[Personal View] Autism in schizophrenia and its original link to self-disorder: returning a borrowed concept

Autism was introduced by Eugen Bleuler in 1910 as a defining feature of schizophrenia, and it remained so for 80 years. However, the concept was borrowed by Leo Kanner and Hans Asperger to describe another condition (infantile autism) and eventually awareness of autistic features in schizophrenia declined. Today, autistic features are by default considered indicative of autism spectrum disorder, and patients with schizophrenia, who exhibit autistic features, risk being misdiagnosed with autism spectrum disorder and receiving inadequate treatment.
