Sleep Disorder-Night Terrors Disorder
Sleep terrors are classified as a parasomnia — an undesirable behavior or experience during sleep. Sleep terrors are a disorder of arousal, meaning they occur during N3 sleep, the deepest stage of non-rapid eye movement (NREM) sleep. Another NREM disorder is sleepwalking, which can occur together with sleep terrors.

- From burlesque to horror: a century of sleepwalking on the silver screenby Marie-Amelie Dalloz on August 3, 2021
BACKGROUND: Long before being described as a disorder, sleepwalking was considered as a mysterious phenomenon inspiring artwork. From the early beginning of cinema, sleepwalkers were shown to populations, playing a crucial role in storytelling and collective knowledge.
- Evaluation of the effects of shift work on parasomnia prevalenceby Duygu Kurt Gök on June 10, 2021
Shift work is increasingly common in industrialized countries but is associated with numerous health problems, especially sleep disorders. This study compared the frequency of NREM (confusional arousal, sleep terrors, sleepwalking, sleep-related eating disorder), REM parasomnias (REM sleep behavior disorder, nightmare disorder), and isolated symptoms/normal variants (sleeptalking) between shift workers and daytime workers. A total of 1473 participants in 3 different professional groups and...
- Grumpy face during adult sleep: A clue to negative emotion during sleep?by Jean-Baptiste Maranci on April 30, 2021
Negative facial expressions and frowns have been studied (albeit more rarely than smiles) in fetus' and neonate' sleep, but they have not been investigated during adult sleep. Video polysomnography (including corrugator muscle electromyography and face-focussed video) was used to study negative facial expressions in sleeping adults, including healthy subjects and patients with/out parasomnia. Frowns were observed during sleep in 89/91 (97.8%) adults during normal (29 healthy subjects) and...
