developmental delays

The large, multisite California-based study examined associations between specific classes of pesticides, including organophosphates, pyrethroids and carbamates, applied during the study participants’ pregnancies and later diagnoses of autism and developmental delay in their offspring. “This study validates the results of earlier research that has reported associations between having a child with autism and prenatal exposure to agricultural chemicals in California,” said lead study author Janie F. Shelton, a UC Davis graduate student who now consults with the United Nations. “While we still must investigate whether certain sub-groups are more vulnerable to exposures to these compounds than others, the message is very clear: Women who are pregnant should take special care to avoid contact with agricultural chemicals whenever possible.”

In a study of nearly 1,000 mother-child pairs, researchers from the Bloomberg School of Public health found that prenatal exposure to selective serotonin reuptake inhibitors (SSRIs), a frequently prescribed treatment for depression, anxiety and other disorders, was associated with autism spectrum disorder (ASD) and developmental delays (DD) in boys.

Children who were later diagnosed with autism spectrum disorder had excessive cerebrospinal fluid and enlarged brains in infancy, a study by a multidisciplinary team of researchers with the UC Davis MIND Institute has found, raising the possibility that those brain anomalies may serve as potential biomarkers for the early identification of the neurodevelopmental disorder.



The fact that neurodevelopmental impairments are still present at one year after the episode suggests that the CSE event is not having just a transient effect on developmental abilities. The CSE may have a longer lasting impact on future development through a more permanent reorganization of functional brain networks a reorganization that may have already taken place when we first assess these children.

While many intellectual disabilities are caused directly by a genetic mutation in the so-called “protein coding” part of our genes, the researchers found that in their case the answer laid outside the gene and in the regulation of proteins.
