In October 2013, to address the range of conditions that fall within this category, NC Policies Governing Services for Children with Disabilities published an expanded definition of Traumatic Brain Injury. This definition (found on page 5 of NC Policies) reads as follows:
Traumatic brain injury means an acquired injury to the brain caused by an external physical force or by an internal occurrence resulting in total or partial functional disability and/or psychosocial impairment that adversely affects a child’s educational performance. Causes may include but are not limited to, open or closed head injuries, cerebrovascular accidents (e.g., stroke, aneurysm), infections, kidney or heart failure, electric shock, anoxia, tumors, metabolic disorders, toxic substances, or medical or surgical treatments. The brain injury can occur in a single event or can result from a series of events (e.g., multiple concussions). Traumatic brain injury also can occur with or without a loss of consciousness at the time of injury. Traumatic brain injury may result in impairments in one or more areas, such as cognition; language; memory; attention; reasoning; abstract thinking; judgment; problem-solving; sensory, perceptual, and motor abilities; psychosocial behavior; physical functions; information processing; and speech. Traumatic brain injury does not apply to brain injuries that are congenital or degenerative, but can include brain injuries induced by birth trauma.
