Relationship Between Sensory Processing and Autism Spectrum Disorder-Like Behaviors in Prader-Willi Syndrome.

Saima et al. (2022) asked adults with Prader-Willi syndrome to fill out sensory and behavior checklists.

They wanted to know if worse sensory scores would line up with more autism-like actions and other problem behaviors.

The team used simple rating forms so the adults or their caregivers could answer without long interviews.

Adults who scored high on sensory problems also scored high on ASD-like and aberrant behaviors.

The link was strong enough that sensory trouble could be used as an early red flag for bigger behavior issues.

Ogata et al. (2018) studied the same PWS adult pool first. They showed that autism-type behaviors drop after age thirty, but food issues stay. Sohei’s 2022 data add that sensory problems may drive those remaining autism-type behaviors even when the behaviors look milder.

Capio et al. (2013) saw the same sensory-repetitive behavior link in kids with Williams syndrome. The pattern now shows up in PWS adults, hinting that sensory overload feeds repetitive or rigid actions across very different syndromes.

Crane et al. (2009) found that almost every adult with classic ASD has extreme sensory scores, but each person’s pattern is unique. Sohei’s PWS adults follow the same rule: sensory profiles vary, yet higher scores still predict more challenging behavior.

If you support adults with PWS, give them a quick sensory screen during intake. When scores are high, plan for more structure, noise control, and visual cues before problem behaviors grow. The same screen can guide choice of leisure or worksite activities, because calming the senses may directly lower ASD-type outbursts and improve day-to-day coping.
