Autism & ADHD
Do They Run in Families?
Researchers recently reporting in an article by HealthDaily News; Autism, ADHD in One Child Tied to Raised Risk in Siblings, that autism and ADHD are so closely linked that they not only run in families, but each increases the risk of the other in future siblings. Researchers found that younger siblings of children with autism have a “30-fold increased relative risk” of being diagnosed with autism themselves and are nearly four times as likely to be diagnosed with ADHD. In addition to the sibling connection, researchers found that later-born siblings have 13 times increased odds of being diagnosed with ADHD.
Lead researcher Meghan Miller states; “This really provides support for the idea that there are shared familial — probably genetic — mechanisms that underlie these two conditions and link them together.”
