A concussion occurs when the head sustains a hard blow and the impact
jars or shakes the brain inside the skull. The rapid movement interrupts the
brain's normal activities and can cause bruising or swelling of the
brain. Although there may be cuts or bruises on the head or face,
there may be no other signs of a brain injury.
A concussion can cause your child to lose consciousness or
act dazed or confused. Your child may not be able to remember what happened or
may vomit. After a mild head injury (concussion), your child may not
feel well, have a mild headache, or have other physical discomforts. These
symptoms usually go away on their own over a few days to 2 weeks.
Occasionally, after a head injury you may think your child is not
functioning as well as he or she did before the injury. Your child
may have problems with ongoing symptoms, such as headache or forgetfulness, or
new symptoms may develop, such as:
- Changes in personality.
- A decreased
ability to talk or feed himself or herself.
- Changes in
how well your child is able to do
physical activities, such as increased unsteadiness that makes it
hard for your child to walk or stand.
Some of these changes may be related to stress from the events
surrounding the accident that caused the injury. However, they may also be
symptoms of a more serious injury or
symptoms of slow bleeding between the brain and the
covering of the brain (subdural hematoma).
