Sensory seeking behavior occurs as compensation for SOR, and individuals may seek sensory input in one sensory domain to compensate for SOR. Tactile seeking behavior is sufficient to decrease social anxiety in communicating with unfamiliar people. We assessed the effectiveness of hugging a huggable device before a conversation for reducing the psychological stress associated with speaking to an unfamiliar person or robot. Our analysis showed a significant effect, with Hugvie contributing to decreased stress for both interlocutors. Thus, this study demonstrated the efficacy of hugging it before conversation, which emphasizes the importance of tactile seeking for individuals with ASD.

However, much remains unknown because of the heterogeneity of disorders and the potential confounders such as dietary patterns and control group variations. Methods Children aged 6-12?years who had been clinically diagnosed with ASD and/or ADHD, their unaffected neurotypical siblings, and non-related neurotypical volunteers were recruited cross-sectionally. The ASD diagnosis was confirmed using the Autism Diagnostic Observation Schedule-2 (ADOS-2) in all patients, including those with ADHD. Standardized DNA extraction and sequencing methods were used to compare gut microbial alpha-diversity among the groups. Dietary diversity was calculated from a standardized dietary questionnaire form. We compared the difference in gut microbiome between patients with ASD and/or ADHD with neurotypical siblings and non-related neurotypical controls. Results Ninety-eight subjects were included in the study (18 with ASD, 19 with ADHD, 20 with both ASD and ADHD, 13 neurotypical siblings, and 28 non-related neurotypical controls). The alpha-diversity indices, such as Chao 1 and Shannon index, showed a significant difference between the groups in a Linear mixed-effect model (F(4, 93) = 4.539, p = .02), (F(4, 93) = 3.185, p = .017), respectively. In a post-hoc pairwise comparison, patients with ASD had lower alpha-diversity compared with non-related controls after Bonferroni correction. Dietary diversity shown in Shannon index did not differ among the groups (F(4, 84) = 1.494, p = .211). Conclusions Our study indicates disorder-specific microbiome differences in patients with ASD. In future research on gut microbiota in neurodevelopmental disorders, it is necessary to consider the impact of ASD and ADHD co-occurrence, and strictly control for background information such as diet, to elucidate the gut-microbiota interaction in ASD and ADHD for exploring the potential of therapeutic interventions.

Sex differences in cognitive and symptom profiles in children with high functioning autism spectrum disorders / Hirokazu KUMAZAKI in Research in Autism Spectrum Disorders, 13-14 (May 2015)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 13-14 (May 2015) . - p.1-7 Titre : Sex differences in cognitive and symptom profiles in children with high functioning autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Hirokazu KUMAZAKI, Auteur ; Taro MURAMATSU, Auteur ; Hirotaka KOSAKA, Auteur ; Takashi X. FUJISAWA, Auteur ; Kazuhiko IWATA, Auteur ; Akemi TOMODA, Auteur ; Kenji TSUCHIYA, Auteur ; Masaru MIMURA, Auteur Article en page(s) : p.1-7 Langues : Anglais (eng) Mots-clés : High functioning autism spectrum disorders  Sex differences  Narrow age range  Before adolescence  CARS-TV  Taste, Smell, Touch Response and Use Index. décimale : PER Périodiques Résumé : Abstract Although a small number of studies have investigated sex differences in the associated features of high-functioning autism spectrum disorders (HFASDs), they have failed to provide consistent findings. We sought to examine sex differences in 5–9-year-old females and males with HFASDs within a narrow range of ages before adolescence in order to identify the noticeable autistic profile of females compared to males. Using the Japanese version of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and the Childhood Autism Rating Scale-Tokyo Version (CARS-TV), 20 females with HFASDs were compared with 26 males with HFASDs. Although females and males with HFASDs share similar cognitive profiles in WISC-III, females demonstrated a different symptom profile from males in CARS-TV. Although the female subjects scored significantly lower than the male subjects on “Body Use,” “Object Use,” and “Activity Level,” female subjects scored significantly higher than males on “Taste, Smell, and Touch Response and Use” in the CARS-TV. This finding can be useful for the early identification of females with HFASDs who have typically been underdiagnosed. Future research should focus on elucidating the possible behavioral, neurological, and genetic links to these sex differences.
