Slow dissolving of emotional distress contributes to hyperarousal

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.

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.

Abstract/Results: ABSTRACT:
BACKGROUND
The mechanisms of hyperarousal, the key symptom of insomnia, have remained elusive. Recently, restless REM sleep emerged as a robust signature of 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.
AIMS
We aimed to investigate whether restless REM sleep impedes overnight distress resolution, and accumulates as hyperarousal.
METHOD
Observational and experimental studies employed psychometrics, EEG and fMRI. We first validated a proxy measure for restless REM sleep, and assessed it in a large sample along with measures of distress dissolving and hyperarousal. We then implemented an internet-protocol to induce self-conscious distress and assessed distress dissipation across 5 consecutive days. The same distress-inducing protocol was used in a MRI scanner while conditioning it to a simultaneously provided odor. The odor was again given during part of the subsequent sleep period, to induce targeted memory reactivation. A second MRI scan of distress induction evaluated how neural correlates of its impact changed overnight.
RESULTS
Of the association between restless REM sleep and hyperarousal, 62.4% was mediated specifically by reduced overnight resolution of emotional distress in insomnia. In people with insomnia, a night's sleep could even increase distress, rather than resolve it. MRI findings indicated activation of the salience network during the induction self-conscious emotions, that ameliorated with sleep but not with a similar interval of being awake.
CONCLUSION
Restless REM sleep interferes with overnight maintenance of balanced salience network activation.

A clinical interpretation of shame regulation in maladaptive perfectionism

Abstract/Results: ABSTRACT
Maladaptive perfectionism, a transdiagnostic personality trait, is associated with depression. Shame has been associated with depressive disorders and to negatively impact its treatment. Interestingly, maladaptive perfectionism and maladaptive shame regulation strategies might be both expressions of an internalizing personality style. We applied forward and backward stepwise linear regression modeling to explain maladaptive perfectionism by association of shame coping styles in a highly powered cross-sectional study of 1436 participants. Maladaptive perfectionism was shown to have significant positive associations with the two internalizing coping styles attacking the self, and withdrawing, and negative associations with adaptive coping. Furthermore, a significant positive interaction effect was shown for the two internalizing coping styles.
Our research shows that participants who adopt maladaptive perfectionism, internalize the pain of shame. Clinically, this is especially relevant during treatment: the patterns of maladaptive perfectionism must come into the open, the client feels exposed and, consistent with his shame regulation style, shame grows. Our research might account for the negative responsiveness of perfectionism to brief therapies for depression: there may not be enough focus on and time for working through the evoked shame.

Haunted by the past: old emotions remain salient in insomnia disorder
Abstract/Results: ABSTRACT
Studies suggest that sleep supports persistent changes in the neuronal representation of emotional experiences such that they are remembered better and less distressful when recalled than when they were first experienced. It is conceivable that sleep fragmentation by arousals, a key characteristic of insomnia disorder, could hamper the downregulation of distress. In this study, we sought further support for the idea that insomnia disorder may involve a lasting deficiency to downregulate emotional distress. We used functional MRI in insomnia disorder (n = 27) and normal sleepers (n = 30) to identify how brain activation differs between novel and relived self-conscious emotions. We evaluated whether brain activity elicited by reliving emotional memories from the distant past resembles the activity elicited by novel emotional experiences more in insomnia disorder than in normal sleepers. Limbic areas were activated during novel shameful experiences as compared to neutral experiences in both normal sleepers and insomnia disorder. In normal sleepers, reliving of shameful experiences from the past did not elicit a limbic response. In contrast, participants with insomnia disorder recruited overlapping parts of the limbic circuit, in particular the dorsal anterior cingulate cortex, during both new and relived shameful experiences. The differential activity patterns with new and old emotions in normal sleepers suggest that reactivation of the long-term memory trace does not recruit the limbic circuit. The overlap of activations in insomnia disorder is in line with the hypothesis that the disorder involves a deficiency to dissociate the limbic circuit from the emotional memory trace. Moreover, the findings provide further support for a role of the anterior cingulate cortex in insomnia.

Restless REM sleep impedes overnight amygdala adaptation
Publication year: 2019

https://www.sciencedirect.com/science/article/pii/S0960982219307614
Abstract/Results: ABSTRACT:
Animal studies show that insufficient silencing of the locus coeruleus (LC) during REM sleep impairs sleep-related brain plasticity. Restless REM sleep, a characteristic of several psychiatric disorders, likely reflects insufficient LC silencing. We investigated whether endogenous REM sleep interruptions interfere with overnight reorganization of limbic circuits in human volunteers with a wide range of insomnia severity, from no insomnia complaints to fulfilling community-sample criteria for insomnia disorder. We induced a self-conscious emotion during two functional MRI sessions and recorded sleep EEG in between. Amygdala reactivity decreased overnight in proportion to the total duration of consolidated REM sleep. Restless REM sleep, in contrast, impeded overnight amygdala adaptation. Using targeted memory reactivation with odors tagged to the self-conscious emotional stimulus, we could experimentally enhance both the favorable effect of consolidated REM sleep and the unfavorable effect of restless REM sleep. The findings reveal a maladaptive type of sleep, providing a target for interventions in mental disorders characterized by restless REM sleep.

