Adrenoleukodystrophy and Myelin

Adrenoleukodystrophy and myelin: Where is the connection? Adrenoleukodystrophy. Malnutrition. Also called ALD. Ten years ago, many people were unfamiliar with this very rare childhood illness. However, thanks to the 1992 MCA Universal Film "Lorenzo's Oil", recognition increased. This real feature film shows the struggle of a family whose son has died of this disease and is still saving him and his children. After seeing this movie, I was very interested in ALD and the possible ways to treat or treat it.

Adrenoleukodystrophy (ALD), or Schilder-Addison's disease, is a progressive genetic disease occurring at birth that ultimately affects the adrenal gland and myelin sheath of the central nervous system and eventually causes neurodegeneration. This disease most commonly occurs in male populations and heterozygous females where mutations / defects in the X chromosome lack the protein necessary for binding to very long chain fatty acids (VLCFAs) or Make a malfunction. The inability of the body to degrade the stored fatty acids can cause deterioration of myelin, which weakens the body's nervous system.

X-linked adrenoleukodystrophy is an inherited disorder mainly occurring in men. It mainly affects the nervous system and the adrenal glands which are small glands at the top of each kidney. In this disease, the fat coating (myelin sheath) that separates the nerve and spinal cord in the brain is likely to metamorphose (demyelinate), which reduces the ability of the nerve to transmit information to the brain. In addition, damage to the outer layer (adrenal cortex) of the adrenal gland leads to a specific hormone deficiency (adrenal dysfunction). Adrenal insufficiency causes weakness, weight loss, skin changes, vomiting, coma.

Adrenoleukodystrophy - A type of genetic disease called white matter brain malnutrition that damages the myelin sheath, which is an insulating membrane surrounding nerve cells in the brain. Since ALD patients do not produce enzymes that degrade these fatty acids in the usual way, they accumulate high levels of saturated very long chain fatty acids (VLCFAs) in the brain and adrenal cortex. Loss of myelin and progressive dysfunction of the adrenal gland are the main features of ALD

Adrenoleukodystrophy (ALD) is a rare genetic disorder that causes the accumulation of long chain fatty acids (VLCFAs) in the brain. As VLCFAs accumulate, they destroy protective myelin surrounding nerve cells and cause brain function. Without myelin, the nerve can no longer convey information to the brain. Defective genes of ALD, often referred to as gene mutations, can cause several different but related disorders: adrenal medulla (AMN), Edison's disease, and - the most common and most devastating form - brain ALD . Brain ALD attacks boys aged 4 to 10, usually resulting in permanent physical disability and death within 4-8 years of age.
