Brief Summary

The significance of this project is the first longitudinal study to investigate the changes of neurocognitive functions of children and adolescents with ASD and to identify the potential neuroimaging endophenotype (biomarkers) for ASD in Asian with advanced imaging technique (Tract-based automatic analysis, TBAA; multi-echo resting-state fMRI in addition to single-echo resting-state fMRI). The success of this project will fill the gap of our understanding of longitudinal changes of brain function by neuropsychological and imaging approaches of ASD in Han Chinese in Taiwan, and is anticipated to facilitate the progress of translational research in ASD.

Detailed Description

Autism spectrum disorder (ASD) is a common severe, clinically and genetically heterogeneous childhood-onset neurodevelopmental disorder. Due to its high prevalence, typical autistic symptoms, and severe lifelong impairment without effective prevention and treatment, the developmental change of brain functions in individuals with this study has been recognized as one of the key topics of ASD. The goal of this project is to prospectively investigate the stability and changes of brain functions assessed by neuropsychological tests and neuroimages in a cohort of children and adolescents with ASD who had the first assessment 3-5 years ago.

Specific Aims: To investigate the stability and changes of neuropsychological and structural and functional connectivity among children and adolescents with ASD as compared to age- and sex-matched typically developing (TD) controls; and to identify predictors for these neurocognitive changes across a 3-5 follow-up period.

The investigators will prospectively follow up 70 ASDs and 70 TDs for reassessments of clinical symptoms, neuropsychological functions, and structural and functional brain connectivity. The assessments include ASD symptoms (ASD only: Autism Diagnostic Interview-Revised, Autism Diagnostic Observation Scale; all: Social Responsiveness Scale (SRS), Social Communication Questionnaires (SCQ), Autism Spectrum Quotient (AQ)), other psychiatric disorders (The Chinese version of the Kiddie Schedule of Schizophrenia and Affective Disorder Scale-Epidemiologic version, K-SADS-E), neuropsychological functions (Conner's Continuous Performance Test) and MRI assessments (T1 and T2 templates, Diffusion Spectrum Imaging, resting-state fMRI).
