You have my sympathies. Dementia is a horrible group of symptoms to have. Seeing my family member going from fully functioning to observing slow changes in personality, unsocial behaviors, and having language difficulty has made me appreciate my life, even with nasty tinnitus.I have a sister-in-law with dementia, and during the day, if she speaks, it's understandable, but as the day progresses, the speech becomes out of sync, and it does not make much sense. I'm pretty sure as the day goes on, the brain becomes exhausted and sentence processing is obscure. A really fucked-up disease.
It's very challenging condition, especially when language become unintelligible.
This is why I'm so concerned about Trump running for president and his supporters turning a blind eye to his increasingly obvious deterioration.
