming method, we examined changes in whole-brain activity comparing pain relief achieved with deep brain stimulation (DBS ON) and compared with pain experienced with no

Deep brain stimulation may have a beneficial effect on driving ability for people with Parkinsons disease, according to a new study published in the December 18, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Deep brain stimulation uses a surgical implant similar to a pacemaker to send electrical impulses to the brain.. Up until now, we werent sure how deep brain stimulation would affect driving, said study author Carsten Buhmann, MD, of University Medical Center Hamburg-Eppendorf in Hamburg, Germany. On the one hand, it might enhance driving ability by improving the motor problems which occur with Parkinsons disease, but on the other hand, it might hamper driving because it potentially causes a decline in executive cognitive skills.. The study involved 23 people who had deep brain stimulators, 21 people with Parkinsons disease who did not have stimulators and 21 people who did not have Parkinsons disease. All of the participants had been ...
Results Comparison of the two DBS targets revealed few significant group differences. STN DBS was associated with greater mean reductions on some measures of processing speed, only one of which was statistically significant in comparison with stimulation of GPi. GPi DBS was associated with lower mean performance on one measure of learning and memory that requires mental control and cognitive flexibility. Compared to the group receiving BMT, the combined DBS group had significantly greater mean reductions at 6-month follow-up in performance on multiple measures of processing speed and working memory. After calculating thresholds for statistically reliable change from data obtained from the BMT group, the combined DBS group also displayed higher rates of decline in neuropsychological test performance. Among study completers, 18 (11%) study participants receiving DBS displayed reliable decline by multiple indicators in two or more cognitive domains, a significantly higher rate than in the BMT group ...

Deep brain stimulation of the globus pallidus internus alleviates involuntary movements in patients with dystonia. However, the mechanism is still not entirely understood. One hypothesis is that deep brain stimulation suppresses abnormally enhanced synchronized oscillatory activity within the motor cortico-basal ganglia network. Here, we explore deep brain stimulation-induced modulation of pathological low frequency (4-12 Hz) pallidal activity that has been described in local field potential recordings in patients with dystonia. Therefore, local field potentials were recorded from 16 hemispheres in 12 patients undergoing deep brain stimulation for severe dystonia using a specially designed amplifier allowing simultaneous high frequency stimulation at therapeutic parameter settings and local field potential recordings. For coherence analysis electroencephalographic activity (EEG) over motor areas and electromyographic activity (EMG) from affected neck muscles were recorded before and immediately after
Parkinsons Disease is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies related to the epidemiology, etiology, pathogenesis, genetics, cellular, molecular and neurophysiology, as well as the diagnosis and treatment of Parkinsons disease.
During the last 25 years, more than 100,000 patients have been treated with Deep Brain Stimulation (DBS). While human clinical and animal preclinical research has shed light on the complex brain-signaling disturbances that underpin e.g., Parkinsons disease (PD), less information is available when it comes to complex psychosocial changes following DBS interventions. In this contribution, we propose to more thoroughly investigate complex personality-related changes following deep brain stimulation through refined and reliable instruments in order to help patients and their relatives in the post-surgery phase. By pursuing this goal, we first outline the clinical importance DBS has attained followed by discussing problematic and undesired non-motor problems that accompany some DBS interventions. After providing a brief definition of complex changes, we move on by outlining the measurement problem complex changes relating to non-motor symptoms currently are associated with. The latter circumstance

Mandybur and Revilla are members of the James J. and Joan A. Gardner Center for Parkinsons Disease and Movement Disorders at the UC Neuroscience Institute, a specialty center within UC Health. Principal investigator of the study was Michael Okun, MD, a neurologist and co-director of the Center for Movement Disorders and Neurorestoration at the University of Florida College of Medicine. Deep brain stimulation (DBS) devices stimulate the subthalamic nucleus deep within the brain. Deep brain stimulation surgery has been shown to reduce symptoms of Parkinsons and to improve quality of life. The Lancet Neurology study examined the new Libra and LibraXP ...
Deep brain stimulation may have benefits beyond the treatment of brain disorders - it may provide an alternative therapy for people with high blood pressure patients who arent able to treat their condition with drugs, according to a new study.. The report describes the case of a 55-year-old man who underwent deep brain stimulation - which uses a surgically implanted device to send electrical pulses into the brain - as treatment for chronic pain. The man also had high blood pressure, or hypertension , which had stayed elevated despite previous treatments, including being medicated with four prescription drugs simultaneously.. Though the deep brain stimulation did little to treat the patients pain, it lowered his blood pressure enough for him to quit taking his blood pressure medications for nearly three years, the researchers said.. While the findings are preliminary, and require validation in a larger number of patients, they are exciting, said William T. Abraham, director of the division of ...
Deep brain stimulation involves using a pacemaker-like device to deliver constant electrical stimulation to problematic areas within the brain. It has been used to treat over 40,000 people with Parkinsons disease and essential tremor worldwide and is currently undergoing clinical trials as a treatment for depression and obsessive-compulsive disorder. This article will provide an historical account of deep brain stimulation in order to illustrate the plurality of interests involved in the development and stabilization of deep brain stimulation technology. Using Latours notion of immutable mobiles, this article will illustrate the importance of clinical assessment tools in shaping technological development in the era of medical device regulation. Given that such tools can serve commercial and professional interests, this article suggests that it is necessary to scrutinise their application in research contexts to ensure that they capture clinical changes that are meaningful for patients and ...

