In March, to mark the launch of a Luxembourg National Sleep Study and World Sleep Day, NCER-PD organised three webinars in collaboration with several Luxembourg hospitals. The Centre Hospitalier de Luxembourg offered several presentations on sleep apnoea, narcolepsy and insomnia. The Centre Hospitalier du Nord discussed about the Restless Legs Syndrome, and the Robert Schuman Hospital group addressed REM sleep behaviour disorder (RBD) and the links between neurodegenerative diseases and RBD.
