Adrenoleukodystrophy is a rare, inherited condition, passed down through a faulty gene on the X chromosome, which mostly affects boys and men. It stops the body breaking down certain fatty acids properly, so they build up and gradually damage the protective coating (myelin) around nerve cells in the brain and spinal cord, as well as the adrenal glands. There are several forms of the condition, and how quickly it progresses can vary a great deal, even within the same family.
In boys, the childhood form usually appears between around ages four and ten, often starting with behaviour or concentration changes that can look like other, more ordinary things — falling behind at school, clumsiness, or vision and hearing difficulties. It can progress quickly from there. Adult-onset forms exist too, along with adrenal problems (Addison's disease) that can appear on their own.
ALD is diagnosed through a blood test and genetic testing. In early-stage childhood ALD, before too much damage has occurred, a bone marrow or stem cell transplant is currently the main treatment able to halt the disease's progression — timing matters enormously, which is part of why early recognition is so important. Steroid replacement is used where the adrenal glands are affected. Several countries now screen for ALD at birth, precisely so it can be caught before symptoms start.
