People mistake curing stuttering with suppressing it. There is no "cure". You can learn different methods to speak differently or ease into their words, but there is no pill, injection, or medicine that can cure it. It's called a disorder for that reason. If it was curable, it would be labeled as a disease. "The words "disorder" and "disease" are sometimes used interchangeably, but there are clear differences between them. A disorder is a group of symptoms that disrupts your normal body functions but does not have a known cause, while a disease is a medical condition with an identifiable cause."
