Abstract

Early olfactory identification deficits have been associated with neurodevelopmental arrest of limbic-prefrontal networks. These same networks are implicated in development of autistic-spectrum disorders. We aimed to investigate olfactory identification ability in children with high functioning autism (HFA). Fifteen children with HFA (aged 5-9 years) and 15 age-, gender- and IQ-matched controls (CTL) were compared on their performance on a visual analogue of the University of Pennsylvania Smell Identification Test (UPSIT). The hypothesis that children with HFA would exhibit impaired olfactory identification ability was not supported. However, contrary to the relationship found in the CTLs, s..