BACKGROUND: Accuracy of electrode placement is an important determinant of outcome following deep brain stimulation (DBS) surgery. Data on accuracy of electrode placement into the globus pallidum interna (GPi) in paediatric patients is limited, particularly those with non-primary dystonia who often have smaller GPi. Pallidal DBS is known to be more effective in the treatment of primary dystonia compared with secondary dystonia.
Deep brain stimulation (DBS) is the technique of neurostimulation of deep brain structures for the treatment of conditions such as essential tremor, dystonia, Parkinsons disease and chronic pain syndromes. The procedure uses implanted deep brain stimulation electrodes connected to extension leads and an implantable pulse generator (IPG). Hardware failure related to the DBS procedure is not infrequent, and includes electrode migration and disconnection. We describe a patient who received bilateral globus pallidus internus DBS for dystonia with initially good clinical response, but the device eventually failed. Radiographs showed multiple twisting of the extension leads with disconnection from the brain electrodes and a diagnosis of Twiddlers syndrome was made. Twiddlers syndrome was first described in patients with cardiac pacemakers. Patients with mental disability, elderly and obese patients are at increased risk. Twiddlers syndrome should be suspected whenever there is a failure of the DBS device
Deep brain stimulation provides benefits for people with Parkinson disease by managing some of their complications. None of the few reports in the current literature establishes the functionality of deep brain stimulation when activated during phacoemulsification.A 70-year-old woman with subthalamic deep brain stimulator (DBS) for advanced Parkinson disease was referred to our center for cataract surgery. To evaluate any possible interference between ultrasounds and the DBS, we registered the impedance of the electrodes before and after surgery.The patient underwent uneventful phacoemulsification of her right eye under topical anesthesia with her internal pulse generator device activated. During the surgical procedure, all potential variations of the impedance of the electrodes were recorded.This report demonstrates that phacoemulsification under topical anesthesia is a feasible procedure in patients with DBS, showing no interference between the ultrasounds and the internal pulse ...

Deep brain stimulation (DBS) is associated with significant improvement of motor complications in patients with severe Parkinsons disease after some 6-12 months of treatment.. Long-term results in a large number of patients have been reported only from a single study centre. We report 69 Parkinsons disease patients treated with bilateral DBS of the subthalamic nucleus (STN, n = 49) or globus pallidus internus (GPi, n = 20) included in a multicentre study.. Patients were assessed preoperatively and at 1 year and 3-4 years after surgery. The primary outcome measure was the change in the off medication score of the Unified Parkinsons Disease Rating Scale motor part (UPDRS-III) at 3-4 years. Stimulation of the STN or GPi induced a significant improvement (50 and 39%; P , 0.0001) of the off medication UPDRS-III score at 3-4 years with respect to baseline. Stimulation improved cardinal features and activities of daily living (ADL) (P , 0.0001 and P , 0.02 for STN and GPi, respectively) and ...

