Hey, I recognize that condition. It's called Fatal Familial Insomnia, aka FFI. Basically, it's a really rare genetic disorder that causes worse and worse insomnia until a person is barely able to function. They end up eventually going into a coma due to the fact they can't sleep. And it's always fatal.
