J Oral Rehabil 2024; 51:110-116. [PMID: 36790219 DOI: 10.1111/joor.13430] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 12/29/2022] [Accepted: 01/23/2023] [Indexed: 02/16/2023]
Abstract
BACKGROUND Sleep bruxism (SB) occurring during No-REM (nREM) sleep and increase in microarousals per hour have been described in adults, but not in children. OBJECTIVE To assess the correlation between sleep architecture and masseter muscle activity related to sleep bruxism (SB/MMA) in children. MATERIALS AND METHODS Forty-three children aged 7-12 years (mean age: 9.4 ± 1.3) with confirmed SB underwent a two-night polysomnographic (PSG) study in a sleep laboratory, for accommodation (first night) and data collection (second night). Data on sleep architecture (total sleep duration (TSD), sleep efficiency (SE), sleep onset latency (SOL), REM and nREM sleep duration and proportion and microarousals/hour during REM and nREM sleep) and episodes/hour of SB/MMA were recorded. Single and multiple-variable linear regression analyses were performed to assess the correlation between data on sleep architecture (predictors) and SB/MMA (dependent variable). RESULTS Shorter TSD, REM and nREM stage 1 sleep duration, longer SOL and more microarousals/hour during REM and nREM sleep were found to be positive predictors of SB/MMA in children in the multiple-variable regression analysis (R2 = 0.511). CONCLUSION Within the limitations of this study, it can be concluded that SB/MMA is correlated with altered sleep architecture in children (shorter total sleep duration (TSD), shorter nREM and REM sleep and higher microarousals during REM and nREM sleep). Nevertheless, the clinical significance of these findings need to be demonstrated in future studies.

Abstract
Depression is associated with general sleep disturbance and abnormalities in sleep physiology. For example, compared with control subjects, depressed patients exhibit lower sleep efficiency, longer rapid eye movement (REM) sleep duration, and diminished slow-wave activity during non-REM sleep. A separate literature indicates that depression is also associated with many distinguishing memory characteristics, including emotional memory bias, overgeneral autobiographical memory, and impaired memory suppression. The sleep and memory features that hallmark depression may both contribute to the onset and maintenance of the disorder. Despite our rapidly growing understanding of the intimate relationship between sleep and memory, our comprehension of how sleep and memory interact in the aetiology of depression remains poor. In this narrative review, we consider how the sleep signatures of depression could contribute to the accompanying memory characteristics.

Abstract
Short and long nightly sleep durations are associated with anxiety and depression symptoms among adolescents. However, studies have not used recommended hours of nightly sleep or focused on sleep patterns across weekdays and weekends in examining links with anxiety and depression symptoms. The present study included 709 adolescents in Grade 11 (402 females; 307 males) who self-reported hours of sleep on weeknights and weekends and anxiety and depression symptoms. Using the recommended 8-10 h to define average nightly sleep for adolescents, sleep patterns across weekdays and weekends were categorised into seven classes: short stable, short increasing, average decreasing, average stable, average increasing, long decreasing, and long stable. Relative to average stable sleepers, short stable, short increasing, and long stable sleepers had significantly higher anxiety and depression. Adolescents require 8-10 h of sleep on weeknights, regardless of weekends, for optimal emotional wellbeing.

Bidirectional associations of physical activity, sleep, and self-reported mental health in young adults participating in an online wellness intervention during the COVID-19 pandemic. Front Public Health 2023; 11:1168702. [PMID: 37325310 PMCID: PMC10264583 DOI: 10.3389/fpubh.2023.1168702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 05/15/2023] [Indexed: 06/17/2023] Open
Abstract
Purpose The purpose of this study was to examine the bidirectional associations of physical activity (PA), sleep, and mental health in young adults participating in an online wellness intervention from October 2021 to April 2022. Methods Participants were a sample of undergraduate students from one US university (N = 89; 28.0% freshman; 73.0% female). The intervention was a 1-h health coaching session that was delivered either once or twice by peer health coaches on Zoom during COVID-19. The number of coaching sessions was determined by random allocation of participants to experimental groups. Lifestyle and mental health assessments were collected at two separate assessment timepoints after each session. PA was assessed using the International Physical Activity Questionnaire-Short Form. Weekday and weekend sleep were assessed by two one-item questionnaires and mental health was calculated from five items. Cross-lagged panel models (CLPMs) examined the crude bidirectional associations of PA, sleep, and mental health across four-time waves (i.e., T1 through T4). To control for individual unit effects and time-invariant covariates, linear dynamic panel-data estimation using maximum likelihood and structural equation modeling (ML-SEM) was also employed. Results ML-SEMs showed that mental health predicted future weekday sleep (β = 0.46, p < 0.001) and weekend sleep predicted future mental health (β = 0.11, p = 0.028). Although CLPMs showed significant associations between T2 PA and T3 mental health (β = 0.27, p = 0.002), no associations were observed when unit effects and time-invariant covariates were accounted for. Conclusion Self-reported mental health was a positive predictor of weekday sleep and weekend sleep positively predicted mental health during the online wellness intervention.

Minority stress and sleep: How do stress perception and anxiety symptoms act as mediators for sexual minority men? Sleep Health 2023; 9:136-143. [PMID: 36697318 DOI: 10.1016/j.sleh.2023.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 12/12/2022] [Accepted: 01/02/2023] [Indexed: 01/25/2023]
Abstract
OBJECTIVES Sexual minority men experience worse sleep than heterosexuals. Little is known about how minority stress may account for these differences. Therefore, the aims of this study are to (1) understand the relationship between minority stress and sleep disturbance in a sample of sexual minority men, and (2) test whether these relationships are mediated by generalized anxiety symptoms and perception of stress. METHODS In 2020, 239 sexual minority men were recruited to complete an online survey. Participants responded to scales assessing minority stress (ie, internalized homophobia, experiences of harassment, microaggressions), perception of stress, generalized anxiety symptoms, and sleep disturbance. Linear regressions were used to test the relationship between minority stress and sleep disturbance and to test generalized anxiety symptoms and perception of stress as mediators. RESULTS The final model was significant (F = 16.916, p < .001) and accounted for 43.5% of the variance in sleep disturbance. Generalized anxiety symptoms and perception of stress fully mediated the relationships between minority stress and sleep disturbance. CONCLUSIONS Findings from this study suggest the need for psychological intervention to improve sleep for sexual minority men. Future research should test this model longitudinally, and include objective measures of stress. Future interventions could target stress perception using mindfulness or cognitive-based interventions.

