All you need to know about head injuries, and when should you go to the doctor?

 Head injury is injuries to the brain, skull, or scalp. These injuries range from mild to severe and may lead to some health problems.

Common head injuries include:

  • concussion;
  • Skull fractures.
  • Scalp wounds. 

Treatment varies according to the type, location, and severity of the injury. Head injuries may be either closed or open. 

Closed injuries are injuries that do not break the skull. Open “penetrating” injuries are injuries in which the skull is fractured.

It can be difficult to assess the severity of a head injury just by looking. Some minor head injuries bleed a lot, while some serious injuries don't bleed at all. 

Common causes of head injuries

Head injuries can be divided into two categories based on their causes. Head injuries can be caused by:

  • vibration.
  • head strokes;

Head injuries from vibration are more common in infants and young children.

Head injuries from a blow to the head are usually associated with:

  • Car accidents.
  • the fall.
  • physical assaults
  • Sports-related accidents.

In most cases, the skull protects the brain from serious harm. However, injuries severe enough to cause a head injury can also be associated with spinal injuries.

The main types of head injuries


A hematoma is a collection or clotting of blood outside a blood vessel. It can be very dangerous if a brain hematoma develops. 

Thrombosis can also lead to a buildup of pressure inside the skull. This may cause:

  • Unconsciousness.
  • Permanent brain damage.


There can be bleeding into the space surrounding the brain, called intracerebral hemorrhage or subarachnoid hemorrhage. Subarachnoid hemorrhage often causes headaches and vomiting. 

The severity of intracerebral hemorrhage depends on the amount of bleeding, but over time any amount of blood can cause pressure to build up.


A concussion occurs when the impact on the head is severe enough to injure the brain. It is believed to be the result of the brain hitting the rigid walls of the skull or the forces of sudden acceleration and deceleration. The loss of function associated with a concussion is temporary. And repeated concussions can eventually lead to permanent damage.


Any injury to the brain can lead to edema or swelling. Many injuries cause the surrounding tissue to swell, but they are more serious when they occur in the brain. The skull cannot expand to accommodate the swelling. This causes pressure to build up in the brain.

Head injuries: skull fracture

Your skull does not contain bone marrow. This makes the skull very strong and difficult to break. But a broken skull can't absorb the impact of the blow, which increases the possibility of brain damage as well.

axonal injury

It is a brain injury that does not cause bleeding but damages brain cells. Damage to brain cells makes them unable to function. It can also lead to swelling and more health problems that may even lead to death. 

Although not outwardly visible, diffuse axonal injury is one of the most serious types of head injury. This is because the damage occurred on a large scale over more than one area of ​​the brain.

Head injury symptoms

The head contains more blood vessels than any other part, so bleeding on the surface of the brain or inside it is one of the problems that you need to go to the doctor immediately for treatment, but not all head injuries cause bleeding.

Many symptoms of a serious brain injury will not appear immediately. So you should always continue to monitor symptoms for several days after a head injury. Common symptoms of a minor head injury include:

  • headache;
  • Vertigo.
  • A feeling of dizziness and lightheadedness.
  • mild confusion;
  • nausea.
  • Temporary ringing in the ears.

While symptoms of a severe head injury include many of the symptoms of a minor head injury. It may also include:

  • Unconsciousness.
  • seizures;
  • vomiting;
  • Balance problems.
  • Serious confusion.
  • Inability to focus eyes.
  • Abnormal eye movements.
  • Loss of muscle control.
  • Persistent or worsening headache.
  • memory loss.
  • mood changes
  • Clear fluid leaking from the ear or nose.

When should you go to the doctor?

See a doctor immediately if you think you have symptoms of a serious head injury. You should always seek immediate medical attention if you experience any of the following:

  • Unconsciousness.


In the event of a serious head injury, you should contact a doctor immediately. Movement can sometimes make a head injury worse. 

Head injuries are among the worst injuries that can happen to a person. These injuries range from mild to serious injuries that cause serious health problems and may even cause death. So if he has any injury to the head, go to the doctor immediately to make sure that there are no serious complications.
