Title:
Wake high-density electroencephalographic spatiospectral signatures of insomnia
Publication year: 2016

http://www.journalsleep.org/ViewAbstract.aspx?pid=30586
Abstract/Results: ABSTRACT:
STUDY OBJECTIVES:
Although daytime complaints are a defining characteristic of insomnia, most EEG studies evaluated sleep only. We used high-density electroencephalography to investigate wake resting state oscillations characteristic of insomnia disorder (ID) at a fine-grained spatiospectral resolution.
METHODS:
A case-control assessment during eyes open (EO) and eyes closed (EC) was performed in a laboratory for human physiology. Participants (n = 94, 74 female, 21–70 y) were recruited through www.sleepregistry.nl: 51 with ID, according to DSM-5 and 43 matched controls. Exclusion criteria were any somatic, neurological or psychiatric condition. Group differences in the spectral power topographies across multiple frequencies (1.5 to 40 Hz) were evaluated using permutation-based inference with Threshold-Free Cluster-Enhancement, to correct for multiple comparisons.
RESULTS:
As compared to controls, participants with ID showed less power in a narrow upper alpha band (11–12.7 Hz, peak: 11.7 Hz) over bilateral frontal and left temporal regions during EO, and more power in a broad beta frequency range (16.3–40 Hz, peak: 19 Hz) globally during EC. Source estimates suggested global rather than cortically localized group differences.
CONCLUSIONS:
The widespread high power in a broad beta band reported previously during sleep in insomnia is present as well during eyes closed wakefulness, suggestive of a round-the-clock hyperarousal. Low power in the upper alpha band during eyes open is consistent with low cortical inhibition and attentional filtering. The fine-grained HD-EEG findings suggest that, while more feasible than PSG, wake EEG of short duration with a few well-chosen electrodes and frequency bands, can provide valuable features of insomnia.

Slow dissolving of emotional distress contributes to hyperarousal
Publication year: 2016

http://www.pnas.org/content/113/9/2538.abstract
Abstract/Results: ABSTRACT:
The mechanisms underlying hyperarousal, the key symptom of insomnia, have remained elusive, hampering cause-targeted treatment. Recently, restless rapid-eye-movement (REM) sleep emerged as a robust signature of sleep in insomnia. Given the role of REM sleep in emotion regulation, we hypothesized that restless REM sleep could interfere with the overnight resolution of emotional distress, thus contributing to accumulation of arousal. Participants (n = 1,199) completed questionnaires on insomnia severity, hyperarousal, self-conscious emotional distress, and thought-like nocturnal mentation that was validated to be a specific proxy for restless REM sleep (selective fragmentation: R = 0.57, P < 0.001; eye movement density: R = 0.46, P < 0.01) in 32 polysomnographically assessed participants. The experience of distress lasting overnight increased with insomnia severity (ß = 0.29, P < 10-23), whereas short-lasting distress did not (ß = -0.02, P = 0.41). Insomnia severity was associated with hyperarousal (ß = 0.47, P < 10-63) and with the thought-like nocturnal mentation that is specifically associated with restless REM sleep (ß = 0.31, P < 10-26). Structural equation modeling showed that 62.4% of the association between these key characteristics of insomnia was mediated specifically by reduced overnight resolution of emotional distress. The model outperformed all alternative mediation pathways. The findings suggest that restless REM sleep reflects a process that interferes with the overnight resolution of distress. Its accumulation may promote the development of chronic hyperarousal, giving clinical relevance to the role of REM sleep in emotion regulation in insomnia, depression, and posttraumatic stress disorder.

