 This is Barry Sanders. As a pro football player, I know that our bodies aren't built for bone-crushing impact. Brain injuries can be dangerous, resulting in consequences that can last long after the game. One example was uncontrollable outbursts of crying or laughing, possible signs of a neurologic condition called pseudobulbar effect, or PBA. PBA can result from a variety of neurologic conditions or brain injuries. So visit TacklePBA.org and talk to your doctor. Let's tackle this treatable condition together.
