Summary

The ultimate goals of this study are to identify patterns of familial aggregation with regards to categorical and dimensional approaches of ADHD and neuropsychological measures, to validate the phenotypes and endophenotypes that are close to biological expression of genders underlying ADHD, and to identify the genetic variants close to the etiological genes of ADHD in Taiwanese sample. We propose to replicate the analysis of the candidate genes identified by previous genetic studies on ADHD using the candidate gene association study design (family-based case control study using parental controls) to validate the findings from other research groups. With the accomplishment of these goals, this study will resolve controversies over inconsistent findings in previous genetic studies and contribute to the literature on the validity of ASD using clinical and genetic data.