By Daniel Albaugh. One of my most fascinating experiences as a doctoral student of neuroscience began with an early morning trip to the university hospital. Upon arrival, my laboratory colleagues and I met with one of the clinical neurologists, who introduced us to a patient suffering from advanced Parkinsons Disease. Medications were no longer working effectively, and the patients motor symptoms were severe and debilitating. The day that we arrived, the patient was to have electrodes implanted deep into the brain circuitry that was misbehaving in his disease, the first step in a revolutionary therapeutic approach known as deep brain stimulation (DBS).. What is Deep Brain Stimulation?. DBS is an increasingly well-utilized therapeutic tool for many neurological diseases, predominantly movement disorders. With this therapy, high frequency electrical stimulation is chronically delivered to a target brain region, powered by a battery source implanted near the patients clavicle. In Parkinsons ...
CINCINNATI - For more than 15 years deep brain stimulation (DBS) surgery has been an important treatment option for people with Parkinsons disease, a disorder of the nervous system caused by a lack of dopamine in the brain. Although the treatment is approved by the FDA for patients who no longer respond to medication and who typically have suffered symptoms of the disease for 10 or more years, a new European study published this month in the New England Journal of Medicine is causing doctors to ask whether the procedure should be offered earlier in the disease process.
Purpose: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been the mainstream surgical procedure for advanced Parkinsons disease (PD) during the last decade. Reports from a few individual centres have hinted that women who receive STN DBS are under-represented. We aimed to evaluate the gender distribution of patients with PD who had received STN DBS during the last ten years, and to discuss the findings in relation to studies on gender prevalence of PD.. Methods: A search of the PubMed database of clinical papers in English language related to STN DBS between 2000 and 2009 was conducted. Care was taken to minimize redundancies in reporting of published patients. The proportion of men and women were expressed in total and according to pre-defined geographic regions.. Results: One hundred and thirty five papers were eligible for review. The gender of the patients was specified in 119 papers on a total of 3880 patients, of which 63% were men. According to geographic origin of ...

Introduction Deep brain stimulation (DBS) is a common neurosurgical procedure for relieving movement related disorders such as Parkinsons disease. DBS extends uncertainties associated with suboptimal target selection. Our aim was to evaluate the feasibility to objectively assess clinical effects obtained during intraoperative test stimulation based on acceleration measurements of the neurologists wrist. Methods One patient referred for bilateral DBS-implantation for the treatment of Parkinsons disease was included in the study. A 3-axis accelerometer was fixed on the neurologists wrist during intraoperative test stimulation. While the intensity of electric current used for stimulation was increased , the neurologist continuously moved the patients wrist to determine the moment of and the amplitude at rigidity release (stimulation threshold). For each test stimulation position, differrent mathematical features were determined and statistically compared a) for the time period
BACKGROUND: Innovative neurosurgical treatments present a number of known risks, the natures and probabilities of which can be adequately communicated to patients via the standard procedures governing obtaining informed consent. However, due to their novelty, these treatments also come with unknown risks, which require an augmented approach to obtaining informed consent. OBJECTIVE: This paper aims to discuss and provide concrete procedural guidance on the ethical issues raised by serious unexpected complications of novel deep brain stimulation treatments. APPROACH: We illustrate our analysis using a case study of the unexpected development of recurrent stereotyped events in patients following the use of deep brain stimulation (DBS) to treat severe chronic pain. Examining these unexpected complications in light of medical ethical principles, we argue that serious complications of novel DBS treatments do not necessarily make it unethical to offer the intervention to eligible patients. However, the

BACKGROUND: Deep brain stimulation (DBS) is a well-established treatment to reduce tremor, notably in Parkinson disease. DBS may also be effective in post-traumatic tremor, one of the most common movement disorders caused by head injury. However, the cohorts of patients often have multiple lesions that may impact the outcome depending on which fiber tracts are affected. CASE DESCRIPTION: A 20-year-old man presented after road traffic accident with severe closed head injury and polytrauma. Computed tomography scan showed left frontal and basal ganglia hemorrhagic contusions and intraventricular hemorrhage. A disabling tremor evolved in step with motor recovery. Despite high-intensity signals in the intended thalamic target, a visual analysis of the preoperative diffusion tensor imaging revealed preservation of connectivity of the intended target, ventralis oralis posterior thalamic nucleus (VOP). This was confirmed by the postoperative tractography study presented here. DBS of the VOP/zona incerta was
Bilateral subthalamic nucleus deep brain stimulation for Parkinsons disease improves limb function. Unpublished observations from our clinic noted that some subthalamic nucleus deep brain stimulation patients complain of post-operative dyspnea. Therefore, we designed a prospective, longitudinal study to characterize this in greater depth. We used specific questionnaires to assess dyspnea in patients with electrodes in the subthalamic nucleus (n=13) or ventral intermediate thalamus (n=7). St. Georges Hospital Respiratory Questionnaire symptom subscale scores were greater in subthalamic nucleus patients (median=18.60, interquartile range=40.80) than ventral intermediate thalamus patients (median = 0.00, interquartile range=15.38) at greater than 6 months post-operatively (p|0.05). Several of the subthalamic nucleus patients exhibited functional impairments as judged by the St. Georges Hospital Respiratory Questionnaire impact subscale, the Medical Research Council Dyspnoea Scale, and the Dyspnoea-12
Bilateral subthalamic nucleus deep brain stimulation for Parkinsons disease improves limb function. Unpublished observations from our clinic noted that some subthalamic nucleus deep brain stimulation patients complain of post-operative dyspnea. Therefore, we designed a prospective, longitudinal study to characterize this in greater depth. We used specific questionnaires to assess dyspnea in patients with electrodes in the subthalamic nucleus (n=13) or ventral intermediate thalamus (n=7). St. Georges Hospital Respiratory Questionnaire symptom subscale scores were greater in subthalamic nucleus patients (median=18.60, interquartile range=40.80) than ventral intermediate thalamus patients (median = 0.00, interquartile range=15.38) at greater than 6 months post-operatively (p|0.05).

