Increase in Concussion Awareness

Today the NY Times reported about  a research study done by the CDC that concluded that in the past 8 years there has been a 60% increase in the number of people going to hospitals to treat concussions. 
In the article: 

Dr. Robert Cantu said- “Some people will say that the numbers go up because the number of concussions is going up, but I don’t believe it is.” 

What do you think? Do you think the number of concussions has gone up or that people are reporting them more?
