Use of Ball Blanket in attention-deficit/hyperactivity disorder sleeping problems

User Experiences of Ball Blankets in Adults with Depression-Related Insomnia: A Qualitative Content Analysis Study

Insomnia is prevalent in patients suffering from depression and may itself exacerbate the disability associated with depression and impede the path to recovery. Although crucial in ensuring meaningful interactions and interventions for patients, research on patients' experiences of depression-related insomnia and its treatment is limited. The purpose of this study was therefore to investigate how adult patients with depression-related insomnia experience sleeping with a weighted Protac Ball Blanket®, focusing on how the blanket feels and works and contributes to their subjective sleep quality experience. An inductive content analysis approach was adopted. Semi-structured interviews were conducted with 13 patients. Four categories were identified: 1) Deep and dynamic touch pressure from the plastic balls induced calmness; 2) Changing sensory impressions from the rolling balls distracted attention from distressing thoughts and emotions; 3) The ball blanket improved the quality and quantity of sleep, which increased daily well-being; 4) Sleeping with the ball blanket was associated with positive as well as negative experiences depending on personal preferences for sensory stimulation. This study explains how the Protac Ball Blanket® as a potential non-pharmacological sleep-intervention improved the sleep of adult patients with depression-related insomnia. The blanket was found meaningful for coping with sleeplessness and with mental and physical unrest.

The efficacy of ball blankets on insomnia in depression in outpatient clinics: A randomised crossover multicentre trial

Many patients with depression report insomnia symptoms that profoundly affect their health and well-being. Non-pharmacological treatments of insomnia may be preferable for some patients. In this randomised crossover trial, we investigated the efficacy of the Protac Ball Blanket® on insomnia among patients with depression. Included patients (n = 45) were diagnosed with unipolar depression, and with subjective insomnia and poor sleep quality (Pittsburgh Sleep Quality Index Score > 5). Each patient slept 2 weeks with a Protac Ball Blanket® and 2 weeks with a control duvet. Randomisation defined the order of the 2-week sleep periods. Patients served as their own control in this design. The primary outcome was changes in total night-time sleep. Secondary outcomes were sleep-onset latency, number of awakenings, wake after sleep onset, daily use of pro necessitate sedatives and hypnotics, subjective sleep quality (Pittsburgh Sleep Quality Index), insomnia severity (Insomnia Severity Index), symptoms of depression (Hamilton Depression Rating Scale, Major Depression Inventory), symptoms of anxiety (Beck Anxiety Index), and patient-reported outcomes concerning interpersonal sensitivity, neurasthenia, anxiety and depression (Self-Reported Symptom State Scale). Paired two-sided t-tests were used to compare the means of the differences of the outcomes. Protac Ball Blanket® increased total night-time sleep by 12.9 min (95% confidence interval: 1.21-24.63, p = 0.031). Among the secondary outcomes, Protac Ball Blanket® decreased Hamilton Depression Rating Scale by 2.78 (95% confidence interval: -5.44; -0.11, p = 0.042) and Insomnia Severity Index by 2.98 (95% confidence interval: -5.45; -0.50, p = 0.020). No changes were observed in sleep-onset latency, number of awakenings, wake after sleep onset, Pittsburgh Sleep Quality Index, Major Depression Inventory, Beck Anxiety Index, Self-Reported Symptom State Scale, and medication use. The results suggest that some patients may benefit from Protac Ball Blanket® as an add-on non-pharmacological treatment to improve sleep in depression.

"Tell Me More About Your Child's Sleep": A Qualitative Investigation Of Sleep Problems In Children With ADHD

OBJECTIVE

To investigate parental experiences and perceptions of sleep problems in their children with Attention Deficit Hyperactivity Disorder (ADHD), the perceived impacts of sleep problems and coping strategies deployed by parents.

METHODS

Semi-structured interviews with twenty-six parents of pre-adolescent children with a diagnosis of ADHD, followed by thematic analysis of the interview transcripts.

RESULTS

Three themes were generated from the data: Children's Sleep Difficulties; Impacts of Children's Sleep; and Improving Children's Sleep. Sleep initiation problems in children with ADHD were commonly reported by parents, were perceived to be linked in a bidirectional manner with executive and emotional problems, and were reported as being disruptive to parental sleep. Some parents reported that their children's sleep problems were the initial prompt that lead to a diagnosis of ADHD. Parents reported utilizing a range of coping strategies to mitigate sleep problems, such as controlling the bedroom sensory environment and using emotional "wind down" as part of the bedtime routine. Some parents endorsed a beneficial effect of melatonin on their children's sleep.

