Mom is 84, and the dr. and I believe she is in the beginning of dementia. Most of the time, she is right on top of things, but occasionally something will send "red flags" up for me. She also hears "music" at three different places at times, here at my house where she has been living for over 15 months, at her house 200 miles away, and at the hospital in my town and says "you say I need hearing aids and you (me) can't hear that music". If I don't get her up or she doesn't have to get up for an appt. she would sleep 20-21 hours a day. It seems to increase about 1-2 hours per day every year for the past 3-4 years at least. Has anyone else noticed this? She had a sleep study and it just showed restless leg syndrome. She is on meds and then doubled the meds. She says she sleeps more soundly, but to me she sleeps just as much. As a side note, we have an appt. with an elder lawyer for a free consultation in less than 2 weeks. Wish us luck please. Thanks everybody for all of your responses. Sometimes even when it's not my question, it just what I needed to hear!
Does she have a TV in her room? Is there any activity at the house? Even when my mom couldn't walk well any more, she was pretty interested in TV or watching the dog, or us doing things. There was always 'household noise' to keep her awake. :)
As my husband declined (with dementia) he slept more and more. I learned that sleeping more than 20 hours was a sign the end was near. That really doesn't sound like it applies in your mother's case, though.
It does sound like the proverbial vicious cycle. She sleeps a lot, her muscles get weak, she sleeps even more because of weak muscles, and on it goes. Also, arguing with a 7 yo sounds like dementia. Her judgment is impaired. She makes bad decisions about not exercising, her muscles get weaker, she stays in bed longer, get gets no stimulation, her cognitive abilities decline, she doesn't recognize she needs to be up longer, and here we go round the cycle again.
I like ff's suggestion of consulting her cardiologist for a thorough eval, and possibly an order for some rehab. I wonder if in-patient rehab might break into this vicious cycle she has going.
Another possible resource is a sleep clinic. I think I'd start with someone to deal with her depression/dementia, and her cardiologist first. Keep a sleep clinic tucked in the back of your mind if those approaches don't help.
I wish you luck in dealing with this. Please keep us posted.
On another point, that is strange that your Mom's blood pressure doesn't go up after doing exercises... I would have a cardiologist check that out because just walking up stairs would make everyone's blood pressure go up. Even get a second opinion from another cardiologist.
Are you sure she sleeps all of the time she's in bed? Might she be lying awake thinking of things or even reading or doing puzzles? (I am just trying to distinguish between being in bed 20 hours and sleeping 20 hours.)
Does she seem to be sad or depressed? How is her general demeanor and mood? Does she have activities she likes to do when she is awake?
Has there been a recent trauma or loss in her life?
Sorry I have only questions, but maybe if you flesh out the picture a little someone will recognize a pattern and have a more specific response for you.
You mentioned that your Mom's meds were doubled, or did you mean she is now taking twice as many meds? Say for example, her blood pressure meds were doubled, that would zone her out big time.... I take a bit of adjusting to get my own blood pressure meds to a comfortable doze, without me nodding off.
As for hearing music, that could be anything from a filling in a tooth [very rare] to a hearing aid picking up a music radio station. When my Mom got a new hearing aid she was picking up a talk radio show, with some adjustments it did go away.