Title: More severe insomnia complaints in people with stronger long-range temporal correlations in wake resting-state EEG
Publication year: 2016
URL:
http://journal.frontiersin.org/article/10.3389/fphys.2016.00576/full
Abstract/Results: ABSTRACT:
The complaints of people suffering from Insomnia Disorder (ID) concern both sleep and daytime functioning. However, little is known about wake brain temporal dynamics in people with ID. We therefore assessed possible alterations in Long-Range Temporal Correlations (LRTC) in the amplitude fluctuations of band-filtered oscillations in electroencephalography (EEG) recordings. We investigated whether LRTC differ between cases with ID and matched controls. Within both groups, we moreover investigated whether individual differences in subjective insomnia complaints are associated with LRTC. Resting-state high-density EEG (256-channel) was recorded in 52 participants with ID and 43 age- and sex-matched controls, during Eyes Open (EO) and Eyes Closed (EC). Detrended fluctuation analysis was applied to the amplitude envelope of band-filtered EEG oscillations (theta, alpha, sigma, beta-1, beta-2) to obtain the Hurst exponents (H), as measures of LRTC. Participants rated their subjective insomnia complaints using the Insomnia Severity Index (ISI). Through general linear models, we evaluated whether H, aggregated across electrodes and frequencies, differed between cases and controls, or showed within-group associations with individual differences in ISI. Additionally, we characterized the spatio-spectral profiles of group differences and associations using non-parametric statistics. H did not differ between cases with ID and controls in any of the frequency bands, neither during EO nor EC. During EO, however, within-group associations between H and ISI indicated that individuals who experienced worse sleep quality had stronger LRTC. Spatio-spectral profiles indicated that the associations held most prominently for the amplitude fluctuations of parietal theta oscillations within the ID group, and of centro-frontal beta-1 oscillations in controls. While people suffering from insomnia experience substantially worse sleep quality than controls, their brain dynamics express similar strength of LRTC. In each group, however, individuals experiencing worse sleep quality tend to have stronger LRTC during eyes open wakefulness, in a spatio-spectral range specific for each group. Taken together, the findings indicate that subjective insomnia complaints involve distinct dynamical processes in people with ID and controls. The findings are in agreement with recent reports on decreasing LRTC with sleep depth, and with the hypothesis that sleep balances brain excitability.

Title:
Overnight worsening of emotional distress indicates maladaptive sleep in insomnia

Abstract/Results: ABSTRACT:
Study Objectives Mechanisms underlying the distress of hyperarousal in people with insomnia remain enigmatic. We investigated whether insomnia impedes the overnight adaptation to emotional distress.
Methods We induced the distressful self-conscious emotion of shame four times across three consecutive days by exposing 64 participants to their often embarrassingly out-of-tune singing, recorded earlier during a Karaoke session. Perceived physical, emotional, and social distress was assessed with the Experiential Shame Scale.
Results Compared to exposures followed by wakefulness, exposures followed by sleep resulted in overnight relief of physical component of shame in normal sleepers, but in a striking opposite overnight worsening in people with insomnia.
Conclusions Our findings are the first to experimentally show that the benefits of sleep are not only lost when sleep is poor; people with insomnia experience a maladaptive type of sleep that actually aggravates physically perceived distress. Maladaptive sleep could shed new light on posttraumatic stress disorder (PTSD) and on diurnal mood fluctuation and the counterintuitive favorable effects of sleep deprivation in depression.

Unbalanced resting-state networks activity in psychophysiological insomnia
Publication year: 2017

Abstract/Results: ABSTRACT:
Psychophysiological insomnia (PI) is a clinical condition characterized by sleep-related disturbing cognitive activity and biased self-related information processing. This hypothetical cognitive arousal has been hypothesized to be associated with overactivation within different brain areas and networks, especially when individuals are at rest, e.g., in the absence of any attention-demanding task. In this study, we carried out a resting-state fMRI experiment aimed at investigating activity of the different resting-state networks in PI. Our pool of participants was compound of 5 PI patients and 5 sex- and age-matched healthy controls recruited from the community. Participants from both groups also completed a set of self-report measures, including the sleep diary, Insomnia Severity Index (ISI), dysfunctional beliefs and attitudes about sleep (DBAS-30), and the World Health Organization Quality of Life Measure (WHOQOL-Bref). Our results showed that insomnia patients presented altered activation in the default-mode network (DMN), visual and auditory networks, and bilateral fronto-parietal networks. In the DMN, the patients presented a pattern of both decreased (right superior frontal gyrus, left medial frontal gyrus, and right middle temporal gyrus) and increased activation (left superior frontal gyrus, left anterior and posterior cingulate, right precuneus, left cingulate gyrus, and left middle temporal gyrus). Our findings on unbalanced resting-state networks in PI, with special emphasis on the DMN, may lay grounds to better understanding of the cognitive arousal experienced by PI patients and might help to further improve the clinical management of insomnia.