Brain structural connectivity network alterations in insomnia disorder reveal a central role of the right angular gyrus
Publication year: 2019
URL:
https://www.sciencedirect.com/science/article/pii/S2213158219303699
Abstract/Results: ABSTRACT:
Insomnia Disorder (ID) is a prevalent and persistent condition, yet its neural substrate is not well understood. The cognitive, emotional, and behavioral characteristics of ID suggest that vulnerability involves distributed brain networks rather than a single brain area or connection. The present study utilized probabilistic diffusion tractography to compare the whole-brain structural connectivity networks of people with ID and those of matched controls without sleep complaints.
Diffusion-weighted images and T1-weighed images were acquired in 51 people diagnosed with ID (21–69 years of age, 37 female) and 48 matched controls without sleep complaints (22–70 years of age, 31 female). Probabilistic tractography was performed to construct the whole-brain structural connectivity network of each participant. Case–control differences in connectivity strength and network efficiency were evaluated with permutation tests.
People with ID showed structural hyperconnectivity within a subnetwork that spread over frontal, parietal, temporal, and subcortical regions and was anchored at the right angular gyrus. The result was robust across different edge-weighting strategies. Moreover, converging support was given by the finding of heightened right angular gyrus nodal efficiency (harmonic centrality) across varying graph density in people with ID. Follow-up correlation analyses revealed that subnetwork connectivity was associated with self-reported reactive hyperarousal.
The findings demonstrate that the right angular gyrus is a hub of enhanced structural connectivity in ID. Hyperconnectivity within the identified subnetwork may contribute to increased reactivity to stimuli and may signify vulnerability to ID.

Publication year: 2020

https://academic.oup.com/sleep/article/43/8/zsaa031/5775301
Abstract/Results: ABSTRACT:
Study Objectives: Suggested neural correlates of insomnia disorder have been hard to replicate. Even the most consistent finding, altered white matter microstructure in the anterior limb of the internal capsule, is based on handful studies. The urge for replicable targets to understand the underlying mechanisms of insomnia made us study white matter fractional anisotropy (FA) across three samples of cases and controls.
Methods: 3-Tesla MRI diffusion tensor imaging data of three independent samples were combined for analysis, resulting in n = 137 participants, of whom 73 were diagnosed with insomnia disorder and 64 were matched controls without sleep complaints. Insomnia severity was measured with the Insomnia Severity Index (ISI). White matter microstructure was assessed with FA. White matter tracts were skeletonized and analyzed using tract-based spatial statistics. We performed a region-of-interest analysis using linear mixed-effect models to evaluate case-control differences in internal capsule FA as well as associations between internal capsule FA and insomnia severity.
Results: FA in the right limb of the anterior internal capsule was lower in insomnia disorder than in controls (beta = -9.76e(-3); SE = 4.17e(-3), p = .034). In the entire sample, a higher ISI score was associated with a lower FA value of the right internal capsule (beta = -8.05e(- 4) FA/ISI point, SE = 2.60e(- 4), p = .008). Ancillary whole brain voxel-wise analyses showed no significant group difference or association with insomnia severity after correction for multiple comparisons.
Conclusions: The internal capsule shows small but consistent insomnia-related alterations. The findings support a circuit-based approach to underlying mechanisms since this tract connects many brain areas previously implicated in insomnia.

Data-driven analysis of EEG reveals concomitant superficial sleep during deep sleep in insomnia disorder

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.

Reduced dynamic functional connectivity between salience and executive brain networks in insomnia disorder
Publication year: 2019

Abstract/Results: Research into insomnia disorder has pointed to large-scale brain network dysfunctions. Dynamic functional connectivity is instrumental to cognitive functions but has not been investigated in insomnia disorder. This study assessed between-network functional connectivity strength and variability in patients with insomnia disorder as compared with matched controls without sleep complaints. Twelve-minute resting-state functional magnetic resonance images and T1-weighed images were acquired in 65 people diagnosed with insomnia disorder (21–69 years, 48 female) and 65 matched controls without sleep complaints (22–70 years, 42 female). Pairwise correlations between the activity time series of 14 resting-state networks and temporal variability of the correlations were compared between cases and controls. After false discovery rate correction for multiple comparisons, people with insomnia disorder and controls did not differ significantly in terms of mean between-network functional connectivity strength; people with insomnia disorder did, however, show less functional connectivity variability between the anterior salience network and the left executive-control network. The finding suggests less flexible interactions between the networks during the resting state in people with insomnia disorder.

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.
