A scalable cognitive behavioural therapy intervention for perinatal insomnia: a protocol for a hybrid effectiveness-implementation type 1 randomised controlled trial Open
Background Insomnia symptoms during the perinatal period are prevalent and may contribute to negative mental health and birthing outcomes. Cognitive Behavioural Therapy for Insomnia (CBT-I) is a non-pharmacological therapy efficacious in t…

Sleep Apnea Specific Hypoxic Burden in Children With Down Syndrome and Typically Developing Children Open
Hypoxic burden (HB) is a measure incorporating frequency, depth and duration of respiratory event‐related desaturations. While HB is associated with cardiovascular disease in adults with obstructive sleep apnea (OSA), it has not been asses…

Distinguishing between children referred for assessment of excessive daytime sleepiness using polysomnographic measures Open
Our study suggests that specific sleep architecture patterns could potentially serve as diagnostic biomarkers for distinguishing paediatric narcolepsy from those with IH and those with a non-diagnostic MSLT.

P102 Can EEG spectral analysis distinguish children with narcolepsy from those with idiopathic hypersomnolence and subjective sleepiness? Open
Background EEG spectral analysis provides a measurement of sleep micro-architecture and is a more sensitive measure of sleep disruption than conventional sleep macro-architecture. We aimed to examine the use of this technique in distinguis…

P123 Identifying differences in sleep spindle activity in children with excessive daytime sleepiness Open
Background Sleep spindles have been hypothesised to protect the sleeping brain from external stimuli and thus promote sleep. We aimed to identify differences in sleep spindle activity between children with narcolepsy, idiopathic hypersomno…

Autonomic cardiovascular control is unaffected in children referred for assessment of excessive daytime sleepiness Open
Summary There is conflicting evidence for impaired autonomic control of heart rate (HR) in adults with narcolepsy and idiopathic hypersomnolence (IH). Despite these chronic hypersomnia conditions primarily being diagnosed around the age of…

The surge in heart rate and blood pressure at respiratory event termination is dampened in children with down syndrome Open
These results suggest children with DS have dampened HR and BP responses to respiratory events compared with TD children. Whether this is symptomatic of autonomic dysfunction or a protective factor for the cardiovascular system in children…

Effect of sleep disordered breathing severity in children with Down syndrome on parental wellbeing and social support Open
The degree of parent-reported sleep disturbance in children with DS was linked to suboptimal perceived parental social support and poor psychological wellbeing. Our results emphasise the need for enhanced awareness of the detrimental effec…

Improvement in quality of life with continuous positive airway pressure outweighs the treatment burden in children with obstructive sleep apnea Open
Introduction Continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnea (OSA) may pose a significant burden on families. We assessed the impact of CPAP for children on quality of life (QOL) and caregiver treatment …

Sleepy Kids: are the current diagnostic criteria for multiple sleep latency tests enough? Open
Excessive daytime sleepiness (EDS) is common in childhood and is currently quantified using adult criteria on a multiple sleep latency test (MSLT). This study aimed to describe paediatric MSLT results, particularly focussing on a previousl…

P006 The Impact of Growth Hormone Treatment on Cardiovascular Control in Children with Prader-Willi syndrome Open
Background Many children with Prader-Willi syndrome (PWS) are treated with growth hormone (GH), which may increase the risk of obstructive sleep apnoea. Children with PWS also have impaired cardiac autonomic control due to reduced parasymp…
