My mom is 86 with mid stage alzheimer's. Up until now, I have trusted her to be alone in a room for a few minutes with my 2 year old grand daughter. This morning, I went into her bedroom and my grand daughter had an open jar of vics rub and had it all over her hands. I told her that she shouldn't have given it to her and she said that "she just took it". Do Alzheimer patients have periods of common sense or do they just lose it? Obviously, I won't be leaving the two alone any more!