Abstract
Increasing incidences of insomnia in adults, as well as the aging population, have been reported for their negative impact on the quality of life. Insomnia episodes may be associated with neurocognitive, musculoskeletal, cardiovascular, gastrointestinal, renal, hepatic, and metabolic disorders. Epidemiological evidence also revealed the association of insomnia with oncologic and asthmatic complications, which has been indicated as bidirectional. Two therapeutic approaches including cognitive behavioral therapy (CBT) and drugs-based therapies are being practiced for a long time. However, the adverse events associated with drugs limit their wide and long-term application. Further, Traditional Chinese medicine, acupressure, and pulsed magnetic field therapy may also provide therapeutic relief. Notably, the recently introduced cryotherapy has been demonstrated as a potential candidate for insomnia which could reduce pain, by suppressing oxidative stress and inflammation. It seems that the synergistic therapeutic approach of cryotherapy and the above-mentioned approaches might offer promising prospects to further improve efficacy and safety. Considering these facts, this perspective presents a comprehensive summary of recent advances in pathological aetiologies of insomnia including COVID-19, and its therapeutic management with a greater emphasis on cryotherapy.

[PMID: 35380374 PMCID: PMC8994715 DOI: 10.1007/s40263-022-00904-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 01/23/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Sodium oxybate has been recognized as a gold standard for the treatment of disrupted nighttime sleep due to narcolepsy. Its short half-life and immediate-release formulation require patients to awaken 2.5-4 h after their bedtime dose to take a second dose. A novel extended-release, once-nightly sodium oxybate formulation (ON-SXB; FT218) is under US Food and Drug Administration review for the treatment of adults with narcolepsy. OBJECTIVE A phase III trial of ON-SXB in individuals with narcolepsy type 1 (NT1) or 2 (NT2) [the REST-ON trial; NCT02720744] has been conducted and the primary results reported elsewhere. Secondary objectives from REST-ON were to assess the efficacy of ON-SXB on disrupted nighttime sleep; the results of this analysis are reported here. METHODS In the double-blind, phase III REST-ON trial, patients aged ≥ 16 years were randomly assigned 1:1 to ON-SXB (1 week, 4.5 g; 2 weeks, 6 g; 5 weeks, 7.5 g; 5 weeks, 9 g) or placebo. Secondary endpoints included polysomnographic measures of sleep stage shifts and nocturnal arousals and patient-reported assessments of sleep quality and refreshing nature of sleep at 6, 7.5, and 9 g; post hoc analyses included changes in time spent in each sleep stage, delta power, and assessments in stimulant-use subgroups for prespecified endpoints. RESULTS In total, 190 participants (n = 97, ON-SXB; n = 93, placebo) were included in the efficacy analyses. All three ON-SXB doses demonstrated a clinically meaningful, statistically significant decrease vs placebo in the number of transitions to wake/N1 from N1, N2, and rapid eye movement (REM) stages (all doses p < 0.001) and the number of nocturnal arousals (p < 0.05 ON-SXB 6 g; p < 0.001 7.5 and 9 g). Sleep quality and refreshing nature of sleep were significantly improved with all three ON-SXB doses vs placebo (p < 0.001). Post hoc analyses revealed a significant reduction in time spent in N1 (p < 0.05 ON-SXB 6 g; p < 0.001 7.5 and 9 g) and REM (all p < 0.001) and increased time spent in N3 with ON-SXB vs placebo (all p < 0.001), with a significant increase in delta power (p < 0.01 ON-SXB 6 g; p < 0.05 7.5 g; p < 0.001 9 g) and increased REM latency (ON-SXB 7.5 g vs placebo; p < 0.05). Significant improvements in disrupted nighttime sleep were observed regardless of concomitant stimulant use. CONCLUSIONS The clinically beneficial, single nighttime dose of ON-SXB significantly improved disrupted nighttime sleep in patients with narcolepsy.

Abstract
The paper addresses associations between sleep disorders and emotional and behavioral disturbances in children. These associations are considered in a view of commonly found co-occurrences of sleep problems, signs of anxiety and depression, oppositional-defiant behavior, and increased aggressiveness. The authors put forward a conception of reciprocal influences of these disturbances and provide information on potential physiological mechanisms responsible for associations between sleep problems and emotional and behavioral disturbances in children. Attention is drawn to hypothalamus-hypophysis-adrenal axis activation, serotonergic and aminergic systems imbalance, impaired melatonin and orexins production. Possibility of an existing pattern encompassing sleep problems, emotional and behavioral disturbances is discussed. Practical recommendations aimed at timely identification and treatment of the mentioned disorders are suggested.

Abstract
INTRODUCTION Attentional deficits and sleep problems are common in refugees who have experienced trauma. In the present study, we used polysomnography (PSG) to investigate the relationship between attentional deficits and objective measures of sleep structure in traumatized North Korean refugees. METHODS We recruited 32 North Korean refugees (mean age = 33.78 ± 14.33 years) and 39 South Korean participants (mean age = 35.03 ± 11.08 years). Sustained attention and divided attention were assessed using the Computerized Attention Test. We conducted an overnight PSG to objectively assess sleep structure. The participants also completed the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Impact of Event Scale-Revised (IES-R), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), and Insomnia Severity Index (ISI). RESULTS The North Korean refugees showed more commission errors (CEs, p < 0.05) and a larger standard deviation (SD) of the reaction time (RT) (p < 0.05) in the sustained attention task compared to the South Korean participants. Furthermore, the North Korean refugees showed a shorter period of wake after sleep onset (WASO, p < 0.01), less time spent in N1 (p < 0.05), and more time spent in N2 (p < 0.05). The larger SD of RT in the sustained attention task in the North Korean refugees was positively correlated with WASO (r = 0.62, p < 0.01) and N1 stage (r = 0.47, p < 0.05) after controlling for age, sex, BDI, BAI, and IES-R. CONCLUSION The North Korean refugees showed poorer performance on the sustained attention task. Nocturnal PSG revealed shorter WASO and time spent in N1 in this population, which are independently associated with the preservation of attentional capacity. These data suggest that traumatized refugees may compensate for attentional deficits induced by their traumatic experiences via increased sleep continuity.

Abstract
BACKGROUND Oral antiseizure medications (ASMs) are first-line treatments for patients with epilepsy. However, ASMs may alter sleep architecture, adversely affecting patient outcomes. The meta-analysis aimed to elucidate the effect of ASMs on sleep architecture. METHODS PubMed, Embase, and Cochrane Central database (up to Febrary 2021) were searched for randomized control trials (RCT) with effects of ASMs on polysomnography parameters. A meta-analysis using a random-effects model was performed. We did not set limitation to the participants with underlying diagnosis of epilepsy. RESULTS Eighteen randomized-controlled trials fulfilled the eligibility criteria. The effects of five main groups of ASMs (sodium channel blockers, calcium channel blockers, GABA enhancers, synaptic vesicle glycoprotein 2A [SV2A] ligand, and broad-spetrum ASMs) on slow-wave sleep (SWS), rapid eye movement (REM) sleep, and sleep efficiency (SE) were analyzed. Compared with placebo, calcium channel blockers and GABA enhancers significantly increased SWS. GABA enhancers also decreased REM sleep percentage, whereas calcium channel blockers significantly increased SE. Sodium channel blockers, SV2A ligand and broad-spectrum ASMs did not affect SWS, REM sleep, or SE. The subgroup analysis revealed that gabapentin, pregabalin, and tiagabine increased the percentage of SWS. Tiagabine also decreased REM sleep, whereas pregabalin increased SE. Finally, levetiracetam did not affect SWS, REM sleep, and SE. CONCLUSIONS This meta-analysis indicated that ASMs can have a statistically significant effect on sleep parameters; the effect differs between ASMs.

