Other head injuries
Also known as: Other specified injuries of head
General information only. Anpheros does not diagnose and does not recommend treatment. Talk to a doctor or pharmacist about your situation. In an emergency, call 112 (or your local emergency number).
In short
Head injuries can be minor because the skull protects the brain, but they can also be more severe, such as a skull fracture, concussion, or traumatic brain injury. These injuries are classified as closed if they do not break through the skull, or open if an object pierces the skull and enters the brain. Common causes include falls, motor vehicle accidents, violence, and sports injuries. Immediate medical help is required if an injured person shows warning signs such as a worsening headache, repeated vomiting, convulsions, an inability to wake up, dilated pupils, slurred speech, weakness, loss of coordination, or increased confusion.

Description
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.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
