The Los Angeles Times (8/20, Mohan) “Science Now” blog reports that according to a study published online Aug. 19 in JAMA Pediatrics, “a second child is seven times more likely to be diagnosed with autism if an older sibling has the diagnosis.” Interestingly, “rates for maternal half-siblings suggested that a mother’s contribution to recurrence was stronger than that of the father,” a finding suggesting that “factors unique to the mother and her pregnancy may contribute to autism.”
