Predictors of children's outcomes in trauma-focused interventions are well documented. However, little is known about the role of higher-order cognitive processes, specifically executive function (EF) abilities, in determining children's responses to treatments specifically for trauma-related sleep disturbances. EF is independently related to PTSD reactions, sleep deficits, and nightmares....

To investigate the prevalence of REM sleep behavior disorder (RBD) in patients with inflammatory arthritis (IA) to ascertain if RBD could be an internal red flag signaling a fluctuating state of inflammation based on the theory of "protoconsciousness". One hundred and three patients with a confirmed diagnosis of IA were consecutively recruited. The patients underwent general (IA activity,...

The aim of this study was to investigate the effect of dream recall on the neurophysiological correlates of emotional processing. The hypothesis was that dream recall will produce an increased activation of fronto-limbic areas during an emotional task. Thirty-seven women were recruited and randomly assigned to two groups. Both groups were exposed to a visual task with emotional images (positive...

This research addressed the question of why some bereaved individuals dream of the deceased whereas others do not. Two studies were conducted. In one, participants were 268 U.S. residents (150 men, 116 women, 1 other, and 1 undisclosed), with an age range of 20 to 70 (M = 33.8), who had lost a romantic partner or spouse in the previous 12 to 24 months. The second study had 162 U.S. residents...

The current study examined the validity of the Nightmare Proneness Scale (NPS; Kelly, 2018) as measuring a personality disposition that predisposes individuals to experience frequent nightmares. The NPS and measures to estimate its convergent and discriminant validity were administered to a sample of 140 university students. The convergent validity of the scale was supported through significant...

Study objectives: Growing evidence suggests that nightmares have considerable adverse effects on waking behavior, possibly by increasing post-sleep negative emotions. Dysphoric reactions to nightmares are one component of nightmare severity for which the neural correlates are unknown. Here, we investigate possible neural correlates of nightmare severity in a sample of individuals who frequently...

Mind-wandering is associated with the simultaneous activation of a network of different brain regions known formally as the default mode network. Forward looking anxious mind-wandering (or worry) occurs when activity in this network is coupled with a biological fear response in the brain. The fear response constrains the con-tent of anxious mind-wandering, with imagined catastrophised scenarios...

Abstract Introduction The association of sleep disorders and post-traumatic stress disorder (PTSD) is almost universal. Nightmares are not only one of the most commonly associated but also featured as a diagnostic criterion for PTSD. PTSD-related nightmares are particularly distressing, may impair functioning and increase risk of suicide. No specific pharmacologic agent has been demonstrated to...

Reports of white dreams, the feeling of having had a dream experience without being able to specify this experience any further, make up almost one third of all dream reports, yet this phenomenon-until very recently-had not yet been in the focus of targeted investigations. White dreams are typically interpreted as forgotten dreams, and are sidelined as not being particularly informative with...

Sleep following learning benefits memory. One model attributes this effect to the iterative "reactivation" of memory traces in the sleeping brain, demonstrated in animal models. Although technical limitations prohibit using the same methods to observe memory reactivation in the human brain, the study of mental activity during sleep provides an alternative method of observing memory activation...
