What Is Acquired Brain Injury?

Acquired brain injury (ABI) occurs when a sudden, external, physical assault damages the brain. It is one of the most common causes of disability and death in adults. ABI is a broad term that describes a vast array of injuries that occur to the brain. The damage can be focal (confined to one area of the brain) or diffuse (occurs in more than one area of the brain). The severity of a brain injury can range from a mild concussion to a severe injury that results in coma or even death. Acquired brain injuries are also commonly referred to as traumatic brain injuries (TBI).

Each year, 2 million people in the United States experience a brain injury, and 99,000 suffer from long-term disability. Over five million people today are living with a TBI-related disability. Each year, more than 56,000 people in the US will die following traumatic brain injuries.
