Molecular glucose imaging reveals functional brain reconfiguration by subthalamic deep brain stimulation in Parkinsonian rats

Translational Neurodegeneration
Background In order to elucidate the neuromodulatory mechanisms underlying therapeutic subthalamic deep brain stimulation (DBS), we here reverse-translate a methodological pipeline that integrates neurostimulation effect parameterization and molecular ...

Effects of aging on nitrergic neurons in human striatum and subthalamic nucleus

Arquivos de Neuro-Psiquiatria, 2015
Nitric oxide (NO) is a major neurotransmitter associated with motor control in basal ganglia. Movement disorders, as essential tremor and Parkinson’s disease, are more prevalent on aged individuals.

Continuous Subcutaneous Versus Intestinal Levodopa Infusion for Parkinson's Disease: A Real‐World, Monocentric, Observational Study and Critical Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Subcutaneous foslevodopa‐foscarbidopa (SCFF) is a novel, non‐surgical dopaminergic infusion therapy for better controlling motor fluctuations in advanced Parkinson's disease (PD). However, there are scarce real‐world data on efficacy, adverse events and comparisons with other infusion strategies. Objectives Here, we aimed to provide

Quantifying local field potential dynamics with amplitude and frequency stability between ON and OFF medication and stimulation in Parkinson's disease

Neurobiology of Disease
Neural oscillations are critical to understanding the synchronisation of neural activities and their relevance to neurological disorders. For instance, the amplitude of beta oscillations in the subthalamic nucleus has gained extensive attention, as it ...

Dyskinesias and the subthalamic nucleus.

Annals of neurology, 2000
Severe dyskinesias or ballism can occur following hemorrhagic events in the subthalamic nucleus (STN), and it has recently been established that the STN plays a major role in the pathophysiology of the motor dysfunction of Parkinson's disease (PD) and that STN inhibition improves parkinsonian dysfunction.

Risk‐Benefit Considerations in Deep Brain Stimulation Discontinuation for Late‐Stage Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Management of deep brain stimulation (DBS) in late‐stage Parkinson's disease (LSPD) remains challenging, particularly when deciding whether to continue or discontinue stimulation, and evidence on risk–benefit considerations is limited. Objectives To identify key factors to improve decision‐making in DBS management for LSPD patients.

Subthalamic Nucleus Deep Brain Stimulation Improves Kinetic Tremor in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Although resting tremor is a characteristic feature of Parkinson's disease (PD), many patients also suffer from action tremor. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is effective in reducing motor symptoms. However, it is unclear to what extent STN‐DBS improves action tremor in PD, particularly kinetic tremor.

Longitudinal Videofluorographic Dysphagia Measures in Progressive Supranuclear Palsy

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Dysphagia can lead to fatal aspiration pneumonia in progressive supranuclear palsy (PSP). Little is known about the longitudinal progression of dysphagia or whether it differs across PSP clinical variants. Objectives To characterize longitudinal changes in dysphagia across PSP variants and determine relationships with disease ...
