Altered Cortical Thickness and Tract Integrity of the Mirror Neuron System and Associated Social Communication in Autism Spectrum Disorder / Hsiang-Yun CHIEN in Autism Research, 8-6 (December 2015)  

Public ISBD [article]  inAutism Research > 8-6 (December 2015) . - p.694-708 Titre : Altered Cortical Thickness and Tract Integrity of the Mirror Neuron System and Associated Social Communication in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Hsiang-Yun CHIEN, Auteur ; Susan Shur-Fen GAU, Auteur ; Yung-Chin HSU, Auteur ; Yu-Jen CHEN, Auteur ; Yu-Chun LO, Auteur ; Yao-Chia SHIH, Auteur ; Wen-Yih Isaac TSENG, Auteur Article en page(s) : p.694-708 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  mirror neuron system  diffusion spectrum imaging  cortical thickness  white matter integrity  tractography  social communication Index. décimale : PER Périodiques Résumé : Previous studies using neural activity recording and neuroimaging techniques have reported functional deficits in the mirror neuron system (MNS) for individuals with autism spectrum disorder (ASD). However, a few studies focusing on gray and white matter structures of the MNS have yielded inconsistent results. The current study recruited adolescents and young adults with ASD (aged 15–26 years) and age-matched typically developing (TD) controls (aged 14–25 years). The cortical thickness (CT) and microstructural integrity of the tracts connecting the regions forming the classical MNS were investigated. High-resolution T1-weighted imaging and diffusion spectrum imaging were performed to quantify the CT and tract integrity, respectively. The structural covariance of the CT of the MNS regions revealed a weaker coordination of the MNS network in ASD. A strong correlation was found between the integrity of the right frontoparietal tracts and the social communication subscores measured by the Chinese version of the Social Communication Questionnaire. The results showed that there were no significant mean differences in the CTs and tract integrity between the ASD and TD groups, but revealed a moderate or even reverse age effect on the frontal MNS structures in ASD. In conclusion, aberrant structural coordination may be an underlying factor affecting the function of the MNS in ASD patients. The association between the right frontoparietal tracts and social communication performance implies a neural correlate of communication processing in the autistic brain. This study provides evidence of abnormal MNS structures and their influence on social communication in individuals with ASD.

Altered Structure–Function Relations of Semantic Processing in Youths with High-Functioning Autism: A Combined Diffusion and Functional MRI Study / Yu-Chun LO in Autism Research, 6-6 (December 2013)  

Public ISBD [article]  inAutism Research > 6-6 (December 2013) . - p.561-570 Titre : Altered Structure–Function Relations of Semantic Processing in Youths with High-Functioning Autism: A Combined Diffusion and Functional MRI Study Type de document : Texte imprimé et/ou numérique Auteurs : Yu-Chun LO, Auteur ; Tai-Li CHOU, Auteur ; Li-Ying FAN, Auteur ; Susan Shur-Fen GAU, Auteur ; Yen-Nan CHIU, Auteur ; Wen-Yih Isaac TSENG, Auteur Année de publication : 2013 Article en page(s) : p.561-570 Langues : Anglais (eng) Mots-clés : autism  dual stream model  diffusion spectrum imaging  functional MRI  tractography Index. décimale : PER Périodiques Résumé : Deficits in language and communication are among the core symptoms of autism, a common neurodevelopmental disorder with long-term impairment. Despite the striking nature of the autistic language impairment, knowledge about its corresponding alterations in the brain is still evolving. We hypothesized that the dual stream language network is altered in autism, and that this alteration could be revealed by changes in the relationships between microstructural integrity and functional activation. The study recruited 20 right-handed male youths with autism and 20 carefully matched individually, typically developing (TD) youths. Microstructural integrity of the left dorsal and left ventral pathways responsible for language processing and the functional activation of the connected brain regions were investigated by using diffusion spectrum imaging and functional magnetic resonance imaging of a semantic task, respectively. Youths with autism had significantly poorer language function, and lower functional activation in left dorsal and left ventral regions of the language network, compared with TD youths. The TD group showed a significant correlation of the functional activation of the left dorsal region with microstructural integrity of the left ventral pathway, whereas the autism group showed a significant correlation of the functional activation of the left ventral region with microstructural integrity of the left dorsal pathway, and moreover verbal comprehension index was correlated with microstructural integrity of the left ventral pathway. These altered structure–function relationships in autism suggest possible involvement of the dual pathways in supporting deficient semantic processing.

Autistic Symptoms, Irritability, and Executive Dysfunctions: Symptom Dynamics from Multi-Network Models / Susan Shur-Fen GAU ; Wan-Ling TSENG in Journal of Autism and Developmental Disorders, 54-8 (August 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-8 (August 2024) . - p.3078-3093 Titre : Autistic Symptoms, Irritability, and Executive Dysfunctions: Symptom Dynamics from Multi-Network Models Type de document : Texte imprimé et/ou numérique Auteurs : Susan Shur-Fen GAU, Auteur ; Wan-Ling TSENG, Auteur Article en page(s) : p.3078-3093 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Socio-cognitive difficulties in individuals with autism spectrum disorder (ASD) are heterogenuous and often co-occur with irritability symptoms, such as angry/grouchy mood and temper outbursts. However, the specific relations between individual symptoms are not well-represented in conventional methods analyzing aggregated autistic symptoms and ASD diagnosis. Moreover, the cognitive-behavioral mechanisms linking ASD to irritability are largely unknown. This study investigated the dynamics between autistic (Social Responsiveness Scale) and irritability (Affective Reactivity Index) symptoms and executive functions (Cambridge Neuropsychological Test Automated Battery) in a sample of children and adolescents with ASD, their unaffected siblings, and neurotypical peers (N = 345, aged 6-18 years, 78.6% male). Three complementary networks across the entire sample were computed: (1) Gaussian graphical network estimating the conditional correlations between symptom nodes; (2) Relative importance network computing relative influence between symptoms; (3) Bayesian directed acyclic graph estimating predictive directionality between symptoms. Networks revealed numerous partial correlations within autistic (rs = .07-.56) and irritability (rs = .01-.45) symptoms and executive functions (rs = ?.83 to .67) but weak connections between clusters. This segregated pattern converged in all directed and supplementary networks. Plausible predictive paths were found between social communication difficulties to autism mannerisms and between "angry frequently" to "lose temper easily." Autistic and irritability symptoms are two relatively independent families of symptoms. It is unlikely that executive dysfunctions explain elevated irritability in ASD. Findings underscore the need for researching other mood and cognitive-behavioral bridge symptoms, which may inform individualized treatments for co-occurring irritability in ASD.

Autistic Traits in Couple Dyads as a Predictor of Anxiety Spectrum Symptoms / Winnie Yu-Pow LAU in Journal of Autism and Developmental Disorders, 44-11 (November 2014)

Parental autistic tendency as measured by Autism Spectrum Quotient (AQ) was associated with anxiety symptoms across all domains. Large effect sizes were found in social phobia and post traumatic stress disorders for both parents, and in general anxiety disorder and agoraphobia for mothers. These associations were irrespective of child’s autistic tendency, spouse’s AQ scores and the couples’ compatibility in their autistic tendency. Perceived family support and parental education moderated the link but not child’s autistic severity. Research and clinical implications regarding psychiatric vulnerability of parents of children with ASD were drawn and discussed.
