She is 79, has Parkinsons and mobility issues. She has some very mild dementia. She gets alittle agitated when I ask her about the noises she is making. I've very convinced she isn't in pain. She usually makes these noises while she is going through her stuff or papers, etc. Anyone else had any similiar experiences? I haven't found anyone that can help with the explanation.....I don't want to try to stop her if it's emotionally soothing, and honestly I don't know if I could stop her. It can be very irritating since she will do if for quite awhile, but if there was a reason behind it, it would be less irritating.
