Phenoconversion Risk Factors in Rapid Eye Movement Sleep Behavior Disorder

Biomarkers, Enviromental, iRBD, Parkinson's Disease, Pesticides, Pre-PD /

A multicenter cohort of idiopathic/isolated rapid eye movement sleep behavior disorder (iRBD) was studied to determine any predictive factors for α-synuclein–related neurodegenerative illnesses. At the start of the study, patients with iRBD from 12 different sites were given a complete assessment for potential environmental and lifestyle risk factors using a standardized questionnaire. Patients were then […]

Self-reported periodontitis and C-reactive protein in
Parkinson’s disease: a cross-sectional study of
two American cohorts

endondonics, Oral Microbiome, Parkinson's Disease, Periodontitis, Root Canal /

Periodontitis triggers systemic repercussions, such as elevated levels of high-sensitive C-reactive protein (hs-CRP). This has neverbeen studied within Parkinson’s Disease (PD). The aim of this study is to compare hs-CRP levels of self-reported periodontitis casesversus cases without periodontitis in PD patients. Data from the National Health and Nutrition Examination Survey (2015–2016 and2017–2018 waves) were analyzed.

Fermented brown rice beverage distinctively modulates the gut microbiota in Okinawans with Metabolic Syndrome: a randomized controlled trial

Butyrate, Diet and Exercise, Fermented Foods, Gut Dysbiosis, Gut Microbiota, Parkinson's Disease, Pre-PD, Probiotics, Prebiotics and Symbiotics, Short Chain Fatty Acids /

Accumulating evidence to date suggests that brown rice is superior to white rice in regards to its beneficial impact on a number of risk factors of the metabolic syndrome (MetS). However, little is known about the influence of fermented brown rice beverage on the gut microbiota in humans. We therefore hypothesized that its impact would

Environmental factors shaping the gut microbiome in a Dutch population

Diet and Exercise, Enviromental, Gut Dysbiosis, Gut Microbiota, Metabolites, Parkinson's Disease /

The gut microbiome is associated with diverse diseases1,2,3, but a universal signature of a healthy or unhealthy microbiome has not been identified, and there is a need to understand how genetics, exposome, lifestyle and diet shape the microbiome in health and disease. Here we profiled bacterial composition, function, antibiotic resistance and virulence factors in the

Gut microbiota is causally associated with poststroke cognitive impairment through lipopolysaccharide and butyrate

Butyrate, Gut Dysbiosis, Gut Microbiota, Lipopolysaccharides (LPS), Metabolites, Short Chain Fatty Acids /

Our data indicate a cause–effect relationship between gut microbiota and PSCI for the first time, which is likely mediated by inflammation-regulating metabolites including LPS and butyrate. CLICK TO REVIEW

Evolution patterns of probable REM sleep behavior disorder predicts Parkinson’s disease progression

iRBD, Parkinson's Disease, Pre-PD /

The course of REM sleep behavior disorder (RBD) variates in the early stage of Parkinson’s disease. We aimed to delineate the association between the evolution pattern of probable RBD (pRBD) and the progression of Parkinson’s disease (PD). 281 de novo PD patients from the Parkinson’s Progression Markers Initiative database were included. Patients were followed up

Facts and controversies regarding oral health in Parkinson’s disease:
A case-control study in Spanish patients

Diet and Exercise, endondonics, Oral Microbiome, Parkinson's Disease, Pre-PD, Root Canal /

Oral disorders are frequent in PD. Good knowledge of these alterations will allow us to design a specific preventive protocol. Some oral alterations may be a sign of diagnostic alert or progression of PD. CLICK TO REVIEW

Effects of a Ketogenic Diet on Symptoms, Biomarkers, Depression, and Anxiety in Parkinson’s Disease: A Case Study

Diet and Exercise, Parkinson's Disease /

The ketogenic diet has grown in popularity as an alternative or adjunct to medication therapy for Parkinson’s disease (PD) and other neurodegenerative diseases (NDD). Traditional medication therapies often fail to produce desired improvements in PD symptoms and can have little or no effect on symptoms of depression and anxiety that often accompany a PD diagnosis. We

Gut microbiota and inflammation in
Parkinson’s disease: Pathogenetic and
therapeutic insights

A-Synuclein, Butyrate, Diet and Exercise, Gut Dysbiosis, Gut Microbiota, Parkinson's Disease, Pre-PD, Probiotics, Prebiotics and Symbiotics, Short Chain Fatty Acids /

Parkinson’s disease (PD) is a progressive neurodegenerative disease characterized by dopaminergic neuronal loss andα-synuclein (α-syn) aggregation. With the acceleration of population aging process, the incidence of PD is expected toincrease, putting a heavy burden on the whole society. Recent studies have found the alterations of gut microbiota (GM) inPD patients and the clinical relevance of

Progression of intestinal permeability changes and alpha-synuclein expression in a mouse model of Parkinson’s disease

A-Synuclein, Gut Microbiota, Gut Permeability / Leaky Gut, Gut-Brain axis, Parkinson's Disease, Pre-PD /

Parkinson’s disease (PD) is a multifocal degenerative disorder for which there is no cure. The majority of cases are sporadic with unknown etiology. Recent data indicate that untreated patients with de novo PD have increased colonic permeability and that both de novo and premotor patients have pathological expression of α-synuclein (α-syn) in their colon. Both
