Types, Causes & Prevention

Neurologic injury has many forms resulting from several causes. These broad categories include:

Traumatic Brain Injury (TBI): Damage to living brain tissue caused by an external, mechanical force. It is usually characterized by a period of altered consciousness (amnesia or coma) that can be very brief (minutes) or very long (months/indefinitely). The specific disabling condition(s) may be orthopedic, visual, aural, neurologic, perceptive/cognitive, or mental/emotional in nature. The term does not include brain injuries that are caused by insufficient blood supply, toxic substances, malignancy, disease producing organisms, congenital disorders, birth trauma or degenerative processes.TBI may result from:

Closed Head Injury (CHI)): A subset of a traumatic brain injury in which the skull is not breeched. Occurs when the head accelerates and then rapidly decelerates or collides with another object (for example the windshield of a car) and brain tissue is damaged, not by the presence of a foreign object within the brain, but by violent smashing, stretching, and twisting, of brain tissue. Closed brain injuries typically cause diffuse tissue damage that result in disabilities which are generalized and highly variable.

Acquired Brain Injury (ABI): The implication of this term is that the individual experienced normal growth and development from conception through birth, until sustaining an insult to the brain at some later time which resulted in impairment of brain function.Types of acquired brain injury:
