TL;DR: The preliminary findings support evidence implicating disturbances in the thalamo-frontal connections in autism and highlight the role of hypoconnectivity between the frontal cortex and thalamus in ASD.
Abstract: Background : Autism has been hypothesized to reflect neuronal disconnection. Several recent reports implicate the key thalamic relay nuclei and cortico-thalamic connectivity in the pathophysiology of autism. Accordingly, we aimed to focus on evaluating the integrity of the thalamic radiation and sought to replicate prior white matter findings in Korean boys with high-functioning autism spectrum disorders (ASD) using Diffusion Tensor Imaging (DTI). Methods : We compared fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) in 17 boys with ASD and 17 typically developing controls in the anterior thalamic radiation (ATR), superior thalamic radiation (STR), posterior thalamic radiation (PTR), corpus callosum (CC), uncinate fasciculus (UF) and inferior longitudinal fasciculus (ILF). Results : The two groups were group-matched on age, IQ, handedness and head circumference. In whole-brain voxel-wise analyses, FA was significantly reduced and MD was significantly increased in the right ATR, CC, and left UF in subjects with ASD (p Conclusions : Our preliminary findings support evidence implicating disturbances in the thalamo-frontal connections in autism. These findings highlight the role of hypoconnectivity between the frontal cortex and thalamus in ASD.

TL;DR: In this paper, abnormal findings of social brain network in Korean children with autism spectrum disorder (ASD) compared with typically developing children (TDC) were investigated, which indicated that children with ASD have different processing of social and emotional experience at the neural level.
Abstract: ObjectiveaaThe aim of this study is to investigate abnormal findings of social brain network in Korean children with autism spectrum disorder (ASD) compared with typically developing children (TDC). MethodsaaFunctional magnetic resonance imaging (fMRI) was performed to examine brain activations during the processing of emotional faces (happy, fearful, and neutral) in 17 children with ASD, 24 TDC. ResultsaaWhen emotional face stimuli were given to children with ASD, various areas of the social brain relevant to social cognition showed reduced activation. Specifically, ASD children exhibited less activation in the right amygdala (AMY), right superior temporal sulcus (STS) and right inferior frontal gyrus (IFG) than TDC group when fearful faces were shown. Activation of left insular cortex and right IFG in response to happy faces was less in the ASD group. Similar findings were also found in left superior insular gyrus and right insula in case of neutral stimulation. ConclusionaaThese findings suggest that children with ASD have different processing of social and emotional experience at the neural level. In other words, the deficit of social cognition in ASD could be explained by the deterioration of the capacity for visual analysis of emotional faces, the subsequent inner imitation through mirror neuron system (MNS), and the ability to transmit it to the limbic system and to process the transmitted emotion.

TL;DR: Novel findings in the different neural mechanisms of social reward learning in children with ASD are presented and a possible useful biomarker of high-functioning ASDs is presented.
Abstract: Purpose We aimed to determine whether Autism Spectrum Disorder (ASD) would show neural abnormality of the social reward system using functional MRI (fMRI). Materials and methods 27 ASDs and 12 typically developing controls (TDCs) participated in this study. The social reward task was developed, and all participants performed the task during fMRI scanning. Results ASDs and TDCs with a social reward learning effect were selected on the basis of behavior data. We found significant differences in brain activation between the ASDs and TDCs showing a social reward learning effect. Compared with the TDCs, the ASDs showed reduced activity in the right dorsolateral prefrontal cortex, right orbitofrontal cortex, right parietal lobe, and occipital lobe; however, they showed increased activity in the right parahippocampal gyrus and superior temporal gyrus. Conclusion These findings suggest that there might be neural abnormality of the social reward learning system of ASDs. Although this study has several potential limitations, it presents novel findings in the different neural mechanisms of social reward learning in children with ASD and a possible useful biomarker of high-functioning ASDs.

TL;DR: In this paper, the effects of therapists' self-efficacy and stress coping strategies on burnout were investigated, which indicated that art therapists had low-level burnout and moderate- or high-level selfefficacy.
Abstract: This study investigated the effects of therapists’ self-efficacy and stress coping strategies on burnout. 140 art therapists with at least one year of professional experience completed a questionnaire designed to examine participants’ professional characteristics along with measures of burnout, self-efficacy and stress coping strategies. Data were analyzed using frequency and percentage, mean and standard deviation, correlation analysis and multiple regression analysis. The findings indicated that art therapists had low-level burnout and moderate- or high-level self-efficacy. Seeking social support coping was most commonly used stress coping strategy. There were significant correlations among art therapists’ professional characteristics, self-efficacy, stress coping strategies and burnout. The overall burnout of art therapists was influenced by supervision, self-efficacy, and emotion-relieving coping strategy. The three sub-factors of burnout, emotional exhaustion, depersonalization, and reduction in sense of personal achievement were significantly influenced by supervision and emotion-relieving coping strategies.
TL;DR: A two-pronged intervention model that includes a generic intervention to reduce caregiver stress along with a culturally targeted intervention tailored to a family’s language, food preferences, religious practices, gender norms, and other values was recommended to more successfully reach and support these caregivers.
Abstract: This study used an ethnocultural approach to explore how cultural factors influenced ethnically diverse dementia caregivers’ experiences and use of services. A modified thematic analysis of in-dept...
