Down Syndrome Regression Disorder (formerly called Unexplained Regression in Down Syndrome or Down Syndrome Disintegrative Disorder) is a diagnosis that has previously been missed or misdiagnosed in people with Down syndrome.  It is a topic in high interest amongst researchers in the field, including today's podcast guest Dr. Jon Santoro from Children's Hospital of Los Angeles.  Dr. Santoro gave us a review of the topic as well as current research into the diagnosis and treatment of this condition.
