Adrenoleukodystrophy (ALD) is a genetic disorder that damages the myelin sheath protecting nerve cells. The buildup of fatty acids in the brain, nervous system, and adrenal glands leads to progressive neurological and hormonal problems. Early detection and treatment can slow the disease and help manage its symptoms.
What are the symptoms?
- Behavioral changes and learning difficulties, especially in childhood-onset ALD.
- Muscle stiffness and weak or unsteady walking.
- Bladder and bowel problems.
- Fatigue and general weakness.
- Signs of adrenal insufficiency include low blood pressure, skin changes, and hormone imbalance.
Why does this disease occur?
- ALD is caused by a genetic defect on the X chromosome.
- The body cannot break down very long-chain fatty acids (VLCFAs).
- VLCFA buildup damages the myelin sheath and impairs nerve function.
Who is at risk?
- Males are more severely affected due to X-linked inheritance.
- Female carriers may develop mild symptoms.
- Family history increases the likelihood of ALD.
What are the possible complications?
- Progressive brain damage (white matter deterioration).
- Rapid neurological decline in childhood-onset ALD.
- Adrenal gland failure, known as Addison’s disease.
- Movement limitations, seizures, and cognitive decline.
When should you see a doctor?
- If a child shows learning difficulties or behavioral changes.
- Signs of muscle stiffness or poor coordination.
- Symptoms of adrenal insufficiency include fatigue, low blood pressure, or skin changes.
- Family history of ALD.
How is this disease diagnosed?
- Blood tests: Measure VLCFA levels, evaluate adrenal function, and detect genetic mutations.
- MRI scans: Detect white matter damage in the brain.
- Vision screening: Monitors disease progression in males with no other symptoms.
- Skin biopsy/fibroblast culture: Measures VLCFA levels in some cases.
What are the treatment options?
- Stem cell transplant: Can halt or slow disease progression if done early.
- Adrenal hormone replacement: Corticosteroids treat adrenal insufficiency.
- Medications: Relieve stiffness, seizures, and other symptoms.
- Physical therapy: Reduces muscle rigidity and improves mobility; aids may be needed.
- Gene therapy: Experimental option showing promising results in cerebral ALD.
How can you take care of yourself at home?
- Maintain regular medical checkups.
- Monitor adrenal function consistently.
- Support mobility through exercises or therapy.
- Make the home safe to prevent falls.
- Track changes in behavior, cognition, or movement.
How can this disease be prevented?
- Genetic counseling for families with an ALD history.
- Prenatal or early genetic testing for at-risk families.
Frequently Asked Questions (FAQs)
Q1. Can girls develop ALD?
Yes, female carriers may show mild symptoms, often in adulthood.
Q2. Is there a cure for ALD?
Currently, there is no cure. Treatments like stem cell transplant or gene therapy may slow disease progression.