Insight into the relationship between sleep characteristics and anxiety: A cross-sectional study in indigenous and minority populations in northeastern Greece. Psychiatry Res 2020; 292:113361. [PMID: 32771838 DOI: 10.1016/j.psychres.2020.113361] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 08/01/2020] [Accepted: 08/02/2020] [Indexed: 10/23/2022]
Abstract
A cross-sectional population-based study was conducted in order to evaluate the association of sleep characteristics with anxiety disorders using self-reported questionnaires and taking into account several socio-demographic, lifestyle and health related characteristics. 957 participants between 19 and 86 years old were enrolled in our study. Anxiety symptoms were assessed using the Zung Self-rating Anxiety Scale. Participants self-reported their daily sleep habits and filled in the following scales: Epworth Sleepiness Scale, Athens Insomnia Scale, Pittsburgh Sleep Quality Index and Berlin Questionnaire. Overall prevalence of anxiety was 33.6%. Anxiety symptoms were more prominent among minority groups. Subjects with anxiety reported shorter sleep duration and reduced sleep efficiency. After adjusting for all possible confounders, they were five times more likely to exhibit short sleep duration (≤6h) and 0.60 times less likely long sleep duration (>8h). These relations remained significant in both genders, but were more pronounced among men. Moreover, anxiety was associated with excessive daytime sleepiness, insomnia, poor sleep quality and higher risk of obstructive sleep apnea (OSA). Results highlight the association of sleep disturbances with anxiety disorders and call for conduction of larger scale prospective studies in order to assess causality on the clinically important relationship between sleep characteristics and anxiety disorders.

Burns RD, Bai Y, Pfledderer CD, Brusseau TA, Byun W. Movement Behaviors and Perceived Loneliness and Sadness within Alaskan Adolescents. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E6866. [PMID: 32962220 PMCID: PMC7558989 DOI: 10.3390/ijerph17186866] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 09/16/2020] [Accepted: 09/18/2020] [Indexed: 01/02/2023]
Abstract
Physical activity, screen use, and sleep are behaviors that integrate across the whole day. However, the accumulative influence of meeting recommendations for these 24-h movement behaviors on the mental health of Alaskan adolescents has not been examined. The purpose of this study was to examine the associations between movement behaviors, loneliness, and sadness within Alaskan adolescents. Data were obtained from the 2019 Alaska Youth Risk Behavior Survey (YRBS). The number of adolescents participating in the 2019 Alaska YRBS was 1897. Associations between meeting recommendations for movement behaviors with loneliness and sadness were examined using weighted logistic regression models, adjusted for age, sex, race/ethnicity, and body mass index (BMI). Approximately 5.0% of the sample met recommendations for all three movement behaviors. Meeting 2 or 3 movement behavior recommendations was associated with lower odds of loneliness (odds ratio (OR) range = 0.23 to 0.44, p < 0.01). Additionally, meeting 1 to 3 movement behavior recommendations was associated with lower odds of sadness (OR range = 0.29 to 0.52, p < 0.05). Joint association analyses determined that these relationships were primarily driven by meeting the sleep recommendation for loneliness and meeting the screen use recommendation for sadness. The results support use of multiple movement-based behavior programming to attenuate feelings of loneliness and sadness within Alaskan adolescents.

Abstract
Sleep problems are common among children with neurodevelopmental disorders (NDDs). We review sleep disturbance in three major NDDs: autism spectrum disorder, Down syndrome, and fetal alcohol spectrum disorder (FASD). We review associations with functional impairment, discuss how patterns of sleep disturbance inform understanding of etiology, and theorize about mechanisms of impairment. Sleep disturbance is a transdiagnostic feature of NDDs. Caregivers report high rates of sleep problems, including difficulty falling or staying asleep. Polysomnography data reveal differences in sleep architecture and increased rates of sleep disorders. Sleep disturbance is associated with functional impairment and stress among families. Further research is needed to elucidate mechanisms of impairment and develop more effective interventions. Despite significant sleep disturbance in FASD, limited research is available.

Abstract
Anxiety disorders are prevalent and highly disabling mental disorders. In recent years, intensive efforts focused on the search for potential neuroimaging, genetic, and peripheral biomarkers in order to better understand the pathophysiology of these disorders, support their diagnosis, and characterize the treatment response. Of note, peripheral blood biomarkers, as surrogates for the central nervous system, represent a promising instrument to characterize psychiatric disorders, although their role has not been extensively applied to clinical practice. In this report, the state of the art on peripheral biomarkers of DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) Anxiety Disorders is presented, in order to examine their role in the pathogenesis of these conditions and their potential application for diagnosis and treatment. Available data on the cerebrospinal fluid and blood-based biomarkers related to neurotransmitters, neuropeptides, the hypothalamic-pituitary-adrenal axis, neurotrophic factors, and the inflammation and immune system are reviewed. Despite the wide scientific literature and the promising results in the field, only a few of the proposed peripheral biomarkers have been defined as a specific diagnostic instrument or have been identified as a guide in the treatment response to DSM-5 Anxiety Disorders. Therefore, further investigations are needed to provide new biological insights into the pathogenesis of anxiety disorders, to help in their diagnosis, and to tailor a treatment.

Abstract
BACKGROUND Childhood generalized anxiety disorder (GAD), characterized by uncontrollable worry, is associated with long-term psychopathology risk, yet understanding of developmental trajectories is limited. Despite common complaints about sleep, 'macro' sleep abnormalities have not been identified. Emerging findings suggest micro-architectural features of sleep, including sleep spindles, differentiate various psychiatric populations. The current study investigated sleep spindle density during non-rapid eye movement (NREM) sleep among youth with GAD and healthy controls, including relationships with anxiety, worry, global functioning, and subjective sleep quality. METHODS 58 pre-pubertal children, n = 26 with GAD and n = 32 matched healthy controls, aged 7-11 years (M = 8.86, SD=1.47), completed diagnostic assessments and a week of actigraphy monitoring prior to a night of polysomnography (PSG) either at home or in a sleep laboratory. NREM spindle activity was detected in frontal and central regions. RESULTS Sleep spindle activity did not differ based on diagnostic group or sex. Sleep spindles were unassociated with anxiety and sleep quality but showed a significant positive association with worry in all youth. Among youth with GAD, global functioning was negatively associated with spindle density in frontal regions during NREM stage 3. Spindle density was significantly greater during in-lab compared to at-home PSG. LIMITATIONS The small sample size and reliance on only one night of PSG necessitate additional studies. CONCLUSIONS The identified link between spindle activity and worry in pre-pubertal children highlights a need for investigations on transdiagnostic features of child psychopathology rather than specific disorders. Longitudinal studies are needed to explore spindle characteristics and affective risk across development.

