School nurses are the unsung heroes in the academic world. They do everything from treat injuries to identify illnesses, and often, they’re only health professionals who see students on a regular basis. Because school nurses are a student’s first line defense following an injury, it’s important that they be aware of the facts regarding concussion.

Concussions are common.

Concussions are far more common than many realize, and they are a particularly common injury in middle school and high school. As much as 10 percent of a football team or a girls’ soccer team is likely to sustain a concussion each year.

Every concussion is different.

Symptoms vary widely and may take many forms. These can include memory changes, ocular field disruptions, balance disorders, poor concentration, emotional changes, headaches and fatigue. In some cases, students may experience nausea or vomiting, sensitivity to light and noise, or complain about “not feeling right.

Concussions have their own time zone.

Concussions are brain injuries, and until fully recovered, the brain must be given time to heal. Some concussions resolve in two days, while some take two weeks or two months. In fact, healing can take up to one year.

Youth are at higher risk and take longer to heal than adults.

Children are particularly vulnerable to concussion. Because of developmental changes in the brains of children, their symptoms often take longer to resolve than those of an adult.

Students with a concussion must be protected from playing.

Until the injury has resolved, it is imperative that the student avoid further injury by being removed from play and practice. The student should not return until evaluated by an appropriate medical professional. Continuing to play may result in a repeat concussion, which can slow recovery and increase the chance of long-term problems.
