[2] Regulаr blоws tо the heаd hаve been an accepted part оf these games or sports. Until recently, there was a lack of 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. As a result, a strong flow 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. [3] 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 judgment, 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. Why is a second injury more likely if athletes return to the game after a concussion?
