Determinants of Functional Independence or Its Loss following Subthalamic Nucleus Stimulation in Parkinson's Disease.

This study aimed to describe the change in functional status following bilateral subthalamic nucleus stimulation (STN-DBS) in Parkinson's disease (PD) and to identify predictors of postoperative functional dependence.

Cortico-basal white matter alterations occurring in Parkinson's disease.

Magnetic resonance imaging studies typically use standard anatomical atlases for identification and analyses of (patho-)physiological effects on specific brain areas; these atlases often fail to incorporate neuroanatomical alterations that may occur with both age and disease. The present study utilizes Parkinson's disease and age-specific anatomical atlases of the subthalamic nucleus for diffusion tractography, assessing tracts that run between the subthalamic nucleus and a-priori defined cortical areas kno...

Postural instability and gait disorders after subthalamic nucleus deep brain stimulation in Parkinson's disease: a PET study.

Patients with Parkinson's disease sometimes report postural instability and gait disorders (PIGD) after subthalamic nucleus deep brain stimulation (STN-DBS). Whether this is the direct consequence of DBS or the result of natural disease progression is still subject to debate.

Long-term effects of bilateral subthalamic nucleus stimulation on sleep in patients with Parkinson's disease.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been reported to have a positive effect on sleep-wake disturbance in Parkinson's disease (PD). We aimed to investigate the long-term effects of STN DBS on sleep in patients with PD.

Automated and objective measures of gait dynamics in camptocormia Parkinson's Disease subthalamic deep brain stimulation.

Axial motor features are common in Parkinson's disease (PD). These include gait impairment and postural abnormalities, such as camptocormia. The response of these symptoms to deep brain stimulation (DBS) is variable and difficult to assess objectively. For the first time, this study analyzes the treatment outcomes of two PD patients with camptocormia that underwent bilateral subthalamic nucleus (STN)-DBS evaluated with disruptive technologies.

Impact of subthalamic nucleus stimulation did not differ on young-onset and older-onset Parkinson's disease: a three-year follow up.

To assess the role of onset age in the results of bilateral subthalamic nucleus deep brain stimulation (STN-DBS), we carried out a retrospective study of two groups of patients regarding age at disease onset.

Comparison of Subthalamic Nucleus and Globus Pallidus Internus Deep Brain Stimulation Surgery on Parkinson's Disease-related Pain.

This study was to analyze and compare the effects of subthalamic nucleus (STN)-Deep brain stimulation (DBS) and Globus pallidus internus (GPi)-DBS on Parkinson's disease (PD)-related pain.

Non-motor outcomes depend on location of neurostimulation in Parkinson's disease.

Deep brain stimulation of the subthalamic nucleus is an effective and established therapy for patients with advanced Parkinson's disease improving quality of life, motor symptoms and non-motor symptoms. However, there is a considerable degree of interindividual variability for these outcomes, likely due to variability in electrode placement and stimulation settings. Here, we present probabilistic mapping data from a prospective, open-label, multicentre, international study to investigate the influence of th...

Hitting the brakes: pathological subthalamic nucleus activity in Parkinson's disease gait freezing.

Gait freezing is a complex and devastating paroxysmal motor arrest commonly suffered in Parkinson's disease that causes significant impairment to mobility, commonly resulting in falls and subsequent injury. The neurobiological basis of gait freezing in Parkinson's disease is poorly understood and thus, currently available therapies are partially effective at best. We used a validated virtual reality gait paradigm to elicit freezing behaviour intraoperatively in eight patients undergoing subthalamic nucleus ...

Update on diagnostics and therapy of idiopathic Parkinson's disease.

At least 300,000 people with idiopathic Parkinson's disease are living in Germany. Due to the demographic change the number of affected patients is expected to increase continuously. This article presents the evidence-based diagnostics and therapy of idiopathic Parkinson's disease. It provides an overview especially on new findings and developments in recent years.

Interleaved deep brain stimulation for dyskinesia management in Parkinson's disease.

In patients with Parkinson's disease, stimulation above the subthalamic nucleus (STN) may engage the pallidofugal fibers and directly suppress dyskinesia.

Predictive potential of preoperative electroencephalogram for neuropsychological change following subthalamic nucleus deep brain stimulation in Parkinson's disease.

Deep brain stimulation of the bilateral subthalamic nucleus (STN-DBS) improves motor fluctuation and severe dyskinesia in advanced Parkinson's disease (PD). Effects on non-motor symptoms, such as neurocognitive side effects, can also influence the quality of life of both patients with PD and caregivers. Predictive quantitative factors associated with postoperative neurocognitive deterioration therefore warrant further attention. Here, we evaluated preoperative electroencephalogram (EEG) as a predictive mark...

Deep brain stimulation for Parkinson's disease modulates high-frequency evoked and spontaneous neural activity.

