Deciphering the prion-like behavior of pathogenic protein aggregates in neurodegenerative diseases

Neurodegenerative diseases are hitherto classified based on their core clinical features, the anatomical distribution of neurodegeneration, and the cell populations mainly affected. On the other hand, the wealth of neuropathological, genetic, molecular and biochemical studies have identified the existence of distinct insoluble protein aggregates in the affected brain regions. These findings have spread the use of a […]

Impact of Contaminants on Microbiota: Linking the Gut–Brain
Axis with Neurotoxicity

Autonmic nervous system, Gut Dysbiosis, Gut Microbiota, Gut-Brain axis, Parkinson's Disease /

: Over the last years, research has focused on microbiota to establish a missing link betweenneuronal health and intestine imbalance. Many studies have considered microbiota as criticalregulators of the gut–brain axis. The crosstalk between microbiota and the central nervous system ismainly explained through three different pathways: the neural, endocrine, and immune pathways,intricately interconnected with each

Clinical and imaging evidence of brain-first and body-first Parkinson’s disease

Braak’s hypothesis has been extremely influential over the last two decades. However, neuropathological and clinical evidence suggest that the model does not conform to all patients with Parkinson’s disease (PD). To resolve this controversy, a new model was recently proposed; in brain-first PD, the initial α-synuclein pathology arise inside the central nervous system, likely rostral to

Serum short-chain fatty acids and its correlation with motor and non-motor symptoms in Parkinson’s disease patients

Serum SCFAs are altered in PD patients, and the decrease of serum propionic acid level is correlated with motor symptoms, cognitive ability and non-depressed state. Thus, the gut microbial-derived SCFAs potentially affect Parkinson’s symptoms through the blood circulation. Propionic acid supplementation might ameliorate motor and non-motor symptoms of PD patients, although clinical trials are needed

Orthostatic Hypotension: JACC State-of-the-Art Review

Neurogenic orthostatic hypotension is a highly prevalent and disabling feature of autonomic failure due to both peripheral and central neurodegenerative diseases. Community-based epidemiological studies have demonstrated a high morbidity and mortality associated with neurogenic orthostatic hypotension. It is due to impairment of baroreflex-mediated vasoconstriction of the skeletal muscle and splanchnic circulation and is caused by damage

Association Between Parkinson’s Disease and Atrial Fibrillation: A Population-Based Study

A-Synuclein, Autonmic nervous system, Parkinson's Disease, Pre-PD /

Autonomic nervous system (ANS) dysfunction contributes to several non-motor symptoms of Parkinson’s disease (PD). In addition, ANS plays a role in the genesis and maintenance of atrial fibrillation (AF). This study investigated the temporal association between PD and AF. This study demonstrated that the premotor and early stages of PD were comorbid with AF, whereas
