My mother recently moved in with us and I've noticed that she unconsciously gathers her pant leg and rolls the fabric while we are having a normal conversation. She also often changes history when relating memories of people, places & events from the past. The changes often present her in the best light possible rather than what actually happened. Otherwise she is mostly the same difficult, snide and controlling mother she has always been but with less energy. I am wondering if others have seen these new behaviors and are they something I should be concerned about?
