By 12 months, children with autism showed significant declines in social communication and eye contact compared to typically developing children.
Researchers identified critical phases in brain development that may be mistimed in people with Fragile X Syndrome, a leading known cause of autism. The study found these changes occur midway through a baby's development in the womb, which could inform the timing of effective treatments.
The study found that advanced maternal age is associated with a significantly elevated risk of having a child with autism, increasing by 18% for every five-year increase in the mother's age. In contrast, advanced paternal age is only linked to an increased risk when the father is older and the mother is under 30.
