My mother has had ALzheimers/dementia for approx 6 years and has been in a Nursing Home for 4 years. She was doing well and came to think of it as her little home as she had her own room to herself. But all of a sudden she started having falls (4 in two months) and was hospitalized twice now. While in the hospital she started having delusions at late evening. I thought she had gone back to sun downing but her doctor said as they progress dementia patients get delusional when they are confused or in different atmospheres then what they are used to. Has anyone had this experience with an Alzheimers/Dementia patient. What stage does this occur in?