CONCLUSIONS

Sleep problems in children with ADHD were perceived as important issues by parents. Equipping parents with evidence-based strategies for the management of their children's sleep may lead to benefits for the children, parents and wider household.

The effect of weighted blankets on sleep and related disorders: a brief review

Background

Sleep disorders such as insomnia can lead to a range of health problems. The high risk of side effects and drug abuse of traditional pharmacotherapy calls for a safer non-pharmacotherapy.

Aims

To examine the use and efficacy of weighted blankets in improving sleep and related disorders in different populations and explore the possible mechanisms.

Methods

A literature search was conducted using PubMed, Embase, Web of Science, MEDLINE, Cochrane Library and CNKI databases. Eligible studies included an intervention with weighted blankets and outcomes covering sleep and/or related disorders (behavioral disturbance, negative emotions and daytime symptoms). Studies using other deep pressure, compression, or exercise-related interventions were excluded.

Conclusions

Most of the included studies showed that weighted blankets could effectively improve sleep quality and alleviate negative emotions and daytime symptoms in patients with sleep disorders, attention deficit hyperactivity disorder, autism spectrum disorder, and other related disorders, with a possible mechanism of deep pressure touch.

Recommendations

Weighted blankets might be a promising tool for sleep interventions among individuals with sleep disorders in clinical settings. More high-quality and large-scale randomized controlled trials are needed to further validate the safety and efficacy of weighted blankets and explore precise mechanisms.

The efficacy of weighted blankets for sleep in children with attention-deficit/hyperactivity disorder-A randomized controlled crossover trial

Weighted blankets are a non-pharmacological intervention for treating sleep and anxiety problems in children with attention-deficit/hyperactivity disorder. However, research on the efficacy of weighted blankets is sparse. The aim of this randomized controlled trial with a crossover design (4 + 4 weeks) was to evaluate the efficacy of weighted blankets on sleep among children with attention-deficit/hyperactivity disorder and sleeping problems. Children diagnosed with uncomplicated Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition attention-deficit/hyperactivity disorder with verified sleep problems were randomized to start with either a weighted blanket or a lighter control blanket. Data collection was performed at weeks 0, 4 and 8 using actigraphy, questionnaires and a daily sleep diary. T-tests were used to evaluate efficacy. The study included 94 children with attention-deficit/hyperactivity disorder (mean age 9.0 [sd 2.2] years; 54 [57.4%] boys). Weighted blankets had a significant effect on total sleep time (mean diff. 7.72 min, p = 0.027, Cohen's d = 0.24), sleep efficiency (mean diff. 0.82%, p = 0.038, Cohen's d = 0.23) and wake after sleep onset (mean diff. -2.79 min, p = 0.015, Cohen's d = -0.27), but not on sleep-onset latency (p = 0.432). According to our exploratory subgroup analyses, weighted blankets may be especially beneficial for improving total sleep time in children aged 11-14 years (Cohen's d = 0.53, p = 0.009) and in children with the inattentive attention-deficit/hyperactivity disorder subtype (Cohen's d = 0.58, p = 0.016). Our results suggest that weighted blankets may improve children's sleep and could be used as an alternative to pharmacological sleep interventions.

The effectiveness of weighted blankets on sleep and everyday activities - A retrospective follow-up study of children and adults with attention deficit hyperactivity disorder and/or autism spectrum disorder

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) and Autism Spectrum Disorder (ASD) are often accompanied by sleep problems influencing social, emotional and cognitive functioning in everyday activities.

AIM

The aim of this study was to investigate whether the use of a weighted blanket has a positive impact on sleep and everyday activities in individuals with ADHD and/or ASD.

MATERIAL AND METHODS

The study included 85 individuals diagnosed with ADHD and/or ASD, 48 children aged ≤17 (57%) and 37 adults ≥18 years (44%), who were prescribed with a weighted blanket. The participants responded via a telephone interview.

RESULTS

Findings demonstrated that a weighted blanket improved abilities related to falling asleep, sleeping the whole night, and relaxing during the day. Using a weighted blanket improved morning/evening daily routine, including preparing/going to sleep and waking up in the morning.

