I read your other post where you told me about your mother's Parkinson's. I'm really sorry she's dealing with two diseases. Sometimes changing the delivery of a medication can affect the patient. Extended release medications sometimes don't break down in the gut on some people, which could explain the symptoms. But I'm wondering if this isn't her Parkinson's. When it advances, a month can make a marked difference in progression. In either case, you may need to contact her prescribing doctor.
It may be possible, since Namenda is discontinuing its regular strength, that a generic may be coming on the market soon, which could possibly have a nonextended release dosage.
I also read a post from last month where you were dealing with your mother's sleep. My mother slept around 20 hours a day too. She chose not to take Parkinson's medications and since it didn't bother her to sleep, we let her. We just had to watch for bedsores, but she only had one very small one on one ear because she slept mostly on one side. We were very fortunate that she didn't get more, but I personally bathed her and kept an eye on her skin.
