No Single Link to Autism, Says New Study

According to the Disability Scoop, a new study has found that no single factor can be attributed to an autism diagnosis. Researchers examined 40 previous studies and aspects of a child’s birth and neonatal condition, and how those factors may contributed to receiving an autism diagnosis later in life.

The researchers did find that some issues, such as brain injury, feeding difficulties and low birth weight did increase the risk of autism, but that it is not likely that a single factor can be attributed to an onset of the developmental disorder. The study published in the journal of Pediatrics found that exposure to a number of risk factors increases the chances of autism. Broad class of conditions reflecting general compromises to perinatal and neonatal health may increase the risk, but no single factor can be implicated, said Hannah Gardener of the University of Miami.

The research did find that high birth weight, head circumference and the use of anesthesia had no apparent association to an autism diagnosis later in life.
