“…We have also observed less K‐complexes during stage 2 in school‐aged children with ASD (Lambert et al, ) and low levels of delta EEG activity in adults with ASD (Rochette, Soulières, Berthiaume, & Godbout, ). In the case of sleep spindles, the location of divergent recording sites between ASD and TD groups was in the frontal area for children and in the central area in adults (Lambert et al, ; Limoges et al, ), while delta EEG activity differences between ASD and TD adults occurred in the posterior recording areas (Rochette et al, ). These observations further support the notion that the topographical deviation of EEG activity in ASD constitutes an EEG trait of this neurodevelopmental disorder.…”

“…Dissimilarities in EEG oscillations during NREM sleep between ASD and TD subjects is a common finding in adults and children with ASD, including short durations of SWS and low incidence of sleep spindles during stage 2 (Lambert et al, ; Limoges, Bolduc, Berthiaume, Mottron, & Godbout, ). We have also observed less K‐complexes during stage 2 in school‐aged children with ASD (Lambert et al, ) and low levels of delta EEG activity in adults with ASD (Rochette, Soulières, Berthiaume, & Godbout, ).

“…Accordingly, it has been proposed that amplitude and slope of SW (>75 µV) are markers of synaptic density and strength in the thalamo‐cortical loop (Kurth et al., ). The fact that children with ASD display less SWS, less sleep spindles and less K‐complexes than TD children (Lambert et al, ; Tessier, Lambert, Scherzer, Jemel, & Godbout, ) points toward an impaired integrity of thalamo‐cortical neurons in children with ASD. Whether markers of synaptic density and strength of thalamo‐cortical neurons are modified in children with ASD is, however, still unknown.…”

Summary Autism is a developmental disorder with a neurobiological aetiology. Studies of the autistic brain identified atypical developmental trajectories that may lead to an impaired capacity to modulate electroencephalogram activity during sleep. We assessed the topography and characteristics of non‐rapid eye movement sleep electroencephalogram slow waves in 26 boys aged between 6 and 13 years old: 13 with an autism spectrum disorder and 13 typically developing. None of the participants was medicated, intellectually disabled, reported poor sleep, or suffered from medical co‐morbidities. Results are derived from a second consecutive night of polysomnography in a sleep laboratory. Slow waves (0.3–4.0 Hz; >75 µV) were automatically detected on artefact‐free sections of non‐rapid eye movement sleep along the anteroposterior axis in frontal, central, parietal and occipital derivations. Slow wave density (number per minute), amplitude (µV), slope (µV s−1) and duration (s) were computed for the first four non‐rapid eye movement periods. Slow wave characteristics comparisons between groups, derivations and non‐rapid eye movement periods were assessed with three‐way mixed ANOVAs. Slow wave density, amplitude, slope and duration were higher in anterior compared with most posterior derivations in both groups. Children with autism spectrum disorder showed lower differences in slow waves between recording sites along the anteroposterior axis than typically developing children. These group differences in the topography of slow wave characteristics were stable across the night. We propose that slow waves during non‐rapid eye movement sleep could be an electrophysiological marker of the deviant cortical maturation in autism linked to an atypical functioning of thalamo‐cortical networks.

“…Sleep problems include difficulty falling asleep, inconsistent sleep schedules, insufficient nighttime sleep, as well as daytime sleepiness that impairs daytime functioning (Goldman, Richdale, Clemons, & Malow, 2012). These impairments include increased irritability, greater anxiety, higher sensory sensitivity, and more behavior problems (Katz, Malow, & Reynolds, 2016;Lambert et al, 2016;Malow et al, 2006;Mazurek & Petroski, 2015;Schreck, Mulick, & Smith, 2004;Sikora, Johnson, Clemons, & Katz, 2012). Poorer daytime functioning in turn may be linked to poorer quality social relationships.…”

A B S T R A C TBackground: Individuals with Autism Spectrum Disorder (ASD) experience impairments in social communication, and these deficits often make it difficult to form and maintain friendships with peers. Poor sleep quality and daytime sleepiness are common among adolescents with ASD, and consequences of poor sleep may make social interactions difficult. Connections between sleep quality and social relationships in ASD samples have been understudied; the current study addresses this gap. Method: Participants were community samples of 19 adolescents with ASD and 10 neurotypical (NT) adolescents. Adolescents completed questionnaires about closeness and discord in relationships with a same-gender peer, and they reported on sleep-wake problems, daytime sleepiness, and internalizing problems. Adolescents also wore an actigraph for 7-nights. Results: Pearson correlations revealed significant associations between adolescents' reports of sleep problems and discordant peer relationships; more sleep-wake problems and more daytime sleepiness were associated with more discord with peers in the sample with ASD, but not in the NT sample. The closeness aspect of peer relationships was not significantly associated with sleep quality. Internalizing problems did not mediate between sleep quality and discordant relationships. Conclusions: Adolescents' reports of more sleep problems and daytime sleepiness, but not actigraph indicators of sleep quality, were directly associated with discordant peer relationships. Adolescents who are already challenged in social interactions due to ASD may be especially vulnerable to intense negativity in peer relationships when they also experience poorer nighttime sleep and more daytime sleepiness. NT adolescents may be better able to regulate social interactions despite poor sleep and feeling tired.
