Isolated dream-enactment behaviours as a prodromal hallmark of rapid eye movement sleep behaviour disorder
J Sleep Res. 2022 Nov 21:e13791. doi: 10.1111/jsr.13791. Online ahead of print.ABSTRACTRecurrent dream-enactment behaviours (DEB) and rapid eye movement (REM) sleep without atonia (RSWA) are two diagnostic hallmarks of REM sleep behaviour disorder (RBD), a specific prodrome of α-synucleinopathy. Whilst isolated RSWA (without DEB) was suggested as a prodrome of RBD, the implication of 'isolated' recurrent DEB remains under-investigated. In this cross-sectional study, we sought to investigate neurodegenerative markers amongst the first-degree relatives (FDRs, aged >40 years) of patients with RBD who underwent clinical as...

J Sleep Res. 2022 Nov 18:e13789. doi: 10.1111/jsr.13789.

Symptom dynamics among nightmare sufferers: An intensive longitudinal study
J Sleep Res. 2022 Nov 9:e13776. doi: 10.1111/jsr.13776. Online ahead of print.ABSTRACTNightmares are considerably prevalent in the general population and are known to be closely associated with a variety of mental disorders. However, not much is known about the immediate antecedents and consequences of nightmares. Therefore, we used intensive longitudinal assessments to investigate the night-to-night within-person associations between nightmares on the one hand and fear of sleep, somatic as well as cognitive pre-sleep arousal, and sleep quality on the other hand. Young women with regular nightmares (n = 16) maintained a sl...

Nightmare distress is related to traumatic childhood experiences, critical life events and emotional appraisal of a dream rather than to its content
J Sleep Res. 2022 Nov 5:e13779. doi: 10.1111/jsr.13779. Online ahead of print.ABSTRACTNightmares are a substantial burden for sleep quality. Previous studies have shown that traumatic experiences can increase the probability of nightmares, and also waking-life distress can enhance this effect. There is evidence that the intensity of negative dream emotions is more responsible for rating a dream as a nightmare than threatening dream contents. However, there is still a lack of research concerning effects on nightmare distress. We hypothesise that traumatic childhood experiences (such as emotional abuse, obtained by the Child...

An observatory on changes in dreaming during a pandemic: a living systematic review (part 1)
J Sleep Res. 2022 Nov 1:e13742. doi: 10.1111/jsr.13742. Online ahead of print.ABSTRACTA 'new' way of dreaming has emerged during the pandemic, enhancing the interest of psychological literature. Indeed, during the years of the spread of coronavirus disease 2019 (COVID-19), many studies have investigated dream-related phenomena and dreaming functions. Considering the constant and rapid emergence of new results on this topic, the main aim of this study was to create an 'observatory' on the short- and long-term consequences of the COVID-19 pandemic on dreaming, by means of a living systematic review. The baseline results are ...
