Structural and Functional Connectivity in Autism Spectrum Disorders
Taiwan130 participantsStarted 2009-01-01
Plain-language summary
Autism spectrum disorder (ASD) has been given a high priority for genetic and neurobiological study. There is no such information in Asian population and no study has conducted using Diffusion Spectrum Imaging (DSI) to investigate the connectivity throughout the world. Moreover, no follow-up study has been done to examine the developmental changes of structural and functional connectivity. We anticipate to establishing a cohort of 50 ASD and their siblings with complete clinical, neuropsychological, brain imaging, and genetic data for longitudinal study on ASD. Our findings will contribute to our understanding of the structural and functional dysconnectivity for ASD and whether dysconnectivity can be an endophenotype for ASD and used as a biomarker for early diagnosis of ASD.

Inclusion Criteria:
The inclusion criteria for the subjects with ASD are:
* that subjects have a clinical diagnosis of autistic disorder, or Asperger disorder defined by the DSM-IV and ICD-10, which was made by a full-time board-certificated child psychiatrist at the first visit and following visits;
* their ages range from 3 to 15 when we conduct the study;
* subjects and their biological parents (and siblings if any) consent to participate in this study for completing clinical and brain imaging assessments and blood withdraw for genetic study (this criteria also applied to the controls).
Exclusion Criteria:
The proband subjects will be excluded from the study if they currently meet criteria or have a history of the following condition as defined by DSM-IV:
* Schizophrenia
* Schizoaffective Disorder
* Organic Psychosis
* severe neurological disease. Moreover, the subjects will also be excluded from the study if they completely cannot cooperate with MRI assessments.
