ALD is the acronym for a rare genetic disease called
adrenoleukodysrophy. Due to its unique pattern of
inheritance, and the fact that any individual may undergo
random gene mutations, this horrible disease can make its
devastating and often lethal appearance without any warning.
ALD does not recognize racial, social, economic, or
religious boundaries. It does, however, manifest
preferentially in males.
It is commonly known, especially to Americans, as the Lorenzo's
Oil disease, named after an Oscar nominated 1993 film, starring
Susan Sarandon and Nick Nolte, which was based on one family's
experience.
ALD affects boys and young men. In the childhood presentation,
which is observed in 35% of ALD-positive individuals, it is usually
diagnosed between the ages of four and ten years old. They
generally have a history of learning disabilities and/or a behavior
issue such as attention deficit disorder (ADD) or attention deficit
hyperactivity disorder (ADHD) while in fact, insulating material in
the boys' brains, the white matter (also known as myelin) is
progressively being destroyed. The disease worsens over several
years, and usually in less than two years from ALD diagnosis, the
child will lose all cognitive, mental, and physical functions, and
deteriorate into a vegetative state leading to death.
Adrenomyeloneuropathy (AMN)
In the adult onset, young men, in their twenties or thirties,
begin to exhibit neurological based motor lesions in their
extremities. These lesions progress over many years and are
inevitably accompanied by severe handicap. In approximately one
third of these patients the central nervous system also becomes
involved. These young men undergo the same mental and physical
deterioration as the previously described boys. The progress of the
disease is slower, usually declining to a vegetative state and/or
death in 3 to 5 years. There is no effective treatment for the adult
onset of ALD, which is commonly referred to as adrenomyeloneuropathy
(AMN).
Addison's Disease
Virtually all ALD positive males suffer from adrenal
insufficiency also called
Addison's Disease. In rare instances adolescent boys and older
men are neurologically affected. Women, who are genetic carriers of
the disease, may also manifest mild neurological signs.
