Different Types of Brain Injury
Brain injuries are often described as either traumatic or acquired based on the cause of the 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.
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.
Is It JUST a Concussion?
A concussion is a type of TBI caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth.
This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in the brain and sometimes stretching and damaging brain cells.
Medical providers may describe a concussion as a “mild” brain injury because they usually are not life-threatening. Even so, the effects of a concussion can be serious!
