To assess the features of sleep in preschoolers with ADHD by means of questionnaire and actigraphy

Background: Preliminary evaluations of behavioral interventions, referred to as pilot studies, predate the conduct of many large-scale efficacy/effectiveness trial. The ability of a pilot study to inform an efficacy/effectiveness trial relies on careful considerations in the design, delivery, and interpretation of the pilot results to avoid exaggerated early discoveries that may lead to subsequent failed efficacy/effectiveness trials. “Risk of generalizability biases (RGB)” in pilot studies may reduce the probability of replicating results in a larger efficacy/effectiveness trial.

Objective: The objective of this study was to assess the links between temperament and sleep in a group of preschoolers with ADHD. Method: Twenty-five ADHD (M = 5.37 years, SD = 1.09) and 22 typically developing (TD; M = 5.10, SD = 1.18) preschoolers participated in the study. Sleep was assessed with the Sleep Disturbance Scale and wrist actigraphy. The Preschool Temperament and Character Inventory (PsTCI) was used to evaluate the child temperament.

Executive functions (EFs) in children with insomnia have not been sufficiently assessed in the literature. This study aimed to describe sleep patterns and habits and EF abilities in preschool children with insomnia, compared to healthy control patients, and to evaluate the relationships between sleep patterns and EFs.

In “Establishing normal values for pediatric nighttime sleep measured by actigraphy: a systematic review and meta-analysis,”
Galland et al. compiled evidence on sleep norms from 87 articles which used actigraphy in youth aged 0 to 18 [1]. The authors suggest
that the resulting average actigraphic sleep duration could serve as normative data [1]. Although this effort has enormous
value given the dearth of data on sleep duration in children and adolescents and the authors acknowledge that their findings are

Objective: Changes of sleep architecture have been reported in children with Spinal Muscular Atrophy type 2 (SMA2), mainly represented by a decrease of arousability. No studies have evaluated the effect of long-term ventilation on sleep parameters in these children. The aim of this study was to evaluate the effects of long-term non-invasive positive pressure ventilation (LTNPPV) on sleep architecture and to assess the residual differences from normal controls.

This retrospective study aims at helping physicians select babies considered at risk for fatal events during sleep. It does so by describing the clinical features and outcome of worrying infants’ behaviour during sleep, with the activation of an emergency medical service and/or emergency department, subsequently referred to the Centre for Paediatric Sleep Medicine and sudden infant death syndrome, Regina Margherita Children’s Hospital, Turin, Italy.

COVID-19 has critically impacted the world. Recent works have found substantial changes in sleep and mental health during the COVID-19 pandemic. Dreams could give us crucial information about people's well-being, so here we have directly investigated the consequences of lockdown on the oneiric activity in a large Italian sample: 5,988 adults completed a web-survey during lockdown.

Purpose: In adolescence, physiological (circadian and homeostatic regulation of sleep) and social habits contribute to delayed sleep onset, while social obligations impose early sleep offset. The effects of delayed school start time on the subjective/objective measures of sleep– wake patterns and academic achievement have not been established.
