Rapid eye movement sleep behavior disorder (RBD) contributes to injury due to the alteration of the expected atonia during rapid eye movement (REM) sleep. It occurs before the overt signs of Parkinson’s disease (PD). The co-expression of PD and RBD is characterized by non-tremor predominant subtype and higher incidence of freezing. Freezing of gait (FOG) […]
Parkinson’s disease is predominantly classified as a movement disorder. Beyond the textbook definition of rigidity, tremors, and bradykinesia, Parkinson’s disease encompasses an entire entity of non-motor symptom complexes that can precede the motor features by many years. Despite their significant clinical importance, the awareness of non-motor symptoms is quite negligible. Sleep disorders, gastrointestinal dysfunction, olfactory

A simple eye exam combined with powerful artificial intelligence (AI) machine learning technology could provide early detection of Parkinson’s disease, according to research being presented at the annual meeting of the Radiological Society of North America (RSNA). CLICK TO REVIEW

Finally, decreased α-synuclein oligomer accumulation and mitochondrial dysfunction in mice correlated with nuclear REST and PGC-1α in protected SN GABAergic neurons, when compared to vulnerable dopaminergic neurons. Our findings show that increased levels of α-synuclein oligomers cause dopaminergic neuronal-specific dysfunction through mitochondrial toxicity, which can be attenuated by REST in an early model of Parkinsonian
The frequencies of symptoms and abnormal findings in PD patients were as follows: hyposmia 82.4%, substantia nigra hyperechogenicity 75.4%, history of anxiety or depression disorder 29.5%, constipation 22.1%, and REM (rapid eye movement) sleep behavior disorder 22%. Conclusion: Baseline characteristics of patients enrolled in the BIO-PD study are comparable to other de novo PD cohorts,
Clinically, we observed a reduction in non-motor symptoms load in PD + RS. The reference-based analysis of metagenomes highlighted stable alpha-diversity and beta-diversity across the three groups, including bacteria producing SCFAs. Reference-free analysis suggested punctual, yet pronounced differences in the metagenomic signature in PD + RS. RESISTA-PD highlights that a prebiotic treatment with RS is
Current research shows that probiotics and prebiotics have a good preventive effect on Alzheimer’s disease, Parkinson’s disease, depression, autism spectrum disorders and other neurological and mental diseases. Based on this, we review the relevant research on the pathogenesis of probiotics and prebiotics and neuropsychiatric diseases, in an attempt to providing new ideas for exploring the
Findings highlight significant differences in the fecal microbiome and metabolome in patients with Parkinson’s disease and control subjects, demonstrating an important connection between the brain and gut that could influence the disease process and progression. CLICK TO REVIEW
