About Brain Injury

The brain is the control center of the body, and its function is crucial to most of our daily activities. "Weighing less than sixteen hundred grams (three pounds) the human brain in its natural state resembles nothing so much as a soft, wrinkled walnut.  Yet despite this inauspicious appearance, the human brain can store more information than all the libraries in the world.  It is also responsible for our most primitive urges, our loftiest ideals, the way we think, even the reason why, on some occasions, we sometimes don't think, but act instead." - from The Brain by Richard Restak, M.D. 


Definitions and Causes

The Brain Injury Association of America (BIAA) has developed the following definitions:

A traumatic brain injury (TBI) is defined as a blow or jolt to the head or a penetrating head injury that disrupts the function of the brain. Not all blows or jolts to the head result in a TBI. The severity of such an injury may range from "mild," i.e., a brief change in mental status or consciousness to "severe," i.e., an extended period of unconsciousness or amnesia after the injury. A TBI can result in short or long-term problems with independent function.

Acquired brain injury (ABI) is an injury to the brain that is not hereditary, congenital or degenerative.
Acquired brain injuries 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.


The causes of both types of injuries can be varied, but the main causes for each include:

Brain Injury Statistics

Acquired Brain Injury (ABI) accounts for approximately 35% of brain injuries in the US.1Annual Incidences of ABI and TBI

From 2001 to 2009, the rate of ED visits for sports and recreation-related injuries with a diagnosis of concussion or TBI, alone or in combination with other injuries, rose 57% among children (age 19 or younger).2

Veterans’ advocates believe that between 10 and 20% of Iraq veterans, or 150,000 and 300,000 service members have some level of TBI.3
