The relationship between sleep difficulties and externalizing and internalizing problems in children and adolescents with mental illness.

Sleep difficulties are presumably a transdiagnostic factor in the complex aetiology of psychiatric disorders in youth. This study assessed the prevalence of sleep difficulties in children and adolescents seeking specialized psychiatric care, examined the relationships of internalizing and externalizing problems, and considered the moderating role of sex and age on these relationships. Parent-reported data on difficulties initiating sleep, difficulties maintaining sleep, early morning awakenings and daytime fatigue from a large sample of children and adolescents referred for specialized psychiatric care (n = 4638; < 18 years) were used to estimate prevalence rates.

The short and long-term effects of a lifestyle intervention in children with mental illnesses: a randomized controlled trial (Movementss study).

Background: A lifestyle including poor diet, physical inactivity, excessive gaming and inadequate sleep hygiene is frequently seen among Dutch children. These lifestyle behaviors can cause long-term health problems later in life. Unhealthy lifestyle and poor physical health are even more prevalent among children with mental illness (MI) such as autism, attention-deficit/hyperactivity disorder, depression, and anxiety.

What is in a name? Definitions of insomnia in people with intellectual disabilities.

Background: The reported prevalence of insomnia symptoms in people with intellectual disabilities varies greatly, possibly due to the lack of a common definition. This article provides an overview of the different definitions used and formulates key points for a general definition.

Methods: A literature search was performed.

Recognizing the Symptom Spectrum of Narcolepsy to Improve Timely Diagnosis: A Narrative Review.

Narcolepsy is a chronic sleep disorder with a strong negative impact on quality of life, especially when untreated. Diagnostic delay is a persistent problem, with obvious detrimental effects on patients. A diagnosis of narcolepsy may be delayed because of its broad symptom presentation which is much more encompassing than the classical "tetrad" of sleepiness, cataplexy, hallucinations, and sleep paralysis.

It is All in the Wrist: Wearable Sleep Staging in a Clinical Population versus Reference Polysomnography.

Purpose: There is great interest in unobtrusive long-term sleep measurements using wearable devices based on reflective photoplethysmography (PPG). Unfortunately, consumer devices are not validated in patient populations and therefore not suitable for clinical use. Several sleep staging algorithms have been developed and validated based on ECG-signals.

The CHD8/CHD7/Kismet family links blood-brain barrier glia and serotonin to ASD-associated sleep defects.

Sleep disturbances in autism and neurodevelopmental disorders are common and adversely affect patient's quality of life, yet the underlying mechanisms are understudied. We found that individuals with mutations in , among the highest-confidence autism risk genes, or suffer from disturbed sleep maintenance. These defects are recapitulated in mutants affecting , the sole ortholog.

Sleep problems in children with cerebral palsy and their parents.

Aim: To describe: (1) the frequency and types of sleep problems, (2) parent-rated satisfaction with their child's and their own sleep, and (3) child factors related to the occurrence of sleep problems in children with cerebral palsy (CP) and their parents. The secondary objective was to compare the sleep outcomes of children with CP with those from typically developing children and their parents.

Method: The Sleep section of the 24-hour activity checklist was used to assess the sleep of children with CP and their parents and the sleep of typically developing children and their parents.

The value of cardiorespiratory parameters for sleep state classification in preterm infants: A systematic review.

Cardiorespiratory activity is highly associated with infants' sleep duration and quality. We performed a systematic literature search of PubMed and EMBASE databases to investigate if and how cardiorespiratory parameters can be used for sleep state classification in preterm infants and in what way maturation influences this relation. All retrieved citations were screened against predetermined inclusion and exclusion criteria.

The relationship between preterm birth and sleep in children at school age: A systematic review.

Premature birth (before 37 weeks of gestation) has been linked to a variety of adverse neurological outcomes. Sleep problems are associated with decreased neurocognitive functioning, which is especially common in children born preterm. The exact relationship between prematurity and sleep at school age is unknown.

Two sides of a coin: differential response to COVID-19 distancing measures in children with narcolepsy.

Narcolepsy is a chronic neurological sleep disorder, debuting before age 15 years in one-third of patients. Narcolepsy has a negative influence on quality of life, with daily functioning being affected by concomitant cognitive, behavioral, and social problems. In December 2019, a new coronavirus emerged worldwide, causing the severe respiratory disease COVID-19.

24-hour activity for children with cerebral palsy: a clinical practice guide.

