I don't know whether my Grandma (92) has dementia or not. It's something that I'm looking into. She keeps whimpering and moaning but she says she doesn't know why and has trouble controlling it. She says it annoys her and she gets upset about it. She seems to sleep fine in her bed, she's ok when she eats, plays games, or rides in the car. If she's sitting in her recliner, she'll starting whimpering, moaning and carrying on, but it's not consistent, it's on and off. So she recognizes that she's making these noises. I don't know if she's in pain or not. Yesterday she said her knee hurt but she wasn't able to describe it. Maybe five minutes later I asked her if anything hurt and she said "no". But sometimes I hear her say "ouch". I don't know what to make of this. She just recently finished antibiotics for a UTI. I noticed an improvement when she started them, but now I don't know . . . She was relatively fine until she started physical therapy for balance and strength issues. She's shown improvement, but she's gone downhill mentally. I don't understand what's going on here. That's what upsets me the most - that I don't know what's going on.
