Autism spectrum conditions in individuals with Möbius sequence, CHARGE syndrome and oculo-auriculo-vertebral spectrum: diagnostic aspects.

The team looked at the kids with three rare syndromes: Möbius, CHARGE, and oculo-auriculo-vertebral (OAV).

They used standard autism checklists like the ADOS and ADI-R. They also watched each child in play and asked parents questions.

The goal was to see how many of these kids also met criteria for autism spectrum conditions (ASC).

Almost half of the kids had ASC: 45 % in Möbius, 68 % in CHARGE, and 42 % in OAV.

But the usual tools missed many cases. Kids with hearing loss, vision loss, or motor problems scored low on eye-contact and gesture items even when they showed clear social-communication issues.

Wulffaert et al. (2009) saw the same problem in Rett syndrome. They also found that severe motor and sensory limits made standard checklists under-count autism.

Provost et al. (2007) showed that nearly all toddlers with ASD have motor delays. Maria’s data now tells us the reverse is also true: kids whose primary diagnosis is motor-sensory often have undetected autism.

Storch et al. (2012) found routine brain MRI rarely helps in high-functioning ASD. Maria’s work adds that fancy scans are even less useful when the child has major sensory loss. Observational schedules beat both MRI and checklists in these groups.

If you assess a child with facial palsy, hearing aids, or spinal issues, do not rely on ADOS alone. Add a second clinician, use play-based observation, and score social intent instead of eye contact. This small shift catches the autism that checklists miss.
