Abstract/Results: ABSTRACT:
Nightmares are intense, emotionally negative mental experiences that usually occur during late-night sleep and result in abrupt awakenings. Questionnaire-based studies have shown that nightmares are related to impaired sleep quality; however, the polysomnographic profile of nightmare subjects has been only scarcely investigated. We investigated the sleep architecture of 17 individuals with frequent nightmares and 23 control subjects based on polysomnographic recordings of a second night spent in the laboratory after an adaptation night. Nightmare subjects in comparison with control subjects were characterized by impaired sleep architecture, as reflected by reduced sleep efficiency, increased wakefulness, a reduced amount of slow wave sleep, and increased nocturnal awakenings, especially from Stage 2 sleep. While these differences were independent of the effects of waking psychopathology, nightmare subjects also exhibited longer durations of REM sleep that was mediated by heightened negative affect. Our results support that nightmares are related to altered sleep architecture, showing impaired sleep continuity and emotion-related increase in REM propensity.

Title:
Disturbed dreaming and the instability of sleep: Altered nonrapid eye movement sleep microstructure in individuals with frequent nightmares as revealed by the cyclic alternating pattern
Publication year: 2013
URL:
http://www.ncbi.nlm.nih.gov/pubmed/23449753
Abstract/Results: ABSTRACT:
STUDY OBJECTIVES:
Nightmares are disturbing mental experiences during sleep that usually result in abrupt awakenings. Frequent nightmares are associated with poor subjective sleep quality, and recent polysomnographic data suggest that nightmare sufferers exhibit impaired sleep continuity during nonrapid eye movement (NREM) sleep. Because disrupted sleep might be related to abnormal arousal processes, the goal of this study was to examine polysomnographic arousal-related activities in a group of nightmare sufferers and a healthy control group.
DESIGN:
Sleep microstructure analysis was carried out by scoring the cyclic alternating pattern (CAP) in NREM sleep and the arousal index in rapid eye movement (REM) sleep on the second night of the polysomnographic examination.
SETTING:
Hospital-based sleep research laboratory.
PARTICIPANTS:
There were 17 in the nightmare (NMs) group and 23 in the healthy control (CTLs) group.
INTERVENTIONS:
N/A.
MEASUREMENTS AND RESULTS:
The NMs group exhibited reduced amounts of CAP A1 subtype and increased CAP A2 and A3 subtypes, as well as longer duration of CAP A phases in comparison with CTLs. Moreover, these differences remained significant after controlling for the confounding factors of anxious and depressive symptoms. The absolute number and frequency of REM arousals did not differ significantly between the two groups.
CONCLUSIONS:
The results of our study indicate that NREM sleep microstructure is altered during nonsymptomatic nights of nightmares. Disrupted sleep in the NMs group seems to be related to abnormal arousal processes, specifically an imbalance in sleep-promoting and arousing mechanisms during sleep.

Fluctuations between sleep and wakefulness: Wake-like features indicated by increased EEG alpha power during different sleep stages in nightmare disorder
Publication year: 2013
URL:
http://www.sciencedirect.com/science/article/pii/S0301051113001609
Abstract/Results: ABSTRACT:
Although a growing body of research indicates that frequent nightmares are related to impaired sleep regulation, the pathophysiology of nightmare disorder is far from being fully understood. We examined the relative spectral power values for NREM and REM sleep separately in 19 individuals with nightmare disorder and 21 healthy controls, based on polysomnographic recordings of the second nights’ laboratory sleep. Nightmare subjects compared to controls exhibited increased relative high alpha (10–14.5 Hz) and fronto-central increases in high delta (3–4 Hz) power during REM sleep, and a trend of increased fronto-central low alpha (7.75–9 Hz) power in NREM sleep. These differences were independent of the confounding effects of waking emotional distress. High REM alpha and low NREM alpha powers were strongly related in nightmare but not in control subjects. The topographical distribution and spectral components of REM alpha activity suggest that nightmare disordered subjects are characterized by wake-like electroencephalographic features during REM sleep.

