Alarming statistics are coming out of Ontario concerning the rate of concussion. According to a study published in 2014 by York University, the number of young people attending for concussion treatment in Toronto rose by 50% between 2003 and 2010. Some people think this is a good thing, because it suggests that parents are becoming more aware of the problem.

A world-renouned clinic in Massachusetts defines concussion as a traumatic brain injury that changes the way the brain functions. The effects may include headache, difficulty concentrating and problems with balance, coordination and memory. Even the mildest injury can cause permanent changes to the brain. The most common cause is a bump on the head, with or without loss of consciousness, although they can also occur as the result of rigorous shaking of the head and upper torso.

The evidence of concussion may be very subtle and not even noticeable for days, weeks or months. Symptoms include headache, confusion and memory loss, as well as nausea/vomiting, ringing in the ears, seeing stars, slurred speech or a sense of pressure from within the head. Pre-schoolers may lose interest in their favorite toys, change their sleeping and eating habits, cry a lot and become even more cranky and irritable than the typical toddler.

A trauma to the head does not have to seem serious in order to cause serious brain injury. Many sports players, when injured, insist on continuing to play after receiving a blow to the head. Sadly, this can end in tragedy, as the death of British actress Natasha Richardson, shortly after refusing treatment for a bump on the head while skiing.

People who take part in vigorous contact sports are particularly prone to concussive head injury, especially in the sport of hockey. In this sport, there is a defensive move called bodychecking in which the defensive player throws his entire body weight against the player who has the puck. The defender uses his or her hip, shoulder, upper arm and elbow to make contact.

In 2010, bodychecking involving the player's head or blind side was prohibited; this was to reduce the worrying numbers of concussions involving youngsters. To date, it does not appear to be working; rates of concussion are higher than ever. What is particularly alarming is that female players are suffering more concussions than male players. This is very odd because women's hockey does not permit bodychecking in any form.

The increase in numbers of concussions in female hockey players, and indeed sportswomen in general, is not confined to professional or even college players. Pee wee coaches of girls aged 9 and 10 are reporting high numbers of head injuries. Despite the absence of bodychecking in the women's game, women are experiencing similar, or even higher, levels of concussive head injury.

A chief neurosurgeon at a hospital in Massachusetts suggests that women may be more susceptible to concussions than men and that this merits further study. This increased vulnerability may be because women do not train their neck muscles as aggressively as do men. Higher rates may also indicate that women are more honest about reporting their head injuries.
