Post-traumatic stress disorder and REM-sleep behavior disorder: exploring genetic associations and causal links

Morvarid Ghamgosar Shahkhali, Lang Liu, Mohammad H. Ghamgosar Shahkhali, Eric Yu, Farnaz Asayesh, Jamil Ahmad, Meron Teferra, Isabelle Arnulf, Pauline Dodet, Yo‐El S. Ju, Michele T.M. Hu, Jacques Yves Montplaisir, Jean‐François Gagnon, Alex Désautels, Abubaker Ibrahim, , Ziv Gan‐Or

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.
