Thank you for the question.
I think that again it goes back to research. In the current drug regime, there's no specific drug plan for children. That means children are typically overdosed or underdosed with the medication, which is a really sad thing.
To me, the contribution that the western world and countries such as Canada make already is incredible, but there needs to be more research and development towards earlier diagnosis as well as greater accessibility to drugs in order to improve the rate of cure. Without those things, it will continue to be an issue.
