Assessment & Research

Why autism must be taken apart.

Waterhouse et al. (2014) · Journal of autism and developmental disorders 2014
★ The Verdict

Stop treating autism as one thing—start measuring each client’s unique profile to ready them for future precision care.

01Research in Context

01

What this study did

Waterhouse et al. (2014) wrote a position paper. They said autism research should stop hunting for one broken brain circuit.

Instead, teams should map each person’s unique brain-behavior mix. Then pick treatments that match that profile.

02

What they found

The paper did not test people. It argued the old ‘one-size-fits-all’ model slows progress.

The authors claim we will find better fixes when we split the big autism label into smaller, precise targets.

03

How this fits with other research

Later papers extend the same idea. Mottron (2021) and Fein et al. (2021) say stop using broad DSM criteria and pick ‘prototypical’ cases by expert vote. Levy (2021) goes further, calling for dimension scores across all kids, not just an autism bucket.

But Müller et al. (2017) push back. They warn dumping the ASD label now could stall real-world trials and funding. The clash is mostly timing: Lynn wants precision first, Ralph-Axel wants to keep the category until new tools are ready.

Müller et al. (2018) then show middle ground: use the label short-term but collect individual brain data in teen years to see true growth, not noise.

04

Why it matters

For you at the clinic, the fight over labels is not abstract. If future trials use brain-behavior profiles, you may get medication or teaching tools matched to each client’s wiring, not to the word ‘autism.’ Until then, keep the diagnosis for insurance, but collect detailed skill and sensory data on every kid. That list will be gold when precision treatments arrive.

03Original abstract

Although accumulated evidence has demonstrated that autism is found with many varied brain dysfunctions, researchers have tried to find a single brain dysfunction that would provide neurobiological validity for autism. However, unitary models of autism brain dysfunction have not adequately addressed conflicting evidence, and efforts to find a single unifying brain dysfunction have led the field away from research to explore individual variation and micro-subgroups. Autism must be taken apart in order to find neurobiological treatment targets. Three research changes are needed. The belief that there is a single defining autism spectrum disorder brain dysfunction must be relinquished. The noise caused by the thorny brain-symptom inference problem must be reduced. Researchers must explore individual variation in brain measures within autism.
