Adrenoleukodystrophy

Part of speech: noun

Definitions

1. A hereditary metabolic condition involves the buildup of very long-chain fatty acids, resulting in damage to the brain and adrenal glands, along with myelin sheath deterioration
2. This uncommon disorder is characterized by severe neurological impairments and adrenal gland dysfunction due to a lack of an essential enzyme for fatty acid processing
3. A genetic disorder resulting in the accumulation of long-chain fatty acids, leading to neurological degeneration and dysfunction of adrenal glands, often causing myelin damage

Etymology: Adrenoleukodystrophy is a modern medical coinage, not an ancient term, built from three Greek-derived elements. "Adreno-" refers to the adrenal glands, named from Latin "ad" (near) and "renes" (kidneys), since these glands sit atop the kidneys. "Leuko-" comes from Greek "leukos," meaning white, and refers to the white matter of the brain, the fatty insulating tissue that is damaged in the disease. "Dystrophy" comes from Greek "dys-" (bad, faulty) and "trophē" (nourishment), a term used in medicine for degeneration of tissue caused by faulty nutrition or metabolism. The disorder was first described in the 1970s and 1980s, when researchers linked the brain and adrenal damage to a defect in the breakdown of very long-chain fatty acids. The combined name therefore reflects the three organs it affects: the adrenal glands, the brain's white matter, and the nourishment of those tissues gone wrong. Its best-known form, linked to the ABCD1 gene, is also the basis of the 1992 film "Lorenzo's Oil," which dramatized the efforts of parents to treat their son with a fatty acid mixture.
