Concussions – Overview

An Overview of Concussions

A concussion is a form of Mild Traumatic Brain Injury. Concussions are an injury commonly seen in contact sports such as football, soccer, lacrosse and wrestling. Head injuries also occur in significant numbers in sports and activities not necessarily considered contact sports, like field hockey, softball and cheerleading. A concussion can be defined as an impact to the head which causes symptoms of a brain injury that are transient. The most common cause is from an impact to the head by another player, but a smaller percentage occur from head impact onto the playing surface or from equipment, such as a stick, ball or goal post.

The American Medical Society for Sports Medicine defines a concussion as a traumatically induced transient disturbance of brain function. In other words, an impact on the head or body that negatively affects normal brain function that will eventually improve over time.
