Exploring sleep quality of young children with autism spectrum disorder and disruptive behaviors

Sleep Problems, Circadian Rhythms, and Their Relation to Behavioral Difficulties in Children and Adolescents with Autism Spectrum Disorder

This was an exploratory cross-sectional study comparing 45 children with ASD to 24 typically developing drug-naïve controls, group-matched on age, sex, and body mass index. Objective data was obtained using the following: an ambulatory circadian monitoring device; saliva samples to determine dim light melatonin onset (DLMO): and three parent-completed measures: the Child Behavior Checklist (CBCL); the Repetitive Behavior Scale-Revised (RBS-R); and the General Health Questionnaire (GHQ28). The CBCL and RBS-R scales showed the highest scores amongst poor sleepers with ASD. Sleep fragmentation was associated with somatic complaints and self-injury, leading to a higher impact on family life. Sleep onset difficulties were associated with withdrawal, anxiety, and depression. Those with phase advanced DLMO had lower scores for "somatic complaints"; "anxious/depressed" state; and "social problems", suggesting that this phenomenon has a protective role.

The Type, Severity, and Impact of Sleep Problems in Children With Angelman Syndrome and Parental Help-seeking Patterns

Angelman syndrome (AS) is a rare genetic developmental disability that presents with high rates of co-occurring sleep difficulties. Most existing research has focused on the pathophysiology of sleep problems in people with AS, and suggests that sleep problems are the result of genetic and neurobiological factors. However, little is known about the role of the social environment and learning in sleep problems in children with AS. This descriptive study used survey data from 139 parents of children with AS to investigate: 1) the type, topography and severity of children's sleep problems; 2) the collateral child, parent and family impacts of the sleep problems; 3) treatment selection practices and the perceived effectiveness of these treatments; and 4) sources of support and treatment advice received. Parents reported that the majority of children experienced sleep problems, resulting in numerous deleterious effects on child and family functioning. They also reported high levels of concern about these sleep problems, but low levels of perceived support. Study findings highlight the need to establish a disability-specific profile of the type and impact of sleep problems experienced by children with AS, and have further implications for the delivery of clinical services and support provided to parents of children with AS.

Qualitative Exploration Toward the Development of a Parent-Rated Scale for Insomnia in Children with Autism Spectrum Disorder

Toward the development of a new parent-rating for insomnia, this multi-site qualitative study explored sleep problems and related impacts in children with autism spectrum disorder (ASD) and their families. To ensure content validity of the measure, we conducted six focus groups with caregivers (N = 25) of 24 children (age 3 to 18 years) with ASD. Based on parent report, all children had a history of mild or greater insomnia. The focus group transcripts were systematically coded to identify major themes. Verbatim comments from caretakers were used to generate 134 candidate items. Further review by the research team and an expert panel followed by individual cognitive interviews with 12 parents reduced the item bank to 40. The thematic analysis of focus group transcripts identified 7 categories: (1) Trouble falling asleep; (2) trouble staying asleep; (3) early morning waking; (4) bedtime routines; (5) parental strategies for bedtime management; (6) impact of sleep problems on the child; and (7) impact of sleep problems on the family. The Flesch Kincaid Grade Level of the 40-item version was 7.2 (seventh grade reading level). Insomnia in children with ASD shares features in common with insomnia in the general pediatric population. However, perhaps owing to autistic features such as insistence on sameness, sensory sensitivities, communication impairments, insomnia in children with ASD appears to have unique behavioral manifestations. Content validity and item clarity of the 40-item bank were supported by expert panel review and cognitive interviews with caregivers of children with ASD.

Correlates of Impairment and Growth in Families of Young Autistic Children

The purpose of this project was to investigate potential correlates of family life impairment in families of young autistic children. This project incorporated measures of specific child and parent challenges in addition to a commonly used unidimensional measure of autism characteristics. In this way, we could assess whether such challenges explain variance in family life impairment, and whether their inclusion diminish associations between autism characteristics and family life impairment. Cross-sectional data were collected from 564 parents of autistic children aged 2 to 5 years who participated in a larger online study. Participants completed measures on child characteristics (autism characteristics, emotion dysregulation, speaking ability, flexibility, and sleep problems), parent depression, and family life impairment, using the Family Life Impairment Scale (FLIS). Multiple linear regression models were generated to examine whether any of the independent variables were associated with the four domains of the FLIS. Models controlled for child age and sex, parent education, and single-parent homes. All independent variables were associated with impairment in one or more FLIS domains. None of the primary independent variables were significantly associated with positive growth. More overt characteristics and behaviors (e.g., autism characteristics, reactivity, speaking ability, and flexibility) were associated with impairment in domains that reflected a family's ability to navigate the community. However, sleep challenges and parent and child emotional difficulties were most strongly associated with parent impairment. Findings suggests that families may have different needs across contexts and provide new avenues through which they might be better supported.

Sleep and Autism: Current Research, Clinical Assessment, and Treatment Strategies

Autism spectrum disorder is associated with a high rate of sleep problems, affecting over 80% of autistic individuals. Sleep problems have pervasive negative effects on health, behavior, mood, and cognition but are underrecognized in autistic children. Problems initiating and maintaining sleep-hallmarks of insomnia-are common. Sleep-disordered breathing and restless legs syndrome have also been described in autism at a higher prevalence than in community populations. The authors describe current research on sleep in autistic children and potential pathophysiologic mechanisms. They describe practical approaches to sleep assessment and synthesize approaches to addressing sleep problems in autistic children.

Sleep Problems in Autism Spectrum Disorder

Sleep problems are common in children with autism spectrum disorder (ASD), with 40% to 80% prevalence. Common disorders include insomnia, parasomnias, and circadian rhythm sleep-wake disorders. These problems have a multifactorial etiology and can both exacerbate and be exacerbated by core ASD symptoms. Sleep problems also impact the health and quality of life of both patients and their caregivers. All children with autism should be regularly screened for sleep problems and evaluated for co-occurring medical contributors. Behavioral interventions with caregiver training remain first-line treatment for sleep disorders in both neurotypical and neurodiverse youth.

Autism Spectrum Disorder and Sleep

Children and adolescents with autism spectrum disorder (ASD) experience sleep disturbances, particularly insomnia, at rates much higher than the general population. Daytime behavioral problems and parental stress are associated with the resultant sleep deprivation. Behavioral interventions, parental education, and melatonin are effective treatments. The epidemiology of sleep disturbances in youth with ASD is reviewed in this article as well as the latest in treatments.

Incidence of Otolaryngological Manifestations in Individuals with Autism Spectrum Disorder: A Special Focus on Auditory Disorders

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by stereotyped and repetitive behavior patterns. In addition to neurological and behavioral problems, individuals with ASD commonly experience otolaryngological comorbidities. Individuals with ASD often have auditory disorders including hearing loss and auditory processing disorders such as central auditory processing disorder (CAPD), as well as both chronic and recurrent otitis media. These challenges negatively impact a person's ability to effectively communicate and may further impact their neurological functioning, particularly when not appropriately treated. Individuals diagnosed with ASD also have difficulty sleeping which contributes to increased irritability and may further aggravate the core behavioral symptoms of autism. The individuals with ASD also have a higher rate of sinusitis which contributes to the worsening of the autism behavior phenotype. The high prevalence of otolaryngological comorbidities in individuals with ASD warrants a better collaboration between their various healthcare providers and otolaryngologists with expertise in auditory, sleep, and sinus disorders in pursuit of improving the quality of life of affected individuals and their families/caregivers.

Insomnia in Children with Autism Spectrum Disorder: A Cross-Sectional Study on Clinical Correlates and Parental Stress

Insomnia is one of the most common co-occurring disorders in children with autism spectrum disorder (ASD). The purpose of this cross-sectional cohort study of 270 children with ASD was to assess the prevalence of insomnia using the Pediatric Sleep Clinical Global Impression Scale and to correlate sleep problems with cognitive level, adaptive behavior, parental stress, behavioral and emotional problems, and severity of core symptoms. Our findings revealed that one-third of children had insomnia and were related to reduced adaptive behaviors and higher levels of parental stress and behavioral and emotional problems. Insomnia must be evaluated in children with ASD to define an appropriate intervention to potentially alleviate the severity of clinical correlates and parental burden.

