None of the sounds are intelligible, but most of the time, they sound like very loud laments (wailing, moaning, etc.) Sometimes, it is if she is carrying on a 1-sided conversation, with voice variations that mimic normal speech, except that none of the words can be detected. Most of the time, though, she is lamenting.
She is in mid stage Alzheimer's, and claims to have no physical pain anywhere. Part of that is that she is of the great depression era, when people didn't complain about having pain. She takes great pride in not having pain and often won't say that she has pain, even when she does.
She is declining rapidly and the very loud laments have increased dramatically over the last 3 weeks. They are very disturbing to other people in our household to have her wailing so loudly all night long. Daytime naps also lead to the same loud lamenting.
Occasionally when she wakes up, she is unable to pronounce even basic words. Then after a few minutes, her speech returns to normal, although she can no longer sustain conversation to any normal degree.
Are these vocalizations because the vocal areas of her brain are dying and firing willy-nilly?
