Concussions

What Is a Concussion?

A concussion is a momentary loss of consciousness and brain function that occurs after a blow to the head. The unconsciousness can last for several seconds, minutes or hours.

A person with a concussion can have a full recovery. Recovery usually occurs within a day. In most cases, if damage occurs, it is mild or insignificant.

If you believe you have a concussion, you should see medical treatment. A doctor will be able to evaluate you and make sure there is no serious bleeding within the skull.

The most common symptoms of a concussion are:

• persistent low-grade headaches
• nausea
• faintness
• vomiting
• blurred vision
• loss of memory

Emergency Symptoms

How is a Concussion Diagnosed?

Your doctor will examine you and test your strength, balance, reflexes and memory. He will also talk to people who were with you when the concussion occurred. The doctor will talk to other people because you may have memory loss or experience confusion. In serious cases, the doctor may take x-rays and MRIs of your head to see if there is internal damage.

Treatments for a Concussion

If there are no complications, little or no treatment is needed. If treatments are needed, they are usually rest, relaxation and medication to relieve pain.
