Structural connectivity of low-frequency subthalamic stimulation for improving stride length in Parkinson's disease.

Background: A reduction in stride length is considered a key characteristic of gait kinematics in Parkinson's disease (PD) and has been identified as a predictor of falls. Although low-frequency stimulation (LFS) has been suggested as a method to improve gait characteristics, the underlying structural network is not well understood.

Objective: This study aims to investigate the structural correlates of changes in stride length during LFS (85 Hz).

Case report: Unilateral GPi DBS in secondary myoclonus-dystonia syndrome after acute disseminated encephalomyelitis.

Introduction: Deep brain stimulation (DBS) is an established and effective therapy for movement disorders. Here, we present a case of secondary myoclonus-dystonia syndrome following acute disseminated encephalomyelitis (ADEM) in childhood, which was alleviated by DBS. Using a patient-specific connectome analysis, we sought to characterise the fibres and circuits affected by stimulation.

Binaural acoustic stimulation in patients with Parkinson's disease.

Acoustic stimulation can improve motor symptoms in Parkinson's disease (PD) and might therefore represent a potential non-invasive treatment option. Scalp electroencephalography studies in healthy subjects indicate that specifically binaural beat stimulation (BBS) in the gamma frequency range is associated with synchronized cortical oscillations at 40 Hertz (Hz). Several studies suggest that oscillations in the gamma-frequency range (>30 Hz) serve a prokinetic function in PD.

Cost-Effectiveness of Device-Aided Therapies in Parkinson's Disease: A Structured Review.

Background: Despite optimal dopaminergic treatment most patients in moderate to advanced stages of Parkinson's disease (PD) experience progressively increasing disabilities, necessitating a shift from oral medication to device-aided therapies, including deep brain stimulation (DBS), intrajejunal levodopa-carbidopa infusion (IJLI), and continuous subcutaneous apomorphine infusion (CSAI). However, these therapies are costly, limiting their implementation.

Objectives: To perform a systematic review on cost-effectiveness analyses for device-aided therapies in PD.

Serum Uric Acid Levels and Non-Motor Symptoms in Parkinson's Disease.

Background: Previous studies have identified low serum uric acid (SUA) levels as a risk factor for the development of Parkinson's disease (PD). Prodromal PD mainly manifests as a complex of non-motor features, but the association between SUA levels and nonmotor symptoms (NMS) burden level in advanced PD patients is poorly studied.

Objective: To determine the association between SUA levels and NMS in PD patients.
