Largest-ever autism risk analysis provides further evidence that genetic and nongenetic factors both contribute powerfully to ASD
May 03, 2014

In scientific terms, environmental factors include a broad range of influences. In autism, these can be as varied as parental age, birth complications, maternal nutrition at conception and exposure to pollution during early brain development.
