Adrenoleukodystrophy

Adrenoleukodystrophy (ALD) is a degenerative disorder of the sheath covering nerve fibers, known as myelin. A type of leukodystrophy, the victims of ALD are typically male, as the disease is usually inherited in a sex-linked manner on the X chromosome. Leukodystrophies are disorders that affect the growth and/or development of myelin, a complex fatty neural tissue that insulates many nerves of the central and peripheral nervous systems. Without myelin nerves are unable to conduct an impulse, leading to increasing disability as myelin destruction increases and intensifies. Leukodystrophies are different from demyelinating disorders such as multiple sclerosis, in which myelin is formed normally, but is lost by immunologic dysfunction or other reasons.
