My MIL has recently begun accusing a lady in her suite (she lives alone in a AL suite) that she claims is stealing her things, wearing her clothes & jewelry, & taking her pictures off the wall. When asked if she could point this person out, she said she could and then pointed to herself in the mirror. Now she is afraid to leave her suite to go on outings or for meals because she says this lady will steal all her stuff. We have covered the mirrors but she uncovers them and the whole thing starts all over again. We've been told by the AL facility not to feed into her delusions. Is this the right thing to do? Is this a sign that she needs to move to memory care? What determines that memory care is needed?
