Reаd the pаssаge. Then answer the questiоn. Brain Injuries and Spоrts Playing spоrts can be rough, both for professionals and young athletes. There are bumps, collisions, and falls, and sometimes these involve an athlete's head. In some sports, such as boxing and American football, these blows to the head tend to be an obvious part of the game, but they occur in other sports as well: team sports like soccer, hockey, and basketball and individual sports like skiing, ice skating, and skateboarding. Regular blows to the head have been an accepted part of these games or sports. Until recently, there was a lack or awareness of their negative impact. A major blow to the head can lead to a brain injury called a concussion. The skull is hard and the brain is soft. So a strong blow throws the brain against the inside of the skull, which can cause extensive damage to the neurons in the brain. There is no reliable test for concussions, so doctors usually diagnose them by observing a patient's behavior. A patient may become confused and sleepy, have difficulty remembering things, and react slowly. He or she should not be physically active for a few weeks following a concussion so that the brain has the chance to recover from the injury. If a patient ignores these symptoms and does not rest, the impact on behavior and cognitive function could become permanent. New research suggests that the damage from many small, more minor blows to the head may be just as bad, or even worse than one major blow. The effects of these small blows can accumulate. What makes this particularly dangerous is that the effects are not obvious right away. Athletes may not notice that they are injured, so they do not get any treatment. They just keep playing. When athletes with brain injuries return to the game, their judgement, coordination, and ability to focus on the game are often impaired. This makes it more likely that they will be injured a second time. If that injury is a blow to the head, the damage can be very serious. Recent research has shown that young athletes are particularly vulnerable to these brain injuries because their brains are not completely mature. In response, experts recommend that young athletes wear head protection. However, they warn that this can give athletes a false sense of safety, leading them to take unnecessary risks. Their most crucial advice is that adults who are involved in athletics for young people should learn about these injuries. They need to know how to prevent them and how to recognize their symptoms. Athletes who wear head protection do not have to worry about concussions.
