The prevalence and profile of autism in Sturge-Weber syndrome.
One in three people with Sturge-Weber also has autism, and even those without the label show clear social-communication gaps.
01Research in Context
What this study did
Jenny et al. (2022) looked at every published paper on Sturge-Weber syndrome. They pulled out autism rates and social skill data from 124 people. The team compared those who had an autism label with those who did not.
This is the first big picture of how often autism shows up in Sturge-Weber.
What they found
About one in three people with Sturge-Weber also met criteria for autism. Even the ones without an autism label still struggled with eye contact, conversation, and friendship skills.
Strong social awareness in some kids can hide classic red flags, so clinicians often miss the signs.
How this fits with other research
Riccioni et al. (2024) saw the same pattern in Sotos syndrome: three-quarters of kids scored high on autism traits. Both papers urge universal screening for rare genetic conditions.
Rieth et al. (2022) found a similar rate—37 %—in Down syndrome. All three groups show an atypical autism profile, so standard tools may under-count them.
Tan et al. (2021) pooled 75 studies and set the general autism regression rate at 30 %. Jenny’s 32–40 % range lines up almost perfectly, showing Sturge-Weber kids follow the same regression curve as the wider autism population.
Why it matters
If you serve a child with a port-wine stain or seizures, add autism screening to your intake. Use both parent report and direct observation; social strengths can mask deficits. Share results with the neurologist so medical and behavioral plans match. Early identification lets you start social skills groups, peer modeling, and caregiver coaching before bad habits take root.

03Original abstract
A systematic retrospective case note review was undertaken to investigate autism diagnostic factors in 124 individuals with Sturge-Weber syndrome (SWS). Social Responsiveness Scale questionnaires were then analysed to explore the severity and profile of autism characteristics in 70 participants. Thirty-two to forty percent of participants had a clinical diagnosis of autism and half of those without a diagnosis showed significant social communication difficulties. Children had a relative strength in social awareness and social motivation, which are typically much reduced in people with autism. This finding may explain why, to date, the diagnosis has often been overlooked in this population. The research therefore suggests that children with Sturge-Weber should be screened to identify social communications difficulties and provided with timely support.
