Concussion is the most common form of head injury for athletes.
However, it is important to note that it is not necessary to lose consciousness to have a concussion. Mild confusion or disorientation about who or where you are, what the time or date is, or what you were doing when the injury happened can be signs of concussion. Also note that statistics show that once you sustain a concussion, you are 4 to 6 times more likely to sustain another, even with a mild hit. There are three grades of concussion. Some sports are more likely to result in concussion or more serious brain injury.
