| Outline of Final Research Achievements |
The present study examined the delay discounting as a measure of impulsivity in children with ADHD and autism spectrum disorders (ASD), using a delay discounting questionnaire. We also investigated the relationship between the impulsivity and frontal hemodynamic activities during the delay discounting task using near-infrared spectroscopy (NIRS). The obtained results can be summarized as follows: (1) children with ADHD and ASD showed higher delay discounting rates than typically developing children. (2) In the healthy adolescents, the delay discounting task produced significant activities in the dorsolateral prefrontal cortex (DLPFC). (3) ADHD adolescents treated with pharmacological therapy also showed prefrontal activities during the task. These findings suggest that neuropsychological examination using delay discounting task and NIRS may be useful for diagnosis of ADHD and assessment of the prefrontal hemodynamic response to pharmacological treatments.