Deep brain stimulation is an established therapy for Parkinson's disease; however, its effectiveness is hindered by limited understanding of therapeutic mechanisms and the lack of a robust feedback signal for tailoring stimulation. We recently reported that subthalamic nucleus deep brain stimulation evokes a neural response resembling a decaying high-frequency (200-500 Hz) oscillation that typically has a duration of at least 10 ms and is localizable to the dorsal sub-region. As the morphology of this r...

Freezing of gait in Parkinson's disease reflects a sudden derangement of locomotor network dynamics.

Freezing of gait is a disabling symptom of Parkinson's disease that causes a paroxysmal inability to generate effective stepping. The underlying pathophysiology has recently migrated towards a dysfunctional supraspinal locomotor network, but the actual network derangements during ongoing gait freezing are unknown. We investigated the communication between the cortex and the subthalamic nucleus, two main nodes of the locomotor network, in seven freely-moving subjects with Parkinson's disease with a novel dee...

Stimulation challenge test after STN DBS improves satisfaction in Parkinson's disease patients.

Although subthalamic Deep Brain Stimulation (STN DBS) is proven effective in improving symptoms of Parkinson's Disease (PD), previous literature demonstrates a discrepancy between objective improvement and patients' perception thereof. We aimed to examine whether postoperative stimulation challenge tests (SCT) alters patients' satisfaction after STN DBS for PD.

Parkinson Disease.

Parkinson disease is a common neurodegenerative disorder that affects millions of people worldwide. Important advances in the treatment, etiology, and the pathogenesis of Parkinson disease have been made in the past 50 years. This article provides a review of the current understanding of Parkinson disease, including the epidemiology, phenomenology, and treatment options of the disease.

The Mini-BESTest is an independent predictor of falls in Parkinson Disease.

Falls in Parkinson Disease are a complex health problem, with multidimensional causes and consequences.

Traditional trial-and-error versus neuroanatomical-3D-image software-assisted deep brain stimulation programming in patients with Parkinson's disease.

Programming Deep Brain Stimulation (DBS) settings in patients with Parkinson's disease (PD) is challenging and time consuming due to the vast number of possible parameter combinations. This results in long sessions that can be exhausting for the patients and the physicians. GUIDE (Boston Scientific) is a 3D-neuroantomical visual software that precisely visualises the location of the DBS electrode in the subthalamic nucleus (STN).

Decreased risk of Parkinson's disease in diabetic patients with thiazolidinediones therapy: An exploratory meta-analysis.

It has been found that thiazolidinediones (TZDs) may play a protective role in animal models of Parkinson's disease (PD), while the results remain controversial whether TZDs protect against Parkinson's disease in humans. The purpose of this meta-analysis is to explore the association between TZDs use and the incidence of PD in diabetic patients.

Focused ultrasound in Parkinson's disease: A twofold path toward disease modification.

A major unmet need in Parkinson's disease (PD) is to slow the inexorable progression of neurodegeneration. Clinical trials that evaluated promising pharmacological strategies have repeatedly failed. Nonetheless, the advent of focused ultrasound provides new opportunities toward the goal of developing a safe and effective disease-modifying therapy for PD. Here we discuss the rationale, possible avenues, and challenges along this path, exploiting the potential of focused ultrasound for (1) performing focal th...

Efficacy of oral administration of licorice as an adjunct therapy on improving the symptoms of patients with Parkinson's disease, A randomized double blinded clinical trial.

Licorice preparations are used as neuroprotective remedies in Persian ethnomedicine, in order to prevent from disabilities in neurodegenerative conditions like Parkinson's disease (PD).

Frailty in Parkinson's Disease: A Systematic Review.

Parkinson's disease (PD) and frailty are two conditions that are increasingly common with advancing age, yet little is known about their relationship.

Blood-brain barrier opening with focused ultrasound in experimental models of Parkinson's disease.

Parkinson's disease has many symptomatic treatments, but there is no neuroprotective therapy currently available. The evolution of this disease is inexorably progressive, and halting or stopping the neurodegenerative process is a major unmet need. Parkinson's disease motor features at onset are typically limited to 1 body segment, that is, focal signs, and the nigrostriatal degeneration is highly asymmetrical and mainly present in the caudal putamen. Thus, clinically and neurobiologically the process is fai...

Subthalamic nucleus deep brain stimulation improves dyskinesias in Parkinson's disease beyond levodopa reduction.

Bilateral subthalamic nucleus deep brain stimulation (STN DBS) improves motor fluctuations and dyskinesias in patients with Parkinson's disease (PD). Dyskinesia improvement with STN DBS is believed to result entirely from levodopa reduction. However, some studies suggest that STN DBS may also directly suppress dyskinesias. To determine whether bilateral STN DBS improves dyskinesias beyond what would be expected from levodopa reduction alone, we analyzed pre-operative and post-operative dyskinesia scores (...
