Diagnostic criteria for Christianson syndrome

Because the severe autism-like condition Christianson syndrome was first reported only in 1999 and some symptoms take more than a decade to appear, families and doctors urgently need fundamental information about it. A new study that doubles the number of cases now documented in the scientific literature provides the most definitive characterization of CS to date. The authors of the study propose the first diagnostic criteria for the condition. “We’re hoping that clinicians will use these criteria and that there will be more awareness among clinicians and the community about Christianson syndrome,” said Dr. Eric Morrow, assistant professor of biology and psychiatry and human behavior at Brown University and senior author of the study in press in Annals of Neurology. “We’re also hoping this study will impart an opportunity for families to predict what to expect for their child and what’s a part of the syndrome.”
