There are more than a million cases of concussion each year in the United States.
A concussion may result when the head hits an object or a moving object strikes the head. A concussion can result from a fall, sports activities, and car accidents. Significant movement of the brain (jarring) in any direction can cause unconsciousness. How long a person remains unconscious may indicate the severity of the concussion.
Often victims have no memory of events preceding the injury, or immediately after regaining consciousness. More severe head injuries can cause longer periods of memory loss (amnesia).
Usually, a person has the most memory loss immediately after getting hurt. Some of the memory comes back as time goes by. However, complete memory recovery for the event may not occur.
Bleeding into or around the brain can occur with any blow to the head, whether or not unconsciousness occurs. If someone has received a blow to the head, they should be watched closely for signs of possible brain damage.
It can sometimes cause the victim to go into a coma. That is really all I know.
A concussion.
No. A concussion is caused by a blow or fall on the head. Heat exhaustion is caused by staying too long in the heat.
Its very unlikely but possible. Why do you ask?
cerebrovascular accident
In motor vehicle accidents, concussion can occur without an actual blow to the head. Instead, concussion occurs because the skull suddenly decelerates or stops, which causes the brain to be jarred against the skull.
Young children are likely to suffer concussions from falls or collisions on the playground or around the home. Child abuse is, unfortunately, another common cause of concussion.
a concussion, internal bleeding
Only if the chest injury causes you to hit your head.
Post concussion syndrome is a diagnosis given to someone who has been affected by a concussion. These people exhibit persistent problems due to the concussion even after they should have healed.
A concussion
If concussions aren't treated properly (such as going to the hospital). The person with the concussion can develop what's called second impact syndrome. It's called this because if they get hit on the head again, it can cause follow-up brain bruising. Which can cause permanent damage to the brain.
A double concussion is a concussion that immediately follows the first concussion, or occurs before the injured party is asymptomatic.
