Why concussions should be taken seriously

The graphic is from another story but the follwing snippet is from an article by Scott Reid from the OC Register:

More than two years after concussions forced him into retirement in 1999, former National Hockey League defenseman Jeff Beukeboom still suffered from the effects of his head injuries.

He couldn't remember things. He forgot what he was talking about in the middle of conversations. Light bothered him. So did the slightest noise. He slipped into depression, was frequently irritable and always exhausted.

"That was my life on a daily basis," the 14-year NHL veteran said. "Waking up every day and hoping you would feel better and you didn't. Every day I woke up and my head felt like an over-inflated basketball. It was 2½ years of feeling like (garbage). I felt like (garbage) every day."

Stories like Beukeboom's will become increasingly common among NHL veterans in the coming years, medical experts predict...

..the total human cost from concussions will not be known for years, even decades. Retired NHL players said they continue to suffer from memory loss, constant headaches, fatigue, depression and other concussion-related symptoms for years after they played their last game. Even after those symptoms wear off, medical experts said those players remain at risk of permanent neurological damage that will affect their daily quality of life.