Abstract
Anxiety and sleep function change dynamically across development, and sleep dysfunction has emerged as a correlate and predictor of anxiety in pediatric clinical samples. Despite this, previous research has not investigated how associations between qualitative and quantitative measures of sleep function change with anxiety across development, specifically from childhood to adolescence. The present study used actigraphy collection to examine whether associations between quantitative and qualitative sleep function and anxiety differed as a function of developmental stage in a community pediatric sample (8-17 years old; N = 92). Age moderated the association between anxiety and sleep quantity, but not sleep quality. Contrary to hypotheses, higher anxiety was related to increased sleep for children, but not adolescents. Results suggest age-related changes in the association between sleep function and anxiety across development, with implications for targeting sleep-related interventions for youth with anxiety.

Abstract
Anxiety disorders and behavioral sleep-related problems (SRPs) frequently co-occur during childhood. However, few studies have used the recommended method of a sleep-diary. The present study examined parental perceptions of behavioral SRPs in anxious compared to non-anxious children using a sleep-diary. Parents of 22 clinically anxious children and 29 healthy controls (aged 6-13 years) completed a 7-day sleep-diary of their child's behavioral SRPs. Compared to non-anxious peers, anxious children were rated by parents as more often (a) having a negative mood before bed, (b) delaying bed, (c) requiring parental assistance during the night, especially on weeknights, (d) having difficulty waking on their own the next morning, (e) falling back to sleep after morning waking, and (f) waking in a negative mood. There were no significant group differences in sleep onset latency or sleep duration, and behavioral SRPs of anxious children did not negatively affect their functioning or that of their parents the next day based on parent report. Parents of anxious children are more likely to perceive their children as engaging in behavioral SRPs compared to parents of non-anxious children.

Abstract
Children with anxiety disorders (AD) characteristically complain of sleep problems and the extent to which cognitive behavioral treatments (CBT) for childhood anxiety produce sleep-based improvements is a topic of increasing interest. The current paper reviews available evidence for subjective sleep complaints and objective sleep alterations in children and adolescents with AD, including investigations of potential changes in sleep following anxiety-focused CBT. Despite pervasive complaints of poor sleep, the empirical literature provides minimal evidence for actual sleep-wake alterations in this population of youth and evidence for sleep-based changes following treatment for anxiety is minimal. In line with calls for more comprehensive models of the role of sleep in developmental psychopathology, several fundamental gaps in understanding are described and highlighted as essential avenues for clarifying the nature and consequences of poor quality sleep among youth with clinical levels of anxiety. In a second section of the paper, an emerging body of novel, translational research investigating more intricate sleep-anxiety relationships is introduced with potential implications for both etiological models and treatment design and delivery.

Abstract
Zusammenfassung. Schlafprobleme und -störungen sind in Kindheit und Jugendalter weitverbreitet. Dieser Review beleuchtet den Zusammenhang zwischen Schlafproblemen und psychischen Störungen im Kindes- und Jugendalter. Schlafprobleme und -störungen gelten zum einen als Risikofaktoren für die Entwicklung psychischer Störungen, aber auch als Symptom und Auswirkung psychischer Störungen. Oft stehen Schlafverhalten und Psychopathologie in einer Wechselwirkung, sodass Schlafprobleme zur Intensität und Aufrechterhaltung psychischer Störungen beitragen. Dieser bidirektionale Zusammenhang ist sowohl in der frühen Kindheit als auch im Schulalter und bei Jugendlichen zu beobachten. Viele Studien konnten zeigen, dass es einen langfristigen Zusammenhang über die kindliche Entwicklung hinweg gibt. Sowohl Umweltfaktoren als auch genetische Faktoren scheinen bei der Entwicklung und Aufrechterhaltung dieses Zusammenhangs eine Rolle zu spielen. Diverse Forschungsergebnisse zeigen, dass die Behandlung von psychischen Störungen und die Behandlung von Schlafproblemen sich wechselseitig positiv beeinflussen. Daher ist die Berücksichtigung von Schlafproblemen in der Diagnostik und Behandlung, aber auch in der Prävention von psychischen Störungen dringend anzuraten.

Abstract
Sleep disturbance is prevalent in anxious youth and prospectively predicts poor emotional adjustment in adolescence. Study 1 examined whether anxiety treatment improves subjective and objective sleep disturbance in anxious youth. Study 2 examined whether a sleep intervention called Sleeping TIGERS can further improve sleep following anxiety treatment. Study 1 examined 133 youth (ages 9-14; 56% female; 11% ethnic/racial minority) with generalized, social, or separation anxiety over the course of anxiety treatment (cognitive behavioral treatment or client-centered treatment). Sleep-related problems (parent-, child-report) and subjective (diary) and objective (actigraphy) sleep patterns were assessed across treatment in an open trial design. Study 2 included 50 youth (ages 9-14; 68% female; 10% ethnic/racial minority) who continued to report sleep-related problems after anxiety treatment and enrolled in an open trial of Sleeping TIGERS. Pre- and postassessments duplicated Study 1 and included the Focal Interview of Sleep to assess sleep disturbance. Study 1 demonstrated small reductions in sleep problems and improvements in subjective sleep patterns (diary) across anxiety treatment, but outcomes were not deemed clinically significant, and 75% of youth stayed above clinical cutoff. Study 2 showed clinically significant, large reductions in sleep problems and small changes in some subjective sleep patterns (diary). Anxiety treatment improves, but does not resolve, sleep disturbance in peri-pubertal youth, which may portend risk for poor emotional adjustment and mental health. The open trial provides preliminary support that Sleeping TIGERS can improve sleep in anxious youth to a clinically significant degree.

Abstract
Sleep disturbances are often observed in child and adolescent mental health disorders. Although previous research has identified consistent subjective reports of sleep disturbances, specific objective sleep markers have not yet been identified. We evaluated the current research on subjective and objective sleep markers in relation to attention deficit hyperactivity disorders, autism spectrum disorders, anxiety and depressive disorders. Subjective sleep markers are more consistent than objective markers of actigraphy, polysomnography, and circadian measures. We discuss the causes of variability in objective sleep findings and suggest future directions for research.

