Adrenoleukodystrophy (ALD) is an inherited condition caused by a faulty gene. In children with ALD, the body cannot break down certain fatty acids, which are the building blocks of fat. As a result, levels of these fatty acids build up in the brain and nervous system, preventing nerve cells from sending signals to the body. Symptoms of ALD may include difficulty swallowing or understanding speech, impaired hearing or vision, muscle spasms, and seizures. The faulty gene that causes ALD is on the X chromosome. The childhood form of the disease affects boys; symptoms usually appear between ages 4 and 10.

What to Expect

If your child has been diagnosed with adrenoleukodystrophy, we want you to know that you are not alone – the Center for Rare Disease Therapy is here to help. Here’s what you can expect when you come to us for a consultation.

The Program for the Study of Neurodevelopment in Rare Disorders (NDRD) can usually see a new patient within 1 week of scheduling an appointment. To make an appointment, please call the NDRD at 412-692-9955 or send an email to

How long should we expect our first visit with the doctor to take?

You can expect your first visit to take from 4 to 6 hours. Your child will receive a comprehensive evaluation by our experts of the Program for the Study of Neurodevelopment in Rare Disorders and may be seen by several other doctors and health care professionals.

What will happen during our first visit?

Your child will receive a comprehensive evaluation to establish or confirm a precise diagnosis and determine how much the disease has progressed. Because we work as a team at the Center for Rare Disease Therapy, your child may be seen by several doctors, including a specialist in genetic diseases, brain diseases, child development, hearing, and physical therapy.

We understand that the whole family is affected when a child has a rare disease. You know your child better than anyone else. We see each family as our partner in caring for your child. We think the best approach to caring for a child with a rare disease emerges when we combine our depth of experience in rare diseases with your expertise in what’s best for your child.

We will talk with you about what we think is likely to happen with your child in the near future and about options we can suggest for treating and caring for your child. If surgery is an option for your child, we will help you understand what the surgery entails and what you may need to do to prepare for it. We will also talk with you about what you can do at home to care for your child and improve his or her quality of life. Please feel free to ask our specialists any questions you have about your child’s disease, treating and caring for your child, or anything else that is on your mind.

By the end of your visit, you will have a care plan tailored to your child’s needs and an appointment for a follow-up visit in 3 months. You will be introduced to our clinical nurse practitioner, who is available by phone or video conference to help you with any concerns you have between now and your next appointment.

How long might we have to wait for test results?

You can expect to receive a phone call within 2 weeks to explain test results and discuss recommended next steps. Test results are also made available on Children's patient portal, myCHP, which is provided at no cost to patients, parents, and guardians.
