The 4th International Consensus Statement on Concussion (or 4th CIS) was a gathering of leading experts, both clinicians and researchers, in Zurich, Switzerland which occurred in November 2012. This meeting occurs approximately every three years and the experts update the current knowledge and best-practice patterns for the medical management of concussions.
