MedicalResearch.com: What is the background for this study?
Response: One of the most common questions we get from parents with a child with autism is, "what is the likelihood of having a second or third child with autism, and what is the chance others in our family will have kids with autism?".
To help provide answers to these questions, we started the infant (or baby) siblings study ten years ago. Families having an older sibling with a diagnosis of autism were invited to enroll their next born for assessment and following to see if they also developed autism, and what the likelihood of that happening was. Biological samples like blood, and DNA from blood, were also collected and tested.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There is some evidence to suggest an increased likelihood of neurodevelopmental disorders in relation to hypertensive disorders in pregnancy, however consensus is lacking. Considering hypertensive disorders in pregnancy are among the most common prenatal complication, we decided to synthesise the published literature on this topic by conducting a comprehensive systematic review and meta-analysis.
Our main findings suggest that hypertensive disorders in pregnancy are associated with about 30% increase in the likelihood of autism spectrum disorders (ASD) and ADHD in the offspring, compared to offspring not exposed to hypertensive disorders in pregnancy.
