MY mother who has dementia for last 7 years has started having conversations with people whom aren't there. She insists that I acknowledge whomever she talks too even wanting me to give them tea, coffee, or etc. Question, do I go along with this scene or let her know no one is there. My sister & I are her caregivers. And she is never alone. What's the best solution? She has even tried to give us invisible money that she gets from her pretend boyfriend.
