My loved one has started leaning his forehead on the wall. It doesnt happen daily but more and more over the past few months he will shuffle to a wall and gently lean forward until his head is touching. Recently i watched him do this against a door and am obviously worried as anyone entering his room would surely have knocked him over. Has anyone else witnessed this behaviour? My mother in law says he would do it her as well. Walk to her and lean in u til their heads are touching.
