I found the following article below (which is similar to a report published in the current NewScientist ), concerning neonatal jaundice and autism/developmental disorder links; Study ties jaundice to autism risk LOS ANGELES — Researchers may have discovered a possible link between jaundice in newborns and an increased risk of psychological development difficulties, including autism. Danish scientists looked at data on the 733,826 live births in Denmark between 1994 and 2004. In that group, 35,766 were diagnosed with neonatal jaundice, a fairly common illness in babies that usually goes away within a week of birth. During the study period, 1,721 children were diagnosed with a psychological development disorder, and 4,257 children died. Being exposed to jaundice for children born at full term resulted in a 56 percent to 88 percent increased risk of acquiring a psychological development disorder and a 67 percent increased risk for infantile autism. The study was published online in the journal Pediatrics.
