Brain Injury Terms and Definitions

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.

Central nervous system Birth Defect
Neural tube defects, hydrocephaly, holoprosencephaly, Dandy-Walker malformation

Beare-Stevenson cutis gyrata syndrome
Beare-Stevenson cutis gyrata syndrome is a genetic disorder characterized by skin abnormalities and the premature fusion of certain bones of the skull craniosynostosis), which prevents further growth of the skull and affects the shape of the head and face.

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.

closed head injury
An injury to the head or brain in which the skull remains intact.

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.

cerebellum
The portion of the brain mainly responsible for balance and coordination.

Alzheimer's disease
Severe form of dementia caused by significant deterioration of brain tissue.

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.

amyotrophic lateral sclerosis (ALS)
Also known as Lou Gehrig's disease, ALS causes degeneration of the nerve cells in certain regions of the brain and spinal cord that control the muscles.