Abstract/Results: ABSTRACT:
The first-night effect—marked differences between the first- and the second-night sleep spent in a laboratory—is a widely known phenomenon that accounts for the common practice of excluding the first-night sleep from any polysomnographic analysis. The extent to which the first-night effect is present in a participant, as well as its duration (1 or more nights), might have diagnostic value and should account for different protocols used for distinct patient groups. This study investigated the first-night effect on nightmare sufferers (NM; N = 12) and healthy controls (N = 15) using both objective (2-night-long polysomnography) and subjective (Groningen Sleep Quality Scale for the 2 nights spent in the laboratory and 1 regular night spent at home) methods. Differences were found in both the objective (sleep efficiency, wakefulness after sleep onset, sleep latency, Stage-1 duration, Stage-2 duration, slow-wave sleep duration, and REM duration) and subjective (self-rating) variables between the 2 nights and the 2 groups, with a more pronounced first-night effect in the case of the NM group. Furthermore, subjective sleep quality was strongly related to polysomnographic variables and did not differ among 1 regular night spent at home and the second night spent in the laboratory. The importance of these results is discussed from a diagnostic point of view.

Impaired executive functions in subjects with frequent nightmares as reflected by performance in different neuropsychological tasks

Abstract/Results: ABSTRACT:
Nightmare disorder is a prevalent parasomnia characterized by vivid and highly unpleasant dream experiences during night time sleep. The neural background of disturbed dreaming was proposed to be associated with impaired prefrontal and fronto-limbic functioning during REM sleep. We hypothesized that the impaired prefrontal and fronto-limbic functioning in subjects with frequent nightmares would be reflected at the behavioral level during waking tasks as well. 35–35 Subjects with frequent nightmares and matched controls participated in Study 1, involving an Emotional Go/NoGo, an Emotional Stroop task, and a Verbal Fluency task. Nightmare subjects exhibited longer reaction times in the Emotional Go/NoGo and Emotional Stroop tasks. Moreover, they committed more perseveration errors and showed less fluent word generation in the Verbal Fluency task. Nightmare subjects showed an overall slowing irrespective of the valence of the stimuli. While the effects of sleep quality and waking anxiety were associated to these deficits in some cases, these factors could not solely explain the difference between the two groups. In Study 2, 17 subjects with frequent nightmares and 18 controls were compared by a Color-word and an Emotional, block design Stroop task in order to avoid the slow effects of emotional interference potentially caused by previous items. Nightmare subjects were characterized by an overall slowing in the Emotional Stroop task, irrespective of the valence of the stimuli. In the Color-word Stroop task, nightmare subjects were not significantly slower in comparison with controls. Our results suggest that individuals with frequent nightmares are impaired in executive tasks involving the suppression of task-irrelevant semantic representations.

Abstract/Results: ABSTRACT:
Nightmare disorder characterised by recurrent vivid, dysphoric dreams charged with negative emotions is one of the most common sleep problems. While there are two studies about the sleep architecture of nightmare sufferers (NS), as far as we know, the sleep EEG characteristics of them have not been investigated yet. Psychological (Beck Depression and State-Trait Anxiety Inventory) and two-night polysomnographic testing were conducted on 21 university students (10 NS, 11 control) without any prior history of mental or chronic somatic disease. EEG spectra were obtained by using Fast-Fourier Transformation on the second night recordings for REM and NREM separately. We examined the group differences by ANCOVA controlling for the BDI and STAI score. In the nightmare group higher NREM theta (4,25-7,5 Hz) and high sigma (12,75-15 Hz) activities were found mainly at the centroparietal region and the frontal area, respectively. The frontal high sigma activity was correlated significantly with poor sleep assessed by the Groningen Sleep Quality Scale. No
significant differences in REM spectra have been observed. The results suggest that NS differ from controls more in NREM than in REM sleep. The covert REM sleep phenomena might explain the higher theta activity in NS.

