What is the Difference Between Acquired Brain Injury and Traumatic Brain Injury?

The main difference between acquired brain injury (ABI) and traumatic brain injury (TBI) lies in the cause of the injury. ABI is an injury to the brain that occurs after birth and is not hereditary, congenital, degenerative, or induced by birth trauma. TBI, on the other hand, is caused by an external force that damages the brain, such as a blow to the head. Both ABI and TBI can produce similar symptoms and require similar treatments, but they differ in terms of how the injury is sustained.

ABI can be divided into two groups: anoxic and hypoxic. Anoxic brain injuries occur when the brain does not receive any oxygen, while hypoxic brain injuries occur when the brain receives a small amount of oxygen that is not enough to sustain its function. Examples of non-traumatic brain injuries include stroke, near-drowning, aneurysm, tumor, infectious disease that affects the brain (e.g., meningitis), and lack of oxygen supply to the brain (e.g., heart attack).

TBI is defined as an alteration in brain function or other evidence of brain pathology caused by an external force. Examples of TBI include falls, assaults, motor vehicle accidents, and sports injuries. The effects of a TBI can range from mild (concussion) to severe (coma or vegetative state).

In summary, the key difference between ABI and TBI is the cause of the injury: ABI is caused by internal factors, while TBI is caused by an external force.
