Signs suggesting that an athlete has suffered a concussion are hard to spot. As a result, diagnosing a concussion often depends on finding out whether an athlete is experiencing concussion symptoms.
The problem is, as study after study shows, chances are high that an athlete who has had his "bell rung" or been "dinged" won't tell anyone he is experiencing concussion symptoms.
Why? There are lots of reasons, but mostly because players fear losing playing time or disappointing the coach, teammates, parents or even themselves if they don't display the toughness our sports culture expects even of our youngest athletes.
