Topic Overview
Most injuries to the head are minor. Bumps,
cuts, and scrapes on the head and face usually heal well and can be treated the
same as injuries to other parts of the body. Superficial cuts on the head often
bleed heavily because the face and scalp have many blood vessels close to the
surface of the skin. Often the injury is not severe, and the bleeding will stop
with home treatment. For more information, see
how
to stop bleeding.
Many head injuries can be prevented. Use
seat belts and helmets, and make your home safe to prevent falls.
Common causes of serious head injuries in adults include:1
- Car crashes. Almost half of all head injuries
occur during a car crash. Teens and young adults are more likely to be hurt in
car crashes than other age groups.
- Falls, which are more likely to
involve children younger than age 5 and adults older than age
60.
- Sports-related injuries and work-related accidents. Men have
about twice as many head injuries as women. Sports-related injuries are very
common but are not always reported.
- Assaults and violent attacks.
Gunshot wounds are the leading cause of death from a head injury.
Head injuries that involve force are more likely to cause a
serious injury to the brain. A
high-energy injury to the head increases the
likelihood of a serious injury even more. It is important to evaluate the
person for signs and symptoms of a head injury after a fall or other type of
head injury.
It is sometimes difficult to tell the difference
between a mild
concussion and a more serious
head injury. A person with a concussion may appear
dazed, stare blankly, or cry for no apparent reason. Nausea, vomiting,
headache, or dizziness may be present. A visit to a doctor is needed anytime
mild symptoms persist. Even if a visit to a doctor is not needed, watch anyone
who has had a head injury carefully for at least 24 hours to see whether signs
of a serious head injury develop.
Occasionally, after a head
injury you may feel as if you are not functioning as well as you did before the
injury (post concussive syndrome). You may have blurred
vision, headache, nausea, vomiting, forgetfulness, or trouble concentrating.
Some people have problems with balance and coordination and personality
changes. These changes may be related to stress from the events surrounding the
accident that caused the injury or from the injury itself. Many people have
symptoms for as long as 3 months after a head injury, and some even have
problems for as long as a year afterward.
When a head injury has
occurred, look for other injuries to other parts of the body that also may need
attention. Difficulty breathing, shock, spinal injuries, and severe bleeding
are all life-threatening injuries that may occur along with a head injury and
require immediate medical attention.
Injuries to the spine, especially the neck, must be
considered when there has been a head injury.
