I don't think the Curse can be cured. This is AoT we're talking about. The world constantly dicks over the characters and is completely unapologetic for it.

As for why Grisha didn't show any signs of aging, maybe he was on the very beginning of his 13th year. Or maybe he did find a cure. Or maybe, it's just a plothole. IDK