CONCLUSIONS

Weighted blankets showed positive impact on falling asleep, sleeping the whole night, and relaxing during the day, and they were used frequently by children and adults with ADHD and/or ASD. Findings indicate that a weighted blanket improved morning/evening routine, however this research area needs further investigation using both subjective and objective parameters.

Experiences of Using Weighted Blankets among Children with ADHD and Sleeping Difficulties

Introduction

Sleeping difficulties are common in children with attention deficit hyperactivity disorder (ADHD). A sleep intervention with weighted blankets was designed to increase current understanding of using weighted blankets to target children's individual needs in connection with sleep and daytime functioning.

Aim

To explore how children with ADHD and sleeping difficulties experience the use of weighted blankets.

Methods

An explorative qualitative design in which 26 children with ADHD and sleeping difficulties, 6-15 years old, were interviewed about a sleep intervention with weighted blankets. Four categories emerged from qualitative content analysis.

Results

Children's experiences revealed that the use of weighted blankets 1) requires a commitment, by adjusting according to needs and preferences and adapting to the environment; 2) improves emotional regulation by feeling calm and feeling safe; 3) changes sleeping patterns by creating new routines for sleep and improving sleep quality; and 4) promotes everyday participation by promoting daily function and balancing activity and sleep.

Conclusions

Using weighted blankets promoted children's management of daily life with ADHD and sleeping difficulties. Occupational therapists can improve the assessment and delivery of weighted blankets tailored to individual needs based on increased knowledge from the children themselves.

Weighted Blankets' Effect on the Health of Older People Living in Nursing Homes

Background: An increasingly aging population is a global phenomenon. While considered a positive step forward, vulnerability to age-related health problems increases along with the ageing population. The aim of the study was to investigate weighted blankets’ effect on health regarding quality of life (QoL), sleep, nutrition, cognition, activities of daily living ADL and medication in older people living in nursing homes. Methods: In total, 110 older people were involved in an intervention with weighted blankets, and 68 older people completed the intervention. Measures before and after were performed regarding quality of life; QoL-AD, EQ-VAS, sleep; MISS, nutrition; MNA, cognition; S -MMSE (ADL) and medication. Comparative statistical analyses were applied. Results: After intervention with weighted blankets, health in general, such as QoL, improved. Sleep also improved significantly, especially with respect to waking up during the night. Nutrition was enhanced, health as a cognitive ability improved, and medication in the psychoanaleptic group decreased. The effect size varied between small and large. Conclusions: A weighted blanket seems to be an effective and safe intervention for older people in nursing homes, as several improvements were made regarding the health of older people.

SLEEP: intervention with weighted blankets for children with attention deficit hyperactivity disorder (ADHD) and sleep problems: study protocol for a randomised control trial

INTRODUCTION AND OBJECTIVES

Children with attention deficit hyperactivity disorder (ADHD) have an increased risk of sleep problems. Weighted blankets are one possible non-pharmacological intervention for these problems in this group of children. However, the effectiveness of weighted blankets is insufficiently investigated. This study aims to investigate the effectiveness of weighted blankets in terms of sleep, health-related outcomes and cost-effectiveness as well as to explore children's and parents' experiences of a sleep intervention with weighted blankets.

METHODS AND ANALYSIS

This study is a randomised placebo-controlled crossover trial comparing the effect of weighted fibre blankets (active) with fibre blankets without weight (control). Children aged 6-13 years, recently diagnosed with uncomplicated ADHD with verified sleep problems, were included in the study. The study period is 4 weeks for each condition, respectively, and then an 8-week follow-up. A total of 100 children diagnosed with ADHD and sleep problems will enter the study. The primary outcomes are sleep and cost per quality-adjusted life years. The secondary outcomes are health-related quality of life, ADHD symptoms, psychological distress and anxiety. Interviews with a subsample of the participating children and parents will be conducted for exploring the experiences of the intervention.

ETHICS AND DISSEMINATION

Ethical approval of the trial has been obtained from the Swedish Ethical Review Authority (number 2019--2158) and conforms to the principles outlined in the Declaration of Helsinki (WMA, 2013). Results will be reported as presentations at peer-review conferences, in articles in peer-review journals and meetings with healthcare providers.

NCT04180189.