Abstract
BACKGROUND Anxiety and depression are commonly comorbid with each other, with anxiety often temporally preceding the development of depression. Although increasingly research has begun to investigate the role of sleep problems in depression, no study has examined insomnia as a mediator in the longitudinal relationship between anxiety and subsequent depression. METHODS The current study utilizes data from Waves I, II, and IV of the National Longitudinal Study of Adolescent to Adult Health, a nationally representative prospective study conducted over a 14-year period (n = 20,745, 50.5% female, M age at Wave I = 16.20). Participants completed portions of the Center for Epidemiologic Studies Depression Scale at Waves I and IV to assess depressive symptoms, a six-item anxiety measure at Wave I, and three items assessing insomnia, sleep quality, and sleep duration at Wave II. RESULTS Structural equation modeling indicated that insomnia and unrestful sleep significantly mediated the relationship between anxiety and subsequent depression. The relationship between anxiety and depression was not significantly mediated by sleep duration. CONCLUSIONS Findings suggest that anxiety may increase risk for the development of later depression through insomnia.

Abstract
Insomnia is a clinical problem of significant public health importance. Insomnia can be a symptom or harbinger of other psychiatric disorders. Insomnia can also be comorbid with other psychiatric disorders, thereby adding to the medical burden and increasing the risk of psychiatric relapse. Insomnia can also be associated with medical and neurological disorders. Some medications can also cause insomnia. Treatment of insomnia can lead to positive outcomes, not only by alleviating symptoms and moderating these comorbid disorders, but by preventing new episodes. Therefore, it is vital to be aware of the relationship between insomnia and psychiatric illness. This article reviews this relationship and provides recommendations for management.

Abstract
Generalized anxiety disorder (GAD) is a prevalent and highly disabling mental health condition; however, there is still much to learn with regard to pertinent biomarkers, as well as diagnosis, made more difficult by the marked and common overlap of GAD with affective and anxiety disorders. Recently, intensive research efforts have focused on GAD, applying neuroimaging, genetic, and blood-based approaches toward discovery of pathogenetic and treatment-related biomarkers. In this paper, we review the large amount of available data, and we focus in particular on evidence from neuroimaging, genetic, and neurochemical measurements in GAD in order to better understand potential biomarkers involved in its etiology and treatment. Overall, the majority of these studies have produced results that are solitary findings, sometimes inconsistent and not clearly replicable. For these reasons, they have not yet been translated into clinical practice. Therefore, further research efforts are needed to distinguish GAD from other mental disorders and to provide new biological insights into its pathogenesis and treatment.

Abstract
STUDY OBJECTIVES Sleep bruxism (SB) is common in children and is associated with somatic symptoms and sleep disturbance. Etiological theories posit the role of anxiety, suggesting youth with anxiety disorders may be at high risk for SB, but empirical data are lacking. Furthermore, parent report rather than polysomnography (PSG) has been used to examine SB-anxiety relationships in children. We examined rates of PSG-detected compared to parent-reported SB in children with generalized anxiety disorder (GAD) and healthy controls. Associations among SB, somatic complaints, and sleep disturbance were also examined. METHODS Thirty-one children, aged 7-11 years, completed 1 night of PSG monitoring and 7 daily reports of somatic symptoms. Bruxism events were scored during stage R sleep, stage N1 sleep, and stage N2 sleep. RESULTS Almost one-third of children showed evidence of SB based on PSG. No associations were identified between parent-reported and PSG-detected SB. Rates of SB did not differ between anxious and control groups, though children with GAD showed more tonic bruxisms during stage R sleep. Presence of SB predicted more muscle aches and stomach aches, and children with SB had more awake time after sleep onset than those without bruxism. CONCLUSIONS Results indicate poor concordance between PSG-detected and parent-reported SB in children, suggesting that parent report alone is not a reliable method for detection. The lack of association between SB and anxiety status suggests that stress sensitivity rather than anxiety per se may be predictive of SB. Associations between SB, somatic symptoms, and sleep disturbance are congruent with the broader literature.

Abstract
Anxious youth typically experience sleep-related difficulties, but little is known about the role children's coping and perceived control over anxiety may play in these relations. We examined children's perceived levels of control over external anxiety-provoking events and internal anxious emotional reactions, as well as two dispositional coping tendencies (avoidant, support-seeking), and whether these were associated with anxious children's (N = 86) presleep arousal. Low perceived control over anxiety was significantly associated with high levels of presleep arousal. For children with low perceived control, higher avoidance was associated with greater presleep arousal, whereas lower avoidance was associated with lower presleep arousal levels. Findings suggest that efforts to avoid stressful life events may contribute to presleep arousal, especially under conditions where anxious arousal seems uncontrollable.

Abstract
OBJECTIVE Biomarkers are defined as anatomical, biochemical or physiological traits that are specific to certain disorders or syndromes. The objective of this paper is to summarise the current knowledge of biomarkers for anxiety disorders, obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD). METHODS Findings in biomarker research were reviewed by a task force of international experts in the field, consisting of members of the World Federation of Societies for Biological Psychiatry Task Force on Biological Markers and of the European College of Neuropsychopharmacology Anxiety Disorders Research Network. RESULTS The present article (Part II) summarises findings on potential biomarkers in neurochemistry (neurotransmitters such as serotonin, norepinephrine, dopamine or GABA, neuropeptides such as cholecystokinin, neurokinins, atrial natriuretic peptide, or oxytocin, the HPA axis, neurotrophic factors such as NGF and BDNF, immunology and CO2 hypersensitivity), neurophysiology (EEG, heart rate variability) and neurocognition. The accompanying paper (Part I) focuses on neuroimaging and genetics. CONCLUSIONS Although at present, none of the putative biomarkers is sufficient and specific as a diagnostic tool, an abundance of high quality research has accumulated that should improve our understanding of the neurobiological causes of anxiety disorders, OCD and PTSD.

Abstract
Anxiety affects millions of people and has been shown to co-occur in combination with sleep disturbances, generating heavy medical costs and a huge socio-medico-economic burden. Sleep-studies in anxiety disorders are inconsistent and the effects of state and trait anxiety are unexplored. We selected 1083 patients from the database of a hospital sleep laboratory. The patients had polysomnography for different sleep disorders; their sleep initiation (sleep onset latency), sleep maintenance (total sleep time), non-rapid eye movement sleep-, and rapid eye movement sleep parameters; as well as their State-Trait Anxiety Inventory and Beck depression scale were measured. In order to be included in our study, individuals needed to score in the low or high range on the State and/or Trait Subscales of the State-Trait Anxiety Inventory. We found that both state and trait anxiety affected non-rapid eye movement sleep parameters. Sleep onset latency changes predominantly associated to state anxiety while rapid eye movement parameters related to trait anxiety.

