Brain Injury Terms and Definitions

brain plasticity
Theories based on the idea that the brain may have the ability to use surviving brain cells in a different way to make up for those brain cells that are damaged.

Muenke syndrome
The primary feature of this disease is prematurely fused skull bones along the coronal suture, the growth line which goes over the head from ear to ear. This can result in an abnormally shaped head, wide-set eyes, and flattened cheekbones.

Crouzonodermoskeletal syndrome
Crouzonodermoskeletal syndrome is a genetic disorder characterized by the remature joining of certain bones of the skull (craniosynostosis) and a skin disorder called acanthosis nigricans.

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.

Canavan disease
Canavan disease is an inherited disorder of the central nervous system in which affected individuals cannot break down a compound called N-acetyl-L-aspartic acid (NAA). Canavan disease is one of a group of genetic disorders called the eukodystrophies.

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.

enkephalins
(en-KEF-uh-lins). Naturally occurring molecules in the brain. Enkephalins attach to special receptors in the brain and spinal cord to inhibit pain messages. They also affect other functions within the brain and nervous system.

SADDAN
SADDAN (severe achondroplasia with developmental delay and acanthosis nigricans) is a rare inherited disorder of bone growth characterized by skeletal, brain, and skin abnormalities.

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.
