My aunt is in memory care and since the doctor upped her namenda she has been very agitated. She has always just cat napped but now she is constantly moving, taking things from other residents rooms, eating constantly, putting feces everywhere, putting stuff in toilets. I'm afraid for her. She needs sleep and some peace. Can the increase in namenda cause this? Will adding Seroquel help her to calm down? She's acting manic. Any insight would be helpful.
