A closed head injury is
to the head that does not cause a break in the skull. Though the skull is intact, the brain and soft tissue can be damaged by violent movement of the brain in the skull. This can lead to bleeding and swelling inside the skull.
This type of injury is often minor but can lead to a traumatic brain injury which can cause a range of symptoms. Brain injury may be caused by the initial trauma or secondary injury. Secondary injury is caused by bleeding and swelling that is severe enough to increase the pressure on the brain. This pressure can lead to secondary damage and symptoms which may take hours to days to develop.
You will be asked about your symptoms and how the injury occurred. A doctor that specializes in the nervous system may be consulted.
Neurological tests will be completed. The tests will include observation of eye movements, limb movements, the ability to follow commands, and coherence of speech. The tests will help assess the impact on the brain tissue. The tests will also mark current level of symptoms to help measure any improvement or worsening.
may be done if there are severe symptoms or certain risk factors but are not always needed.
Treatment will depend on the location and severity of the injury and specific symptoms. Both mental and physical rest will be needed to help any brain injury heal.
Minor (Mild) Injury
Minor injuries can temporarily affect how the brain works. It can affect brain tasks like memory, balance, concentration, judgment, and coordination. With simple rest, nearly all will have a full recovery.
Both mental and physical rest will be needed to allow the brain to heal. This includes limiting mental tasks like work or school. Returning to normal activities too soon can make symptoms worse and slow recovery. A gradual return to activities will also help minimize symptoms and continue recovery.
Return to a sport or recreational activity that was involved with the head injury may take longer. A second head injury before the brain has fully recovered can lead to more serious brain injury and damage.
Moderate or Severe Injury
Moderate or severe injuries can cause a lot of bleeding and swelling in the brain. The brain sits in an enclosed pocket made of protective tissue, a fluid called the CSF, and the skull. The bleeding or swelling of the brain or supporting tissue can suddenly increase the pressure in this pocket. The pressure can damage the brain and make current function difficult. With a closed head injury the skull remains intact which prevent a relief ffrom the pressure build up.
Immediate emergency care is required for moderate or severe head injuries to:
Manage current injury
Decrease risk of further injury
Provide support like oxygen if needed
Medication may be used to help reduce swelling on the brain. The injury to the brain may stimulate seizures. Medication may help to manage or stop these seizures.
Surgery may be needed to help relieve this pressure. Options include:
Making burr holes through the scalp and skull to allow excess fluid to drain out.
—removing a section of the skull to allow room for swollen tissue. May be needed if the brain is swelling.
Regular testing and monitoring will assess how the brain is recovering. It can take months or years for a complete recovery though symptoms should gradually improve during this time. The length of recovery will depend on a number of factors such as severity of injury, overall health, and age. Neurological and psychological testing will help monitor progress and guide rehabilitation.
Rehabilitation services such as physical therapy or occupational therapy may be needed during recovery for people with severe injuries. Therapy may help relearn movement, speech or memory processes, or adjust to challenges during recovery. Counseling may also be needed to manage frustration and anxiety during extended recoveries.
