Inflammation and neuromodulation in autism

Published November 2022

Autism is a condition that is widely known to be associated with a large amount of diversity in relation to behavioural traits, associated challenges, co-occurring conditions, and underlying biology. This diversity is referred to as ‘heterogeneity.’ Heterogeneity poses challenges when studying the usefulness of specific supports or when studying underlying biological processes in autistic populations, because these are believed to vary between subgroups on the spectrum.

To improve outcomes for children and adults on the autism spectrum, we need to understand which supports work best for different subgroups of autistic individuals. An important first step in this process is the identification of valid and reproducible subgroups in autistic populations. Our study identified four subgroups of children on the autism spectrum within the Australian Autism Biobank.
