Disturbed dreaming and sleep quality: Altered sleep architecture in subjects with frequent nightmares
Publication year: 2012

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.

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

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.

Title:
REM sleep EEG theta activity is a negative correlate of attachment anxiety
Publication year: 2011
URL:
http://www.frontiersin.org/alerts/pdf/behavioral_neuroscience/EBBS2011_abstracts.pdf
Abstract/Results: ABSTRACT:
INTRODUCTION:
Several behavioural correlates of EEG theta activity were reported previously. Some of these correlates
were shown to be trait-like in nature belonging to the affective domain. Frontal theta activity measured during wakeful resting conditions was found to be a negative correlate of anxiety-related measures mainly. However, knowledge on the trait-like affective correlates of REM sleep theta activity is sparse. Based on the intimate relationship between REM sleep and attachment, as well as on the neurobiology of this sleep state we hypothesize that REM sleep frontal theta activity is negatively correlated with measures of attachment anxiety (AAn). As Heart Rate Variability (HRV) as an indicator of the sympatovagal balance was shown to be related to theta activity, we also hypothesized that REM sleep HRV is related to both theta activity and AAn.
METHODS:
35 subjects (20 men, Mage=31.6 years) slept two consecutive nights in the sleep laboratory. Polysomnography covered EEG, EOG, and ECG. Power spectra of whole second night NREM and REM sleep
EEG as well as spectral HRV measures of the ECG in NREM and REM sleep were calculated. Subjects filled
the Relationship Scales Questionnaire measuring adult attachment along the dimensions of AA and attachment avoidance (AAv). Pearson correlations between log-normalized 0.25 Hz wide EEG power bins and attachment, between log-normalized EEG power and HRV, as well as between HRV and attachment were calculated.
RESULTS:
Significant negative correlations between REM sleep EEG power and AAn were observed at frequencies pertaining to the theta range (4.75-7.5 Hz) in the fronto-central and temporal regions. These correlations were specific to REM sleep as NREM sleep theta EEG power was found to be uncorrelated with AAn. The hypothesized correlations between REM sleep theta EEG power and HRV, or AAn and HRV were not supported by our data. Unpredicted correlations were negative between AAn and REM sleep frontal beta (12.25-20.25 Hz) power, and positive between AAv and NREM sleep alpha/sigma (8-13 Hz) power.
DISCUSSION:
Frontal theta activity and HRV are unrelated, perhaps physiologically uncoupled during REM sleep. REM sleep theta EEG, but not HRV is negatively associated with questionnaire measures of AAn.

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:
OBJECTIVES:
Idiopathic nightmare disorder, which affects 2–8% of the population, is a distinct diagnostic category in the International Classification of Sleep Disorders (2nd edition) and the Diagnostic and Statistical Manual of Mental Disorders as well. However, the characteristic sleep profile of nightmare subjects (NMs) has rather
been under-researched. Our goal is to obtain a comprehensive picture of the sleep of NMs by means of spectral electroencephalographic (EEG) analyses which can provide valuable insights into the underlying pathophysiology.
METHODS:
Thirty-five university students without any prior history of mental or chronic somatic disease (17 NMs and 18 controls) went through standard two-night polysomnographic examination (with 19 EEG channels) in our sleep laboratory. Psychometric testing was also conducted including the State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI). EEG spectra were obtained by using Fast-Fourier Transformation of the second night recordings for rapid-eye movement (REM) and non-rapid eye-movement (NREM) sleep separately. We also computed the spectra of the first 4 sleep cycles distinctly in order to understand better sleep dynamics. To control the individual differences in the amplitude of power spectral
density, relative EEG spectra were calculated for 6 frequency bands (delta, theta, alpha, sigma, beta, gamma).
RESULTS:
Regarding all night data we compared the two groups by covariance analysis with STAI and BDI as covariates. The nightmare group was characterised by marginally (P < 0.10) lower frontal delta (1.25–4 Hz), as well as significantly (P < 0.05) higher fronto-central theta (4.25–7.5 Hz) and alpha (7.75–10.25 Hz) NREM activity compared to controls. The separate analysis of sleep cycles revealed that the reduced delta activity is characteristic for the 1st, while the increased theta for the 1st and the 4th sleep periods in NMs. Higher alpha activity was found mainly in the 4th sleep cycle.
CONCLUSIONS:
Our results provide evidence that NMs, even if they did not experience negative dreams, differ from controls in their sleep EEG spectra, mostly regarding NREM sleep. Lower delta activity indicates disrupted sleep which may be associated with impaired executive functions in NMs, whereas higher alpha activity in the 4th sleep cycle may be the sign of hyperarousal later in the night. Moreover, the covert REM sleep phenomena might explain the higher theta activity in NMs.

