Impaired odor identification ability and olfactory hedonic capacity in children with elevated autistic traits

Atypical olfactory function in autism spectrum disorder has been documented numerous studies, but little is known about its occurrence individuals with autistic traits. The aim of the current study was to investigate odor identification ability and hedonic capacity children We recruited 415 measured their traits by Short Autism Spectrum Quotient. Universal Sniff (U-Sniff) test used measure capacity. Olfactory also using children's version Chemosensory Pleasure Scale (CPS-C). Odor CPS-C were negatively correlated Children higher exhibited poorer trait intact state pleasantness. These results pertaining may be endophenotypic markers for disorder. Practical Applications Our extends knowledge on high provides a new perspective In addition, our findings suggest testing provide approach detecting understanding autism.
