One statutory definition of “brain injury” is: any injury to the brain regardless of age at onset, whether mechanical or infectious in origin, including brain trauma, brain damage and traumatic head injury, the results of which are expected to continue indefinitely which constitutes a substantial handicap to the individual, and which directly results in any one or more of the following.
“Brain injury” also includes any injury to the brain that is vascular in origin and is received by a person prior to his or her attaining the age of 22 years. Brain injury does not include alcoholism, Alzheimer’s disease, or the infirmities of aging.
Injury to the brain may also occur as the result of near drowning, heart attack, stroke and infections. This type of injury would usually result due to the lack of oxygen or blood supply to the brain, and, although it is traumatic, is not categorized as a “brain injury” according to the definition above. This can be referred to as an “anoxic injury.”

The concussions that disable, are almost always more symptomatic at 24 hours, than at the 2-4 hour time frame when injured persons are evaluated in the emergency room. Brain injury symptoms escalate over the first 24 hours, because brain injury involves a cascade of events. It is critical that if you are still symptomatic the day after your injury, go back to the same Emergency Room, don’t wait for a doctors appointment. It is critical that the Emergency Room personnel see that the symptoms still persist or have gotten worse.
