With youth winter sports in full swing, it's important for coaches and parents to know the signs of a concussion, a sports medicine doctor advises. "Because  concussion affects affect thinking," said Dr. Kathryn Gloyer, a primary sports medicine physician with Penn State Health in State College, Pa.

Common people usually think that concussions only happen to football players. But that's not the case. Concussions can happen for all sorts of reasons , including a bike crash, a fall on the playground, or, yes, while playing sports.

Concussion can be remove serious

Another myth is that one does not have to experience a concussion, not even to get hit in the head. A blow to the body that causes the head to move back and forth can cause a concussion as well. A concussion is a type of traumatic brain injury (TBI). Traumatic brain injury sounds scary and concussions, can be quite serious . But the effects are usually temporary and not life threatening.

Symptoms of a concussion can show up right away or days later and include: dizziness, confusion, balance problems, mood or personality changes, problems thinking clearly, headache, blurry vision, nausea or vomiting, sensitivity to noise or light, and an inability to Recall what happened before or after the head injury.

One experience of concussion rises up the risk of another

It's important to note that if a child has experienced a concussion, the risk of having another goes up . And a second concussion can be more severe. So it's important for coaches and parents to be aware of it. Because concussion can affect thinking, the person who suffered the injury might not realize there is a problem.

"Be aware of the symptoms of concussion so you can recognize possible injury to yourself or others, especially young athletes " said Dr. Kathryn Gloyer.

If the injured person is consciousness, you have unequal pupils in the eyes, have seizures or a worsening of symptoms, immediate medical help is needed. "If you suspect that someone has a concussion-especially a child who is not old enough to describe symptoms-make sure he or she sees a health care provider," Gloyer said in a Penn State news release. For a mild concussion, treatment includes physical and mental rest.

" Give the body to break from sports and other strenuous activity, and allow the brain to rest by limiting reading and similar tasks," Gloyer said. "A person with a concussion should be able to get adequate rest and caretaker should monitor for worsening symptoms."

After getting the OK from a doctor, athletes should return to sports gradually, starting with light activity and working up to more intense play. "If a player returns to activity before the body heals from concussion, a second injury could cause prolonged or worsened symptoms, or second-impact syndrome, a rare and potentially fatal condition in which another concussion causes rapid and severe brain swelling ," Gloyer said.
