I have seen this happen, too, and it's terrible for everyone involved. Even when a patient has previously expressed a preference for death versus this decay, medical personnel and family don't always go along. It's akin to torture really - the patient is unable to take their own life in such a state, even though a healthy previous version of them requested it. It makes me so angry, as instead of good memories of the person, you get this ~decade of someone else essentially destroying the memories.
