Background

Autism is a developmental condition that can significantly impact social interaction, communication, and behaviour, but reliable diagnosis often occurs only after age 3. Researchers are exploring biological markers in newborns that could help predict autism earlier, allowing for timely intervention.

Research

In this study, scientists analysed blood samples from birth and again in childhood from children later diagnosed with autism, using advanced molecular techniques. They found changes in certain proteins and hormones related to metabolism, immune function, and brain development that were already present in cord blood and, in some cases, still detectable in later childhood.

Potential Impact

These findings suggest that autism-related biological changes begin before birth and can be detected early through blood tests. If validated in larger studies, these biomarkers could help identify at-risk children sooner and guide early support and treatment efforts.
