[Arrival] Could someone ever “forget” the Heptapod language?

What if someone that learned the language takes amnestics or gets Alzheimer’s? Would it even be possible to get Alzheimer’s if you are fluent enough? Basically, could someone that learned the Heptapod’s language ever get their sense of free will back?

SPOILERS, obviously. 

I think that it would be impossible to forget the language, because once you learn it you would always be learning it. So anything you forget you'd just learn again. 

I think it'd be likely to agitate and worsen Alzheimer's because if you already have trouble keeping up with where you are and what's happening then it's going to be way harder if where you are and what's happening is constantly in flux.
