What regulates the sundowning schedule?
My mother has trouble speaking coherent sentences after around 5:00 or so. It's not tied to actual sunlight, because as the days have gotten longer she's been sundowning earlier. I don't notice a difference if she gets up at 8am or 11am. I don't notice a difference if we have a busy day or a lazy day.
Could it be food related, linked to the dinner schedule? I know I can't defeat the sundowning but just wondering if I can tweak it at all.
