Introduction and classical environmental risk factors for Parkinson.

Introduction and classical environmental risk factors for Parkinson. Rev Neurol (Paris). 2019 Jun 18;: Authors: Tranchant C Abstract Several environmental toxics are known to induce or to increase occurrence of Parkinson disease while other toxics can provoke basal ganglia necrosis and dopa resistant parkinsonism. After this introduction, the relationship between environment and parkinsonism will be illustrated by 3 short papers: interaction gene-environment, manganese induced Parkinsonism and the Caribbean Food toxins Parkinson plus syndromes.

Conclusion: It seems possible to identify a morphologic intestinal disease substrate in Parkinson's disease by H&E staining, showing ganglion cell pycnosis and degeneration in both plexa. This finding may indicate a potential to diagnose enteric neuropathy in highly accessible sites. PMID: 31321021 [PubMed]

Publication date: Available online 19 July 2019Source: NeuroscienceAuthor(s): Valeria Belluscio, Samuel Stuart, Elena Bergamini, Giuseppe Vannozzi, Martina ManciniAbstractTurning elicits Freezing of Gait (FoG) episodes in people with Parkinson's disease (PD) and is thought to require higher cortical control compared to straight ahead gait. Functional near infrared spectroscopy (fNIRS) has been used to examine prefrontal cortex (PFC) activity while walking, but the relationship between PFC activity and turn performance remains unclear. The aim of this pilot study was to examine PFC activity during turning in PD and healthy ...

In the past, a lack of internationally recognized 25(OH)D reference measurement procedures and reference standard materials led to unstandardized serum total 25(OH)D results among re...

AbstractMicrosatellite repeat expansion disease loci can exhibit pleiotropic clinical and biological effects depending on repeat length. Large expansions inC9orf72 (100s –1000s of units) are the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD). However, whether intermediate expansions also contribute to neurodegenerative disease is not well understood. Several studies have identified intermediate repeats in Par kinson’s disease patients, but the association was not found in autopsy-confirmed cases. We hypothesized that intermediateC9orf72 repeats are a genet...

ConclusionsArmodafinil, modafinil, and methylphenidate were associated with a decreased risk of parkinsonism, as were β-agonists. Of the β-blockers, only propranolol was associated with increased risk. Healthcare database analyses that incorporate scientific rigor provide insight and direction for drug discovery efforts. These findings show association not causality; however, they offer considerable support to th e association between β-adrenergic receptor modulation and risk of Parkinson’s disease.
