Different Types of Brain Injury

Brain injuries are often described as either traumatic or acquired based on the cause of the injury.

Two Types of Brain Injury

Traumatic Brain Injury

Traumatic brain injury (TBI) is an insult to the brain, not of a degenerative or congenital nature, which is caused by an external physical force that may produce a diminished or altered state of consciousness and which results in an impairment of cognitive abilities or physical functioning. It can also result in the disturbance of behavioral or emotional functioning.

Causes of TBI

Acquired Brain Injury

Acquired brain injury (ABI) is an injury to the brain that is not hereditary, congenital, or degenerative. ABIs are caused by some medical conditions, including strokes, encephalitis, aneurysms, anoxia (lack of oxygen during surgery, drug overdose, or near drowning), metabolic disorders, meningitis, or brain tumors.

Causes of ABI

How Common Are Brain Injuries

Currently, more than 3.1 million children and adults in the U.S. live with a lifelong disability as a result of a TBI, and 6.4 million have a disability due to stroke. This translates to more than 22,000 North Dakotans living with disability from an ABI – close to the population of Mandan.
