Brain injury; Head trauma

A head injury is any trauma to the scalp, skull, or brain. The injury may be only a minor bump on the skull or a serious brain injury.

Head injury can be either closed or open (penetrating).

  • A closed head injury means you received a hard blow to the head from striking an object, but the object did not break the skull.
  • An open, or penetrating, head injury means you were hit with an object that broke the skull and entered the brain. This is more likely to happen when you move at high speed, such as going through the windshield during a car accident. It can also happen from a gunshot to the head.

Head injuries include:

  • Concussion, in which the brain is shaken, is the most common type of traumatic brain injury.
  • Scalp wounds.
  • Skull fractures.

Head injuries may cause bleeding:

  • In the brain tissue
  • In the layers that surround the brain ( subarachnoid hemorrhage, subdural hematoma,  extradural hematoma )

Head injury is a common reason for an emergency room visit. A large number of people who suffer head injuries are children. Traumatic brain injury (TBI) accounts for over 1 in 6 injury-related hospital admissions each year.

Causes

Common causes of head injury include:

  • Accidents at home, work, outdoors, or while playing sports
  • Falls
  • Physical assault
  • Traffic accidents

Most of these injuries are minor because the skull protects the brain. Some injuries are severe enough to require a stay in the hospital.

Symptoms

Head injuries may cause bleeding in the brain tissue and the layers that surround the brain (subarachnoid hemorrhage, subdural hematoma, epidural hematoma).

Symptoms of a head injury can occur right away. Or symptoms can develop slowly over several hours or days. Even if the skull is not fractured, the brain can hit the inside of the skull and be bruised. The head may look fine, but problems could result from bleeding or swelling inside the skull.

The spinal cord is also likely to be injured in any serious trauma.

Some head injuries cause changes in brain function. This is called a traumatic brain injury. Concussion is a mild traumatic brain injury. Symptoms of a concussion can range from mild to severe.

First Aid

Learning to recognize a serious head injury and give basic first aid can save someone’s life. For a moderate to severe head injury, CALL 911 RIGHT AWAY.

Get medical help right away if the person:

  • Becomes very sleepy
  • Behaves abnormally
  • Develops a severe pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।" data-rx-term="headache" data-rx-definition="Headache means pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।">headache or stiff neck
  • Has pupils (the dark central part of the eye) of unequal sizes
  • Is unable to move an arm or leg
  • Loses consciousness, even briefly
  • Vomits more than once

Then take the following steps:

  1. Check the person’s airway, breathing, and circulation. If necessary, begin rescue breathing and CPR .
  2. If the person’s breathing and heart rate are normal but the person is unconscious, treat as if there is a spinal injury . Stabilize the head and neck by placing your hands on both sides of the person’s head. Keep the head in line with the spine and prevent movement. Wait for medical help.
  3. Stop any bleeding by firmly pressing a clean cloth on the wound. If the injury is serious, be careful not to move the person’s head. If blood soaks through the cloth, do not remove it. Place another cloth over the first one.
  4. If you suspect a skull fracture, do not apply direct pressure to the bleeding site, and do not remove any debris from the wound. Cover the wound with sterile gauze dressing.
  5. If the person is vomiting, to prevent choking, roll the person’s head, neck, and body as one unit onto their side. This still protects the spine, which you must always assume is injured in the case of a head injury. Children often vomit once after a head injury. This may not be a problem, but call a doctor for further guidance.
  6. Apply ice packs to swollen areas.

Do Not

Follow these precautions:

  • Do NOT wash a head wound that is deep or bleeding a lot.
  • Do NOT remove any object sticking out of a wound.
  • Do NOT move the person unless absolutely necessary.
  • Do NOT shake the person if he or she seems dazed.
  • Do NOT remove a helmet if you suspect a serious head injury.
  • Do NOT pick up a fallen child with any sign of head injury.
  • Do NOT drink alcohol within 48 hours of a serious head injury.

A serious head injury that involves bleeding or brain damage must be treated in a hospital.

For a mild head injury, no treatment may be needed. However, watch for symptoms of a head injury, which can show up later.

Your health care provider will explain what to expect, how to manage any headaches, how to treat your other symptoms, when to return to sports, school, work, and other activities, and signs or symptoms to worry about.

  • Children will need to be watched and make activity changes .
  • Adults also need close observation and activity changes .

Both adults and children must follow the provider’s instructions about when it will be possible to return to sports.

When to Contact a Medical Professional

Call 911 right away if:

  • There is severe head or face bleeding.
  • The person is confused, tired, or unconscious.
  • The person stops breathing.
  • You suspect a serious head or neck injury , or the person develops any signs or symptoms of a serious head injury.

Prevention

Not all head injuries can be prevented. The following simple steps can help keep you and your child safe:

  • Always use safety equipment during activities that could cause a head injury. These include seat belts, bicycle or motorcycle helmets, and hard hats.
  • Learn and follow bicycle safety recommendations .
  • Do not drink and drive, and do not allow yourself to be driven by someone who you know or suspect has been drinking alcohol or is impaired in another way.

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.
