I'm trying to figure out what is going on with my 92 y/o Grandma since she can't or won't tell me. Over the last 8 months or so, she has been making more groaning and whimpering sounds. She denies anything to be wrong and says the sounds are soothing to her. In January, she started making these sounds in the middle of the night. I told her everynight for a week in February that she needs to stop making these sounds during the night because it keeps everyone awake. I told her that if she keeps me awake, I would most likely be too tired to play games with her. Since then, she hasn't made a peep during the night. In the morning it's a different story. Does the fact that she can remember not to make sounds during the night indicate that she probably doesn't have dementia or Alzheimer's? What does it indicate, if anything at all?
