My MIL (moderate ALZ) follows a pattern where some months she eats a lot, even double meals and is hungry. Then the next couple of months, reduced eating, takes full plate but ends up throwing out half of the food and we get worried if there is an underlying issue. Is this a pattern for ALZ patients? She has high diabetes and is on medication and insulin but has no other ailments and there has been no changes in the medications. She looks healthy.
