Dr Willie Stewart is one of Britain's leading neuropathologists. He has become one of the key figures in the campaign to reform rugby's concussion rules. He explains: Second Impact Syndrome is incredibly poorly understood. The significant point, Stewart says, is that adolescent brains can swell uncontrollably after a single bang on the head. The first one causes the blood vessels to become a bit leaky, he says. The second one cause them to become much worse, and that leads to brain swelling. The second blow does not have to be concussive. A glancing blow, a jar, is enough to exacerbate the swelling. Which is why it is essential to remove a player as soon as signs of concussion are detected.
