Can animals be autistic?

The answer is obviously “no”, however, animal models are necessary to help understand brain circuitry and improve interventions and supports for not just core symptoms but associated issues like anxiety, OCD, seizures and GI issues. Scientists view behaviors consistent with an ASD diagnosis differently, and this has created some problems in interpretation of animal model data. This week’s #ASFpodcast will break down a recent paper in Genes, Brain and Behavior which addresses inconsistencies in the literature and makes recommendations on how researchers should shift how they think about how they can replicate features of ASD in a model system.

Environmental factors as both causes and interventions?

Environmental exposures, including toxic chemicals, can contribute to the causes of ASD. But how do other environmental factors, like behavioral supports, work in the brain to improve behaviors associated with ASD? For this, you need a broad interpretation of the term “environmental” and an animal model so you can see the mechanism involved. Studies show while environmental factors can contribute, they can also provide modifications in cellular and molecular function which support learning and improved developmental trajectory. Finally, on a different topic, are autistic adults more likely to be involved in a crime compared to other groups? No, they are not, but there are factors which affect the risk of being involved with the criminal justice system, at least in the UK. Read more in the studies below.

New ways to solve old problems

This week’s podcast focuses on innovative methodologies to understand how to reach black families, understand why and when autistic people prefer not to look at faces and how interventions can improve conversation and social communication. They use culturally and racially matched mentors, old home video tapes (keep taking those!) and machine learning to look not just at novel methods but novel ways of studying a particular outcome.
