Chances are you’ve bumped your head before. Often, the injury is minor because your skull is hard and it protects your brain. But other head injuries can be more severe, such as a skull fracture, concussion, or traumatic brain injury.
Head injuries can be open or closed. A closed injury does not break through the skull. With an open, or penetrating, injury, an object pierces the skull and enters the brain. Closed injuries are not always less severe than open injuries.
Some common causes of head injuries are falls, motor vehicle accidents, violence, and sports injuries.
It is important to know the warning signs of a moderate or severe head injury. Get help immediately if the injured person has:
A headache that gets worse or does not go away
Repeated vomiting or nausea
Convulsions or seizures
An inability to wake up
Dilated (enlarged) pupil in one or both eyes
Slurred speech
Weakness or numbness in the arms or legs
Loss of coordination
Increased confusion, restlessness, or agitation
Doctors use a neurologic exam and imaging tests to make a diagnosis. Treatment depends on the type of injury and how severe it is.
