Brain Injury Terms and Definitions

Musculoskeletal Birth Defect
Diaphragmatic hernia, gastroschisis, omphalocele, limb deficiency, craniosynostosis, bladder exstrophy, cloacal exstrophy, sacral agenesis/caudal regression.

acetylcholine (ACH)
A chemical in the body that carries messages between the nerves and muscles; a neurotransmitter.

Eye Birth Defect
Anophthalmia/microphthalmia, congenital cataracts, glaucoma

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.

Jackson-Weiss syndrome
Many of the characteristic facial features of Jackson-Weiss syndrome result from the premature fusion of the skull bones. The head is unable to grow normally, which can lead to a misshapen skull, widely spaced eyes, and a bulging forehead. Foot abnormalities are the most consistent characteristic, as not all individuals with Jackson-Weiss syndrome have abnormal skull or facial features.

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.

stroke
A condition produced by a blood clot that lodges in an artery and blocks the flow of blood to a portion of the brain, producing symptoms ranging from paralysis of limbs and loss of speech to unconsciousness and death. Less commonly, a stroke may be the result of bleeding into the substance of the brain.

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.

trigeminal neuralgia
A painful condition caused by a disturbance in the function of the trigeminal nerve, which carries sensation from your face to your brain.

Pantothenate kinase-associated neurodegeneration
Pantothenate kinase-associated neurodegeneration (formerly called Hallervorden-Spatz syndrome) is a disorder of the nervous system. The condition is characterized by progressive difficulty with movement and speech