Management of sleep disorders in autism spectrum disorder with co-occurring attention-deficit hyperactivity disorder: update for clinicians

AIMS

To update and examine available literature germane to the recognition, assessment and treatment of comorbid autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD) and sleep disruption, with a predominant focus on children, adolescents and emerging adults.

BACKGROUND

Considerable overlaps exist among ASD, ADHD and sleep disruption. Literature and guidance for clinicians, administrators, policy makers and families have been limited, as such deliberations were rarely considered until 2013.

METHOD

This narrative review of the literature addressing sleep disruption issues among those with ASD, ADHD and comorbid ASD and ADHD involved searching multiple databases and use of reverse citations up to the end of September 2022. Emphasis is placed on secondary sources and relevant data for clinical practice.

RESULTS

Complex clinical presentations of ASD/ADHD/sleep disruption are frequently encountered in clinical practice. Prior to 2013, prevalence, clinical presentation, pathophysiology, prognosis, other sleep-related factors and interventions were determined separately for each disorder, often with overlapping objective and subjective methods employed in the process. High percentages of ADHD and ASD patients have both disorders and sleep disruption. Here, the extant literature is integrated to provide a multidimensional understanding of the relevant issues and insights, allowing enhanced awareness and better care of this complex clinical population. Database limitations are considered.

CONCLUSIONS

Assessment of ASD symptomatology in youth with ADHD, and the reverse, in cases with disrupted sleep is critical to address the special challenges for case formulation and treatment. Evidence-based approaches to treatment planning and multi-treatment modalities should consider combining psychosocial and biological interventions to address the complexities of each case.

Telehealth parent training for sleep disturbances in young children with autism spectrum disorder: A randomized controlled trial

BACKGROUND AND PURPOSE

Young children with autism spectrum disorder (autism) have bedtime and sleep disturbances at much higher frequency and persistency than their neurotypical counterparts. Hence, access to early, effective treatment is critical in view of the importance of sleep in early childhood. Telehealth delivery could be a means to expand access to such early treatment if efficacious. The aim of this randomized control trial (RCT) was to compare a manualized, telehealth delivered, behaviorally based sleep parent training (SPT) intervention for parents of young children with autism and sleep disturbances to a control condition, a telehealth delivered parent education program with one sleep focused session (SPE). We hypothesized that the SPT group would show more improvements on child measures of sleep outcome measures, and daytime behaviors and parent measures of stress and sense of competence. We further aimed to explore the overall feasibility of telehealth delivery of SPT and SPE.

PARTICIPANTS AND METHODS

Parents of 77 young children, ages 2-7 years, with autism and co-occurring sleep disturbances were enrolled in this study. Participants were randomized to either SPT or a comparison arm that included non-sleep related parent education except for one session. Each participant was individually administered a 5 session program delivered over 10 weeks. Outcome measures, including child sleep measures, child daytime behavior and parent stress and sense of competency were collected at weeks 5 and 10 after the baseline time point. Feasibility indicators (treatment fidelity, parent adherence, and parent attendance), and safety measures were also collected.

RESULTS

Of 77 randomized participants, data were available for 36 participants randomized to SPT and 38 participants randomized to SPE. The mean age was 3 years, 8 months. Results support the efficacy of this manualized SPT intervention for bedtime and sleep disturbances. Sleep outcome measures were significantly improved in the SPT group compared to SPE on the Modified Simonds & Parraga Sleep Questionnaire-Composite Sleep Index (MSPSQ - CSI) (p < 0.001) with a large effect size of 0.83 at week 10. Positive response to treatment, as determined from the Clinical Global Impression-Improvement scale (CGI-I) at week 10 was observed in 56% of SPT participants compared to 32% in SPE (p = 0.037). There were no significant group differences in either the ABC-I as measure of daytime behaviors or in parental stress. There were group differences in favor of SPT over SPE on the PSOC, a measure of parent sense of competency. Feasibility and safety were further demonstrated with telehealth delivery.

CONCLUSIONS

This RCT demonstrated the efficacy of a telehealth delivered parent training intervention for bedtime and sleep disturbances in young autistic children compared to an active control condition. Further, parents in SPT reported more confidence in their parenting role than those in the SPE group, but SPT did not result in overall decreases in parental stress. Telehealth delivery allowed for a much broader reach with enrolled participants from 24 states. This study supports a telehealth approach to a manualized behavioral parent mediated intervention for sleep disturbance in young autistic children and offers an alternative to in-person delivered approaches. This telehealth delivery has the potential to improve access for families who have a young autistic child with sleep disturbances. Given the small sample size, determining predictors and moderators of treatment response was not possible and should be examined in a larger trial.

Feasibility of Actigraphy for Evaluating Sleep and Daytime Physical Activity in Children with Autism Spectrum Disorder

This research evaluated the feasibility of actigraphy to measure sleep and physical activity in children (ages 2-8 years) with autism spectrum disorder (ASD). We also explored associations between sleep and physical activity. Validated screening measures established eligibility. Questionnaires, diaries, and 5 days and 5 nights of actigraphy monitoring were used to collect data. Of the 32 children enrolled, 27 (84.4%) completed actigraphy monitoring. Based on the median steps per day, children with high physical activity had lower total sleep time and more disruptive behaviors than children with low physical activity. Findings support the feasibility of using actigraphy to measure sleep and physical activity in children with ASD. Larger studies are needed to evaluate interactions of physical activity on sleep in this population.

Sleep disturbances are associated with irritability in ASD children with sensory sensitivities

BACKGROUND

Parent reports suggest that 44-84% of children with ASD exhibit sleep disturbances that are of clinical concern. Previous studies have reported that, in children with ASD, the severity of sleep disturbances is associated with the severity of either sensory problems or aberrant behaviors, but none have performed combined analyses with measures of both sensory and aberrant behaviors symptom domains from the same children.

METHODS

We examined parent reports of 237 children with ASD, 1.4-8.7 years old, using the child sleep habits questionnaire (CSHQ), sensory profile (SP), and aberrant behaviors checklist (ABC).

RESULTS

The analyses revealed that sleep disturbances were most strongly associated with SP sensory sensitivity and ABC irritability scores. Together these scores explained 35% of the variance in total CSHQ scores. Moreover, sensory sensitivity scores moderated the association between irritability and sleep disturbances, indicating that sleep disturbances were significantly associated with irritability only in children with moderate to severe sensory sensitivities.

CONCLUSION

We suggest that the three symptom domains may interact and exacerbate each other such that successful intervention in one symptom domain may have positive impact on the others. Further intervention studies testing this hypothesis are highly warranted.

The importance of comprehensive support based on the three pillars of exercise, nutrition, and sleep for improving core symptoms of autism spectrum disorders

Autism spectrum disorder (ASD) is classified as a neurodevelopmental disorder. The Diagnostic and Statistical Manual of Mental Disorders (DSM)-V, which first described ASD, lists persistent deficits in social communication and interrelationships, as well as limited and recurrent modes of behavior, interests, and activities as diagnostic items. Until recently, understanding the pathophysiology of ASD has been mostly from a neurophysiological perspective, and interventions have been mostly behavioral and psychological. In recent years, however, it has become clear that ASD also affects many bodily systems, including the immune system, the sensorimotor system, and the gut-brain axis, and that these factors simultaneously influence it. In light of this background, a new "connectivome theory" has been proposed as a hypothesis for understanding ASD. "Exercise," "nutrition," and "sleep," which are discussed in this mini-review, have a particularly strong relationship with the immune, musculoskeletal, and gut systems among the pathologies mentioned in the "connectivome theory," furthermore, many reports suggest improvements in stereo-responsive behavior and social and communication skills, which are the core symptoms of ASD. In addition, these interventions are characterized by being less subject to location and cost limitations and excel in the continuity of therapeutic intervention, and the three interventions may have a reciprocal positive impact and may function as three pillars to support ASD.

