Microbiota and the gut-brain-axis: Implications for new therapeutic design in the CNS

Biomarkers, Constipation, Gut Microbiota, Gut-Brain axis, Parkinson's Disease, Pre-PD, Vagal Nerve /

The recent revelation that the gut microbiome, home to approximately 100 trillion microorganisms, is implicated in the development of both health and disease has spurred an exponential increase in interdisciplinary research involving gut microbiology. In all this hype, there is a need to better understand and contextualize the emerging evidence for the role of the gut microbiota in […]

The emerging understanding of gut microbiota as ‘metabolic machinery’ influencing many aspects of physiology has gained substantial attention in the field of psychiatry. This is largely due to the many overlapping pathophysiological mechanisms associated with both the potential functionality of the gut microbiota and the biological mechanisms thought to be underpinning mental disorders. In this

Oral ingestion of the environmental toxicant trichlorethylene in
rats induces alterations in the gut microbiome: relevance to
idiopathic Parkinson’s disease

Microbial alterations within the gut microbiome appear to be a common feature of individuals with Parkinson’sdisease (PD), providing further evidence for the role of the gut-brain axis in PD development. As a major site ofcontact with the environment, questions have emerged surrounding the cause and effect of alterations to the gutmicrobiome by environmental contaminants associated

Gut microbiome alterations in fecal samples of treatment-naïve de novo Parkinson’s disease patients

Gut microbiota alterations in Parkinson’s disease (PD) have been found in several studies and are suggested to contribute to the pathogenesis of PD. However, previous results could not be adequately adjusted for a potential confounding effect of PD medication and disease duration, as almost all PD participants were already using dopaminergic medication and were included

Prodromal Parkinson’s disease: hype or hope for disease-modification trials?

Biomarkers, Parkinson's Disease, Pre-PD /

The ultimate goal in Parkinson’s disease (PD) research remains the identification of treatments that are capable of slowing or even halting the progression of the disease. The failure of numerous past disease-modification trials in PD has been attributed to a variety of factors related not only to choosing wrong interventions, but also to using inadequate

High Pesticide Exposure Events and Dream-Enacting Behaviors Among US Farmers

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

Dream-enacting behavior is a characteristic feature of rapid eye movement sleep behavior disorder, the most specific prodromal marker of synucleinopathies. Pesticide exposure may be associated with dream-enacting behaviors, but epidemiological evidence is limited. This study provides the first epidemiological evidence that high pesticide exposures may be associated with a higher risk of dream-enacting behaviors. CLICK

A metabolic biomarker predicts Parkinson’s disease at the early stages in patients and animal models

Biomarkers, Metabolites, Parkinson's Disease, Pre-PD /

Care management of Parkinson’s disease (PD) patients currently remains symptomatic, mainly because diagnosis relying on the expression of the cardinal motor symptoms is made too late. Earlier detection of PD therefore represents a key step for developing therapies able to delay or slow down its progression. From our translational study, which included 3 animal models

Role of Microbiota-Gut-Brain Axis in Regulating
Dopaminergic Signaling

Parkinson's Disease, Pre-PD, Probiotics, Prebiotics and Symbiotics /

Dopamine is a neurotransmitter that plays a critical role both peripherally and centrally invital functions such as cognition, reward, satiety, voluntary motor movements, pleasure, and motivation. Optimal dopamine bioavailability is essential for normal brain functioning and protectionagainst the development of neurological diseases. Emerging evidence shows that gut microbiotahave significant roles in maintaining adequate concentrations of

The promise of psychedelic research

Ayahuasca, Parkinson's Disease, Pre-PD /

The use of psychedelics as medicines and for overall better brain health is potentially one of the mosttransformative developments given their immediate and long-lasting therapeutic effects across a plethoraof neuropsychiatric disorders and, more recently, some neurodegenerative diseases. The US psychedelicdrugs market is forecasted to grow by 16.3% by 2027 due to the increasing prevalence of

α-Synuclein in Parkinson’s disease and advances in detection

A-Synuclein, Biomarkers, Parkinson's Disease, Pre-PD /

Parkinson’s disease (PD) is a threatening neurodegenerative disorder that seriously affects patients’ life quality. Substantial evidence links the overexpression and abnormal aggregation of alpha-synuclein (α-Syn) to PD. α-Syn has been identified as a characteristic biomarker of PD, which indicates its great value of diagnosis and designing effective therapeutic strategy. This article systematically summarizes the pathogenic
