NCT01582256

Brief Summary

The study aims to investigate whether neuropsychological function (particularly cognitive flexibility and executive function), functional (assessed by resting functional MRI, rfMRI) and structural connectivity (assessed by DSI), and electrophysiological function (assessed by event-related potential \[ERP\]: mismatch negativity, MMN and P50) can be effective cognitive endophenotypes (biomarkers) for Autism spectrum disorders (ASD).

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)
Sampling MethodNon-Probability Sample
Study Population

The sample (6 groups) consists of 44 individuals with clinical diagnosis of ASD confirmed by the ADI-R and ADOS assessments (22 with CNVs and 22 without CNVs), their unaffected siblings (n=22 for each group) and age-, sex-, handedness-, and IQ-matched school comparison groups (22 for each group).

You may not qualify if:

  • their ages range from 10 to 25 (because all the probands with CNV aged \> 10);
  • both parents are Han Chinese; and
  • subjects and their parents consent to participate in this study for complete phenotype assessments (3 visits of assessments).
  • if they currently meet criteria or have a history of the following condition as defined by DSM-IV: Schizophrenia, Schizoaffective Disorder, or Organic Psychosis.