Evaluation of the Relationship of Sleep Disturbances to Severity and Common Behaviors in Autism Spectrum Disorder

Background

Autism spectrum disorder (ASD) is one of the most puzzling disorders of childhood. Recent research of comorbidities that accompany ASD and are commonly attributed to the diagnosis, indicate that they may contribute to the severity of behavioral symptoms of the disorder.Disturbed sleep in all children can decrease cognition, decrease focus, increase performance problems, and alter mood and behavior. Children with ASD experience an increased sensitivity to disturbed sleep that may increase the severity of the disorder. Disturbed sleep patterns, such as increased sleep latency, nighttime waking and early arousal, have been identified in up to 80% of children with ASD. This study explored the relationship of disturbed sleep and the severity of the core ASD symptoms.

Methods

Actigraphy and an accompanying sleep diary captured disturbed sleep patterns in 24 children, ages 6-12, with ASD. Participants wore a GT3X actigraphy monitor for 7 nights to collect data on patterns of disturbed sleep. Parents completed a sleep diary and the Autism Spectrum Rating Scale (ASRS) questionnaire.A descriptive analysis was used to report the characteristics of nighttime sleep and sleep efficiency as well as sleep disturbances. Pearson's r determined the relationships between the number of sleep disturbances and the severity of ASD behavioral scores and diagnostic severity (determined by the ASRS).

Results

Of the 24 study participants, almost 92% had one or more sleep disturbances. A positive correlation was present between the number of sleep disturbances and the severity of delays in social and communication symptoms. A moderate effect size was found between the number of sleep disturbances and unusual behaviors in ASD suggests a possible, unanticipated, inverse relationship.

Conclusions

Exploring the relationship of disturbed sleep to behavior and symptom severity in children with ASD can provide an understanding of how poor sleep influences ASD symptoms. This study identified distinct differences in ASD symptom severity between and within individual participants and found unique, and unexpected, symptom patterns. This finding supports the need, in research and treatment, to identify comorbidities and symptoms that contribute to individual behavioral profiles and phenotypes of the disorder.

Sleep disturbances and emotional dysregulation in young children with autism spectrum, intellectual disability, or global developmental delay

OBJECTIVE

Sleep disturbance and emotional dysregulation (ED) are common and often functionally impairing in young children with neurodevelopmental disorders (NDD). This study investigated the relationship between sleep disturbance and ED in a sample of preschoolers with ASD, intellectual disability, or global developmental delay, and examined possible predictors of their persistence over time.

METHODS

All children under 6 years of age clinically referred between July 2018 and May 2022 to two neuropsychiatric specialized centers for NDD received a comprehensive diagnostic evaluation, including the Child Behavior Checklist 1.5-5 (CBCL), the Autism Diagnostic Observation Schedule-2 (ADOS-2), and standardized tests of cognitive and global development. Sleep disturbances were assessed with the CBCL-sleep score, and ED with the CBCL Attention, Aggression, and Anxious/Depressed scales (CBCL-AAA). A reassessment of sleep and ED was conducted after 6 months or longer, including the Child Sleep Habits Questionnaire (CSHQ). Multivariate analyses and mixed linear regression models were conducted.

RESULTS

A total of 136 children, 75.7% male, median age 38.27 months, IQR 15.39, 41.2% with global developmental disorder (GDD) or intellectual disability (ID) participated in the study. Of them, 64.7% were diagnosed with autism spectrum disorder (ASD) and 35.3% with other NDD (w/o ASD). Sleep disturbances (CBCL-Sleep) and ED (CBCL-AAA) were positively correlated (p < 0.001), after accounting for age, ID/GDD and autism symptom severity, in both the entire sample and separately in each diagnostic group (ASD and NDD w/o ASD). Seventy-five children (55%) were reassessed a mean 17.2 months afterwards. There was persistence of the positive correlation between sleep problems and ED (p < 0.001) in both the entire sample and each diagnostic group. The longitudinal mixed linear model showed that ED at follow-up was predicted by baseline sleep problems (p = 0.008), ED (p < 0.001), and ASD severity (p = 0.015).

CONCLUSIONS

Sleep disturbances are significantly associated with ED in young children with NDD, either with or without ASD, both cross-sectionally and prospectively over time. Sleep problems represent an important comorbidity and a potential treatment target for improving emotional stability in NDD.

Interventions to Support Participation in Sleep for Autistic Children and Adolescents (2013-2021)

Systematic Review Briefs provide a summary of the findings from systematic reviews developed in conjunction with the American Occupational Therapy Association's Evidence-Based Practice Program. Each systematic review brief summarizes the evidence on a theme related to a systematic review topic. This systematic review brief presents findings from the systematic review on interventions to support participation in sleep for autistic1 children and adolescents (birth to 18 yr).

Sleep problems in autism: Sex differences in the school-age population

Clinically significant sleep problems affect up to 86% of the autistic population in school-age. Sleep problems can have negative impacts on child cognition, behavior, and health. However, sex differences in the prevalence and types of sleep problems are not well understood in autism. To evaluate sex differences in sleep problems in the school-age autistic population, we obtained parent-report of sleep problems on the Children's Sleep Habits Questionnaire and conducted direct assessments to establish diagnosis and intellectual ability in 6-12-year-old children (autism n = 250; typical development [TD] n = 114). Almost 85% of autistic females demonstrated sleep problems compared to 65.8% of autistic males, 44.8% of TD females, and 42.4% of TD males; a statistically significant increase for autistic females. Autistic females demonstrated increased bedtime resistance, sleep anxiety, and sleepiness, and decreased sleep duration, but did not differ in sleep onset delay, night wakings, parasomnias, or disordered breathing compared with autistic males. Intellectual ability was not related to increased sleep problems. Higher anxiety scores were associated with more sleep problems for males but not females. In one of the first studies to evaluate sex differences in sleep in the school-age, autistic population, autistic females demonstrated increased sleep problems compared to autistic males, TD females, and TD males. Current autism assessment and intervention practices may benefit from increased attention to sleep problems in autistic school-age females and to anxiety in autistic males to enhance well-being and behavioral and health outcomes.

Sleep mediates the relationship between having an autistic child and poor family functioning

Sleep is an important biological necessity, a lack of which can have many cognitive, psychological, social, and physical impacts. Children with autism are known to present with sleep difficulties more frequently than their typically developing peers but despite this, there is relatively little research looking at the impact of sleep on the family. To investigate the effect of sleep on families of autistic and typically developing (TD) children, we conducted a study of sleep disturbances among children, sleep quality of their parents in association with their family function. In our study, 239 parents of autistic children and 227 parents of TD children participated. These parents completed a survey about their child's sleep disturbances, their own sleep quality, and their family function, along with a series of demographic questions. Analyses indicated that autistic children experience more sleep difficulties than TD peers, that children's sleep disturbances are associated with parental sleep quality and that parents of autistic children report decreased sleep quality compared to parents of TD children. Parental sleep quality, and child sleep quality were both found to partially mediate the relationship between autism diagnosis and family function.

Clinical efficacy and safety of intravenous ferric carboxymaltose treatment for restless legs symptoms and low serum ferritin in children with autism spectrum disorder

BACKGROUND

Restless legs syndrome (RLS) may be underdiagnosed in children with autism spectrum disorder (ASD) due to difficulty expressing the symptoms in their own words. In addition, administration of oral iron may be particularly difficult in children with ASD.

METHODS

This was a retrospective, open-label case series of children with ASD, restless legs (RL) symptoms, and serum ferritin <30 μg/L, who either had failed or did not tolerate oral iron, and were subsequently treated with intravenous (IV) ferric carboxymaltose (FCM). Patients received a single dose of IV FCM, 15 mg/kg up to a maximum dose of 750 mg. Data collected pre- and eight weeks post-infusion included presenting symptoms, serum ferritin, iron profile, and Clinical Global Impression Scale (CGI-Severity pre- and CGI-Improvement post-infusion). Adverse effects were assessed.