Abstract/Results: ABSTRACT:
Aspects of attachment insecurity have gained interest in association of sleep parameters, especially sleep disorders. Most studies are carried out on children using subjective measures of sleep assessed by parents. Little attention is given to REM sleep and dreams in relation to attachment security, which could provide a reasonable association considering the presumed role of REM sleep and dreams in emotion regulation and offline emotional reprocessing. According to some studies, daytime distress and trait anxiety measures are directly associated with sleep features and dream emotions, especially nightmare frequency. If attachment
insecurity is related to dream affects and negative dream frequency is investigated in this study. Results showed significant connections between negative dream affect and attachment categories, which was especially true for preoccupied and fearful attachment, both characterized by high attachment anxiety. According to post hoc testing attachment groups with high attachment anxiety differed significantly from the groups with low attachment anxiety. Attachment anxiety turned out to be connected to nightmare frequency and the intensity of dream affect’s impact on daytime mood. As attachment insecurity is associated with less effective emotional and behavioral responses to stress, poorer coping mechanisms and altered illness behavior, results can be interpreted as the appearance of these qualities in nighttime symptoms. Diminished coping with negative emotions or enhanced negativity in subjects with high attachment anxiety could emerge in form of negative dreaming and higher nightmare frequency. As a consequence, negative dream emotions turn down daytime mood, which is less likely to be regulated by compensatory coping mechanisms. Early traumatization might be a mediator between attachment and nightmares, as both nightmares and insecure attachment are often connected to early trauma of the child. Another possible explanation of the connection between attachment anxiety and negative dreams is rooted in McNamara’s attachment theory of REM sleep, which describes diversified evidence to support the essential role of REM sleep in the conformation and subsistence of attachment behavior.

Abstract/Results: ABSTRACT:
The examination of children’s sleep-related mental experiences presents many significant challenges for researchers investigating the developmental trajectories of human dreaming. In contrast to the well-explored developmental patterns of human sleep, data from dream research are strikingly divergent with highly ambiguous results and conclusions, even though there is plenty of indirect evidence suggesting parallel patterns of development between neural maturation and dreaming. Thus results from studies of children’s dreaming are of essential importance not only to enlighten us on the nature and role of dreaming but to also add to our knowledge of consciousness and cognitive and emotional development. This review summarizes research results related to the ontogeny of dreaming: we critically reconsider the field, systematically compare the findings based on different methodologies, and highlight the advantages and disadvantages of methods, arguing in favor of methodological pluralism. Since most contradictory results emerge in connection with descriptive as well as content related characteristics of young children’s dreams, we emphasize the importance of carefully selected dream collection methods. In contrast nightmare-related studies yield surprisingly convergent results thus provide strong basis for inferences about the connections between dreaming and cognitive emotional functioning. Potential directions for dream research are discussed, aiming to explore the as yet unraveled correlations between the maturation of neural organization, sleep architecture and dreaming patterns.

Abstract/Results: RESULTS:
We aimed to characterize sleep and to test the frontal dysfunction hypothesis of nightmares, as well as to bridge the relationship between the ontogeny of frontal-executive and emotion regulation functions with age-related peculiarities of dreams and nightmares. Nightmare sufferers (NS) were characterized by performance decreases in several executive tasks (Emotional Go/NoGo, Emotional Stroop, Verbal Fluency). Alterations in the sleep architecture (decreases: sleep efficiency, slow wave sleep; increases: wakefulness, arousals, REM sleep), microstructure (increases in A2-microarousals of the cyclic alternating pattern), and qEEG (increased REM sleep 10–14 Hz power and synchronization) were paralleled by a more pronounced first-night effect of NS. Children are more accomplished dreamers with dream narratives closer to adult dream reports than authors of previous laboratory findings described. 4–8 years old children were characterized by a positive correlation of dream report length with slow wave sleep and with performance in the Emotional Stroop test. Negative correlation between the developmental level of executive functioning and dream recall frequency was also established. Our results suggest that NS are characterized by impairments in executive tasks involving the suppression of task-irrelevant semantic representations. Moreover, nightmare-related alterations in sleep architecture and microstructure are characterized by wake-like intrusions disturbing the neurocognitive function of sleep, as well as by emotion-related increases in REM propensity. Children’s dreams should be collected by novel methods, involving their parents. Children’s dreams depend on the maturation of emotion regulation and executive functions.