Abstract
Previous studies suggest that youth with anxiety disorders experience their sleep as more disrupted and unsatisfying than their healthy peers. However, it is unclear whether these subjective complaints align with objective measures of sleep quantity and quality. The purpose of this preliminary study was to assess subjective and objective sleep parameters, and their relationships with anxiety symptomatology, among adolescents (62.8% female, 81.4% Caucasian), ages 12 to 18 (M = 15.29 years), with generalized anxiety disorder (n = 26) and controls without any psychopathology (n = 17). We measured sleep over 7 nights using sleep diaries and actigraphy and collected self- and parent-report questionnaires pertaining to sleep, anxiety, and depression. Repeated-measures mixed models were used to examine relationships between nightly sleep duration and morning anxiety. We found a number of differences in sleep between our anxious and healthy participants. Via sleep diary, our anxious participants had longer sleep onset latencies and lower satisfaction with sleep relative to controls, whereas via actigraphy we found longer sleep onset latencies but greater overall sleep duration among anxious versus control participants. Actigraphic measures of sleep disturbance were associated with parent-report of anxiety and depression. Our mixed-model analyses revealed that decreases in nightly sleep duration were associated with increased morning anxiety, but only among our participants with generalized anxiety disorder. Findings suggest that sleep disturbance among anxious adolescents can be detected using both subjective and objective measures and that, for these individuals, fluctuations in sleep duration may have real consequences for daytime anxiety.

Abstract
It is increasingly clear that seminal sleep-affective relationships begin to take root in childhood, yet studies exploring how nighttime sleep characteristics relate to daytime affective symptoms, both in clinical and healthy populations of children, are lacking. The current study sought to explore these relationships by investigating whether trait-like and/or daily reports of affective and somatic symptoms of children with generalized anxiety disorder and matched controls relate to sleep architecture. Sixty-six children (ages 7-11; 54.4% female; 56.1% Caucasian; 18.2% biracial; 6.1% African American; 3% Asian; 16.7% Hispanic) participated including 29 with primary generalized anxiety disorder (without comorbid depression) and 37 healthy controls matched on age and race/ethnicity. Participants underwent structured diagnostic assessments including child-report measures and subsequently reported on their negative affect and somatic symptoms over the course of 1 week. Children also completed 1 night of polysomnography. Among children with generalized anxiety disorder only, greater amounts of slow wave sleep corresponded with less negative affect, and greater amounts of rapid eye movement sleep was related to more somatic complaints across the week. Similarly, for trait-like measures, more rapid eye movement sleep and shorter latency to rapid eye movement sleep were related to greater depressive symptoms in the anxious group only. The current findings suggest that physiologic sleep characteristics may contribute in direct ways to the symptom profiles of clinically anxious children. The functional relevance of such findings (e.g., how specific sleep characteristics serve to either increase or reduce long-term risk) is a vital direction for future research.

Abstract
Investigating sleep in mental disorders has the potential to reveal both disorder-specific and transdiagnostic psychophysiological mechanisms. This meta-analysis aimed at determining the polysomnographic (PSG) characteristics of several mental disorders. Relevant studies were searched through standard strategies. Controlled PSG studies evaluating sleep in affective, anxiety, eating, pervasive developmental, borderline and antisocial personality disorders, attention-deficit-hyperactivity disorder (ADHD), and schizophrenia were included. PSG variables of sleep continuity, depth, and architecture, as well as rapid-eye movement (REM) sleep were considered. Calculations were performed with the "Comprehensive Meta-Analysis" and "R" software. Using random effects modeling, for each disorder and each variable, a separate meta-analysis was conducted if at least 3 studies were available for calculation of effect sizes as standardized means (Hedges' g). Sources of variability, that is, sex, age, and mental disorders comorbidity, were evaluated in subgroup analyses. Sleep alterations were evidenced in all disorders, with the exception of ADHD and seasonal affective disorders. Sleep continuity problems were observed in most mental disorders. Sleep depth and REM pressure alterations were associated with affective, anxiety, autism and schizophrenia disorders. Comorbidity was associated with enhanced REM sleep pressure and more inhibition of sleep depth. No sleep parameter was exclusively altered in 1 condition; however, no 2 conditions shared the same PSG profile. Sleep continuity disturbances imply a transdiagnostic imbalance in the arousal system likely representing a basic dimension of mental health. Sleep depth and REM variables might play a key role in psychiatric comorbidity processes. Constellations of sleep alterations may define distinct disorders better than alterations in 1 single variable. (PsycINFO Database Record

Attention-deficit hyperactivity disorder symptoms add risk to circadian rhythm sleep problems in depression and anxiety. J Affect Disord 2016; 200:74-81.

Abstract
BACKGROUND Comorbid ADHD symptoms may partly account for circadian rhythm disturbances in depression and anxiety disorders. METHODS Self-reported sleep characteristics of 2090 participants in the Netherlands Study of Depression and Anxiety were assessed using the Munich Chronotype Questionnaire. We defined 3 groups: healthy controls (HC), persons with lifetime depression and/or anxiety disorders (LDA), and those with both LDA and high ADHD symptoms (LDA+ADHD), using the Conner's Adult ADHD Rating Scale. RESULTS Sleep characteristics were least favorable in the LDA+ADHD group. Important group differences between LDA+ADHD, LDA and HC were found for extremely late chronotype (12% vs. 5% vs. 3%; p<.001), sleep duration <6h (15% vs. 5% vs. 4%; p<.001), and for an indication of the Delayed Sleep Phase Syndrome (DSPS; 16% vs. 8% vs. 5%; p<.001). After adjustment for covariates, including depression and anxiety, presence of ADHD symptoms increased the odds ratio for late chronotype (OR=2.6; p=.003), indication of DSPS (OR=2.4; p=.002), and sleep duration <6h (OR=2.7; p=.007). LIMITATIONS ADHD conceptually overlaps with symptom presentation of depression and anxiety. We used a cross-sectional study design, and used self reported sleep characteristics. CONCLUSIONS High ADHD symptoms were associated with an increased rate of circadian rhythm sleep disturbances in an already at-risk population of people with depression and/or anxiety disorders. Circadian rhythm sleep disorders, as often seen in ADHD are not entirely due to any comorbid depression and/or anxiety disorder. Adequate treatment of such sleep problems is needed and may prevent serious health conditions in the long term.

Abstract
We compared subjective and objective sleep patterns and problems, and examined cross-method correspondence across parent reports, child reports, and actigraphy-derived sleep variables in clinically-anxious children and healthy controls. In a multi-site, cross-sectional study, 75 pre-adolescent children (6 to 11 years; M = 8.7 years; SD = 1.4; n = 39/52 % female) were examined including 39 with a diagnosis of primary generalized anxiety disorder (GAD) and 36 controls recruited from university-based clinics in Houston, TX and Washington, DC. Structured interviews, validated sleep questionnaires, and 1 week of actigraphy data were utilized. Despite subjective reports of significantly greater sleep problems among anxious children, actigraphy data revealed no significant differences between the groups. All parents estimated earlier bedtimes and greater total sleep duration relative to actigraphy, and all children endorsed more sleep problems than parents. With few exceptions, subjective reports exhibited low and non-significant correspondence with actigraphy-based sleep patterns and problems. Our findings suggest that high rates of sleep complaints found among children with GAD (and their parents) are not corroborated by objective sleep abnormalities, with the exception of marginally prolonged sleep onset latency compared to controls. Objective-subjective sleep discrepancies were observed in both groups but more apparent overall in the GAD group. Frequent complaints of sleep problems and daytime tiredness among anxious youth might more accurately reflect difficulties prior to the actual sleep period, cognitive-affective biases associated with sleep, and/or poor sleep quality. Findings highlight the importance of considering sleep from multiple perspectives.