Increased hippocampal-prefrontal functional connectivity in insomnia
Publication year: 2019

https://www.sciencedirect.com/science/article/pii/S1074742718300194
Abstract/Results: ABSTRACT:
Insomnia Disorder (ID) is the second-most common mental disorder and has a far-reaching impact on daytime functioning. A meta-analysis indicates that, of all cognitive domains, declarative memory involving the hippocampus is most affected in insomnia. Hippocampal functioning has consistently been shown to be sensitive to experimental sleep deprivation. Insomnia however differs from sleep deprivation in many aspects, and findings on hippocampal structure and function have been equivocal. The present study used both structural and resting-state functional Magnetic Resonance Imaging in a larger sample than previously reported to evaluate hippocampal volume and functional connectivity in ID. Included were 65 ID patients (mean age = 48.3 y ± 14.0, 17 males) and 65 good sleepers (mean age = 44.1 y ± 15.2, 23 males). Insomnia severity was assessed with the Insomnia Severity Index (ISI), subjective sleep with the Consensus Sleep Diary (CSD) and objective sleep by two nights of polysomnography (PSG). Seed-based analysis showed a significantly stronger connectivity of the bilateral hippocampus with the left middle frontal gyrus in ID than in controls (p = .035, cluster based correction for multiple comparisons). Further analyses across all participants moreover showed that individual differences in the strength of this connectivity were associated with insomnia severity (ISI, r = .371, p = 9.3e-5) and with subjective sleep quality (CSD sleep efficiency, r = -.307, p = .009) (all p FDR-corrected). Hippocampal volume did not differ between ID and controls. The findings indicate more severe insomnia and worse sleep quality in people with a stronger functional connectivity between the bilateral hippocampus and the left middle frontal gyrus, part of a circuit that characteristically activates with maladaptive rumination and deactivates with sleep.

Abstract/Results:
ABSTRACT:
BACKGROUND
Sleep and interoception are important regulating processes of physiological homeostasis and of consciousness. However, few studies have investigated the relationship between them. People with insomnia chronically experience their sleep as conscious wakefulness, which we hypothesize could involve interoception-related neural dysfunctions.
AIMS
By incorporating EEG, neuroimaging, and questionnaire data, we aim to establish direct links between interoception and the experience of (un)consciousness during sleep.
METHOD
Measures of brain network activity including EEG microstate properties and BOLD functional connectivity variability, as well as brain connectivity networks derived from diffusion MRI tractography, were compared between people with insomnia and people without sleep complaints. Self-reported measures were collected in a community-based sample and used to investigate the relationship between somatic complaints and insomnia severity.
RESULTS
The mean duration of a particular class of EEG microstates previously linked to salience network activity is reduced in people with insomnia. Functional connectivity variability between the anterior salience network and the left executive control network is reduced in people with insomnia. People with insomnia show brain structural hyperconnectivity in a subnetwork anchored at the right angular gyrus. Poor sleep and somatic complaints mutually reinforce each other while their relationship is modulated by habitual insomnia severity.
CONCLUSIONS
There is a tight relationship between sleep and interoception. Experience of consciousness during sleep involves aberrant dynamics of the salience network, a key network for interoception

Brain mechanisms of insomnia: new perspectives on causes and consequences
Publication year: 2020

