Background: Parkinson's disease is associated with a dysbiotic, proinflammatory gut microbiome, disruptions to intestinal barrier functions, and immunological imbalance. Microbiota-produced short-chain fatty acids, such as propionic and butyric acid promote gut barrier integrity and immune regulation, but their impact on Parkinson's disease pathology remains mostly unknown.Methods: In a randomized double-blind prospective study, 72 people with… Continue reading Supplementation with #short-chain fatty acids and a #prebiotic improves clinical outcome in #Parkinson’s disease: a randomized double-blind prospective study

#Electrophysiological correlates of dynamic #cycling in #Parkinson’s diseaseAuthor
Physical exercise like dynamic cycling has shown promise in enhancing motor function in Parkinson’s disease (PD). We examined the underlying mechanisms of dynamic cycling in PD, emphasizing its impact on the activity of the subthalamic nucleus (STN), a pivotal region within the basal ganglia.MethodsThe investigation involved 100 dynamic cycling sessions conducted among nine PD individuals.… Continue reading #Electrophysiological correlates of dynamic #cycling in #Parkinson’s diseaseAuthor
Classification of #Parkinson’s disease and isolated #REM sleep behaviour disorder: delineating progression markers from the sebum volatilome
Parkinson’s Disease (PD) has been associated with a distinct odour, emanating from the skin and strongest in sebum-rich areas. Here, volatile components from sebum were analysed directly with Thermal Desorption Gas Chromatography - Mass Spectrometry. We analysed samples from subjects with clinically established PD (n = 46), controls (n = 28) and participants with isolated REM sleep behaviour disorder… Continue reading Classification of #Parkinson’s disease and isolated #REM sleep behaviour disorder: delineating progression markers from the sebum volatilome
#Ambroxol as a #Treatment for #Parkinson Disease #DementiaA Randomized Clinical Trial
Importance Carrying a variation in the gene for β-glucocerebrosidase is a major risk factor for Parkinson disease dementia (PDD), and raising β-glucocerebrosidase levels lowers α-synuclein in cell and animals. Ambroxol is a chaperone for β-glucocerebrosidase, which increases the levels of β-glucocerebrosidase.Objective To examine the safety and tolerability of ambroxol in PDD, test the efficacy of… Continue reading #Ambroxol as a #Treatment for #Parkinson Disease #DementiaA Randomized Clinical Trial
Propagation of pathologic α-synuclein from #kidney to brain may contribute to #Parkinson’s disease
The pathogenesis of Lewy body diseases (LBDs), including Parkinson’s disease (PD), involves α-synuclein (α-Syn) aggregation that originates in peripheral organs and spreads to the brain. PD incidence is increased in individuals with chronic renal failure, but the underlying mechanisms remain unknown. Here we observed α-Syn deposits in the kidneys of patients with LBDs and in… Continue reading Propagation of pathologic α-synuclein from #kidney to brain may contribute to #Parkinson’s disease
#Propranolol Reduces #Parkinson’s #Tremor and Inhibits Tremor-Related Activity in the Motor Cortex: A Placebo-Controlled Crossover Trial
AbstractObjectiveParkinson's disease (PD) resting tremor is thought to be initiated in the basal ganglia and amplified in the cerebello-thalamo-cortical circuit. Because stress worsens tremor, the noradrenergic system may play a role in amplifying tremor. We tested if and how propranolol, a non-selective beta-adrenergic receptor antagonist, reduces PD tremor and whether or not this effect is… Continue reading #Propranolol Reduces #Parkinson’s #Tremor and Inhibits Tremor-Related Activity in the Motor Cortex: A Placebo-Controlled Crossover Trial
Upper #Gastrointestinal Mucosal Damage and Subsequent Risk of #Parkinson Disease
Importance The gut-first hypothesis of Parkinson disease (PD) has gained traction, yet potential inciting events triggering Parkinson pathology from gut-related factors remain unclear. While Helicobacter pylori infection is linked to mucosal damage (MD) and PD, it is unknown how upper gastrointestinal MD from any source increases PD risk.Objective To evaluate any association between upper endoscopy findings of MD and… Continue reading Upper #Gastrointestinal Mucosal Damage and Subsequent Risk of #Parkinson Disease
#Acupuncture and #Sleep Quality Among Patients With #Parkinson DiseaseA Randomized Clinical Trial
Importance Poor sleep quality greatly impairs quality of life and accelerates deterioration in patients with Parkinson disease (PD), but current remedies remain limited. Acupuncture, used as an adjunctive therapy with anti-Parkinson medications, has shown positive effects in patients with PD. However, high-quality clinical evidence to support the effectiveness of acupuncture for patients with PD and poor… Continue reading #Acupuncture and #Sleep Quality Among Patients With #Parkinson DiseaseA Randomized Clinical Trial
The landscape of rare genetic variation associated with inflammatory #bowel disease and #Parkinson’s disease comorbidity
BackgroundInflammatory bowel disease (IBD) and Parkinson’s disease (PD) are chronic disorders that have been suggested to share common pathophysiological processes. LRRK2 has been implicated as playing a role in both diseases. Exploring the genetic basis of the IBD-PD comorbidity through studying high-impact rare genetic variants can facilitate the identification of the novel shared genetic factors underlying this… Continue reading The landscape of rare genetic variation associated with inflammatory #bowel disease and #Parkinson’s disease comorbidity