Abstract
BACKGROUND Hippocrates flagged the value of sleep for good health. Nonetheless, historically, researchers with an interest in developmental psychopathology have largely ignored a possible role for atypical sleep. Recently, however, there has been a surge of interest in this area, perhaps reflecting increased evidence that disturbed or insufficient sleep can result in poor functioning in numerous domains. This review outlines what is known about sleep in the psychiatric diagnoses most relevant to children and for which associations with sleep are beginning to be understood. While based on a comprehensive survey of the literature, the focus of the current review is on the latest science (largely from 2010). There is a description of both concurrent and longitudinal links as well as possible mechanisms underlying associations. Preliminary treatment research is also considered which suggests that treating sleep difficulties may result in improvements in behavioural areas beyond sleep quality. FINDINGS To maximise progress in this field, there now needs to be: (a) greater attention to the assessment of sleep in children; (b) sleep research on a wider range of psychiatric disorders; (c) a greater focus on and examination of mechanisms underlying associations; (d) a clearer consideration of developmental questions and (e) large-scale well-designed treatment studies. CONCLUSIONS While sleep problems may sometimes be missed by parents and healthcare providers; hence constituting a hidden risk for other psychopathologies - knowing about these difficulties creates unique opportunities. The current excitement in this field from experts in diverse areas including developmental psychology, clinical psychology, genetics and neuropsychology should make these opportunities a reality.

Abstract
Recent research suggests that sleep disturbance may be a transdiagnostic process, and there is increasing interest in examining how sleep disturbance may contribute to anxiety and related disorders. The current review summarizes and synthesizes the extant research assessing sleep in anxiety and related disorders. The findings suggest that sleep disturbance exacerbates symptom severity in the majority of anxiety and related disorders. However, the nature of sleep disturbance often varies as a function of objective versus subjective assessment. Although sleep disturbance is a correlate of most anxiety and related disorders, a causal role for sleep disturbance is less clear. A model of potential mechanisms by which sleep disturbance may confer risk for the development of anxiety and related disorders is discussed. Future research integrating findings from basic sleep research with current knowledge of anxiety and related disorders may facilitate the development of novel treatments for comorbid sleep disturbance and clinical anxiety.

Abstract
PURPOSE OF REVIEW Adolescence is a period of dynamic change in both sleep and emotional systems, with related increases in problems controlling emotion and behavior. Youth with anxiety enter adolescence with pre-existing vulnerabilities in systems of sleep and emotion that may place them at heightened risk. This review summarizes recent research on sleep and anxiety during the transition to adolescence, and highlights emerging themes. RECENT FINDINGS Prospective studies support that sleep predicts anxiety symptoms in early adolescence. Notably, robust evidence for subjective sleep problems in anxious youth is not well corroborated by objective assessments. Longitudinal designs and methodology that carefully examine dimensions of anxiety and sleep may clarify inconsistencies. Preliminary evidence suggests that late childhood to early adolescence may be a sensitive period for escalating problems with sleep and anxiety. Recent advances in the neuroscience of sleep can further refine integrative mechanistic models of developmental psychopathology - the role of sleep in emotional learning and memory is provided as an example. SUMMARY Sleep problems are common and prospectively predict escalating anxiety symptoms. Precision is needed regarding the nature of sleep disruption, and how and when sleep affects various aspects of developmental trajectories. This precision, along with advances in the neuroscience of sleep, may lead to developmentally informed translational interventions.

Abstract
This review examines the relationship between anxiety disorders and sleep related problems (SRPs) in school-aged youth. Following an overview of normative sleep patterns and maturational sleep changes, the review addresses issues related to sleep measurement. SRPs are reviewed in relation to executive functions (e.g. affect regulation) as is the shared role of neurological regions in the regulation of anxiety and sleep. Studies of the association between SRPs and anxiety in anxiety-disordered samples are reviewed with explicit consideration of the potential mechanisms underlying the sleep-anxiety relationship (e.g., arousal, sleep hygiene, parental accommodation). Specific cognitive-behavioral treatments for SRPs and anxiety are reviewed with regard to their impact on comorbid anxiety or SRPs. Methodological limitations are noted and recommendations for future research are proposed.

Abstract
Sleep disturbances are common in pediatric psychiatric disorders and constitute key elements in diagnostic symptomatology of various primary psychiatric disorders including bipolar disorder, depression, and anxiety disorder. Although sleep is not included in key defining criteria of some impairing illnesses such as obsessive-compulsive disorder and schizophrenia, these disorders present with a very high prevalence of sleep disturbances. The interaction between sleep and psychopathology is very complex with significant interrelationship in development, severity, and prognosis of psychiatric disorders and comorbid sleep disturbances. The research ranging from small intervention case series to large epidemiologic studies have demonstrated the role of specific sleep complaints in specific psychiatric diagnoses. However, the research using objective instruments such as polysomnography and actigraphy remains limited in youth with psychiatric disorders. The intervention studies using pharmaceutical treatment specifically focusing on sleep disturbances in psychiatric disorders are also sparse in the pediatric literature. Early identification of sleep disturbances and behavioral management using cognitive behavior therapy-based tools appear to be the most effective approach for treatment. The use of psychotropic medications such as selective serotonin reuptake inhibitors for the treatment of primary psychiatric disorder often alleviate the psychological barriers for sleep but may lead to emergence of other sleep issues such as restless leg syndrome. The safety and efficacy data of hypnotics for primary sleep disorders are limited in pediatrics and should be avoided or used with extreme caution in children with comorbid sleep and psychiatric problems.

Abstract
Sleep problems are common in children and adolescents. A growing body of research has explored the relationship between sleep problems and anxiety in youth. When reviewing the literature, methodologic inconsistencies need to be considered, such as variation in conceptualization of sleep problems, measurement of sleep, and the classification of anxiety. Despite this, there seems to be good evidence of concurrent and longitudinal associations between sleep difficulties and anxiety in community and clinical samples of young people. Potential mechanisms are proposed. There is a need for further exploration of these relationships, with the hope of aiding preventive capability and developing useful treatments.

