Head injuries can range from minor to severe and can sometimes result in brain damage. Most head injuries are not serious, but it's important to seek medical help if any symptoms are present after a head injury, as they can be serious even if they are not visible. A severe head injury requires immediate medical attention, as there is a risk of permanent brain damage. Symptoms of a head injury can occur immediately or develop slowly over several hours or days, and may include vomiting, confusion, slurred speech, mood swings, and headaches. If you have been sent home from the hospital with a minor head injury, you should rest, avoid stress, and have someone stay with you for at least the first 24 hours.

Diagnosis and treatment
Head injuries can be classified as either closed or penetrating. In closed head injuries, the head sustains a blunt force by striking against an object. In penetrating head injuries, a high-velocity object breaks through the skull and enters the brain. Most head injuries are not serious, but it's important to get medical help if you or your child have any symptoms after a head injury.
If you have been discharged from the hospital with a minor head injury, you can usually look after yourself or your child at home. Symptoms of a concussion may include a slight headache, feeling sick or dazed, and can last for up to 2 weeks. You can manage these symptoms by using ice packs, taking painkillers, and getting plenty of rest. It is important to avoid driving or operating machinery until you feel fully recovered.
If you have been sent home from the hospital, it is important to have someone stay with you for at least the first 24 hours to monitor for any new symptoms. You may also be advised to see your doctor for a follow-up appointment to check on your recovery.
For severe head injuries, it is important to seek immediate medical attention as there is a risk of serious brain damage. A healthcare professional will assess your brain function using the Glasgow Coma Scale (GCS) and may perform a computerized tomography (CT) scan to check for any bleeding, bruising, or swelling in the brain. Skull x-rays are no longer performed as they do not provide information on brain damage.

Recovery at home
Most head injuries are not serious, but it is important to monitor them closely as they can sometimes result in serious brain damage. Even if the skull is not fractured, the brain can hit the inside of the skull and cause a concussion or bruising. Concussion symptoms can last for a few weeks and may include a slight headache, nausea, or a feeling of daze.
If you have been discharged from the hospital or are recovering at home, it is important to have someone stay with you for at least the first 24 hours to monitor for any new symptoms. During this time, you should rest and avoid stress—it is okay to sleep if you feel tired. You can take painkillers such as paracetamol for headaches, but avoid other pain medicines. Do not drive or operate machinery, and refrain from drinking alcohol or taking sleeping pills or drugs for at least 48 hours. Limit your reading and screen time, and avoid sports for at least 48 hours.
If you or your child experience any of the following symptoms, seek immediate medical attention:
- Unusual behavior, mood swings, or trouble concentrating
- Slurred speech or problems reading or writing
- Numbness, dizziness, or weakness
- Difficulty falling asleep or waking up
- Changes in eyesight or trouble moving the eyes
- Fluid discharge from the nose or ears
- Persistent vomiting or inability to control bowel or bladder
It is important to note that symptoms of a head injury may develop slowly over several hours or days. If you have any concerns or ongoing symptoms, see your doctor. Most adults recover from a mild head injury within 2 days, but symptoms may last for up to 10 days. Children may experience symptoms for up to 4 weeks and may get more tired from their usual activities.

Concussion
A concussion is a type of brain injury that results in a temporary loss of normal brain function. It is characterised by an immediate and transient alteration in brain function, including an altered mental state or level of consciousness, caused by mechanical force or trauma. Concussions can be caused by direct trauma to the head, such as falling, being hit, or being in an accident. They can also occur due to rapid acceleration or deceleration of the head, as seen in whiplash or blast injuries. While many assume that loss of consciousness or external signs of head trauma, like bleeding, indicate a concussion, these symptoms are not always present.
Historically, rest was the standard treatment for concussions. However, newer approaches involve targeted therapy to address specific symptoms. Clinics can help determine the most affected areas and recommend appropriate therapies. Before returning to sports or activities with a risk of contact or further head injury, individuals may need to undergo a thorough medical examination.

Prevention
Head injuries are a common occurrence, with an estimated 1.5 million Americans sustaining a traumatic brain injury each year. While most head injuries are not severe, it is crucial to take preventive measures to minimize the risk of sustaining a head injury and to recognize the signs of a severe head injury that requires immediate medical attention. Here are some preventive measures to consider:
Safety Equipment and Awareness
Always use appropriate safety equipment during activities that pose a risk of head injury. This includes wearing a seat belt when driving or riding in a vehicle, donning a properly fitted helmet when riding a bicycle or motorcycle, and wearing a hard hat in construction or industrial settings. Ensure that helmets are worn correctly, covering the top of the head and forehead with the chinstrap securely fastened.
Avoid Impaired Driving
Never drive under the influence of alcohol or allow yourself to be driven by someone who is impaired by alcohol or other substances. Impaired driving significantly increases the risk of accidents and head injuries.
Learn and Follow Safety Recommendations
Familiarize yourself with safety guidelines for activities that carry a risk of head injury. For example, follow bicycle safety recommendations, sports safety protocols, and guidelines for activities involving children, who are particularly susceptible to head injuries.
Recognize Symptoms of Severe Head Injury
Even if a head injury appears minor, it is important to recognize the signs and symptoms of a severe head injury that require urgent medical attention. These include persistent or worsening headaches, unusual behavior or mood swings, slurred speech, numbness or weakness, difficulty sleeping or waking up, changes in eyesight, and discharge of fluid from the nose or ears. If any of these symptoms occur after a head injury, seek immediate medical attention.
Monitor for Delayed Symptoms
In some cases, symptoms of a head injury may develop slowly over several hours or even days after the initial injury. Monitor yourself or the injured person closely for any new or worsening symptoms, as this could indicate a more severe injury or complication. Delayed symptoms may include nausea, vomiting, confusion, and behavioral changes.
By following these preventive measures and staying vigilant about head injuries, you can significantly reduce the risk of severe complications and ensure prompt medical attention when needed.
