The paper shows that genetic variants at the alpha-synuclein locus influence gut microbiome dysbiosis in Parkinson's disease.

This study conducts a metabolomics analysis of cervical dystonia, identifying 289 significant metabolic differences and 9 associated biological pathways.

The paper identifies brain-linked CSF biomarkers in Alzheimer’s disease using proteomics, revealing altered levels in both brain and CSF across different disease stages.

This study identifies three clusters of gut microbiota associated with Parkinson's disease, including overabundance of opportunistic pathogens.

This study finds that Parkinson’s disease patients have impaired perception of whole-body motion during balance perturbations, which correlates with worse balance ability.
