Abnormal timing of slow wave synchronization processes in non-rapid eye movement sleep parasomnias.

Sleep 2022 May 24. Epub 2022 May 24.

Center for Investigation and Research on Sleep, Lausanne University Hospital (CHUV), 1011 Lausanne, Switzerland.

Study Objectives: Sleepwalking, confusional arousals, and sleep terrors are parasomnias occurring out of non-rapid eye movement (NREM) sleep. Several previous studies have described EEG changes associated with NREM parasomnia episodes, but it remains unclear whether these changes are specific to parasomnia episodes or whether they are part of the normal awakening process. Here we directly compared regional brain activity, measured with high-density (hd-) EEG, between parasomnia episodes and normal awakenings (without behavioral manifestations of parasomnia).

Relevance of sleep and associated structural changes in GBA1 mouse to human rapid eye movement behavior disorder.

Sci Rep 2022 May 13;12(1):7973. Epub 2022 May 13.

Department of Neuroimaging, Sleep and Brain Plasticity Centre, Institute of Psychiatry, Psychology and Neuroscience (IoPPN), King's College London (KCL), De Crespigny Park, Box 089, London, SE5 8AF, UK.

Rapid eye movement (REM) sleep behaviour disorder (RBD) is a REM parasomnia that often predicts the later occurrence of alpha-synucleinopathies. Variants in the gene encoding for the lysosomal enzyme glucocerebrosidase, GBA, strongly increase the risk of RBD. In a GBA1-mouse model recently shown to mimic prodromal stages of α-synucleinopathy, we now demonstrate striking REM and NREM electroencephalographic sleep abnormalities accompanied by distinct structural changes in the more widespread sleep neurocircuitry.