A Systematic Review of Sleep and Circadian Rhythms in Children with Attention Deficit Hyperactivity Disorder

OBJECTIVE

Children and adults with ADHD often report sleep disturbances that may form part of the etiology and/or symptomatology of ADHD. We review the evidence for sleep changes in children with ADHD.

METHODS

Systematic review with narrative synthesis assessing sleep and circadian function in children aged 5 to 13 years old with a diagnosis of ADHD.

RESULTS

148 studies were included for review, incorporating data from 42,353 children. We found that sleep disturbances in ADHD are common and that they may worsen behavioral outcomes; moreover, sleep interventions may improve ADHD symptoms, and pharmacotherapy for ADHD may impact sleep.

CONCLUSION

Sleep disturbance may represent a clinically important feature of ADHD in children, which might be therapeutically targeted in a useful way. There are a number of important gaps in the literature. We set out a manifesto for future research in the area of sleep, circadian rhythms, and ADHD.

Feasibility trial of weighted blankets as an intervention for emergence delirium in postoperative pediatric patients

BACKGROUND

Emergence delirium (ED) is a significant problem in the post anesthesia care unit (PACU), resulting in dislodgement of medical devices, patient and staff injury, prolonged recovery, and parent dissatisfaction. Parental requests for the use of weighted blankets in the hospital setting have increased. However, while weighted blankets have shown potential as treatment for anxiety in adults and children, no studies have demonstrated their safe use with children in the hospital setting.

PURPOSE

To explore the safety of weighted blanket use with children in the PACU as an intervention for ED, a feasibility study was conducted.

DESIGN AND METHODOLOGY

A convenience sample of 93 participants, aged three to 10 years were recruited. Watcha scores, vital signs, length of wear time, and reason for blanket removal were recorded for all patients.

RESULTS

Eighty-five patients completed the study. Four participants experienced vital signs outside the defined safety parameters, with only one experiencing an adverse event (1.2%). This was consistent with the historic adverse event rate of 1% for the study site. Staff did not report issues with the use or cleaning of the blankets. Of interest, there was significant correlation between ED and suspected pain.

CONCLUSION

The study demonstrated weighted blanket use is safe and feasible with children in the hospital setting, Additional studies are needed to determine the effectiveness of weighted blankets as an intervention for ED and the impact pain may have on the severity and prevalence of ED.

Nursing staff's experiences of how weighted blankets influence resident's in nursing homes expressions of health

Purpose

The most common treatment for resident’s health problems is pharmacological. Little research has been done on how an intervention with a non-pharmacological method, such as a weighted blanket, Through the nursing staff view, we can learn how weighted blankets influence resident’s health in nursing homes. The aim of this study was to explore nursing staff’s experiences of how an intervention with weighted blankets influenced resident’s expressions of health.

Methods

The study had a descriptive qualitative design with semi-structured interviews with 20 nursing staff working in nursing homes, and an inductive content analysis was applied.

Results

The nursing staff expressed that the weighted blanket positively influenced resident’s health in the areas of sleep, physical activity, and psychological behaviour. The weighted blanket made them fall asleep faster, sleep was uninterrupted andthey felt more rested in the morning. The nursing staff observed an increased level of activity as the resident became more energetic . The nursing staff also experienced reduced negative psychological behaviours like anxiety and worrying.

Conclusion

This study indicated that the weighted blanket changed the health expression of resident in several crucial areas. Deep pressure treatment indicates an alternative health-improved treatment for resident in nursing homes.

Parents' Experiences of Weighted Blankets' Impact on Children with Attention-Deficit/Hyperactivity Disorder (ADHD) and Sleep Problems-A Qualitative Study

Sleep disturbances are common among children with attention-deficit/hyperactivity disorder (ADHD). While pharmacological treatment has increased dramatically, parents often prefer non-pharmacological interventions. Research on experiences of weighted blankets and their effect in sleep improvement is scarce. The aim of this study was to explore parents' experiences of weighted blankets for children with ADHD and sleep problems, and the impact on their children's sleep. The explorative design was based on qualitative content analysis. Interviews were conducted with a purposeful sample of 24 parents of children with ADHD and sleep problems, after completing a sleep intervention with weighted blankets for 16 weeks. Parents reported that children sleeping with weighted blankets: (1) achieved satisfactory sleep, including improved sleep onset latency, sleep continuity, and sleep routines; (2) achieved overall well-being, including improved relaxation and reduced anxiety; and (3) mastered everyday life, including improved balance in life, family function, and participation in school and leisure activities. This study brings forward novel aspects of the effects of improved sleep among children with ADHD. The findings contribute to the understanding of potential positive effects of an intervention with weighted blankets critical for clinical practice to improve sleep, well-being, and everyday life of children with ADHD and their families.