RESULTS

Nineteen children, 4-11 years old (12 male, median age 6, interquartile range (IQR 4-11) were included. A definite RLS diagnosis was identified in 6 verbal children (31.6%). RL symptoms (designated probable RLS) in the 13 other children met all RLS diagnostic criteria except "improvement of symptoms with movement," which was not definitively determined. Baseline median values were: ferritin 10 μg/L (IQR 10-16), iron 66.5 μg/dL (IQR 57-96), TIBC 382 μg/dL (IQR 360-411) and transferrin saturation 19% (IQR 14-28). Median CGI-S was 4 (moderate symptoms) (IQR 3-4). At eight weeks after IV FCM, all measures were improved. Median ferritin was 68 μg/L (IQR 62.5-109, p < 0.00045). Median CGI-I was 1 (very much improved) (IQR 1-2). All children meeting definite RLS criteria improved. Three children in the probable RLS group did not improve. Children meeting the full RLS criteria had lower baseline ferritin levels than those with a probable diagnosis (9 μg/L, IQR 9-10 vs. 13 μg/L, IQR 10-16, Mann-Whitney test p < 0.045). Adverse effects included lightheadedness, gastrointestinal discomfort, fever, and headache among others.

CONCLUSIONS

The majority of children (84.2%) with ASD, restless legs symptoms, and serum ferritin <30 μg/L had clinical improvement and significantly better serum iron parameters after a single IV FCM infusion. Although larger, randomized trials are needed, IV FCM appears to be a promising treatment for this subset of children with ASD.

Children with neurodevelopmental disorders: how do they sleep?

PURPOSE OF REVIEW

In this review we summarized the available evidence on sleep disorders in children with neurodevelopmental disorders (NDDs) in particular: intellectual disability (including some genetic conditions such as Prader-Willi Syndrome, Smith-Magenis Syndrome), Autism spectrum disorder, attention-deficit/hyperactivity disorder (ADHD), Developmental Coordination Disorder, language disorders, and specific learning disorders.

RECENT FINDINGS

Children with NDDs frequently suffer from sleep disturbances, with a higher prevalence than that of the general pediatric population.

SUMMARY

These problems tend to be chronic and may cause additional cognitive and behavioral difficulties, often affecting the whole family's well-being. Sleep behaviors are also related to other important developmental skills, such as attention and listening. Investigating sleep disorders in children with NDDs is therefore crucial in clinical practice. For a systematic approach in clinical practice, we propose the use of a short and easy to remember sleep screening tool.

Examining factors associated with sleep quality in parents of children 4-10 years with autism spectrum disorder

PURPOSE

Parents of children with autism spectrum disorder often report poorer sleep compared to parents of typically developing children. When parents do not obtain enough quality sleep, functioning may be compromised placing the onus of care on already stressed parents. However, improving sleep duration may not improve sleep quality and is not always feasible. This study aimed to measure sleep quality in parents of children with autism spectrum disorder, determine if stress and children's sleep are associated with sleep quality and whether resources, appraisals, and coping moderate these relationships.

MATERIALS AND METHODS

Multivariable regression was used to determine the effects of stress and children's sleep problems on sleep quality and test modifying effects.

RESULTS

Mean (SD) Pittsburgh Sleep Quality Index scores was 8.81 (3.76), with 77.6% of parents scoring above the clinical cut-off. Mean (SD) Children's Sleep Habits Questionnaire scores was 54.03 (8.32), with 96.3% of parents rating their child's sleep above the clinical cut-off. Children's sleep was the only significant predictor and none of the expected effect modifiers were significant.

CONCLUSION

Children's sleep may be an important target to improve parent sleep quality but requires systematic assessment with interventional research. Implications for rehabilitationBoth parents and their 4-10-year-old children with ASD experience high levels of sleep disturbances.Clinicians can start the conversation early with parents about their children's sleep by providing them with information to increase awareness and recognize healthy sleep habits in their children.Clinicians are important in the assessment, management, and evaluation of pediatric sleep problems, which may have significant spillover effects on parents of children with ASD.There is a need for more resources and training to be available to clinicians to assess children and their parents for sleep problems, which could extend beyond the assessment of sleep and consider parent's daytime functioning and mental health.

Sleep Disturbance Scale for Children: Italian Validation in Autism Spectrum Disorder Population

Sleep disorders in children with autism spectrum disorders (ASDs) are well-described. However, there is a lack of specific assessment tools to investigate sleep disturbance in this target population. The present investigation reports the Italian validation of the Sleep Disturbance Scale for Children (SDSC) in the ASD population, also investigating the correlation between sleep disorders In both children and parents. Internal consistency and test−retest reliability were investigated using Cronbach’s alpha and intraclass correlation coefficient (ICC), respectively. Concurrent validity was analyzed by comparing the score of the SDSC with the Pittsburgh Sleep Quality Index (PSQI), while the correlation between the SDCS score and the General Sleep Disturbance Scale (GSDS) was used to analyze the correlation between sleep disorders in children and sleep disorders in their parents. In total, 99 children with a diagnosis of ASD participated in the study. Cronbach’s alpha revealed satisfactory value (0.853), as well as reliability (ICC 0.972) and concurrent validity (0.745). Our results also revealed a significant linear correlation between children’s and parents’ sleep disorders (p < 0.05). In conclusion, we found the SDSC to be a useful tool for measuring sleep disorders in ASD children. Our findings offer concrete inputs to achieve adequate pathways for taking care of children with ASDs and their parents.

Copy number variation at the 22q11.2 locus influences prevalence, severity, and psychiatric impact of sleep disturbance

BACKGROUND

Sleep disturbance is common, impairing, and may affect symptomatology in developmental neuropsychiatric disorders. Here, we take a genetics-first approach to study the complex role of sleep in psychopathology. Specifically, we examine severity of sleep disturbance in individuals with a reciprocal copy number variant (CNV) at the 22q11.2 locus and determine sleep's effect on psychiatric symptoms. CNVs (deletion or duplication) at this locus confer some of the greatest known risks of neuropsychiatric disorders; recent studies suggest the 22q11.2 deletion negatively impacts sleep, but sleep disruption associated with 22q11.2 duplication has not been investigated.

METHODS

We compared subjective sleep disturbance and its relationship to psychiatric symptoms cross-sectionally and longitudinally over 1 year in 107 22q11.2 deletion (22qDel) carriers (14.56±8.0 years; 50% male), 42 22q11.2 duplication (22qDup) carriers (16.26±13.1 years; 54.8% male), and 88 age- and sex-matched controls (14.65±7.4 years; 47.1% male). Linear mixed models were used to compare sleep disturbance, assessed via the Structured Interview for Psychosis-Risk Syndromes (SIPS), across groups. Next, CNV carriers were categorized as good or poor sleepers to investigate sleep effects on multiple neurobehavioral traits: psychosis-risk symptoms (SIPS), autism-related behaviors (Repetitive Behavior Scale (RBS) and Social Responsiveness Scale (SRS)), real-world executive function (Behavior Rating Inventory of Executive Function (BRIEF)), and emotional/behavioral problems (Child Behavior Checklist (CBCL)). Linear mixed models tested the effect of sleep category and a group-by-sleep interaction on each measure, cross-sectionally and longitudinally.

RESULTS

22qDel and 22qDup carriers both reported poorer sleep than controls, but did not differ from each other. Cross-sectionally and longitudinally, poor sleepers scored higher on positive symptoms, anxious/depressed, somatic complaints, thought problems, and aggressive behavior, as well as RBS and SRS total scores. There were significant group-by-sleep interactions for positive symptoms and the majority of CBCL subdomains, in which the difference between good and poor sleepers was larger in 22qDel compared to 22qDup.

CONCLUSIONS

Our findings indicate that CNVs at the 22q11.2 locus impact sleep which, in turn, influences psychopathology. Sleep disturbances can differentially impact psychopathology, depending on 22q11.2 gene dosage. Our findings serve as a starting point for exploring a genetic basis for sleep disturbance in developmental neuropsychiatric disorders.

