| Outline of Final Research Achievements |
Sensory processing abnormalities in individuals with autism spectrum disorder (ASD) is included in the latest diagnostic criteria; DSM-5. However, there is no standard method to evaluate sensory abnormalities in individuals with ASD. We compared objective pain sensitivity for 3 different stimuli. Then, we compared both the subjective pain sensitivity assessed by the visual analogue scale (VAS) and the quality of pain assessed by the short form McGill Pain Questionnaire (SF-MPQ) for maximum tolerable pain intensities of each stimulation. The pain detection thresholds and pain tolerances of ASD were not impaired, which suggests that differences do not exist between groups with regard to the somatic perception of pain. However, ASD were significantly hyposensitive with regard to subjective pain intensity and affective aspects of pain sensitivity compared with controls. Our results suggest that the cognitive pathways for pain processing are impaired in ASD.
