Research progress on the association between Parkinson′s disease and inflammatory bowel disease in genetics and gut microbiota / 中华神经科杂志

Parkinson′s disease (PD) is a common degenerative disease of central nervous system. PD is closely related to gastrointestinal diseases in comorbidity studies, and the “gut brain axis” disorder may be involved in their relationship. In recent years, relevant studies have suggested that there are genetic and epidemiological evidences to link PD with inflammatory bowel disease (IBD). This article reviews the relationship between PD and IBD from the genetic evidence and the relevant concept of “gut brain axis”.

Advances in research on myoclonus-dystonia syndrome / 中华神经科杂志

Myoclonus-dystonia syndrome (MDS) is a special type of dystonia-plus syndromes. It is an autosomal-dominant movement disorder syndrome characterized by myoclonus and dystonia and accompanied by certain mental symptoms. The disorder usually occurs in childhood. Myoclonus and dystonia are usually involved in upper limbs, trunk and neck. The main pathogenic gene of MDS is ε-sarcoglycan gene (SGCE). Up to date, the mechanism that how this gene leads to the disease is not clear. The continuous progress of MDS can cause disability and bring great pain to patients and their families. In recent years, significant progress has been made in the research of this disease. This article will systematically review the pathogenesis, clinical phenotype, genetics, diagnostic criteria, differential diagnosis and treatment of MDS.
