Mom is almost 86 and has dementia. A month ago she had a seizure but scans showed no further damage. Since then she keeps her eyes shut all the time now, and prefers to blow her nose on her sleeves vs using a tissue, especially when she thinks no one is watching. Is this a normal progression of the dementia? She gets mad at me when I catch her and ask her to please use the tissue in front of her. Her hygiene and not wanting to shower went out the window a long time ago and I'm learning to understand that whole process, but this newest thing of blowing her nose on her clothing is perplexing me.
