My grandmother has had Alzheimer's for a few years now and she forgets things in a matter of minutes. I take care of her at work, I noticed about a month ago that she can't sit still. she gets bored and will go through the desk or if she sees a box she'll get it, open it and put it back. she'll do this a few times. I tried stopping her once by asking nicely "what are you looking for? can I help?" she got angry, then when she did it again I asked her again and she said she didn't know what she was looking for. I put the TV on for her and she'll get bored. I was wondering if this is normal behavior or could she be stressed?
