Brain Injury Terms and Definitions

Crouzon syndrome
Many of the signs of Crouzon syndrome result from the early fusion of the skull bones during childhood. Abnormal growth of these bones leads to wide-set, bulging eyes due to shallow eye sockets; eyes that do not point in the same direction (strabismus); a beaked nose; and an underdeveloped upper jaw.

Non-system-specific Birth Defect
Amniotic band sequence

cerebral palsy
A disorder caused by injury to the cerebral area of the brain that occurs before or during birth or in the first few months after birth. Damage to the cerebrum may cause paralysis (palsy) in one or more parts of the body.

endorphins
Naturally occurring molecules made up of amino acids. Endorphins attach to special receptors in the brain and spinal cord to inhibit pain signals.

hematoma
A collection of blood within the brain or on its surface that can cause increased pressure, which can damage brain cells and interrupt blood flow.

Spina bifida
Is a condition that often has disabling consequences. With severe spina bifida, a person’s legs and feet are paralyzed, and there are problems with bowel and bladder control. Learning disabilities are common, and mental retardation sometimes occurs

Guillain-Barre (ge-YAH buh-RA) syndrome
An inflammatory disorder in which the body's immune system attacks the nerves outside the brain and spinal cord (peripheral nerves) and, more rarely, parts of the brain itself.

vascular dementia
A common form of dementia that results either from narrowing and blockage of the arteries that supply blood to the brain or by strokes that cause an interruption of blood flow within the brain.

Alexander disease
Alexander disease is considered one of the leukodystrophies, a group of disorders where the primary abnormality is the inability to maintain the fatty covering (myelin) that insulates nerve fibers in the brain. Alexander disease is a rare disorder of the nervous system that usually begins during infancy or early childhood.
