On this week’s podcast, studies tracking changes over time. The British Autism Study of Infant Siblings (BASIS) tracked changes in adaptive behaviors and cognitive skills in children at low-risk and high-risk of an ASD diagnosis, based on family history. The results point to the value in monitoring siblings of those with autism. Researchers at Kaiser Permanente tried to measure the prevalence of psychiatric and medical conditions in adolescents and young adults with ASD by studying its members in Northern California. Based on their results, the researchers call for all clinicians to approach ASD as a chronic health condition requiring regular follow-up and routine screening and treatment of medical and psychiatric issues.
