Traumatic Brain Injury Definition

 

Traumatic Brain injuries: Can be classified as either a “penetrating” or “closed-head.” 

 

Penetrating head injuries: Occur when the skull has been compromised by a foreign object, as in the case of a gunshot wound. This type of injury also causes bleeding and the possibility of infection. Penetrating head injuries have the highest morbidity and mortality rates.

 

Closed-head injuries: Typically acceleration-deceleration injuries, caused by a person's head suddenly accelerating (such as from a blow to the head) or decelerating (such as in an automobile collision), which results in the brain striking the inside of the skull.

 

Diagnosis: The severity of traumatic brain injury is often assessed using corresponding scores on the Glasgow Coma Scale (GCS). The scale ranges from 3 to 15, with 3 being the most severe form of TBI and 15 being the mildest. A person with a score below 9 is considered to be in a coma.

 

Symptoms: Physical injury, Aphasia (deficits in language production and/or comprehension), Amnesia, mood swings, depression, anxiety, headaches, dizziness, mental clouding.

 

Treatment:

  •  Intracranial monitoring (Keeping intracranial pressure within normal levels), ventilating cerebrospinal fluid build up within the brain cavity. This is done by drilling a small hole into the skull and inserting a tube, usually into a lateral ventricle. 
  • In terms of medication, mannitol, an osmotic diuretic, can have significant effects on ICP, cerebral blood flow, and brain metabolism. 
  • cognitive therapy, sensory-motor therapy, occupational therapy, speech and language therapy, and physical therapy
  • According to the CDC, there were approximately 214,110 TBI-related hospitalizations in 2020* and 69,473 TBI-related deaths in 2021.1
    • This represents more than 586 TBI-related hospitalizations and 190 TBI-related deaths per day.
    • These estimates do not include the many TBIs that are only treated in the emergency department, primary care, urgent care, or those that go untreated.2
  • People age 75 years and older had the highest numbers and rates of TBI-related hospitalizations* and deaths.1 This age group accounts for about 32% of TBI-related hospitalizations and 28% of TBI-related deaths.
  • Males were nearly two times more likely to be hospitalized (79.9 age-adjusted rate versus 43.7)* and three times more likely to die1 from a TBI than females (28.3 versus 8.4).

Through research, the Kessler Foundation develops new ways to help individuals recover cognitive function and mobility, and equip families and caregivers with the long-term support they need to adjust to living with brain injury.