Sleep Problems and 6-Sulfatoxymelatonin as Possible Predictors of Symptom Severity, Adaptive and Maladaptive Behavior in Children with Autism Spectrum Disorder

In children with autism spectrum disorder (ASD), sleep disturbances are a frequent comorbidity with an adverse effect on their behavior and functioning. It was suggested that melatonin deficit is at least partly responsible for the sleep problems. The study aimed to investigate, in a sample of 56 children with ASD aged 2.8–13.3 years, if the sleep problems and melatonin secretion can serve as predictors of adaptive functioning and severity of the ASD core symptoms. We demonstrated that, after adjustment for age, the Sleep score assessed by the Children’s Sleep Habits Questionnaire predicts the Adaptive behavior composite score only in children younger than 6 years, and the preferred predictive model is for the domain Socialization. The age-adjusted Sleep score predicted Externalizing and Internalizing maladaptive behavior, with a near-zero contribution of age to the relationship between the Internalizing maladaptive behavior and Sleep score. After adjustment for age, the reduced night-time melatonin secretion predicted a higher severity of ASD symptoms in the domain Social affect and the Calibrated Severity Score, but not the sleep problems. Our results emphasize the importance of assessing sleep problems as a modifiable predictor of behavior in children with ASD and support the hypothesis about the role of melatonin in pathophysiology of ASD.

What do parents of children with autism spectrum disorder think about their quality of life? A qualitative study

BACKGROUND

Living with children with autism spectrum disorder (ASD) can affect different aspects of parents' physical and mental health and quality of life. This study aimed to identify parents' perceptions of their quality of life and factors influencing such perceptions and investigate how they cope with difficulties in their daily lives.

MATERIALS AND METHODS

This study was conducted using a qualitative research design to gain insight into how children with ASD may influence their parents' quality of life. A total of 31 parents and school counselors were selected by the snowball sampling method in autism schools in Tehran in the academic year 2018-2019. Semi-structured interviews were used to collect the data. Each interview was held based on a preprepared guideline by the researchers. In-depth questions were also asked as needed. Finally, the data were analyzed using the content analysis approach.

RESULTS

The participants reported a variety of difficulties and crises to cope with in their daily lives. The factors reported to decrease the quality of life were categorized into six main themes and 20 subthemes. The main themes included "family interactions," "parenting," "daily living," "health," "financial issues," and "community-related."

CONCLUSIONS

Due to the diversity and multilevel factors affecting the quality of life of parents having children with ASD, it is essential to adopt a comprehensive approach with the participation of all stakeholders in the development, design, and implementation of future interventions.

The Effect of Sleep-Wake Routines on the Negative Emotional States and Aggressive Behaviors in Adults with Autism Spectrum Disorders (ASD) during the COVID-19 Outbreak

Disruption in routine may be related to experiencing negative emotional states and to aggressive behaviors in individuals with Autism Spectrum Disorder (ASD). The lockdown because of COVID-19 contributed to the disruption of individuals’ routines, including the sleep−wake cycle. The current study tested a relationship between the adherence to the sleep−wake routine and aggressive behaviors via the mediation role of negative emotional states (i.e., anxiety and anger). Forty-three parents of adults with ASD completed a web-based questionnaire about their life condition during the first lockdown (April−May 2020). Preliminary analyses showed a worsening in the adults’ aggressive behaviors during the lockdown in comparison to before it (Z = −3.130; p = 0.002). In the mediation models, the relationship between the adherence to the sleep−wake routines and aggressive behaviors was significant. The models showed the hypothesized mediated relationships among the adherence to the sleep−wake routines, negative emotional states, and aggressive behaviors (Model 1: F (1, 41) = 10.478, p < 0.001; Model 2: F(1, 41) = 9.826, p = 0.003). The findings confirmed the potential protective role of the adherence to the sleep−wake routines for the emotional and behavioral adjustment of adults with autism. Theoretical and practical contributions of the study were discussed; indeed, our results may inform parent-coaching as well as intervention programs for individuals with ASD given that adequate sleep hygiene may contribute to improvements in internalizing/externalizing behaviors.

The role of probiotics in children with autism spectrum disorders: A study protocol for a randomised controlled trial

Background

Autism spectrum disorder (ASD) is a neurological and developmental condition that begins in infancy or earlier and lasts through the individual’s lifetime. The aetiology and mechanisms of ASD are not yet fully understood, and current treatment comprises mainly education and rehabilitation, without significant improvement in the core symptoms. Recent studies suggest that microbiota change in children with ASD after the ingestion of probiotics may improve the balance of microbiota and thus ASD symptoms.

Objective

The objectives of this study are to evaluate the efficacy of probiotics on the symptoms of children with ASD and the possible mechanisms involved.

Methods

This is a prospective controlled trial. A total of 160 children with ASD will be stratified and allocated to placebo and probiotics groups randomised according to the severity of their ASD symptoms. The probiotics group will be given probiotics supplements orally twice a day for 3 months and the control group will be given a placebo at the same amount, in addition to the baseline therapy of education and rehabilitation. All the children will be evaluated systematically by using different scales, questionnaires before, during, and after 3 months’ treatment, as well as 3 months after discontinuation. The potential impact of probiotics on immunity and inflammation, metabolism, and metagenome will also be investigated.

Discussion

Our previous study showed that the abundance of intestinal flora was greatly different in children with ASD, and that Bifidobacterium was associated with the severity of ASD. In the present study, we will investigate the impact of probiotics supplementation on the symptoms of Children with ASD, with the purpose of evaluating the possible therapeutic effects of additives on ASD and of providing a reference for clinical treatment. The results will help to disclose as yet unknown relationship between probiotics and ASD.

Trial registration

This study has been registered with Chinese Clinical Trial Registry (ChiCTR-2000037941).

Examining the Relationship Between Sleep Quality, Social Functioning, and Behavior Problems in Children with Autism Spectrum Disorder: A Systematic Review

Over forty percent of autistic children experience poor sleep quality, and social interaction difficulties are a core characteristic of autism. However, the relationship between sleep quality and social functioning and behavior remains poorly understood. This systematic review examined the evidence concerning the impact of sleep quality on the social functioning and behavior problems in autistic children and adolescents. It also identified key related factors and evaluated how this issue has been researched to date. Seven key journals were hand-searched and five databases were systematically searched, using keywords. Titles and abstracts of 4123 items were screened against eligibility criteria by two researchers. Relevant studies were retained if they were peer-reviewed empirical papers, published in English between 2000 and 2021. Then, the full text of 97 papers was screened and if they met the eligibility criteria, their reference lists were hand-searched. Forty-six studies were included in the final review. Data were systematically extracted and two authors critically appraised the strengths and weaknesses of studies using Critical Appraisal Skills Programme tools. Key themes were identified, because a meta-analysis was not possible due to the studies' heterogeneity. The review identified that sleep quality and social functioning are associated with one another and there is a small amount of evidence that a bi-directional causal relationship may exist. Evidence suggests that several nights of suboptimal sleep duration and a lack of deep continuous sleep negatively impact externalizing and internalizing behavior. Sleep quality is also reduced by anxiety and sensory sensitivity. However, longitudinal studies with larger samples are needed to establish causality. Future research needs to examine confounding factors and to develop consensus regarding best-practice processes for the objective measurement of sleep with autistic children. Additional research also needs to further examine the consequences of poor sleep quality on internalizing behavior, and the impact of socio-cultural practices.

Sleep Disturbances in Children Affected by Autism Spectrum Disorder

BACKGROUND

Sleep disturbances are common in children affected by Autism Spectrum Disorder (ASD). The aim of our study was to describe sleep characteristics and disturbances in children with ASD, to evaluate possible related factors, and to assess parental stress.

METHODS

Hundred children with a diagnosis of ASD (mean age: 66.7 months, SD: 27.4, range: 24.7-152.1 months, n = 79 males) were included in the study. We collected data on sociodemographic, clinical, genetic and instrumental variables as well as comorbid conditions. Parents filled out the Questionnaire on sleep behavior in the first years of life, the BEARS questionnaire, and the Parenting Stress Index Short Form. From the analysis on sleep characteristics, we excluded 25 children treated with melatonin.

RESULTS

Fifty-seven (57%) out of 100 children met the criteria for insomnia. Sleep disorders were associated with developmental or cognitive delay, emotional and behavioral problems (such as anxiety problems and aggressive behaviors) and absence of strategies for inducing sleep after nocturnal awakenings. From parents' reports, sleep disorders had diurnal repercussions on their offspring; however, we found no statistical correlation between disturbances and family stress. Also, no significant correlation was found between sleep disturbances and epilepsy. Finally, a statistical correlation was found between the regular intake of melatonin and the resolution of insomnia.

