The researchers have studied a group of patients suffering from REM Sleep Behavior Disorder (RBD), a condition where the patients physically act vivid dreams with vocalizations and movements. If a patient e.g. dreams that they are running, their legs will move as if they were actually running. The sleep disorder is often discovered by a […]
These results support the idea that RBD is an important marker of rapid progression in PD motor and non-motor symptoms and suggest that the atrophy in the left insula and caudate nucleus might be the underlying neurobiological mechanisms of the poorer prognosis in PD patients with RBD.

Owing to the growing elderly population, age-related problems are gaining increasing attention from the scientific community. With senescence, the intestine undergoes a spectrum of changes and infirmities that are likely the causes of overall aging. Therefore, identification of the aged intestine and the search for novel strategies to rescue it, are required. Although progress has

We found significantly altered SCFA levels in patients with autism spectrum disorder (ASD), affective disorders, multiple sclerosis (MS) and Parkinson’s disease (PD). NonSCFAs yielded less significantly distinct changes in faecal levels of patients and healthy controls, with the majority of findings were derived from urinary and blood samples. Preclinical studies have implicated different bacterial metabolites
The Role of Gut Bacterial Metabolites in Brain Development, Aging and Disease Read More »
Gut microbial function is altered in PD, characterized by differentially abundant metabolic features that provide important biological insights into gut-brain pathophysiology. Their clinical relevance further supports a role for microbial-metabolites as potential targets for the development of new biomarkers and therapies in PD. CLICK TO REVIEW
Iron deficiency is the most frequent nutritional deficiency in the world with an estimated 1.4 billion people affected. The usual way to fight iron deficiency is iron fortification, but this approach is not always effective and can have undesirable side effects including an increase in the growth and virulence of gut bacterial pathogens responsible for

In this work, we investigated the ability of amyloid fibrils derived from two food proteins to heterologously seed the aggregation of the PD-related aSyn protein. While β-lactoglobulin amyloid fibril seeds were not able to induce aSyn aggregation, we identified a fibril surface–mediated nucleation mechanism for the seeding of aSyn aggregation by hen egg white lysozyme

Interestingly, we found that TCE not only induced LRRK2 kinase activity in the brain, but produced a significant dopaminergic lesion in the nigrostriatal tract, elevated oxidative stress, and caused endolysosomal dysfunction and α-synuclein accumulation. Together, these data suggest that TCE-induced LRRK2 kinase activity contributed to the selective toxicity of dopaminergic neurons. We conclude that gene-environment interactions
Parkinson’s disease (PD) is among the most common chronic neurodegenerative conditions, affecting 1% of those over 60 years of age, and involves motor and non-motor impairments. Alterations in normal physiology may become apparent years – in some cases, 10–20 years – before established diagnostic criteria are met. Thus, better clinical outcomes may result when practitioners
