What is Second Impact Syndrome?


In the event of a concussion, the danger of Second Impact Syndrome (SIS) is something that should be taken very seriously. SIS causes rapid and severe swelling of the brain and can occur if a person sustains a second concussion before their first one has properly healed. SIS is rare but can be fatal.

Concussion Recovery


A single concussion does not need to necessarily impact someone’s future participation in sport if they allow the brain to properly heal. Determining if an athlete is ready to return to sport is a decision that requires careful evaluation and management to avoid re-injury. The latest consensus statement on concussion in sport includes the following strategies for gradual return-to-sport and return-to-school.

Return-To-Sport Strategy

The recovery process following a concussion and the eventual return to sport decision should follow a graduated rehabilitation strategy. This strategy continues to evolve to stay up-to-date with the latest research.

All athletes should be managed by the same standards with no special allowances given for their athletic ability or the needs of the team.

After an initial rest period of 24-48 hours, the athlete can begin symptom-limited activity. The athlete should be monitored by a healthcare professional and only advance to the next step when they are free of concussion-related symptoms. Learn More>>

Return-To-School Strategy

It’s important to help and support students who are returning to school following a concussion. Cognitive difficulties, such as learning new materials or remembering a previously learned curriculum may be challenging. Depending on the type of symptoms that the student is managing, various accommodations may be requested, such as modifications to their schedule, reduced cognitive loading, extra support or extended learning times. Developing the appropriate return to learn plan should be done in collaboration with the athlete, the family, the teachers and your medical professional. Learn More>>>