The association between physical activity and health has been clearly established, and the promotion of physical activity should be viewed as a cost-effective approach that is universally prescribed as a first-line treatment for nearly every chronic disease. Health care providers involved in the care for individuals with cerebral palsy (CP) are encouraged to take an active role in promoting their health and well-being. Balancing activity behaviours across the whole day, with improved physical activity, reduced sedentary time, and healthy sleep behaviours, can set up infants, preschool-, and school-aged children with CP for a healthy trajectory across their lifetime.

Sleep health practices and sleep knowledge among healthcare professionals in Dutch paediatric rehabilitation.

Background: Sleep disorders are highly prevalent in children with neurodisabilities, yet they seem under-recognized in paediatric rehabilitation settings. The aim of this study was to assess among two groups of healthcare professionals (HCPs) working in paediatric rehabilitation: (1) sleep health practices and (2) knowledge about sleep physiology, sleep disorders and sleep hygiene.

Methods: We performed a cross-sectional sleep survey among medical and non-medical HCPs and the general population.

Parental perspectives on care for sleep in children with cerebral palsy: a wake-up call.

Purpose: Sleep problems are common in children with cerebral palsy (CP) and have a large impact on child health and family functioning. This qualitative study aimed to explore parental perspectives regarding the care for sleep of their young child (age 1-8 years) with CP.

Materials And Methods: Individual, semi-structured interviews were conducted with eighteen parents of a child with CP (GMFCS levels I-V).

Effect of treatment on cognitive and attention problems in children with narcolepsy type 1.

Study Objectives: To ascertain the presence of cognitive and attention problems in treatment naïve children with narcolepsy type 1 (NT1) and to explore whether children recently diagnosed with NT1 improve with respect to cognition and attention problems 1 year after regular treatment for NT1.

Methods: A total of 15 treatment naïve children (7-15 years) with recently diagnosed NT1 were recruited from three sleep medicine centers in the Netherlands. The control group consisted of 15 healthy children, being frequency matched on age and gender.

Psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance and Sleep-Related Impairment item banks in adolescents.

Sleep problems have a high prevalence and negative daytime consequences in adolescents. Current sleep measures for this age group have limitations. The Patient-Reported Outcomes Measurement Information System (PROMIS ) developed sleep item banks for adults.

A Mobile App for Longterm Monitoring of Narcolepsy Symptoms: Design, Development, and Evaluation.

Background: Narcolepsy is a chronic sleep disorder with a broad variety of symptoms. Although narcolepsy is primarily characterized by excessive daytime sleepiness and cataplexy (loss of muscle control triggered by emotions), patients may suffer from hypnagogic hallucinations, sleep paralysis, and fragmented night sleep. However, the spectrum of narcolepsy also includes symptoms not related to sleep, such as cognitive or psychiatric problems.

Protocol of the SOMNIA project: an observational study to create a neurophysiological database for advanced clinical sleep monitoring.

Introduction: Polysomnography (PSG) is the primary tool for sleep monitoring and the diagnosis of sleep disorders. Recent advances in signal analysis make it possible to reveal more information from this rich data source. Furthermore, many innovative sleep monitoring techniques are being developed that are less obtrusive, easier to use over long time periods and in the home situation.

The impact of delayed sleep phase disorder on adolescents and their family.

Introduction: We investigated the impact of delayed sleep phase disorder (DSPD) on the daily lives of adolescents and their families.

Method: In this qualitative study, six adolescents with DSPD, and six parents were given in-depth interviews. Using thematic analysis, we merged open codes into themes that reflected the impact of the disorder.

Impaired social functioning in children with narcolepsy.

Study Objectives: To explore impairments in social functioning in children with narcolepsy compared to healthy children.

Methods: Parents of 53 pediatric patients with narcolepsy type 1 and 64 matched healthy children completed the Social Responsiveness Scale (SRS) and the Child Behavior Checklist 6-18 (CBCL 6-18).

Results: Patients scored significantly higher on the total score of the SRS (median 56, interquartile range [IQR] 23.

Ultrasound of peripheral nerves in neuralgic amyotrophy.

Introduction: Neuralgic amyotrophy (NA) can often be difficult to diagnose. Nerve ultrasound (US) is potentially useful, but it is operator-dependent, especially for small nerves.

Methods: Fifty-one consecutive patients with NA (mean duration 16 months) and 50 control subjects underwent US of the brachial plexus and major nerves of the upper extremity at predefined sites.