A randomized controlled study of weighted chain blankets for insomnia in psychiatric disorders

STUDY OBJECTIVES

This study aimed to evaluate the effect of weighted chain blankets on insomnia and sleep-related daytime symptoms for patients with major depressive disorder, bipolar disorder, generalized anxiety disorder, and attention deficit hyperactivity disorder.

METHODS

One hundred twenty patients were randomized (1:1) to either a weighted metal chain blanket or a light plastic chain blanket for 4 weeks. The outcome was evaluated using the Insomnia Severity Index as primary outcome measure and day and night diaries, Fatigue Symptom Inventory, and Hospital Anxiety and Depression Scale as secondary outcome measures. Sleep and daytime activity levels were evaluated by wrist actigraphy.

RESULTS

At 4 weeks, there was a significant advantage in Insomnia Severity Index ratings of the weighted blanket intervention over the light blanket (P < .001) with a large effect size (Cohen's d 1.90). The intervention by the weighted blanket resulted in a significantly better sleep-maintenance, a higher daytime activity level, and reduced daytime symptoms of fatigue, depression, and anxiety. No serious adverse events occurred. During a 12-month open follow-up phase of the study, participants continuing to use weighted blankets maintained the effect on sleep, while patients switching from a light to a weighted blanket experienced an effect on Insomnia Severity Index ratings similar to that of participants using the weighted blanket from the beginning.

CONCLUSIONS

Weighted chain blankets are an effective and safe intervention for insomnia in patients with major depressive disorder, bipolar disorder, generalized anxiety disorder, or attention deficit hyperactivity disorder, also improving daytime symptoms and levels of activity.

Safety, Feasibility, and Effectiveness of Weighted Blankets in the Care of Infants With Neonatal Abstinence Syndrome: A Crossover Randomized Controlled Trial

BACKGROUND

Nurses are caring for increasing numbers of infants diagnosed with neonatal abstinence syndrome (NAS). The recommended initial line of treatment to alleviate NAS symptoms includes nonpharmacologic interventions; however, there is little rigorous evidence on the effectiveness of nonpharmacologic interventions.

PURPOSE

The purpose of this study was to assess the safety, feasibility, and effectiveness of weighted blankets in the care of NAS infants.

METHODS

This pilot study was a crossover randomized nonblinded controlled trial conducted at a level III neonatal intensive care unit. Infants' care included 30-minute sessions utilizing either a nonweighted or weighted blanket, with infants serving as their own controls.

RESULTS

A total of 16 patients were enrolled for a total of 67 weighted blanket sessions. To address safety, no adverse events were observed, the weighted blankets were never removed due to infant distress, and infants experienced no significant temperature change. To address feasibility, 94% of approached mothers were receptive to the use of weighted blankets and staff reported no obstacles to using the blanket. Finally, to assess effectiveness, there was a significant decrease in the infant's heart rate and Finnegan score when a weighted blanket was used. There was no significant change in respiratory rate with the use of a weighted blanket.

IMPLICATIONS FOR PRACTICE

Weighted blankets may be safe, feasible, and effective in decreasing NAS symptoms.

IMPLICATIONS FOR RESEARCH

Larger studies are needed to thoroughly study the use of weighted blankets in this population and examine additional outcomes, such as need for pharmacologic intervention, length of hospital stay, and cost of hospital stay.

The efficacy of ball blankets on insomnia in depression in outpatient clinics: study protocol for a randomized crossover multicentre trial

Background

Depression affects approx. 4% of the global population and is often accompanied by insomnia. Medications used to treat insomnia can have side effects such as development of tolerance and addiction. The Protac Ball Blanket™ (PBB) is a non-pharmacological supplement to sedatives and hypnotics, but evidence for the efficacy of PBB is needed before the treatment is implemented. The objective of this trial is to test the efficacy of PBB on insomnia caused by depression in a randomized controlled design.