Is dreaming merely a cognitive performance? Analysis of the content and narrative structure of children’s dreams
Publication year: 2012

http://www.cecog.eu/absbook_ducog2012.pdf
Abstract/Results: ABSTRACT:
Inspired mainly by the longitudinal studies of Foulkes the mainstream of developmental psychology considers dreaming a cognitive performance deriving it solely from children’s cognitive abilities. In contrast, the current neurocognitive approaches see the function of REM sleep and dreaming in the consolidation of
emotional memories and in affective regulation.
This study investigates the ontogeny of dreaming, evaluates the frequency, content and narrative structure of dreams together with the cognitive and affective development in children.
In our content analysis we followed the rules described by Foulkes, but the method of dream collection was fundamentally different: instead of interviews after awakening from sleep in the laboratory, over 6 weeks children would report their dreams at home to their pre-trained parents in the form of tape-recorded dream-diaries based on provided questionnaires.
The initial content analysis (n=12, age=4-8 years) revealed differences to earlier results: dreams are longer in every age group compared to the previous findings, selfrepresentation is more frequent (79%), movement (84%) and living emotions (43%) are common in the dream experience; furthermore the number of dream reports does not change significantly with age (one dream per week in all age groups).
The current study is a part of a bigger research project, which aims to widen our knowledge about this seldom investigated field of developmental studies and dream science - evaluating it in a new, emotional development-centered context and using different methodology.

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.

Content analysis of 4 to 8 year-old children’s dream report

Abstract/Results: ABSTRACT:
The role of dreaming in childhood and in adulthood are still equally enigmatic fields yet to be fully explored. However, while there is a consensus at least about the typical content and formal characteristics of adult dream reports, these features are still a matter of debate in the case of young children. Longitudinal developmental laboratory studies concluded that preschoolers' dreams usually depict static images about mostly animals and body states of the dreamer but they basically lack the active representation of the self, human characters, social interactions, dream emotions and motion imagery. Due to methodological arguments these results became the reference points in the literature of developmental dream research, in spite of the significantly different results of numerous recent and relevant studies using extra-laboratory settings. This study aims to establish a methodologically well-controlled and valid way to collect children's dreams for a representative period of time in a familiar home setting to serve as a comparison to the laboratory method. Pre trained parents acted as interviewers in the course of a 6 week-period of dream collection upon morning awakenings. Our results suggest that even preschoolers are likely to represent their own self in an active role (70%) in their mostly kinematic (82%) dream narratives. Their dream reports contain more human, than animal characters (70 and 7% of all dream characters respectively), and social interactions, self-initiated actions, and emotions are usual part of these dreams. These results are rather similar to those of recent extra-laboratory studies, suggesting that methodological issues may strongly interfere with research outcomes especially in the case of preschoolers' dream narratives. We suggest that nighttime awakenings in the laboratory setting could be crucial in understanding the contradictory results of dream studies in case of young children.

Emotion regulation as reflected in children’s dreams – A developmental test of the neurocognitive dream theory
Publication year: 2016

http://akademiai.com/doi/abs/10.1556/0406.17.2016.2.5
Abstract/Results: ABSTRACT:
INTRODUCTION
Although REM sleep plays an important role in neural maturation, developmental aspects of dream research are relatively neglected compared to studies focusing on adults. Adult research found that REM sleep and dreams take certain roles in emotional adaptation, including the processing of emotional events, consolidation of emotional memories and the downregulation of reactions to dysphoric stimuli. These findings, however, are rarely discussed in a developmental perspective.
AIMS
We aim to test the neurocognitive dream theory developed by Nielsen and Levine (2007) by investigating the associations among abilities of waking emotional processing, behavioral manifestations of emotional problems and the emotional aspects of dreaming in children.
METHODS
We analyzed 349 dream reports of 40 children between the ages of 4 to 8 years. Dream emotions, emotional dream quality and the dreams’ effect on daytime’s mood were self-reported by the children. Wakeful emotional processing is measured by the Emotional Stroop Test for children, and emotional–behavioral problems were assessed by the parent version of the Strength and Difficulties Questionnaire (SDQ).
RESULTS
Results show that negative dream quality and the dreams’ effect on daytime mood are associated with negative emotional adaptation measured by the SDQ (t = .25, p = .031, t = .24, p = .041 respectively). Children with more emotional problems reported more dreams (t = .32, p = .004). Interestingly, we could not find relationship between dream emotions and waking emotional development measures.
CONCLUSION
Results support psychological models of dreaming assuming a role of dreams in emotional regulation and provide partial support for the plausibility of Levin and Nielsen’s neurocognitive theory in a developmental context. Further studies on emotional development and dreaming are needed to gain more insight in the generalizability of the connection between emotional processing during wakeful functioning and REM sleep.

