Final Project: The Long Term Effects of Concussions
Posted in Uncategorized on April 14, 2009 by williamslisIt wasn’t too long ago that players in the National Hockey League and university leagues across North America were skating freely without any kind of cranial protection. In fact, up until twelve years ago, many players still opted to have the wind in their hair until both leagues made it mandatory to wear a helmet.
It seems almost ridiculous to think back of a university league when such big, burly men who were ignorant enough to not worry of the damage they could cause their brains when participating in such a high-contact sport. In a game where people cheer when a player is crushed into the glass, upended by a stick or felled by a hard right hook in a heated fight, protecting your head seems to be a given.
And yet, not much has changed from the dangerous era of 1970’s and 80’s hockey.
Many medical studies and awareness campaigns arose in light of the recent death of Ontario hockey player Don Sanderson. Sanderson died of traumatic head injuries sustained when he was involved in a fight during the game, lost his balance, and hit his head on the ice. Had his helmet stayed on, Sanderson might still be alive.
Despite the obvious dangers of engaging in a high contact sport such as football or hockey, another injury resulting from the vicious style of play is a more silent epidemic, but can have the same devastating effects: concussions.
The Mayo Clinic defines concussions as a traumatic injury that occurs when the brain forcefully hits the inside of the cranium wall, usually as a result of a violent or forceful blow. The Clinic divides concussions into three separate categories, based on severity. In a grade 1 concussion, the athlete does not lose consciousness but will experience dizziness or nausea. The symptoms usually disappear after 15 minutes, but the long term repurcussions of the concussion are still prominent. A grade 2 concussion is classified when an athlete is still dazed and nauseated from 15-minutes to an hour after the initial hit. This concussion can cause symptoms (nausea, vomiting, amnesia) that last for two weeks or longer. Grade 3 concussions cause an athlete to lose consciousness for a significant period of time. These concussions are the most serious, as they can cause serious changes in behaviour and sleep patterns, often rendering the person extremely aggressive and agitated. Symptoms of a grade 3 concussion can last for up to six months, and often athletes sustaining this kind of concussion also suffer from post-concussion syndrome, causing concussion symptoms to be recurring for their entire lives.
For one certain hockey player, these recurring symptoms are a real threat.

A University of Montreal study warns players that suffering even just one concussion can cause difficulties in cognitive function and motor skills, thirty years later. Not much research was done before on the long term effects of concussions, but now the players of the helmet-less era are beginning to age, and the long-term side effects of the injury are causing concern.
With the aging of varsity football and hockey players, the emergence of specific mental/physical health problems are being linked to head injuries sustained, most times, more than thirty years ago.
Brain, a medical journal focusing on neurology, studied 19 former athletes (now in their 50s and 60s) who had suffered at least one or two concussions during their athletic careers thirty years ago, and compared them to 21 former athletes who had never been concussed.
The research showed that the athletes who had sustained concussions had poorer memory, shorter attention spans, and reduced motor skills. This study becomes even more relevant when the same researchers studied 19 current athletes who had recently suffered a concussion, and results showed that the athletes had the same motor competence and memory as athletes who were never concussed.
Jon Gellar is a therapist at Concordia University, and has treated many star athletes at Concordia. He has seen first hand how a concussion can affect an athlete.
“Immediately following a concussion, an athlete may lose consciousness. If he doesn’t, he’ll definitely experience what we call the ‘birdies’—you know, like the little birds in cartoons that fly around our head,” Gellar explained, “The athlete can be dazed and hazy.”
“We shine a flashlight into their eyes to detect if their pupils are dilating or not—it’s a basic function of the nervous system, to make he pupil smaller when a bright light is shone in it. Usually, the athletes’ pupils will stay the same if he has a concussion, because the blow to the head interrupted the normal functions of his nervous system. It’s also why he usually has no idea what day or year it is.”
Anywhere from an hour to four hours after the concussion is sustained, Gellar explained, the true symptoms will begin to kick in: nausea, vomiting, intense dizziness.
Dr. Alain Ptito is an assistant professor in the department of Neurology and Neurosurgery at McGill University, in Montreal.
“The problem with concussions is that we know the immediate symptoms,” he said, “But any time your brain suffers that kind of hit, you have to believe that the repercussions won’t be short term.”
“Unfortunately, it’s something we’re only figuring out now,” he said.
Dr. Ptito said that a grade 3 concussion, categorized by a loss of consciousness on the part of the athlete, is the most severe.
“Your brain has been smacked so hard that it temporarily shuts down,” he said, “How can that not have long term effects on your overall health?”
Thought they may be the most severe, “make no mistake,” Dr. Ptito warns, “A concussion is the brain hitting the inside of the cranial wall due to an excessive outside force. No matter the grade or degree, it’s going to affect you.”

It would seem, then, that short-term symptoms of concussions can turn into long-term health issues, thirty years down the line. While current athletes who had suffered concussions were equal with non-concussed athletes in terms of motor skills and memory, in the long term, the concussed athletes slid down a slippery slope of mental issues and physical setbacks.
In a recent interview granted to The Hockey News, former NHL tough guy Keith Primeau weighed in on the severity of concussions.
Primeau, a 15-year NHL veteran who was forced to retire due to recurring post-consussion syndrome symptoms, knows how much the head injuries can change your life.
“I contracted the flu this week, and everything went right to my head. And the (concussion) symptoms start to come back; the headaches and pressure were extreme, but you also got that sense your wires were crossed, and your thought process was interrupted,” he told thehockeynews.com
By his own admission, it took Primeau awhile to realize that symptoms that he suffers from now are related to head injuries that he sustained more than 15 years ago. Severe depression and suicide attempts, for example, was something that he didn’t connect to post concussion syndrome until a University of North Carolina study examined the after-effects of concussions on 3,600 former NFL players. The research concluded that, aside from disintegrating mental and physical health, concussions also led to bouts of depression and suicide attempts.
“Depression was a tremendous part of it for me, but I had a really strong support group, including my wife Lisa,” he said. “And I give her a lot of credit for putting up with me. I wouldn’t paint my picture as all doom-and-gloom or extremely severe, but I know I had some outbursts that were out of character, and on reflection, were a result of concussions.”

Concussions are a serious part of professional impact sports, yet the injury seems to be one that is more silenced. More and more star players in university hockey are being encouraged to “heal faster” and continue to play games despite suffering the serious head injury. The repercussions of their actions and injuries now will affect them for the rest of their life—but it may already be too late.