Methods

This study is a multicentre, randomized crossover trial with planned inclusion of 45 patients. The randomization procedure is permuted-block randomization with varying block sizes. Patients are allocated into either a sequence “AB” or “BA” each lasting 4 weeks (28 nights). Patients randomized to the “AB” sequence receive treatment A (Protac Ball Blanket™) in the first 2 weeks and switch to treatment B (treatment as usual) in the second period, whereas patients who are randomized to the BA sequence receive treatment B in the first period and treatment A in the second period. The participants will serve as their own control in this design. The primary outcome is changes in total sleep time. Secondary outcome measures are changes in sleep onset latency, number of awakenings, wake after sleep onset, and use of sedatives and hypnotics. Furthermore, quality of sleep, insomnia severity status, and self-reported symptoms of depression, anxiety, interpersonal sensitivity, and neurasthenia will be measured. A paired, two-sided t test to compare the means of the differences in the outcomes will be performed.

Discussion

This clinical trial will assess the effect of PBB on depression-related insomnia. The outcomes are of high interest as the PBB is a potential non-pharmacological supplement to medical treatment of patients with insomnia due to depression.

Cumulative incidence and relative risk of sleep problems among children and adolescents with newly diagnosed neurodevelopmental disorders: A nationwide register-based study

We estimated the absolute and relative risk of sleep problems in children and adolescents with newly diagnosed neurodevelopmental disorders. This was a population-based cohort study of individuals born in Denmark in 1993-2014 and followed in nationwide registers in 2011-2016. We estimated the 5-year cumulative incidence of sleep problems in incident cases of attention-deficit/hyperactivity disorder (ADHD; n = 12,844), autism spectrum disorder (ASD; n = 8,073), oppositional defiant disorder/conduct disorder (ODD/CD; n = 2,234) and epilepsy (n = 3,709). Hazard ratios (HRs) for sleep problems were estimated by Cox regression. The 5-year risk of sleep problems was highest in ADHD (29.2%; 95% CI, 28.4-30.1), ASD (24.2%; 95% CI, 23.1-25.3) and ODD/CD (27.1% 95% CI, 25.0%-29.2%) and lowest in epilepsy (11.3%; 95% CI, 10.2%-12.6%). For ADHD and ASD, sleep problems were more common in females than in males. Furthermore, sleep problems were predicted by high parental socioeconomic status and varied with the geographical region of residence, suggesting that different clinical practices exist across Denmark and that sleep problems may be more likely to go undetected in families of lower socioeconomic position. Compared with individuals without these disorders, the likelihood of sleep problems was increased in individuals with ADHD (HR, 33.81; 95% CI, 32.78-34.87), ASD (HR, 16.77; 95% CI, 16.15-17.41), ODD/CD (HR, 14.73; 95% CI, 13.88-15.64) and epilepsy (HR, 6.01; 95% CI, 5.67-6.37). After mutual adjustment for comorbidity, HRs were attenuated, especially in ASD, ODD/CD and epilepsy when adjusted for ADHD, suggesting that the increased risk of sleep problems in individuals with ASD, ODD/CD and epilepsy is driven largely by comorbid ADHD.

DSM-5 Changes in Attention Deficit Hyperactivity Disorder and Autism Spectrum Disorder: Implications for Comorbid Sleep Issues

Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) are the most common neurodevelopmental disorders. Despite significant comorbidity, the previous diagnostic criteria prohibited the simultaneous diagnosis of both disorders. Sleep problems are highly prevalent in both disorders; however, these have been studied independently for ADHD and ASD. In the context of revised criteria in the Diagnostic Statistical Manual of Mental Disorders 5th edition (DSM-5) that allows combined diagnosis of ADHD and ASD, this short review presents an overview of relationship between sleep problems, ADHD and ASD, as well as conceptualizing the shared pathophysiology. The practical considerations for clinical management of sleep problems in combination with ADHD and ASD are also discussed.

Non-pharmacological management of problematic sleeping in children with developmental disabilities

AIM

Sleep is important for underlying neural plasticity, and children with developmental disabilities suffer behavioural, emotional, cognitive, and sensory-motor issues that affect their wake and sleep states. Problematic sleeping can be hypothesized to have adverse effects on both of these areas in children with developmental disabilities. With this review, we aim to provide a benchmark in managing problematic sleeping in children with developmental disabilities.

