Clinical Trial 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.
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).
