Brief Report: Sensory Features Associated with Autism After Controlling for ADHD Symptoms.
Sensory issues ride with autism itself, not with its ADHD hitchhiker—so always assess and treat them separately.
01Research in Context
What this study did
The team looked at 61 autistic kids . They asked parents to fill out three short forms: one on autism traits, one on ADHD symptoms, and one on everyday sensory issues like loud noises or scratchy shirts. Then they ran a math test to see if sensory scores still predicted autism traits after removing any part explained by ADHD.
What they found
Sensory sensitivity stayed a strong predictor of autism traits even when ADHD scores were held constant. In plain words, the kids who hated tags, sirens, or fluorescent lights still looked more autistic on paper, and that link was not just because they also had hyperactivity or attention problems.
How this fits with other research
Dube et al. (1991) first showed that autistic children have slower brain-stem sound timing. MacFarland et al. (2025) now show the sensory issue is still there after stripping out ADHD, proving the link is autism-specific, not a side effect of attention problems.
Bolte et al. (2013) found narrower peripheral vision in autistic teens, while Lortie et al. (2017) saw normal early sound detection but poor orienting to voices. Together these papers build a picture: basic detection can be intact, but higher-order or everyday sensory responses remain atypical—and the new data say that atypicality is core to autism, not borrowed from ADHD.
Tkalcec et al. (2023) used the same “remove the overlap” trick, holding callous-unemotional traits constant to clarify empathy gaps. C et al. repeat the tactic for ADHD and sensory issues, strengthening confidence that the leftover variance is true autism variance.
Why it matters
If you treat sensory meltdowns as “just ADHD seeking stimulation,” you may miss the real trigger. Screen every autistic client with a quick sensory checklist—even when hyperactivity is loud. When you write behavior plans, add sensory breaks or modified environments before you tweak attention prompts. The payoff is fewer explosions and clearer data on what is autism versus what is attention-driven.

03Original abstract
BACKGROUND: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and adolescents with autism aged 6-17 years. METHODS: The sample included 61 children and adolescents with autism. The Sensory Profile was used to examine Dunn's quadrant model (seeking, sensitivity, avoiding, registration), ADHD symptoms were measured using hyperactivity and attention problems BASC-2 T-scores, and autistic traits were measured using the AQ. RESULTS: After controlling for age, IQ, sex, and ADHD symptoms, Dunn's sensitivity quadrant predicted autistic traits. CONCLUSIONS: Findings provide insight into the phenotype of autism and ADHD. Sensory sensitivity may be unique to autism over and above elevated ADHD symptoms that are commonly seen in this population.
