Overview

Adrenoleukodystrophy describes several closely related inherited disorders that disrupt the breakdown (metabolism) of certain fats (very-long-chain fatty acids).

What are the symptoms of Adrenoleukodystrophy?

Childhood cerebral type:

Adrenomyelopathy:

Adrenal gland failure (Addison type):

What causes Adrenoleukodystrophy?

Adrenoleukodystrophy is passed down from parents to their children as an X-linked genetic trait. It therefore affects mostly males, although some women who are carriers can have milder forms of the disease. It affects approximately 1 in 20,000 people from all races.

The condition results in the buildup of very-long-chain fatty acids in the nervous system, adrenal gland, and testes, which disrupts normal activity. There are three major categories of disease:

Who is at highest risk?

Adrenoleukodystrophy is a genetic disorder, so anyone with a family history of the disorder is at risk. Since the disease is passed down from parents to their children as an X-linked genetic trait, males are mostly affected.

When to seek urgent medical care?

Call your health care provider if:

Diagnosis

Treatment options

Adrenal dysfunction is treated with steroids (such as cortisol).

A specific treatment for X-linked adrenoleukodystrophy is not available, but eating a diet low in very-long-chain fatty acids and taking special oils can lower the blood levels of very-long-chain fatty acids.

These oils are called Lorenzo's oil, after the son of the family who discovered the treatment. This treatment is being tested for X-linked adrenoleukodystrophy, but it does not cure the disease and may not help all patients.

Bone marrow transplant is also being tested as an experimental treatment.

What to expect (Outlook/Prognosis)?

The childhood form of X-linked adrenoleukodystrophy is a progressive disease that leads to a long-term coma (vegetative state) about 2 years after neurological symptoms develop. The child can live in this condition for as long as 10 years until death occurs.

The other forms of this disease are milder.
