MC has it. I tried looking it up but was redirected to Neotenic complex syndrome. Apparently the body stops aging at a certain point, but not all at once at the same time, which leads to the development of diseases and issues that can cause an early death. basically some parts aged on, others didn't, some were at a different age etc. It's a scary disease. I think the author took inspiration from it and turned it into something less scary for the story. Not a bad idea.