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, Tourettes syndrome, presenile dementia, anorexia nervosa and other refractory mental illnesses. Many encouraging results have been reported. The aim of the present review was to briefly describe the mechanisms, target selection, side effects, ethical arguments and risks associated with deep brain stimulation. Although deep brain stimulation is a developing and promising treatment, a large amount of research is still required to determine its curative effect, and the selection of ...
A 31-year-old Chinese man with intractable severe, lifelong Tourettes syndrome characterised by forceful self-injurious motor tics and socially embarrassing vocal tics was treated with bilateral deep brain stimulation. Electrodes were implanted into the thalamic targets at the centromedian-parafascicular complex according to Hasslers nomenclature. A dramatic reduction of tics resulted. At 18 months postoperatively, there was an 81% improvement in his total tics count and a 58% improvement in his Yale Global Tic Severity Scale. His modified Rush video scale decreased from 13 to 8 and visual analogue scale from 10 to 3. These data show that bilateral deep brain stimulation of the thalamus can have a favourable immediate effect on severe tics in a selected group of adult patients suffering from intractable Tourettes syndrome and postoperatively the beneficial effects persisted for at least 18 months ...
Subthalamic nucleus deep brain stimulation (STN DBS) protects dopaminergic neurons of the substantia nigra pars compacta (SNpc) against 6-OHDA and MPTP. We evaluated STN DBS in a parkinsonian model that displays α-synuclein pathology using unilateral, intranigral injections of recombinant adeno-associated virus pseudotype 2/5 to overexpress wildtype human α-synuclein (rAAV2/5 α-syn). A low titer of rAAV2/5 α-syn results in progressive forelimb asymmetry, loss of striatal dopaminergic terminal density and modest loss of SNpc dopamine neurons after eight weeks, corresponding to robust human-Snca expression and no effect on rat-Snca, Th, Bdnf or Trk2 ...
Within the past few years, there has been a renaissance of functional neurosurgery for the treatment of dystonic movement disorders. In particular, deep brain stimulation (DBS) has widened the spectrum of therapeutical options for patients with otherwise intractable dystonia. It has been introduced only with a delay after DBS became an accepted treatment for advanced Parkinson disease (PD). In this overview, the authors summarize the current status of its clinical application in dystonia. Deep brain stimulation for dystonia has been developed from radiofrequency lesioning, but it has replaced the latter largely in most centers. The main target used for primary dystonia is the posteroventral globus pallidus internus (GPi), and its efficacy has been shown in generalized dystonia, segmental dystonia, and complex cervical dystonia. The optimal target for secondary dystonias is still unclear, but some patients appear to benefit more from thalamic stimulation. The improvement of dystonia with chronic DBS

