Is it dementia or something related to hearing loss that make my MIL basically repeat about something we JUST said as though she hasn’t been part of the conversation? My husband had just turned up her hearing aids while sat down to dinner. It’s not an isolated incident
When my own Mom did figure out the subject of the conversation she would start talking on the subject even though the context of the subject was different. I believe what your Mom-in-Law is doing is quite normal and probably not related to dementia.
