Sidney Crosby has had an indefinite loss of playing time related to multiple concussions and the face of the NHL is in doubt of returning to the game. The Pittsburgh Penguin star has recurring "concussion-like" symptoms that include headache among other symptoms. This on the heels of 21 NFL players filing suit against the NFL for serious health implications from concussions stemming from their playing days. Concussions differ from most other sports injuries in that they are neurological damage to brain tissue that coordinates and controls all body functions. A ligament or tendon will heal naturally with tissue regeneration, but intricate nerve tissue in the brain may take longer than a lifespan to return to normal. Testing done to diagnose concussions such as the ImPACT test are used to determine whether or not a player can return to the field or rink. I personally have witnessed athletes that have scored higher on these tests post concussion than on baseline testing and Crosby recently passed his ImPACT test even thought the symptoms persist. CT scans and other diagnostic imaging tests may also be inconclusive which makes this injury even more of a mystery to doctors and trainers. In the example of Sidney Crosby, where he is openly aware of the symptoms, it is imperative that he avoid contact or stimulus that irritate the condition which means that the NHL and the Penguins may be in a long holding pattern in waiting for their star to return. This problem is one that is just beginning to gain the attention that it needs and transgresses into all levels of sports, especially youth leagues where kids sustaining these injuries are kept from school studies and most activities. I am not sure that there is a good answer or solution to the problem, but improvements in equipment, rules and general understanding of the problem at all levels is a must.