The functional role of dreaming in emotional processes

Abstract/Results: ABSTRACT:
Dream experience (DE) represents a fascinating condition linked to emotional processes and the human inner world. Although the overlap between REM sleep and dreaming has been overcome, several studies point out that emotional and perceptually vivid contents are more frequent when reported upon awakenings from this sleep stage. Actually, it is well-known that REM sleep plays a pivotal role in the processing of salient and emotional waking-life experiences, strongly contributing to the emotional memory consolidation. In this vein, we highlighted that, to some extent, neuroimaging studies showed that the processes that regulate dreaming and emotional salience in sleep mentation share similar neural substrates of those controlling emotions during wakefulness. Furthermore, the research on EEG correlates of the presence/absence of DE and the results on EEG pattern related to the incorporated memories converged to assign a crucial role of REM theta oscillations in emotional re-processing. In particular, the theta activity is involved in memory processes during REM sleep as well as during the waking state, in line with the continuity hypothesis. Also, the gamma activity seems to be related to emotional processes and dream recall as well as to lucid dreams. Interestingly, similar EEG correlates of DE have been found in clinical samples when nightmares or dreams occur. Research on clinical samples revealed that promoting the rehearsal of frightening contents aimed to change them is a promising method to treat nightmares, and that lucid dreams are associated with an attenuation of nightmares. In this view, DE can defuse emotional traumatic memories when the emotional regulation and the fear extinction mechanisms are compromised by traumatic and frightening events. Finally, dreams could represent a sort of simulation of reality, providing the possibility to create a new scenario with emotional mastery elements to cope with dysphoric items included in nightmares. In addition, it could be hypothesized that the insertion of bizarre items besides traumatic memories might be functional to “impoverish” the negative charge of the experiences.

Title:
Increased heartbeat-evoked potential during REM sleep in nightmare disorder
Publication year: 2019

Abstract/Results: ABSTRACT
Nightmares are characterized by the experience of strong negative emotions occurring mainly during REM sleep. Some people suffer from nightmare disorder, which is defined by the repeated occurrence of nightmares and by significant distress in wakefulness. Yet, whether frequent nightmares relate to a general increase in emotional reactivity or arousal during sleep remains unclear. To address this question, we recorded heartbeat-evoked potentials (HEPs) during wakefulness, NREM and REM sleep in patients with nightmare disorder and healthy participants. The HEP represents a cortical (EEG) response to the heartbeat and indexes brain-body interactions, such as interoceptive processing and intrinsic levels of arousal. HEP amplitude is typically increased during states of high emotional arousal and motivation, and is decreased in depression. Here we compared the amplitude of HEPs between nightmare patients and healthy controls separately during AWAKE, NREM, REM periods, and found higher HEP amplitude in nightmare patients compared to healthy controls over a cluster of frontal regions only during REM sleep. This effect was not paralleled by any group difference in cardiac control measures (e.g. heart rate variability, interbeat interval). These findings corroborate the notion that nightmares are essentially a REM pathology and suggest that increased emotional arousal during REM sleep, as measured by HEP, is a physiological condition responsible for frequent nightmares. This result also supports that HEP may be used as a biomarker of increased emotional and sensory processing during REM sleep in these patients.

Abstract/Results: ABSTRACT:
The aim of this study was to assess whether participants who present more frequently with nightmares or distressing dreams have had traumatic experiences in their childhood and their relationship with current personality traits. Three instruments were administered to a sample of 446 adults from the Argentine population: the Dreams Questionnaire, Negative Childhood Experiences Questionnaire, and an abbreviated version of the Symptoms Assessment. The results showed that participants presented specific dream content, such as hearing voices/music in dreams (88%), lucid dreams (79%), night terrors (64%), evil/demonic presences (61%), and dreams about a traumatic events (40%). The results also showed a correlation between the frequency of dream experiences and parental maltreatment (emotional, sexual, and physical abuse) and a positive and significant correlation between dream recall with propensity for mental health vulnerability symptoms, which confirmed the two main hypotheses. In addition, a gender difference showed that males tended to have greater dream recall compared to females, and females tended to show predominantly more auditory dreams and night terrors compared to males.