In the current era of functional surgery for movement disorders, deep brain stimulation (DBS) of the globus pallidus internus (GPi) is emerging as the favoured intervention for patients with dystonia. Here we report our results in 20 patients with medically intractable dystonia treated with GPi stimulation. The series comprised 14 patients with generalized dystonia and six with spasmodic torticollis. Although comparisons were limited by differences in their respective neurological rating scales, chronic DBS clearly benefited both patient groups. Data conveying the rate of change in neurological function following intervention are also presented, demonstrating the gradual but progressive and sustained nature of improvement following stimulation of the GPi in dystonic patients.
Deep brain stimulation (DBS) in the thalamic ventrointermediate nucleus (VIM) is the traditional target for the surgical treatment of pharmacologically refractory essential tremor or parkinsonian tremor. Studies in recent years on DBS in posterior subthalamic area (PSA), including the zona incerta and the prelemniscal radiation, have shown promising results in tremor suppression, particularly for those tremors difficult to be well controlled by VIM DBS, such as the proximal postural tremor, distal intention tremor and some cerebellar outflow tremor in various diseases including essential tremor and multiple sclerosis. The adverse effect profile of the PSA DBS is mild and transient, without lasting or striking dysarthria, disequilibrium or tolerance, in contrast to VIM DBS, particularly bilateral DBS. However, the studies on PSA DBS so far are still limited, with a handful of studies on bilateral PSA, and a short follow up duration compared to VIM. More studies are needed for direct comparison of these
Cluster headache is a severely debilitating disorder that can remain unrelieved by current pharmacotherapy. Alongside ablative neurosurgical procedures, neuromodulatory treatments of deep brain stimulation (DBS) and occipital nerve simulation have emerged in the last few years as effective treatments for medically refractory cluster headaches. Pioneers in the field have sought to publish guidelines for neurosurgical treatment; however, only small case series with limited long-term follow-up have been published. Controversy remains over which surgical treatments are best and in which circumstances to intervene. Here we review current data on neurosurgical interventions for chronic cluster headache focusing upon DBS and occipital nerve stimulation, and discuss the indications for and putative mechanisms of DBS including translational insights from functional neuroimaging, diffusion weighted tractography, magnetoencephalography and invasive neurophysiology.
To provide deep brain stimulation therapy to alter pathological functioning of circuitry involved in causing medically-resistant obsessive-compulsive disorder.
BACKGROUND: There is solid evidence of the long term efficacy of deep brain stimulation of the globus pallidus pars interna in the treatment of generalised dystonia. However there are conflicting reports concerning whether certain subgroups gain more benefit from treatment than others. We analysed the results of a series of 60 cases to evaluate the effects of previously proposed prognostic factors including dystonia aetiology, dystonia phenotype, age at onset of dystonia, and duration of dystonia prior to treatment.

A Leksell Stereotactic frame was mounted on the patients head. An O-arm® was used to perform a stereotactic volumetric computed tomography (CT) scan of the head. These CT images were then merged with a Stealth navigation system protocol MRI of the brain. A three-dimensional reconstruction of the images was performed to identify the locations of the anterior commissure (AC) and posterior commissure (PC). The coordinates chosen were 12 mm to the left and right of the AC-PC midpoint, 3 mm behind the AC-PC midpoint, and 4 mm below the AC-PC midpoint. The AC-PC distance was measured to be 26.87 mm. After a bifrontal incision, bilateral burr holes overlying the coronal suture were created approximately 4 cm from the midline at each side. Next, a microelectrode drive for the right side was mounted to the Leksell frame. Microelectrode recordings (MERs) were not optimal for the right side, so an O-arm CT scan was performed which showed that the electrodes were lateral and anterior to the desired ...
Objective: One patient received oral levodopa during a study aiming for better understanding of the basal ganglia and of the mechanisms of deep brain stimulation of the subthalamic nucleus (STN DBS) with and without intravenous (IV) levodopa infusion in patients with Parkinsons disease (PD). The results from oral and IV levodopa treatment are presented. Methods: Five patients with advanced PD were included in the original study. During planned STN DBS surgery microdialysis probes were implanted in the right putamen and in the right and left globus pallidus interna (Gpi). During the study, microdialysis was performed continuously and STN DBS, with and without IV levodopa infusion, was performed according to a specific protocol. After DBS surgery, but before STN DBS was started, one patient received oral levodopa/ benserazide and entacapone tablets out of protocol due to distressing parkinsonism. Results: The levodopa levels increased prompt in the central nervous system after the first PD medication
A clinical and scientific focus is the identification and clinical testing of new target points for neuromodulatory therapeutic procedures such as deep brain stimulation. In addition to implementing these new procedures for the treatment of neuropsychiatric disorders, both struct ural imaging by high field-MRI and PET and the acquisition of functional and cognitive neuro-behavioral parameters by Near-Infrared Spect roscopy and Event-related Potentials are used to perform scientific evaluations. In particular, the behavioral effect s of deep brain stimulation as a function of the target and parameters of the stimulation are examined. Investigations of the clinical effect s of deep brain stimulation in atypical Parkinson syndromes (PSP, MSA) and substance dependence are conduct ed in collaboration with colleagues in psychiatry. For example, we have shown in patients with PSP that stimulation of the pedunculopontine nuclei reduces the spontaneous tendency to fall, and that high frequency ...
Substance use disorders (SUDs) are a growing public health concern with only a limited number of approved treatments. However, even approved treatments are subject to limited efficacy with high long-term relapse rates. Current treatment approaches are typically a combination of pharmacotherapies and behavioral counselling. Growing evidence and technological advances suggest the potential of brain stimulation techniques for the treatment of SUDs. There are three main brain stimulation techniques that are outlined in this review: transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and deep brain stimulation (DBS). The insula, a region of the cerebral cortex, is known to be involved in critical aspects underlying SUDs, such as interoception, decision making, anxiety, pain perception, cognition, mood, threat recognition, and conscious urges. This review focuses on both the preclinical and clinical evidence demonstrating the role of the insula in addiction, thereby