Abstract
OBJECTIVES To investigate the presence of sleep problems and their reaction to CBT in pediatric obsessive compulsive disorder (OCD). Moreover, we investigated whether sleep problems predict the outcome of CBT on OCD-symptoms. METHODS 269 children and adolescents, age 7-17 years, with DSM-IV primary OCD that took part in the first step of a stepwise treatment trial, were assessed with regard to both individual sleep problems and a sleep composite score (SCS) using the Child Behavior Checklist (CBCL). Their OCD symptoms were rated using the Children Yale-Brown Obsessive Compulsive Scale (CY-BOCS). RESULTS We found elevated symptoms of sleep deprivation and nightmares before treatment. However most sleep problems (e.g. nightmares (p=.03), too little sleep (p<.001), trouble sleeping (p<.001) and parasomnias p=.03)) as well as being over-tired (p<.001) reduced during CBT treatment. Co-morbidities had no effect on the reduction of SCS. Moreover, elevated levels of sleep problems using the SCS (p<.001), as well as any sleep problem at baseline (p<.001) predicted less effect of CBT on the OCD symptoms. CONCLUSION Sleep problems in paediatric OCD are frequent and interfere with treatment outcome. They need to be assessed using better methods in future trials. Moreover, lack of resolution of sleep problems need to be recognized and treated as it seems probable that continued sleep problems may have a negative impact on CBT efficacy.

Polysomnographic sleep characteristics of generally-anxious and healthy children assessed in the home environment. J Affect Disord 2014; 161:79-83. [PMID: 24751311 PMCID: PMC4405028 DOI: 10.1016/j.jad.2014.02.037] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2014] [Accepted: 02/28/2014] [Indexed: 11/21/2022]
Abstract
BACKGROUND Using laboratory-based polysomnography (PSG) we recently provided evidence of significantly prolonged sleep onset latency (SOL) and reduced latency to rapid eye movement (REM) sleep among non-depressed children with generalized anxiety disorder (GAD) compared to healthy age-matched controls. In the current study we conducted unattended ambulatory PSG in a new sample of children with GAD and controls in order to examine sleeping characteristics in the home environment. METHOD Thirty-two children (ages of 7-11 years) including 16 children with primary GAD and 16 controls receiving no psychotropic medications were studied. The anxious group had a primary diagnosis of GAD without secondary mood disorders and controls were free of any medical or psychiatric diagnoses. All participants underwent structured diagnostic assessments and completed one night of home-based polysomnography (PSG). RESULTS Children with GAD exhibited significantly higher sleep efficiency (SE) and fewer rapid eye movement (REM) sleep periods compared to controls. Self-reported somatic arousal during the pre-sleep period was negatively correlated with the percentage of total REM sleep among controls, but positively correlated with REM sleep percentage in the GAD group. LIMITATIONS A small sample size and one night of PSG only. CONCLUSIONS Home-based PSG recording do not provide evidence of disrupted sleep patterns in children with GAD. Contextual factors that better elucidate differences between laboratory and home-based sleep findings are suggested as important directions for future research.

Abstract
OBJECTIVE We tested whether sleep problems co-occur with, precede, and/or follow common psychiatric disorders during childhood and adolescence. We also clarified the role of comorbidity and tested for specificity of associations among sleep problems and psychiatric disorders. METHOD Data came from the Great Smoky Mountains Study, a representative population sample of 1,420 children, assessed 4 to 7 times per person between ages 9 and 16 years for major Diagnostic and Statistical Manual-Fourth Edition (DSM-IV) disorders and sleep problems. Sleep-related symptoms were removed from diagnostic criteria when applicable. RESULTS Sleep problems during childhood and adolescence were common, with restless sleep and difficulty falling asleep being the most common symptoms. Cross-sectional analyses showed that sleep problems co-occurred with many psychiatric disorders. Longitudinal analyses revealed that sleep problems predicted increases in the prevalence of later generalized anxiety disorder (GAD) and high GAD/depression symptoms, and oppositional defiant disorder (ODD). In turn, GAD and/or depression and ODD predicted increases in sleep problems over time. CONCLUSIONS Sleep problems both predict and are predicted by a diagnostic cluster that includes ODD, GAD, and depression. Screening children for sleep problems could offer promising opportunities for reducing the burden of mental illness during the early life course.

Abstract
BACKGROUND Research on the neurobiological basis of Generalized Anxiety Disorder (GAD) has considerably expanded in recent years. However, many studies investigated different domains and used different methods and paradigms. Therefore, this review aims to integrate the findings to date and to identify the core correlates of neurobiological underpinnings of GAD discovered so far. METHODS We conducted a systematic review of original papers investigating neural correlates, connectivity, or structural changes as well as reporting changes in the serotonergic system, noradrenergic system and cortisol levels in DSM-IV-defined GAD samples until December 2013. RESULTS Studies have identified abnormal amygdala and prefrontal cortex activation in patients and decreased functional connectivity between these areas. Furthermore, studies showed increased gray matter volume and decreased structural connectivity between these structures. Neuroendocrine findings are less consistent, but increased reactivity of the noradrenergic system and perpetuations in the cortisol secretion have been reported. LIMITATIONS Only studies on DSM-IV defined Generalized Anxiety Disorder which employed a group comparison were included. CONCLUSIONS Current research suggests a distinct set of neurobiological alterations in Generalized Anxiety Disorder. However, future research on the interaction between these structures and systems and on the specificity of these findings in relation to other mental disorders is urgently needed.

Abstract
Although social anxiety disorder (SAD) is most often diagnosed during adolescence, few investigations have examined the clinical presentation and daily functional impairment of this disorder exclusively in adolescents. Prior studies have demonstrated that some clinical features of SAD in adolescents are unique relative to younger children with the condition. Furthermore, quality of sleep, a robust predictor of anxiety problems and daily stress, has not been examined in socially anxious adolescents. In this investigation, social behavior and sleep were closely examined in adolescents with SAD (n = 16) and normal control adolescents (NC; n = 14). Participants completed a self-report measure and an actigraphy assessment of sleep. Social functioning was assessed via a brief speech and a social interaction task, during which heart rate and skin conductance were measured. Additionally, participants completed a daily social activity journal for 1 week. No differences were observed in objective or subjective quality of sleep. Adolescents with SAD reported greater distress during the analogue social tasks relative to NC adolescents. During the speech task, adolescents with SAD exhibited a trend toward greater speech latency and spoke significantly less than NC adolescents. Additionally, SAD participants manifested greater skin conductance during the speech task. During the social interaction, adolescents with SAD required significantly more confederate prompts to stimulate interaction. Finally, adolescents with SAD reported more frequent anxiety-provoking situations in their daily lives, including answering questions in class, assertive communication, and interacting with a group. The findings suggest that, although adolescents with SAD may not exhibit daily impaired sleep, the group does experience specific behavioral and physiological difficulties in social contexts regularly. Social skills training may be a critical component in therapeutic approaches for this group.