https://journals.physiology.org/doi/pdf/10.1152/physrev.00046.2019
Abstract/Results: ABSTRACT:
While insomnia is the second most common mental disorder, progress in our understanding of underlying neurobiological mechanisms has been limited. The present review addresses the definition and prevalence of insomnia and explores its subjective and objective characteristics across the 24-hour day. Subsequently, the review extensively addresses how the vulnerability to develop insomnia is affected by gene variants, early life stress and major life events and brain structure and function. Further supported by the clear mental health risks conveyed by insomnia, the integrated findings suggest that the vulnerability to develop insomnia could rather be found in brain circuits regulating emotion and arousal than in circuits involved in circadian and homeostatic sleep regulation. Finally, a testable model is presented. The model proposes that in people with a vulnerability to develop insomnia, the locus coeruleus is more sensitive to - or receives more input from - the salience network and related circuits, even during REM sleep, when it should normally be sound asleep. This vulnerability may ignite a downwards spiral of insufficient overnight adaptation to distress, resulting in accumulating hyperarousal which in turn impedes restful sleep and moreover increases the risk of other mental health adversity. Sensitized brain circuits are likely to be subjectively experienced as "sleeping with one eye open". The proposed model opens up the possibility for novel intervention studies and animal studies, thus accelerating the ignition of a neuroscience of insomnia, which is direly needed for better treatment.

Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Data-driven analysis of EEG reveals concomitant superficial sleep during deep sleep in insomnia disorder
Publication year: 2019
URL:
https://www.frontiersin.org/articles/10.3389/fnins.2019.00598/full
Abstract/Results: ABSTRACT:
Study Objectives: The subjective suffering of people with Insomnia Disorder (ID) is insufficiently accounted for by traditional sleep classification, which presumes a strict sequential occurrence of global brain states. Recent studies challenged this presumption by showing concurrent sleep-and wake-type neuronal activity. We hypothesized enhanced co-occurrence of diverging EEG vigilance signatures during sleep in ID.
Methods: Electroencephalography (EEG) in 55 cases with ID and 64 controls without sleep complaints was subjected to a Latent Dirichlet Allocation topic model describing each 30 s epoch as a mixture of six vigilance states called Topics (T), ranked from N3-related T1 and T2 to wakefulness-related T6. For each stable epoch we determined topic dominance (the probability of the most likely topic), topic co-occurrence (the probability of the remaining topics), and epoch-to-epoch transition probabilities.
Results: In stable epochs where the N1-related T4 was dominant, T4 was more dominant in ID than in controls, and patients showed an almost doubled co-occurrence of T4 during epochs where the N3-related T1 was dominant. Furthermore, patients had a higher probability of switching from T1- to T4-dominated epochs, at the cost of switching to N3-related T2-dominated epochs, and a higher probability of switching from N2-related T3- to wakefulness-related T6-dominated epochs.
Conclusion: Even during their deepest sleep, the EEG of people with ID express more N1-related vigilance signatures than good sleepers do. People with ID are moreover more likely to switch from deep to light sleep and from N2 sleep to wakefulness. The findings suggest that hyperarousal never rests in ID.

A network analysis of self-reported sleep bruxism in the Netherlands sleep registry: its associations with insomnia and several demographic, psychological, and life-style factors
Publication year: 2022

https://www.sciencedirect.com/science/article/pii/S1389945722000946
Abstract/Results: Objectives
To investigate the association between self-reported sleep bruxism and insomnia and their potential risk factors (eg, depression and anxiety), and to construct a network model with all these factors.
Methods
We recruited 2251 participants from the Netherlands Sleep Registry. All participants completed questionnaires on self-reported sleep bruxism, insomnia, depression, anxiety, smoking frequency, and alcohol and caffeine consumption. The associations between self-reported sleep bruxism and other variables were analyzed by univariate analysis, multivariate logistic regression, and network analysis.
Results
Although univariate analysis showed that there was a positive association between sleep bruxism and insomnia (P < 0.001), this association disappeared in the multivariate logistic regression model (P = 0.258). However, multivariate logistic regression did show an association between self-reported sleep bruxism and anxiety (OR = 1.087, 95% CI 1.041–1.134). The network model showed that there was no direct link between self-reported sleep bruxism and insomnia. However, there was an indirect link between self-reported sleep bruxism and insomnia via anxiety.
Conclusions
Although self-reported sleep bruxism has no direct association with insomnia, anxiety is a bridging factor between these variables.