CONCLUSIONS

Multifactorial variables may be associated to insomnia that could have an impact on the children' behavior. Clinicians need to be aware of the value of screening for sleep disturbance in children with ASD to integrate sleep interventions in the treatment plan.

Impact of COVID-19 lockdown on sleep in children with autism spectrum disorders

STUDY OBJECTIVES

The impact of the COVID-19 outbreak on sleep of participants with autism spectrum disorder (ASD) was assessed.

METHODS

Parents of 111 children and adolescents with ASD filled out an anonymous online survey shared via social media, investigating the sleep patterns and disturbances before and during the lockdown.

RESULTS

The lockdown changed significantly the bedtime on weekdays in 57.8% of participants with ASD (56.9% delayed; 0.9% advanced) and the rise time in 69.2% (61.7% delayed and 7.5% advanced). Sleep duration varied on weekdays in 49.1% (24.1% increased; 25% decreased). During the lockdown, participants with ASD showed a significant increase of sleep disturbances, compared to the preceding period, especially falling asleep (35.1% vs 22.5%), anxiety at bedtime (22.5% vs 10.8%), sleep terrors (5.4% vs 0%), and daytime sleepiness (14.4% vs 3.6%).

CONCLUSIONS

Lockdown affected sleep of patients with ASD, showing an increase of difficulty in falling asleep, anxiety at bedtime, sleep terrors, and daytime sleepiness. The outbreak of COVID-19 significantly worsened sleep disturbances of children with ASD.

Effects of Washed Fecal Bacteria Transplantation in Sleep Quality, Stool Features and Autism Symptomatology: A Chinese Preliminary Observational Study

PURPOSE

Autism spectrum disorder is a highly complex neurological and psychosocial disorder characterized by social dysfunction, severe reduction in speech, and a single stereotyped behavior. The treatment methods are currently limited, and children with autism generally suffer from constipation and sleep disorders. It is urgent to find an alternative psychotropic drug, given the drug dependence and adverse reactions that may occur with long-term medication.

PATIENTS AND METHODS

This retrospective study included 49 children with autism at the first affiliated Hospital of Guangdong Pharmaceutical University, who received washed fecal microbiota transplantation (WMT) treatment between June 2019 and July 2021 and compared the sleep disorder scores between the constipation group, control group and blank group.

RESULTS

Second WMT could significantly improve the sleep disorder scores in the constipation group (p=0.026) and the decrease in sleep disturbance scale for children (SDSC) score was synchronized with the increase in Bristol stool form scale (BSFS) score. However, there was no significant difference between patients without constipation (p=0.54), and the behavior of autism improved in both groups.

CONCLUSION

WMT could relieve constipation and improve sleep disorders in children with autism, with no deterioration in stool morphology and sleep disorders in other children. Moreover, there were no obvious serious adverse clinical events after WMT.

Sleep disturbances in children newly enrolled in elementary school are associated with parenting stress in China

OBJECTIVE

This study aimed to investigate the prevalence of children's sleep disturbances among students newly enrolled in elementary school, and explored the association between the two during the child's transition from kindergarten to elementary school.

METHODS

In 2019, a cross-sectional study was conducted among 1,510 newly enrolled school kids and their parents in Beijing. Children's sleep characteristics were evaluated using the Children's Sleep Habits Questionnaire (CSHQ), and parenting stress characteristics were assessed with the Parenting Stress Index-Short Form (PSI-SF). Logistic regression models were used to analyze the association between children's sleep and parenting stress.

RESULTS

A total of 77.9% of children newly enrolled in elementary school had sleep disturbances and 15.6% of parents had experienced parenting stress. When examining the relationship between children's sleep disturbances and parenting stress, monthly family income over US$1,550 was a protective factor and children with sleep disturbances were associated with higher risk of parenting stress. Two subscales from the CSHQ were associated with higher parenting stress risk: sleep duration and daytime sleepiness. Similarly, parents experiencing parenting stress had children with higher risk of sleep disturbances. This risk was also higher for children from parents screening positive in the PSI-SF subscales for parental distress and difficult child.

CONCLUSIONS

We found that children's sleep disturbances and parenting stress were common and there was a bidirectional association between the two during this transition time. Schools and communities need to provide timely psychological support for children and parents to address major stressors.

Autism Spectrum Disorder and Intellectual Disability: A Pilot Study Exploring Associations between Child Sleep Problems, Child Factors and Parent Factors

Sleep problems are common in children with autism spectrum disorder (ASD). However, few studies have undertaken group comparisons of sleep profiles and factors associated with poorer sleep between children with ASD without intellectual disability (ID; hereafter referred to as ASD) and ASD with co-occurring ID (hereafter referred to as ASD + ID). This study aimed to (1) compare child (sleep problems and emotional and behavioural problems (EBPs)) and parent factors (parenting stress and mental health) for children with ASD compared to children with ASD + ID, and (2) examine the associations between sleep problems and child and parent factors in both groups. Parents of 56 children with ASD (22 ASD, 34 ASD + ID) aged 6–13 years took part in the study. No statistically significant differences in sleep problems were found between children with ASD compared to children with ASD + ID. However, total EBPs were independently associated with child sleep problems in both groups. Further, ‘Self-Absorbed’ and ‘Communication Disturbance’ EBPs were significantly greater in the ASD + ID compared to the ASD group. Overall treatment outcomes for children with ASD may be further improved if consideration is given to the specific types of EBPs being experienced by the child and their association with sleep problems.

Circadian Sleep-Activity Rhythm across Ages in Down Syndrome

Across all ages, individuals with Down syndrome (DS) experience high rates of sleep problems as well as cognitive impairments. This study sought to investigate whether circadian rhythm disruption was also experienced by people with DS and whether this kind of sleep disorder may be correlated with cognitive performance. A cross-sectional study of 101 participants (58 with DS, 43 with typical development) included individuals in middle childhood (6–10 years old), adolescence (11–18 years old), and young adulthood (19–26 years old). Sleep and markers of circadian timing and robustness were calculated using actigraphy. Cognitive and behavioral data were gathered via a novel touchscreen battery (A-MAP^TM, Arizona Memory Assessment for Preschoolers and Special Populations) and parent questionnaire. Results indicated that children and adolescents with DS slept the same amount as peers with typical development, but significant group differences were seen in phase timing. The circadian robustness markers, interdaily stability and intradaily variability of sleep-wake rhythms, were healthiest for children regardless of diagnostic group and worst for adults with DS. Amplitude of the 24-h activity profile was elevated for all individuals with DS. In analyses of the correlations between sleep quality, rhythms, and cognition in people with DS, interdaily stability was positively correlated with reaction time and negatively correlated with verbal and scene recall, a finding that indicates increased stability may paradoxically correlate with poorer cognitive outcomes. Further, we found no relations with sleep efficiency previously found in preschool and adult samples. Therefore, the current findings suggest that a thorough examination of sleep disorders in DS must take into account age as well as circadian robustness to better understand sleep-cognitive correlations in this group.

Subjective and Electroencephalographic Sleep Parameters in Children and Adolescents with Autism Spectrum Disorder: A Systematic Review

Background: Sleep problems have commonly manifested in children and adolescents with autism spectrum disorder (ASD) with a complex and multifactorial interaction between clinical and etiological components. These disorders are associated with functional impairment, and provoke significant physical and mental affliction. The purpose of this study is to update the existing literature about objective and subjective sleep parameters in children and adolescents with ASD, extrapolating information from polysomnography or sleep electroencephalography, and sleep related questionnaires. Methods: We have conducted a systematic review of case-control studies on this topic, performing a web-based search on PubMed, Scopus and the Web of Science databases according to the Preferred Reporting items for Systematic Review and Meta-analyses (PRISMA) guidelines. Results: Data collected from 20 survey result reports showed that children and adolescents with ASD experienced a higher rate of sleep abnormalities than in typically developing children. The macrostructural sleep parameters that were consistent with subjective parent reported measures unveil a greater percentage of nighttime signs of insomnia. Sleep microstructure patterns, in addition, pointed towards the bidirectional relationship between brain dysfunctions and sleep problems in children with ASD. Conclusions: Today’s literature acknowledges that objective and subjective sleep difficulties are more often recognized in individuals with ASD, so clinicians should assess sleep quality in the ASD clinical population, taking into consideration the potential implications on treatment strategies. It would be worthwhile in future studies to examine how factors, such as age, cognitive level or ASD severity could be related to ASD sleep abnormalities. Future research should directly assess whether sleep alterations could represent a specific marker for atypical brain development in ASD.

