Brief Summary:
Tourette's disorder (TD) is a childhood-onset neuropsychiatric disorder, manifesting motor and vocal tics with increased likelihood of comorbid with attention-deficit/hyperactivity disorder (ADHD) and other psychiatric disorders. Literature documents the comorbid condition with ADHD predicts an increased functional deficit among individuals with ADHD. The information about neuropsychological functioning among individuals with TD adn/or ADHD is little in Asian population. This study aims to validate the diagnoses of TD, ADHD, and TD comorbid ADHD by symptomatology, neuropsychological measures, and social adjustment. This is a case-control study with a sample of 30 subjects with TD, 60 with ADHD, 30 with TD+ADHD, and 60 controls aged from 6 to 18. All subjects will receive comprehensive assessment including standard psychiatric diagnostic interviews using (K-SADS-E), behavioral assessments (SNAP-IV, CPRS:R-S, CTRS:R-S, CBCL, YBOCS, YGTSS), social adjustment (SAICA, GCAS), parenting (PBI, APGAR) and neuropsychological assessment (CPT, CANTAB, WISC-III). We anticipate that this study will provide the primitive data to validate the TD and ADHD using neuropsychological and clinical measures.
