For individuals with Down syndrome and their families, one of the most critical areas of development is communication. Today, we are excited to highlight a groundbreaking research initiative that promises to build a brighter, more articulate future for children with Down syndrome.
Researchers at the UC Davis MIND Institute are launching a significant five-year, $5.5 million study, funded by the National Institutes of Health (NIH), to map the landscape of language development in children with Down syndrome. Led by Professor Angela John Thurman, this ambitious project aims to answer the questions that families ask every day: How will my child’s communication skills develop? What milestones should we look for?
“Most children with Down syndrome have delays in developing expressive communication,” Thurman explained. “We know these delays are common and that kids develop at different speeds, but we still don’t know enough about how their communication skills change and grow.”
Down syndrome, which occurs in about 1 in 700 live births, is caused by an extra copy of chromosome 21, affecting both physical and cognitive development. A common challenge is in expressive communication—the ability to share thoughts, wants, and feelings through gestures, sounds, pictures, sign language, or spoken words.
Without a clear, evidence-based roadmap, parents and clinicians are often left navigating this journey without a guide. As Thurman notes, “That often means waiting to see how things go or using a one-size-fits-all approach.” This lack of personalized insight can delay crucial interventions that could maximize a child’s potential.
The study will follow 168 children with Down syndrome between the ages of 18 and 54 months—a critical window for language acquisition. By combining parent interviews, skill tracking, and analysis of communication recordings at regular intervals, the research team will create a detailed picture of how language emerges.
“We’re using approaches that are familiar and useful to families and providers,” Thurman said. “By combining these tools with rigorous research, we should be able to develop a more accurate and meaningful guide — like a roadmap specifically for children with Down syndrome.”
This research has the potential to change support strategies. Currently, language interventions vary widely, and data on their effectiveness is limited. The insights from this study will empower healthcare providers to move beyond a generic model toward truly customized care.
“As we learn more about the different ways people with Down syndrome learn and grow, professionals will be better able to create tools and supports that are more personalized and better timed,” Thurman stated.
Personalized, timely intervention is the cornerstone of effective care. This landmark study by UC Davis resonates deeply with our commitment to advancing health through science and deep understanding. By shedding light on the unique developmental pathways of children with Down syndrome, this research paves the way for more effective therapies and support systems that honor each individual’s journey.
The ultimate goal is one we wholeheartedly share: to improve the quality of life for children with Down syndrome by giving families and professionals the knowledge they need to support communication in the most effective way possible.
We will be watching the progress of this vital study with enormous anticipation and hope.
