Early screening for neurodevelopmental disorders such as autism is important to ensure children have the support they need to gain the essential skills for daily life. The American Academy of Pediatrics recommends that all children be screened for developmental delays , with additional screening for those who are preterm or have a low birth weight. However, the U.
S. Preventive Services Task Force has called for more research into the effectiveness of current autism screening practices. Primarily based on milestone checklists and symptoms, autism diagnoses also currently rely on observations of behavior that often manifests after crucial developmental stages have passed.
Researchers and clinicians are working to develop simple, reliable tools that could identify early signs or risk factors of a condition before symptoms are obvious. While early screening can lead to the risk of overdiagnosis , understanding a child’s developmental needs can help guide families toward resources that address those needs sooner. We are researchers who study the role the microbiome plays in a variety of conditions, such as mental illness, autoimmunity, obesity, preterm birth and others.
In our recently published research on Swedish children, we found that microbes and the metabolites they produce in the guts of infants – both found in poop and cord blood – could help screen for a child’s risk of neurodevelopmental conditions such as autism. And these differences can be detected as early as.
