“Concussion may be caused either by a direct blow to the head, face, neck or else where on the body with an ‘impulsive’ force transmitted to the head.” (Play it Cool, 2010)

What is a concussion?

From the “Play it Cool” website

“Concussion typically results in the rapid onset of short-lived impairment of neurologic function that resolves spontaneously.” Examples include: Nausea, double or fuzzy vision, sensitivity

to light or noise, headache, feeling sluggish, feeling foggy or groggy, concentration or memory problems, confusion

You can suffer a concussion while engaging in sports such as hockey, football, soccer, boxing and other sports, or leisure activities, for example tobogganing

In the past 2.5 years, 200 concussions have been reported

among NHL players (Globe Sports, 2010, Section R7)

“Close to 10% of minor hockey players suffer concussions

each year” (The Globe & Mail: Concussion effects linger for decades, 2010)

“According to the Centers for Disease Control and Prevention, between 1.4 and 3.6 million sports and recreation-related concussions occur each year, with the majority happening at the high school level.” (Science Daily, 2007)

Relevance to students

“Traditional brain scanning techniques such as MRI and CT are helpful in viewing changes to the brain anatomy in more severe cases, but cannot identify subtle brain-related changes that are believed to occur on a metabolic rather than an anatomic level.” (Science Daily, 2007)

ImPACT Test Immediate Post-Concussion Assessment & Cognitive

Testing Used a baseline and for post-concussion comparison) Measures multiple aspects of cognitive functioning

including neurological tests that look at word discrimination, X’s & O’s, colour match, symbol matching, visual attention span (http://www.impacttest.com/)

The Messier Project “... is an all-encompassing grassroots and

educational initiative which aims to change priorities in the sport by encouraging athletes to play smart and choose the best protective equipment.” (http://www.cascadeicehockey.com/the-project.html)

The Technology “Seven Technology is tuned to absorb impact using

lateral displacement, providing the protection of two helmets in the space of one – one for catastrophic hits and one for concussions.” (http://www.cascadeicehockey.com/the-technology.html)
