Parents of children with autism have double the odds of having been hospitalized for a psychiatric condition than parents of children without autism, a comprehensive review of Swedish medical registries found.
The findings by researchers at the University of North Carolina at Chapel Hill were published in the May issue of Pediatrics.
The study incorporated data on 1,237 children who had been diagnosed with autism before age 10, as well as about 31,000 controls. Both mothers and fathers with schizophrenia were roughly twice as likely to have a child with autism, the study found. Mothers (but not fathers) with depression and neurotic and personality disorders had an increased risk of having a child with autism.
"This study might help us pinpoint some more genetic ties to more cases [of autism]," said study lead author Julie Daniels.