METHOD

A literature search was conducted and data on the study descriptives, patient characteristics, study design, study-related factors, criteria applied to operationalize sleep and developmental disability, and sleep 'management' were collected. Each management strategy was tabulated and analysed.

RESULTS

We identified 90 studies involving 1460 children with developmental disabilities, of whom 61.6% were male. The highest proportion of studies, almost half, were in children with syndromes (44.4%), followed by studies in children with intellectual disabilities (18.9%). Non-pharmacological sleep management was primarily aimed at improving sleep quality (86.7%), followed by sleep-wake schedules and, to a certain extent, sleep regularity (42.2%). About 56.7% of the studies reported more than one approach. Studies mostly focused on disorders of initiating and maintaining sleep through a diversity of strategies and relied heavily on subjective measures to identify and monitor problematic sleeping. Sleep management approaches were primarily delivered at the level of the individual in the home setting. The number of management approaches per study was unrelated to the number of sleep problems discussed.

INTERPRETATION

Modifying sleep management strategies to meet the specific needs of children with developmental disabilities is encouraged, and studies that look beyond sleep quality or sleep quantity are required. It is also advocated that modifications to sleep hygiene, sleep regularity, and sleep ecology in a population with developmental disabilities are rigorously investigated. Finally, daytime somnolence should not be overlooked when aiming to optimize sleep in children with developmental disabilities across the ages and stages of their lives. There were several limitations in the research findings of problematic sleep in children with developmental disabilities. In general, the sleep problems and the developmental disabilities investigated were multicomponent in nature. It is likely that management approaches impacted those problems on multiple levels or through diverse 'therapeutic' pathways. There is a need for randomized controlled trials and more objective measures that quantify improved sleep or wake states.

Associations of sleep disturbance with ADHD: implications for treatment

Attention-deficit/hyperactivity disorder (ADHD) is commonly associated with disordered or disturbed sleep. The relationships of ADHD with sleep problems, psychiatric comorbidities and medications are complex and multidirectional. Evidence from published studies comparing sleep in individuals with ADHD with typically developing controls is most concordant for associations of ADHD with: hypopnea/apnea and peripheral limb movements in sleep or nocturnal motricity in polysomnographic studies; increased sleep onset latency and shorter sleep time in actigraphic studies; and bedtime resistance, difficulty with morning awakenings, sleep onset difficulties, sleep-disordered breathing, night awakenings and daytime sleepiness in subjective studies. ADHD is also frequently coincident with sleep disorders (obstructive sleep apnea, peripheral limb movement disorder, restless legs syndrome and circadian-rhythm sleep disorders). Psychostimulant medications are associated with disrupted or disturbed sleep, but also ‘paradoxically’ calm some patients with ADHD for sleep by alleviating their symptoms. Long-acting formulations may have insufficient duration of action, leading to symptom rebound at bedtime. Current guidelines recommend assessment of sleep disturbance during evaluation of ADHD, and before initiation of pharmacotherapy, with healthy sleep practices the first-line option for addressing sleep problems. This review aims to provide a comprehensive overview of the relationships between ADHD and sleep, and presents a conceptual model of the modes of interaction: ADHD may cause sleep problems as an intrinsic feature of the disorder; sleep problems may cause or mimic ADHD; ADHD and sleep problems may interact, with reciprocal causation and possible involvement of comorbidity; and ADHD and sleep problems may share a common underlying neurological etiology.

Use of actigraphy for assessment in pediatric sleep research

The use of actigraphs, or ambulatory devices that estimate sleep-wake patterns from activity levels, has become common in pediatric research. Actigraphy provides a more objective measure than parent-report, and has gained popularity due to its ability to measure sleep-wake patterns for extended periods of time in the child's natural environment. The purpose of this review is: 1) to provide comprehensive information on the historic and current uses of actigraphy in pediatric sleep research; 2) to review how actigraphy has been validated among pediatric populations; and 3) offer recommendations for methodological areas that should be included in all studies that utilize actigraphy, including the definition and scoring of variables commonly reported. The poor specificity to detect wake after sleep onset was consistently noted across devices and age groups, thus raising concerns about what is an "acceptable" level of specificity for actigraphy. Other notable findings from this review include the lack of standard scoring rules or variable definitions. Suggestions for the use and reporting of actigraphy in pediatric research are provided.
