Leukodystrophy Definition:
Leukodystrophies are a group of very rare, progressive, metabolic, genetic diseases that affect the brain, spinal cord and often the peripheral nerves. Each type of leukodystrophy is caused by a specific gene abnormality that leads to abnormal development of one of at least 10 different chemicals that make up the white matter (myelin sheath) of the brain. The myelin sheath is the protective covering of the nerve and nerves can’t function normally with out it. Each type of leukodystrophy affects a different part of the myelin sheath, leading to a range of neurological problems.
Other definition of Leukodystrophy:
Leukodystrophy: A disorder of the white matter of the brain, the part of the brain that contains myelinated nerve fibers. The white matter is white because it is the color of myelin, the insulation covering the nerve fibers. (The white matter is as opposed to the gray matter, the cortex of the brain which contains the nerve cell bodies). The white matter is involved in the conduction of nerve impulses in the brain.
