example......all of my life my mother has been unstable, violent behavior, very abusive physically and verbally. When she wants something she plays mind games to get want she wants. As an adult I pulled away from her. But the last year or so......see seems to display signs of dementia. When she wants you to do something and you don't have time.....she has these sudden trips to ER in ambulance and we run test after test, blood work and NOTHING is ever wrong, and the ER doc says dementia and starts talking to her about future care and when he leaves she is so mad and instantly her mind is perfect. We've had MRIs, under care of neurologist and family doctor, blood work. I am literally so confused. I want to help BUT if this is more manipulation I want to walk away from it for my own sanity. Advice/opinions?
