She is 85 and I believe her to be in stage 6. She does this in cycles and seems to have really ramped up in the past 3 months. Is this a sign of going into stage 7? She walks with a walker but slow, shuffling gait. Has started patting herself some. She has a tremor and moves slowly. She doesn't recognize her children. She is up all night knocking at my bedroom door, very angry I am not up. Then she crys. I have to comfort her like a child, telling her she is ok and I love her but the sleep pattern is so hard.
