However, the relationship between AOW and variations in ASD symptoms across different neurodevelopmental disorders is largely unknown. This study investigated AOW and its association with autism symptom severity in a large sample of children (N = 490, 23% females) clinically evaluated for suspected ASD, differentiated into ASD (n = 376) and non-ASD (n = 114) diagnoses. Children with ASD achieved independent walking significantly later than children with non-ASD diagnoses. AOW was significantly associated with ASD symptom severity, and females had a non-significant later AOW. The current findings suggest that in cases with delayed AOW, ASD should be considered as an actual differential diagnosis, perhaps particularly in girls.

Atypical event-related potentials revealed during the passive parts of a Go-NoGo task in autism spectrum disorder: a case-control study / A.L. HOYLAND in Molecular Autism, 10 (2019)

Index. décimale : PER Périodiques Résumé : Background: The core features of autism spectrum disorder (ASD) are easily recognizable in non-structured clinical and real-life situations. The features are often difficult to capture in structured laboratory settings, and the results from tests do not necessarily reflect symptom severity. We investigated neurophysiological processing in the passive parts of a cued Go-NoGo task, using the active parts of the test as a comparator. Methods: Forty-nine adolescents diagnosed with ASD and 49 typically developing (TD) adolescents (age 12-21 years) were included. Daily life executive function was assessed with the Behavior Rating Inventory of Executive Function (BRIEF). We applied a visual cued Go-NoGo task and recorded event-related potentials (ERPs). We investigated occipital N1, a component related to early perception of visual stimuli, and P3a, a fronto-central component related to switching of attention, in the passive and active parts of the test. Results: During the passive parts, the ASD group had statistically significantly longer N1 latency (p < 0.001, Cohens d = 0.75) and enhanced amplitude of P3a (p = 0.002, Cohens d = 0.64) compared to the TD, while no significant differences were observed in the active parts. Both components correlated significantly with the Behavioral Regulation Index of the BRIEF (partial correlation r = 0.35, p = 0.003). Conclusion: Delayed N1 response, indicating altered visual perception, and enhanced P3a response, indicating increased neural activation related to attention allocation, were found during the passive parts of a Go-NoGo task in ASD participants. These abnormal ERP signals in the non-structured settings were associated with everyday executive function, suggesting that neurophysiolocal measures related to atypical control of alertness and "hyper-awareness" underlie daily life dysfunction in ASD. Assessments during passive settings have a potential to reveal core neurobiological substrates of ASD.

Promotive factors associated with reduced anxiety and depression across three years in a prospective clinical cohort of adolescents: Examining compensatory and protective models of resilience / Jan L.

We prospectively examined the role of the promotive factors structured style, personal and social competencies, family functioning, and social resources in homotypic and heterotypic continuity and discontinuity of anxiety and depression across three years in a clinical sample. Participants were adolescents with anxiety or depressive disorders aged 13-18 years at T1 (N = 717, 44% initial participation rate) and aged 16-21 years at T2 (N = 549, 80% follow-up participation rate). At T1, diagnoses were collected from medical records and participants responded to questionnaires. At T2, semi-structured diagnostic interviews were conducted. Higher levels of all promotive factors were associated with reduced probability of anxiety or depression three years later. The promotive factors were not associated with homotypic continuity of anxiety, whereas personal competence beliefs, social competence, and, less strongly, family functioning were associated with reduced homotypic continuity of depression and heterotypic continuity from depression to anxiety. Analyses with interaction terms did not indicate moderation by the promotive factors. Our findings suggest that bolstering promotive factors may be vital for increasing treatment success and preventing recurrence of anxiety and depression in the transition toward adulthood.

Structural and Pragmatic Language Impairments in Children Evaluated for Autism Spectrum Disorder (ASD) / Terje NÆRLAND ; Bernhard WEIDLE ; Stian LYDERSEN ; Ole A. ANDREASSEN ; Anne Mari SUND in Journal of Autism and Developmental Disorders, 53-2 (February 2023)

The relationship between structural language skills and pragmatic competence in children with autistic symptoms, however, is largely unknown. We investigated this relationship based on the Children's Communication Checklist-2 and early language delay among children (N = 177, 19% females) clinically evaluated for ASD, differentiated into ASD (n = 148) and non-ASD (n = 29). Structural language deficits were common and associated with reduced pragmatic competence in both groups. Pragmatic language impairments were most profound in children with ASD. Early language delay and structural language deficits were less common in females. Our findings suggest that assessment of structural language skills should be included in the evaluation of children with suspected ASD.
