[Fetal alcohol exposure: when placenta would help to the early diagnosis of child brain impairments]

What is it about?

Alcohol consumption during pregnancy constitutes a major cause of neurodevelopmental and behavioral disabilities. Whereas it is possible for clinicians to establish a perinatal diagnosis of fetal alcohol syndrome, the more severe expression of fetal alcohol spectrum disorder (FASD), most FASD children are late or mis-diagnosed due to a lack of clear morphological and neurodevelopmental abnormalities. Several precious years of care are consequently lost. Recent data revealed a functional placenta-brain axis involved in the control of the fetal brain angiogenesis which is impaired by in utero alcohol exposure. Because in the developing fetal brain a correct angiogenesis is required for a correct neurodevelopment, these preclinical and clinical advances pave the way for a new generation of placental biomarkers for early diagnosis of FASD.
