Okay kiddo, do you know what muscles are? They're the parts of your body that help you move around and do things like run, jump, and even eat.
Sometimes, a special kind of sickness called spinal and bulbar muscular atrophy can happen. This is when a person's muscles slowly start to get weaker and weaker over time.
"Spinal" means that the sickness affects the muscles in a person's spine, which helps them stand up and walk. "Bulbar" means it affects the muscles in their throat and mouth, which helps them swallow and speak.
This kind of sickness mostly happens to grown-up men. But don't worry, not everyone gets it! Sometimes it's because of something called a "gene" in their body that isn't working right. But it's not anybody's fault if they get it, and it's not something you can catch like a cold or flu.
Doctors can help people with spinal and bulbar muscular atrophy feel better by giving them some special medicine or therapy. But unfortunately, there's no cure for it yet.
