Objective: The hypersensitivity of children with autism to sound is a relatively unexplained behavior. The goal of the current study was to investigate the DPOAE characteristics of children with autism compared to a control group.
Design: DPOAEs with and without contralateral stimuli were measured in two groups in three different conditions.
Study Sample: The study employed 14 children with autism and a control group with 28 age-matched participants.
Results: In the without-contralateral stimulus condition, the overall S/N of DPOAEs was greater for the control group compared to the autism group (p < 0.0005). For both groups, the DPOAE S/N increased as a function of frequency in both ears. In the with contralateral stimulus condition, group and ear effects were noticed, however, no age, frequency, or contralateral stimulus type (BBN vs. 1000 Hz) effect could be detected.
Conclusions: Presence of reduced DPOAEs in the autism group does not support the hypothesis that sound hypersensitivity in children with autism may be related to overactive outer hair cells function; rather it may be due to early cochlear dysfunction. Also, sound hypersensitivity in the autism group may be due to abnormality of the efferent auditory pathway as shown by lack of sufficient contralateral suppression.

Neurodivergent youth often experience anxiety and depressive symptoms that may hamper adaptive functioning and well-being. There is little knowledge of how anxiety and depression are related in neurodivergent youth. Therefore, we aimed to examine whether the relationship between anxiety and depressive symptoms is uni- or bidirectional in neurodiverse youth.

Unlabelled: Spondyloenchondrodysplasia (SPENCD) is a rare genetic disorder characterized with skeletal dysplasia, immune dysregulation, and neurological impairment. Patients diagnosed with SPENCD at a single pediatric hematology center were included in the study. The patients' clinical characteristics, symptoms at presentation, imaging and laboratory results, and genetic analysis results were collected retrospectively from their files.

Emerging evidence suggests aberrant functional connectivity (FC) of brain networks in children, adolescents, and adults with autism spectrum disorder (ASD). However, little is known about alterations of dynamic FC in toddlers with ASD. The aim of this study was to investigate the characteristics of brain network dynamics in ASD toddlers.

Autism spectrum disorder (ASD) is an early-onset neurodevelopmental disorder characterised by highly heterogeneous language abilities. These variations necessitate sensitive and comprehensive assessments, with narrative analysis being an effective method. This study aimed to examine the micro- and macrostructural aspects of narratives of Mandarin-speaking children with ASD.
