Landmark study finds first biomarker to detect babies at risk of SIDS
SIDS has resisted explanation for generations, but researchers have now found the first biological signal present at birth that distinguishes vulnerable infants from others. Australian scientists discovered that babies who died of SIDS had measurably lower levels of an enzyme called butyrylcholinesterase — which helps regulate the brain’s arousal response — in routine newborn blood samples. That same heel-prick screening already happens in hospitals worldwide, meaning a future test could fit into existing programs with little disruption. This finding gives researchers a concrete target for the first time, and brings the dream of preventing these devastating losses meaningfully closer.