Abnormally sustained beta-frequency synchronisation between the motor cortex and subthalamic nucleus (STN) is associated with motor symptoms in Parkinsons disease (PD). It is currently unclear whether STN neurons have a preference for beta-frequency input (12-35 Hz), rather than cortical input at other frequencies, and how such a preference would arise following dopamine depletion. To address this question, we combined analysis of cortical and STN recordings from awake human PD patients undergoing deep brain stimulation surgery with recordings of identified STN neurons in anaesthetised rats. In these patients, we demonstrate that a subset of putative STN neurons is strongly and selectively sensitive to magnitude fluctuations of cortical beta oscillations over time, linearly increasing their phase-locking strength with respect to the full range of instantaneous amplitude in the beta-frequency range. In rats, we probed the frequency response of STN neurons in the cortico-basal-ganglia-network ...
We investigate the brain networks and neurotransmitters involved in symptoms of movement disorders, such as Parkinsons disease, and the mechanisms by which modulating these networks through electrical stimulation affects these symptoms. We are particularly interested in the mechanisms through which neuromodulation therapies like deep brain stimulation affect non-motor brain functions, such as cognitive function and mood. We use imaging of specific neurotransmitters, such as acetylcholine and dopamine, to understand the changes in brain chemistry associated with the clinical effects of deep brain stimulation and to predict which patients are likely to have changes in non-motor symptoms following DBS. Through collaborations with our neurosurgery colleagues, we explore brain function by making recordings during DBS surgery during motor and non-motor tasks.

Deep brain stimulation works by implanting fine wires (electrodes) into a specific portion of the brain. This was originally known as thalamic DBS or Vim stim, and initially targeted the thalamus, which is a major relay station deep within the brain. In recent years, many surgeons have been using another area, the posterior subthalamic area (PSA) as the target for deep brain stimulation in essential tremor. Our experience with DBS in the PSA has been extremely encouraging and this is now our preferred target.. ...

AIM: To evaluate the results of ventral intermediate (Vim) thalamic deep brain stimulation (DBS) in patients with tremor predominant Parkinsons disease (PD) at 6 years post surgery.. METHODS: This was a prolonged follow-up study of 38 patients from eight centres who participated in a multicentre study, the 1 year results of which have been published previously. Total scores as well as scores for individual items of the motor part and the disability part of the Unified Parkinsons Disease Rating Scale were used for evaluation.. RESULTS: Tremor was still effectively controlled by DBS and appendicular rigidity and akinesia remained stable compared with baseline. Axial scores (speech, gait and postural instability), however, worsened, and in parallel the initial improvement in activities of daily living scores at the 1 year follow-up had disappeared at 6 years, despite sustained improvement of tremor. Remarkably, neither daily doses of dopaminergic medication nor fluctuations and dyskinesias had ...
She also explained that the two of them first need to prepare a paper for publication that summarizes the current facts about the use of DBS to treat RLS. Once that is published, then they can request grant funding for a research project. She had mentioned that she knew that her co-investigator also had potential candidates. What I heard today is that she does not know whether these others are pure RLS patients (like me) or whether they are Parkinsons patients who also have RLS. If it is the latter, then it may increase my chances of being picked since research studies like simple, unambiguous results and not something where others can criticized that the DBS fixed the Parkinsons, so the RLS simply went away. Of course, there is also the argument that DBS is an established treatment for Parkinsons, so the risk to the patient would be lower ...
