MIL has always been an avid letter writer. It was her main mode of communication with out of state friends and family. She is now in the mid to end stage of dementia. When speaking with her she repeats herself constantly. We found out from some recipients of her letters that she also repeats whole sentences in her notes & letters. She also sends multiple letters to the same people, repeating her messages, almost word for word. She goes through a book of stamps every two weeks or less. We stopped buying rolls of stamps because she lost the first one the day after we purchased it. Anyway, I thought this was an interesting but none the less sad symptom of this disease.