Pediatric prolonged-release melatonin for insomnia in children and adolescents with autism spectrum disorders

Introduction: Insomnia is common among children and adolescents with Autism spectrum disorder (ASD). The first drug licensed for insomnia in this population, a pediatric-appropriate prolonged-release melatonin (PedPRM) formulation is described.Areas covered: Literature search on  PedPRM efficacy and safety profile in clinical trials, and a proposed decision-making algorithm to optimize outcome  in the treatment of insomnia in children and adolescents with ASD.Expert opinion: PedPRM treatment effectively improves sleep onset, duration and consolidation, and daytime externalizing behaviors in children and adolescents with ASD and subsequently caregivers' quality of life and satisfaction with their children's sleep. The coated, odorless and taste-free mini-tablets are well-accepted in this population who often have sensory hypersensitivity and problems swallowing standard tablet preparations. The most frequent long-term treatment-related adverse events were fatigue (6.3%), somnolence (6.3%), and mood swings (4.2%) with no evidence of delay in height, BMI, or pubertal development, or withdrawal effects. The starting dose is 2 mg once daily independent of age or weight, escalated to 5-10 mg/day if predefined treatment success criteria are unmet. Slow melatonin metabolizers (~10% of children), may require lower doses. Given its long-term efficacy, safety and acceptance, PedPRM may ameliorate long-term consequences of insomnia in this population.

Promoting Sleep and Balanced Screen Time among School-Aged Children with Neurodevelopmental and Mental Health Disorders: A Parent Perspective

Background: Children with neurodevelopmental and mental health disorders (N/MHD), such as autism spectrum, mood disorders, and anxiety, are more likely to engage in excessive screen time, receive insufficient sleep, and to have obesity than neurotypical peers. However, little is known about how parents of these children approach promoting sleep and balanced screen time. Methods: We conducted semistructured interviews with 24 parents of children aged 8-15 years with a diagnosis of N/MHD to assess barriers and facilitators to promoting sleep and balanced screen time. Interviews were transcribed, double-coded using constant comparative methods, and summarized into themes using NVivo 11. Results: Many parents described children's chronic sleep challenges, often compounded by screen use and no clear solutions. When feeling overwhelmed, some parents reluctantly reported co-sleeping or allowing gaming devices in bed. Nearly all participants reported chronic, occasionally severe, conflict when managing children's screen time, with some parents experiencing opposition and physical aggression. Parents struggled to weigh the benefits of screen use (i.e., behavior management, learning, and social connection) with the costs (i.e., reduced self-care and limited physical activity). To combat barriers, parents described firm routines (i.e., "screens off" time and consistent bedtime on weekdays and weekends), moderating access (i.e., shutting down internet and no device in bedroom), verbal priming, and coping strategies (i.e., music and books). Conclusions: Parents of children with N/MHD face unique challenges in promoting sleep and balanced screen time. Given these behaviors may impact weight status and mental health, future interventions should examine ways to support parents in reducing conflict while promoting healthy habits.

Collateral Child and Parent Effects of Function‑Based Behavioral Interventions for Sleep Problems in Children and Adolescents with Autism

This study follows McLay et al., Journal of Autism and Developmental Disorders, (2020) to investigate whether the function-based behavioral sleep interventions received by 41 children and adolescents with autism spectrum disorder (ASD) produced collateral improvements in ASD severity, internalizing and externalizing symptoms and parent relationship quality, ratings of depression, anxiety and stress, and personal sleep quality. Concomitant with reduced sleep problem severity, improvements were found in children's internalizing and externalizing behavior and ASD symptom severity. Small improvements were also found in maternal sleep quality and parental stress. There was little change in parental relationship quality post-treatment, possibly reflecting high baseline scores. Overall, collateral benefits were generally small but positive, consistent with the limited extant research, and underscore the importance of investigating collateral effects across a range of variables.

Sleep Problems of Children with Autism May Independently Affect Parental Quality of Life

The current study explored how and to what extent sleep problems in children with autism spectrum disorder (ASD) impacted their parents' quality of life (QOL). A total of 440 ASD children and 344 age-matched typically developing (TD) children were included in the case-control designed study. In the TD group, a linear regression model showed that the Children's Sleep Habits Questionnaire (CSHQ) total scores were negatively associated with maternal mental health summary (MCS) scores in the SF-36v2 (β = - 2.831), while in the ASD group, the CSHQ total scores were negatively associated with the parental physical health summary (PCS) scores (β = - 3.030 for mothers, β = - 3.651 for fathers). Path analysis showed that sleep problems in ASD children had both direct and indirect effects on maternal PCS scores. The results indicated that sleep problems in children with ASD might affect parental QOL differently from TD children, and act as independent impact factors on parental physical health.

The association of sleep quality and aggression: A systematic review and meta-analysis of observational studies

Poor sleep quality is closely related to aggression, but despite the promise of new therapeutic possibilities, a systematic synthesis of observational research on the association between sleep quality and aggression is lacking. This systematic review and meta-analysis examined the association between sleep quality and aggression, using the academic databases PubMed and PsycINFO. Subjective and objective measures of sleep quality were included, as well as multiple measures of aggression, assessing aggressive and externalizing behavior, anger, hostility and irritability. Ninety-two observational articles, containing 96 studies, encompassing a total of 58.154 children, adolescents and adults were sourced out of 7161 references identified. Methodological quality was moderate or strong in 76% of studies. Data for meta-analysis was available from 74 studies. Poorer sleep quality was associated with higher aggression in 80.8% of studies. Pooled results showed a correlation of 0.28 (95%CI 0.25-0.31; I² = 90.1%) and odds ratio of 3.61 (95%CI 1.13-11.51; I² = 88.3%). Effect estimates and heterogeneity varied according to population type and measurement instruments, but not according to article quality or age group. Our findings confirm that poor sleep quality is consistently associated with higher aggression. As most evidence is cross-sectional, more prospective and high-quality experimental evidence is required to elucidate cause-effect and optimize prevention and treatment of aggression.

Sleep disturbances in autism spectrum disorder without intellectual impairment: relationship with executive function and psychiatric symptoms

The autism spectrum disorder (ASD) is a neurodevelopmental condition, frequently accompanied by medical and psychiatric pathology. One of the most commonly found problems associated with ASD is sleep disturbances, which are estimated to affect approximately 80% of the people with ASD, not only during childhood but also in the adolescence and adult stages. Nevertheless, the relationship of these sleep difficulties with autism severity, as well as other associated impairments such as executive functioning and psychiatric disorders (eg, depression), has not yet been widely studied. The main objective of the present study was to explore the relationship between sleep disturbances, subjective measures of executive function, and psychiatric pathology in the ASD population. To reach that goal, a group of 89 participants with ASD (44 children/adolescents and 45 adults) was recruited and evaluated with self-reported measures of executive function performance and psychiatric pathology tests. Multivariate analysis showed a significant association between sleep disturbances and psychiatric symptoms in both ASD groups, with greater sleep disturbances predicting more severe psychiatric pathology. No significant association was found with executive function in any group. Limitations included a small sample size and lack of objective measures. Sleep problems seem to be associated with the severity of psychiatric pathology throughout the lifespan, increasing the chance of developing psychiatric symptoms when they were present. Improving sleep quality in ASD at all ages may result in preventing and/or decreasing psychiatric pathology in this population.

