My husband had a TIA in June and has other health complications, mostly congestive heart failure. In recent months, if I'm gone anywhere for any length of time, he accuses me of having an affair. He calls the roll of family members and what's wrong about them. He says they don't care anything about him; that they won't come and see him. Who can blame them when he's so difficult to be around? Help!
Maybe try an honest conversation with your husband about the effect of his negativity and how that's hurt people's feelings?
Folks with dementia have some of the symptoms your husband is showing (negativity, paranoia). Tell us more about his life before and after his TIA and you'll get better answers.