Abstract/Results: Cognitive therapy (CT) and behavior therapy (BT) are both effective for insomnia. In this study we applied Network Intervention Analysis to investigate specific effects of CT and BT on outcomes and process measures. The analysis was based on a randomized controlled trial comparing CT (n = 65), BT (n = 63) and cognitive behavioral therapy for insomnia (n = 60; not included in this study). In the first networks, the separate items of the Insomnia Severity Index and sleep efficiency were included. In the second networks, the pre-specified process measures for BT and CT, sleep efficiency, and the sum-score of the Insomnia Severity Index were included. At the different time points, we found CT-effects on worry, impaired quality of life, dysfunctional beliefs, and monitoring sleep-related threats, and BT-effects on sleep efficiency, difficulty maintaining sleep, early morning awakening, time in bed, sleep incompatible behaviors and bed- and rise time variability. These observed effects of CT and BT were consistent with their respective theoretical underpinnings. This study provided new information on the mechanisms of change in CT and BT. In the future, this may guide us to the most effective treatment modules or even subsets of interventions.

From childhood trauma to hyperarousal in adults: The mediating effect of maladaptive shame coping and insomnia
Publication year: 2023
URL:
https://www.frontiersin.org/articles/10.3389/fnhum.2023.990581/full
Abstract/Results: ABSTRACT:
Introduction:
A new line of insomnia research focuses on the developmental trajectories from early live stress to insomnia in adulthood. Adverse childhood experiences (ACE's) might create a vulnerability for later maladaptive coping with distress, as seen in chronic hyperarousal or insomnia. In an functional magnetic resonance imaging (fMRI) study, failure to dissociate the neurobiological components of shame from autobiographical shameful memories in insomnia was reflected by continued activation of the dorsal anterior cingulate cortex (dACC), which may be a result of maladaptive coping in the wake of ACE's. Following up on that study, the current pilot study explores the relation between ACE's, shame coping-styles, adult insomnia, hyperarousal, and neurobiology of autobiographical memory.
Methods:
We used existing data (N = 57) from individuals with insomnia (N = 27) and controls (N = 30), and asked these participants to complete the childhood trauma questionnaire (CTQ). Two structural equation models were used to test the hypotheses that shame-coping styles and insomnia symptom severity mediate the association between ACE's and (1) self-rated hyperarousal symptoms and (2) dACC activation to recall of autobiographical memories.
Results:
For the association between ACE's and hyperarousal, there was a significant mediation of shame-coping style (p < 0.05). This model also indicated worse shame coping with more ACE's (p < 0.05) and worse insomnia symptoms with more ACES's (p < 0.05), but no association between shame coping and insomnia symptoms (p = 0.154). In contrast, dACC activation to recall of autobiographical memories could only be explained by its direct association with ACE's (p < 0.05), albeit that in this model more ACE's were also associated with worse insomnia symptoms.
Discussion:
These findings could have an implication for the approach of treatment for insomnia. It could be focused more on trauma and emotional processing instead of conventional sleep interventions. Future studies are recommended to investigate the relationship mechanism between childhood trauma and insomnia, with additional factors of attachment styles, personality, and temperament.

Sleep reactivity mediates the relationship between sensory-processing sensitivity and insomnia symptoms severity: A cross-sectional correlational study
Publication year: 2024
URL:
https://doi.org/10.1002/smi.3297
Abstract/Results: ABSTRACT:
Sensory-processing sensitivity (SPS) is a temperamental trait that describes individual differences in sensitivity to environmental stimuli. Previous studies have shown that highly sensitive individuals are more vulnerable to stress and to sleep-related difficulties. In light of this evidence, we hypothesized that SPS is associated with an increase in insomnia symptoms and that this correlation would be mediated by increased perceived stress and sleep reactivity. To test this hypothesis, we conducted a cross-sectional study on 358 adults who completed a survey that included self-report measures of sensitivity, perceived stress, sleep reactivity, and insomnia symptoms. Correlation analysis revealed that SPS was positively related to both stress-related and sleep-related variables. We then conducted a mediation analysis, which revealed that SPS was positively related to insomnia symptoms and that this relationship was fully mediated by sleep reactivity but not mediated at all by perceived stress. The current findings suggest that sleep reactivity may contribute to the development of insomnia symptoms in highly sensitive individuals. Therefore, these results suggests that sleep reactivity should be assessed in highly sensitive individuals and that it could be important to evaluate and further study this relationship.