Sleep Disturbances and Sensory Sensitivities Co-Vary in a Longitudinal Manner in Pre-School Children with Autism Spectrum Disorders

Previous research has demonstrated that sleep disturbances are positively correlated with sensory sensitivities in children with ASD. Most of these studies, however, were based on cross-sectional analyses, where the relationship across symptom domains was examined at a single time-point. Here, we examined the development of 103 pre-school children with ASD over a 1–3-year period. The results revealed that spontaneous longitudinal changes in sleep disturbances were specifically correlated with changes in sensory sensitivities and not with changes in other sensory processing domains nor with changes in core ASD symptoms. These finding demonstrate a consistent longitudinal relationship between sleep disturbances and sensory sensitivities, which suggests that these symptoms may be generated by common or interacting underlying physiological mechanisms.

Differential Item Functioning Based on Autism Features, IQ, and Age on the Screen for Child Anxiety Related Disorders (SCARED) Among Youth on the Autism Spectrum

Anxiety commonly occurs among youth on the autism spectrum, yet measurement of anxiety in this population is complicated by a number of factors, including potentially overlapping symptomatology, the child's intellectual functioning, and changes in anxiety across development. Moreover, few studies have examined the psychometric properties of anxiety measures in this population, and no study to date has tested whether there are systematic differences in the measurement of anxiety, or differential item functioning (DIF), across the high degree of heterogeneity and the developmental course of autism. To test this possibility, data were combined across multiple studies using the National Database for Autism Research, an NIH-funded data repository. Parent-report on the Screen for Child Anxiety Related Disorders (SCARED) and Social Communication Questionnaire (SCQ) were used as measures of anxiety and autism features, respectively. A confirmatory factor analysis indicated good fit of the literature standard five-factor structure. Moderated nonlinear factor analysis (MNLFA) revealed multiple items with intercept and loading DIF based on level of autism features, IQ, and age, especially for items related to social behavior. Therefore, although the measure's factor structure is consistent with that found in the general population, the SCARED may not capture differences in anxiety equivalently for all children on the spectrum and across their development. Clinicians and researchers need to be especially vigilant in measuring anxiety symptoms in children with autism by removing items flagged for DIF from the SCARED and/or by using multiple measures and informants. LAY ABSTRACT: Autistic youth often experience clinical levels of anxiety. Many tools used to measure anxiety were developed for the general population, but not for use with autistic youth. This study found that the Screen for Child Anxiety Related Disorders (SCARED) measures the same five dimensions of anxiety as in the general population. Parents, however, may respond differently to questions on the SCARED based on their child's autism features, intellectual functioning, and age, which impacts our ability to accurately measure anxiety among autistic youth.

Melatonin dispensing among New Zealand children aged 0-18 years with autism: a nationwide cross-sectional study

OBJECTIVE/BACKGROUND

Sleep problems in children on the autism spectrum are prevalent and persistent. Such problems are the result of a combination of biopsychosocial factors, including abnormal melatonin secretion. Exogenous melatonin is an empirically supported and popular treatment for sleep problems. However, we know little about rates of melatonin dispensing and associated variables. This study investigated rates of melatonin dispensing and the sociodemographic and child characteristics associated with its use in New Zealand.

METHODS

This nationwide cross-sectional study used linked administrative health data obtained via the Integrated Data Infrastructure (IDI). Data were obtained for 11,202, 0-18 year old children on the autism spectrum. Descriptive data, and adjusted and unadjusted risk ratios, were calculated for sociodemographic and child characteristics.

RESULTS

Melatonin is accessed by almost one quarter of children on the autism spectrum in New Zealand, with higher observed rates among females and those aged between 5 and 11 years, of European ethnicity, and presenting with co-occurring mental health conditions.

CONCLUSIONS

Findings are largely consistent with research investigating both sleep disturbances and psychotropic drug use among children on the autism spectrum. High rates of melatonin use, age- and sex-related differences in its use, and the complexity associated with the presence of co-occurring conditions necessitates development of practice guidelines for melatonin dispensing. Further investigation into the duration of melatonin use and the interaction between child characteristics, co-occurring conditions, sociodemographic variables and melatonin dispensing is warranted.

Autism Spectrum Disorder and Sleep

Children and adolescents with autism spectrum disorder (ASD) experience sleep disturbances, particularly insomnia, at rates much higher than the general population. Daytime behavioral problems and parental stress are associated with the resultant sleep deprivation. Behavioral interventions, parental education, and melatonin are effective treatments. The epidemiology of sleep disturbances in youth with ASD is reviewed in this article as well as the latest in treatments.

Sleep Problems and Trajectories of Restricted and Repetitive Behaviors in Children with Neurodevelopmental Disabilities

Sleep problems are prevalent in children with neurodevelopmental disabilities and are associated with the expression of restricted and repetitive behaviors (RRBs). Children (n = 57) with autism spectrum disorder (ASD, n = 38) or developmental delay (DD, n = 19) participated in multiple assessments of intellectual ability, ASD symptoms, and RRBs (3 timepoints for ASD, 2 for DD). Sleep problems assessed at age 4 via parent report were associated with trajectories of higher-order RRBs (sameness/ritualistic/compulsive behaviors) from age 2-6 in the ASD group, and from age 2-4 in the DD group, even after controlling for intellectual ability, social-affective symptoms, and anxiety. Trajectories of stereotyped/restricted behaviors were unrelated to sleep problems. Sleep problems were associated with trajectories of higher-order (but not lower-order) RRBs in a transdiagnostic sample.

Associations Between Child Sleep Problem Severity and Maternal Well-Being in Children with Autism Spectrum Disorder

This study investigated whether sleep problem severity in children with autism spectrum disorder was associated with maternal well-being. Mothers of 234 children reported on their mental health (Kessler Psychological Distress Scale), parenting stress (Parenting Stress Index-4-SF), health-related quality of life (HRQoL; Assessment of Quality of Life-4D) and their child's sleep (Children's Sleep Habits Questionnaire-ASD). Analyses revealed sleep initiation and duration problem severity scores were associated with increased mental health difficulties. Specific child sleep problems were not associated with parenting stress or HRQoL. This study revealed the importance of considering sleep and the family system when assessing maternal well-being. Future research considering parent, child and family factors will be important to informing a family focused approach to mental health.

Long-term melatonin treatment for the sleep problems and aberrant behaviors of children with neurodevelopmental disorders

BACKGROUND

Clinical evidence is required about the long-term efficacy and safety of melatonin treatment for sleep problems in children with neurodevelopmental disorders (NDDs) who underwent adequate sleep hygiene interventions.

METHODS

We conducted a 26-week, multicenter, collaborative, uncontrolled, open-label, phase III clinical trial of melatonin granules in children 6 to 15 years of age who had NDDs and sleep problems. The study consisted of the 2-week screening phase, the 26-week medication phases I and II, and the 2-week follow-up phase. Children received 1, 2, or 4 mg melatonin granules orally in the medication phases. Variables of sleep status including sleep onset latency (SOL), aberrant behaviors listed on the Aberrant Behavior Check List-Japanese version (ABC-J), and safety were examined. The primary endpoint was SOL in the medication phase I.

RESULTS

Between June 2016 and July 2018, 99 children (80 males and 19 females, 10.4 years in mean age) were enrolled at 17 medical institutions in Japan-74, 60, 22, 9, 6, and 1 of whom had autism spectrum disorder, attention-deficit/hyperactivity disorder, intellectual disabilities, motor disorders, specific learning disorder, and communication disorders, respectively, at baseline. Fifteen children received the maximal dose of 4 mg among the prespecified dose levels. SOL recorded with the electronic sleep diary shortened significantly (mean ± standard deviation [SD], - 36.7 ± 46.1 min; 95% confidence interval [CI], - 45.9 to - 27.5; P <  0.0001) in the medication phase I from baseline, and the SOL-shortening effect of melatonin persisted in the medication phase II and the follow-up phase. Temper upon wakening and sleepiness after awakening improved significantly (P <  0.0001 each) in the medication phase I from baseline and persisted in the follow-up phase. The following subscales of the ABC-J improved significantly: stereotypic behavior (P = 0.0322) in the medication phase I; and irritability, hyperactivity, and inappropriate speech (P <  0.0001) in the medication phase II. Treatment-emergent adverse events did not occur subsequent to week 16 after medication onset, and NDDs did not deteriorate in the follow-up phase.

CONCLUSIONS
