Q: What causes autism?

A: A variety of factors are thought to be involved with causing autism. Recent studies suggest a genetic element, possibly a predisposition, is involved in causing autism very early in a child’s in utero growth. Other causes may include infectious, neurological, metabolic, and environmental factors. 

Some of the researchers in the CPEA are focusing their efforts on possible genetic causes of autism. In 2000, scientists in the CPEA Network released the results of two studies that found genes were involved in autism. Additional papers were published in 2001 by CPEA researchers and other NIH-funded scientists as part of an international consortium on genetics research.  These results lead researchers to believe that some people could have a genetic predisposition that makes them more likely to develop autism. The CPEA Network and other NICHD-supported researchers are also looking into other factors that could be involved in autism, in addition to genetics.  For a complete bibliography of autism-related publications from CPEA researchers and other NICHD- and NIH-funded scientists, visit the NICHD autism Web site at http://www.nichd.nih.gov/autism/research/cpea/biblio.cfm.

Even though the research community is uncertain of the exact cause of autism, it is clear that the quality of parenting is not a cause or a contributing factor to autism. Autism is a devastating disease for patients and families; any suggestion that the family caused the condition only worsens the situation.
