ABIs occur to the brain after birth and result in a change to the brain’s neuronal activity. These shifts in neuronal activity change how nerve cells in the brain function. Usually, the patient’s functional ability decreases noticeably.
Acquired brain injury is an umbrella term for all brain injuries.
ABIs can be separated into two categories: traumatic and non-traumatic. Traumatic ABIs are called traumatic brain injuries (or TBIs). Usually, if you hear of an ABI, it is a non-traumatic injury.
