Frequently my mother is not able to open her mouth wide enough to get food in. She typically has a voracious appetite. It is difficult to know if is she is choosing not to eat or isn't able to open her mouth. On days when she is not able to open her mouth we have been feeding her with a syringe. She is no longer able to suck liquids through a straw so liquids are administered solely with the syringe. Is this typical for some PSP'ers and what are you doing to maintain fluids and nourishment?
