Current study provides a valuable and highly informative dataset of EV-associated sncRNAsfrom plasma of iRBD and PD patients. We identified miRNA signature features that could serve asminimally-invasive, blood-based surveillance biomarkers for distinguishing iRBD or PD from healthyindividuals with high sensitivity, specificity, and accuracy.

Emerging evidence indicates that probiotics can influence the gut–brain axis to ameliorate somatic and behavioral symptoms associated with brain disorders. However, whether probiotics have effects on the electrophysiological activities of individual neurons in the brain has not been evaluated at a single-neuron resolution, and whether the neuronal effects of probiotics depend on the gut microbiome

Parkinson’s disease (PD) is one of the major progressive neurological disorders. It occurs due to a low level of achemical substance in the brain known as Dopamine, which controls the muscle movements of the body. In many cases, PDoccurs due to a low level of dopamine. PD generally appears in persons between the ages of
ABSTRACT Although the cepstral peak prominence (CPP) and its variant, the cepstral peak prominence smooth (CPPS), are considered to be robust acoustic measures for the evaluation of dysphonia, whether they are sensitive to capture early voice changes in Parkinson’s disease (PD) has not yet been explored. This study aimed to investigate the voice changes via
Study Objectives To analyze cognitive deficits leading to unsafe driving in patients with REM Sleep Behavior Disorder (RBD), strongly associated with cognitive impairment and synucleinopathy-related neurodegeneration.Methods Twenty isolated RBD (iRBD), 10 symptomatic RBD (sRBD), and 20 age- and education-matched controls participated in a prospective case-control driving simulation study. Group mean differences were compared with correlations

BACKGROUND: Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) is one of the earliest manifestations of α synucleinopathies. Brainstem pathophysiology underlying REM sleep behavior disorder has been described in animal models, yet it is understudied in living humans because of the lack of an in vivo brainstem nuclei atlas and to the limited magnetic
The proximity ligation assay (PLA) is a specific and sensitive technique for the detection of αSyn oligomers (αSyn-PLA), early and toxic species implicated in the pathogenesis of PD. We aimed to evaluate by skin biopsy the diagnostic and prognostic capacity of αSyn-PLA and small nerve fiber reduction in PD in a longitudinal study. αSyn-PLA was
Parkinson’s disease (PD) is a neurological disease impacting over six million people in the world. In addition to the motor symptoms of the disease, the disorder is accompanied with gastrointestinal problems. These include delayed transit time, disturbances in the microbial composition of the gut, inflammation in the intestine, structural changes in the epithelial lining and
Several studies have confirmed α-synuclein real-time quaking-induced conversion (αSyn-RTQuIC) assay to have high sensitivity and specificity for Parkinson’s disease. However, whetherthe assay can be used as a robust, quantitative measure to monitor disease progression, stratifydifferent synucleinopathies and predict disease conversion in patients with idiopathic REMsleep behaviour disorder remains undetermined. The aim of this study was
The DTI-ALPS index was significantly lower in patients with iRBD than in healthy controls, indicating the presence of glymphatic-system dysfunction in patients with iRBD. Our study also suggests that the DTI-ALPS index could serve as a biomarker for evaluating glymphatic-system function in neurological disorders. CLICK TO REVIEW
