There are two types of injuries that come under the heading of Brain Injury:
A. Traumatic Brain Injury (TBI) is from a jolt or blow to the head (usually from outside of the head) forcing the brain to move beyond its protective layer of fluid and striking the inside of the skull. A mild and temporary TBI is known as Concussion.
B. Acquired Brain Injury (ABI) is a result of disease, multiple or severe TBI(s) or any malady originating from inside the head. Examples include Stroke, Parkinson’s, Epilepsy, Chronic Traumatic Encephalopathy (CTE) and early onset Dementia. Every brain injury is different and may have multiple or unknown causes. The definition of recovery also varies widely depending on a multitude of physical, psychological and circumstantial factors.
