The paper investigates genetic and causal links between post-traumatic stress disorder and rapid-eye-movement sleep behavior disorder using polygenic risk scores, genetic correlation, and Mendelian randomization analyses.

The paper investigates genetic interactions between SNCA and APOE in synucleinopathies using GWAS data and finds no significant epistatic interactions after multiple testing correction.

This study examines the association of NPC1 variants with Parkinson's disease, REM-sleep behavior disorder, and dementia with Lewy bodies in European cohorts and finds no significant associations.

This study identifies five RBD risk loci through genome-wide association and finds differential expression of SNCA-AS1 and SCARB2 in brain regions.

This study investigates the association between GBA variants and risk for isolated REM sleep behavior disorder (iRBD) and conversion to neurodegeneration, finding higher prevalence and increased conversion rates in carriers.

This study identifies SNCA risk variants specific to RBD and overt synucleinopathies, finding distinct associations and opposite effects at the 3' end of SNCA.

This paper uses deep learning models on EEG spectrograms to diagnose and predict progression of REM Behavior Disorder, finding high accuracy in distinguishing patients who later develop Parkinson's or DLB from healthy controls.

The paper uses EEG algorithmic complexity metrics to predict neurodegeneration in idiopathic RBD, finding decreased complexity correlates with poor prognosis.
