My mother was recently diagnosed with mild mixed dementia (Alz & vascular).
Unfortunately, over the past month or so, she has started to strike breakfast and dinner and only wants to eat 2 pieces of low calorie bread and a few cheese wedges per day.
She has developed delusions that her breakfast oatmeal is making her vomit, in addition to her evening meals. The only thing that has been working is ordering takeout and supervising the consumption on a nightly basis. She won't allow us to cook in her kitchen, so it's either takeout or we bring meals. However, she won't eat anything that comes from the freezer anymore. Every day she finds a reason why something is wrong w/ a certain category of food.
If she doesn't eat enough calories, she can't take her multiple BP meds, so we are in a predicament. She is also refusing any outside help from a meal service or nurse, She lives with my brother, but he doesn't come home until 4PM daily. He is the one supervising dinner, but he's not always successful in getting her to eat.
Asides from sectioning her, we don't see any other way of breaking this cycle. Her PCP "doesn't see the need for an Rx of an appetite stimulant" which blows my mind. Psych wrote off her symptoms as "just the dementia", despite the fact we suspect depression and possible disordered eating.
