My 84 year old mother has dementia (mid-stage) & lives with me. I've noted that she starts to become agitated/worrisome, argumentative & more confused around 2 PM each day. Initially, this didn't happen until closer to 7pm but over the past 1-2 months I've noted that it has gradually started happening earlier & earlier & to a more intense degree until, as I said, it now starts around 2 PM.
I understand sundowning & I've seen it in others with Alzheimer's or other forms of dementia but I can't recall ever encountering someone who exhibits symptoms of sundowning that clear up approximately a half-hour to an hour before they go to bed. Like, I'm talking not knowing who I am, thinking her parents (who are LONG dead) are gonna be mad because she's not home yet, asking me for "the phone numbers of all of the people who have motorcycles that they want to get in out of the weather", calling me by my name but then saying she's got to call me, sitting for an hour fiddling with her purse trying to figure out how to unzip it to get inside, etc. I'm talking truly bizarre stuff...especially when you consider that, during the day, she is capable of drawing water into a cup from the tap, warming it with the 1-minute "quick button" on the microwave & adding a spoonful of instant coffee all on her own. Anyway, I've been watching her like a hawk for the past 2 or 3 evenings & I've noticed that her argumentativeness & restlessness lessen & her confusion all but disappears about 30 minutes to 1 hour before she goes to bed. Has anyone else seen the symptoms of sundowning appear so early in the day & disappear so suddenly around 9 PM? I've never seen a sundowner improve like that until they've had at least a few hours of sleep.
