Leukodystrophies are inherited disorders that are characterized by a progressive breakdown (demyelination or hypomyelination) of the white matter in the central nervous system, caused by different mechanisms involving myelin proteins, as well as lipid and organic acid metabolism. They have to be distinguished from the “umbrella” term leukoencephalopathy, which is used to delineate any disease of the white matter.
