She’s 74, she already has dementia and is under treatment for cancer (chemotherapy). We have known for the past two years she has early stage of dementia and have been working with physical therapy/occupational/and social worker to make sure we are doing all we can. However, recently it appears her body is locking up, her motor skills have diminished (she has trouble walking) or picking up her feet to walk. Holding food in mouth after chewing has occurred or holding fluids in her mouth instead of swallowing. She has had her arm shaking as though she was cold, but it appears to be a nerve issue too. However, it will go away like nothing is happening. This just started the past two weeks. We are getting her to the doctor but wanted to know is this moving into the next stage or even worse? She's been taking pills to help her memory as well as have a person to come into the house and help her but she still forgets to eat if we don't remind her. The falling and not trying to catch herself is scary because its as if she doesn't realize it until it's too late.
