Common Questions

What is metachromatic leukodystrophy (MLD)? The disease called metachromatic leukodystrophy (MLD) happens when a person’s genes are different from most people. A person with MLD usually has walking problems or even has a hard time communicating. They cannot get rid of the bad stuff in their bodies, called sulfatides, that limits their ability to walk, talk, and sometimes impacts their behavior. Because of this, your sibling will have extra doctors, medical equipment, medicine, and lots of extra attention. But remember that your family loves you just as much as your sibling!

What are genes? Every person in the world is born with genes. Genes are what give you the color of your eyes, your hair, and they even determine if you are going to be tall or short! Everyone has genes. Genes can make us healthy and strong or in rare cases be a cause of disease. There are several different kinds of diseases that result from genes that don’t work properly, like metachromatic leukodystrophy (MLD) that your sibling has.

Can I catch it? MLD is not contagious and it is very different from a cold or flu. It is something that your sibling was just born with, just like their hair color.

What can I do with my sibling with MLD? Your sibling with MLD may look and act differently, or not be able to do the same things that you can do. You can still play and have fun with them, it just may look different. Some fun ways to interact with your sibling are: - Talking or reading to them - Listening to music or creating playlists with them - Drawing picture or decorating their medical accessories - Making up new games - Watching shows or movies with them

How should I explain what my sibling has to my friends? It all depends on what you want to do and what feels right to you. You do not have to tell your friends anything about your sibling and their condition. You can tell some people but not everyone. You can tell everyone too. It is okay to tell and it is okay to not tell. If you decide you want to share, you can share this page to your friends, details that you know about MLD, or even just tell your friends that your sibling is extra special and that they require extra attention. If you feel comfortable with it, you can even introduce your friends to your sibling. Do what is best for you.

I am feeling angry / frustrated / sad / lonely / jealous / hurt because my sibling has a disease. Any feeling that you have toward your sibling is okay. It is hard to have a sibling with a rare disease and it can cause a lot of emotions that can be confusing. It is important that you talk to your parents about your feelings instead of bottling them up or acting out. If you don’t want to talk to your parents about it, reach out to a trusted teacher or adult instead.

My parents give my sibling a lot of attention, how can I make sure I get attention too? If you feel like you need more attention, talk to your parents about spending more time together, one-on-one without your sibling. You deserve and need attention too! Just remind your parents that you want to spend time with them alone too!

How can I help my parents take care of my sibling? It is great to help take care of your sibling, just remember that you are their sibling first and can take care of them second. The most important thing is that your sibling knows how much you love them. If you want to help, ask you parents where you can fit in. They may have some ideas, like you picking out clothes for your sibling, keeping them company and comfortable, or even helping with feedings. Your parents should guide you through any care responsibilities!

How can I have space and privacy? Make sure to talk to your parents about privacy and let them know your feelings about having a space that is just for you. You can put a sign on your door saying “privacy please”, shut your door, or communicate to your parents about having alone time.
