I am a caregiver for my boyfriends 87 yr. old mother who I feel has dementia or Alzheimer's. I have taken her to the Geriatrics Dr. and she says to me she is fit as a fiddle and I was like REALLY!!!!! Merle used to be a nurse asst. so she likes to get that Dr./Nurse level. She has a very nasty mouth to me, lies, calls me names, when I bring it to her sons attn. she lies to him and says I never said or did those kind of things. Which in turn he thinks I am lying. I feel like I am fricking loosing my mind. So what kind of Dr. do I take her to now? Neurologist?
