Q:I am an educator and I have been asked for resources re: advanced dementia and reflexive opening of the mouth to eat when assistance being given. An informal caregiver is feeding her spouse who has an advanced vascular dementia. Is there any information that can be given to the caregiver to help her understand what happens during the process of feeding her husband? She believes that because he opens his mouth when a spoon comes near that he is hungry. The unfortunate thing is that the resident is already a large person and is gaining weight.
