Autism phenotype versus registered diagnosis in Swedish children: prevalence trends over 10 years in general population samples

This is the authors' abstract. We don't add key points for this paper.

The prevalence of the autism symptom phenotype has remained stable in children in Sweden while the official prevalence for registered, clinically diagnosed, autism spectrum disorder has increased substantially. This suggests that administrative changes, affecting the registered prevalence, rather than secular factors affecting the pathogenesis, are important for the increase in reported prevalence of autism spectrum disorder.
