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!
