Potential biomarker for autism spectrum disorder

Researchers report that in cerebrospinal fluid samples from 33 infants, ages 0-3 months, who were later diagnosed with autism spectrum disorder, concentrations of the neuropeptide arginine vasopressin were significantly lower than in samples from infants without autism spectrum disorder; the results suggest a potential early biomarker of children at risk of the disorder, according to the authors.