Sleep spindles and intelligence in early childhood – Developmental and trait-dependent aspects
Publication year: 2016
URL:
http://psycnet.apa.org/record/2016-56613-007
Abstract/Results: ABSTRACT:
Sleep spindles act as a powerful marker of individual differences in cognitive ability. Sleep spindle parameters correlate with both age-related changes in cognitive abilities and with the age-independent concept of IQ. While some studies have specifically demonstrated the relationship between sleep spindles and intelligence in young children, our previous work in older subjects revealed sex differences in the sleep spindle correlates of IQ, which was never investigated in small children before. We investigated the relationship between age, Raven Colored Progressive Matrices (CPM) scores and sleep spindles in 28 young children (age 4-8 years, 15 girls). We specifically investigated sex differences in the psychometric correlates of sleep spindles. We also aimed to separate the correlates of sleep spindles that are because of age-related maturation from other effects that reflect an age-independent relationship between sleep spindles and general intelligence. Our results revealed a modest positive correlation between fast spindle amplitude and age. Raven CPM scores positively correlated with both slow and fast spindle amplitude, but this effect remained a tendency in males and vanished after correcting for the effects of age. Age-corrected correlations between Raven CPM scores and both slow and fast spindle amplitude were only significant in females. Overall, our results show that in male children sleep spindles are a maturational marker, but in female children they indicate trait-like intelligence, in line with previous studies in adolescent and adult subjects. Thalamocortical white matter connectivity may be the underlying mechanism behind both higher spindle amplitude and higher intelligence in female, but not male subjects.

Abstract/Results: ABSTRACT:
The development of dreaming and its association with brain maturation and cognitive development are rarely studied in spite of adult studies showing a close relationship between dreaming and cognitive functioning. In order to bridge this gap in the literature we aimed to depict the associations between individual differences in neurocognitive maturation and the formal and content related characteristics of children’s dream reports. We analyzed the dream reports of 40 children between the ages of 4 to 8 years. Specific dream content categories, found to change significantly throughout development, were correlated with cognitive performance. To measure the latter we used neuropsychological tests (a modified version of the Fruit Stroop Test and Emotional Stroop Test for Children, and the Attention Network Test [ANT]) and intelligence tests (subscales of the Wechsler Intelligence Scale for Children [WISC–IV], and the Raven’s Colored Progressive Matrices [CPM]). Results suggest that the dreamer’s presence in their dreams (manifested in activities, interactions, self-effectiveness, willful effort, and cognitive reflections) indicates more effective executive control in waking life. The quality and content of these activities and interactions are correlated with the child’s capacities of emotional processing. Contrary to previous findings dream bizarreness and dream recall frequency were not associated with any cognitive indicators. Although in adult dream research the continuity of waking and dreaming cognition has been well-studied, our work is 1 of the first to explore the connection between children’s cognitive maturation and dreaming.

Abstract/Results: ABSTRACT:
Features of sleep were shown to reflect aging, typical sex differences and cognitive abilities of humans. However, these measures are characterized by redundancy and arbitrariness. Our present approach relies on the assumptions that the spontaneous human brain activity as reflected by the scalp-derived electroencephalogram (EEG) during non-rapid eye movement (NREM) sleep is characterized by arrhythmic, scale-free properties and is based on the power law scaling of the Fourier spectra with the additional consideration of the rhythmic, oscillatory waves at specific frequencies, including sleep spindles. Measures derived are the spectral intercept and slope, as well as the maximal spectral peak amplitude and frequency in the sleep spindle range, effectively reducing 191 spectral measures to 4, which were efficient in characterizing known age-effects, sex-differences and cognitive correlates of sleep EEG. Future clinical and basic studies are supposed to be significantly empowered by the efficient data reduction provided by our approach.
