His dementia is rapidly progressing. He refused to give up control. I believe nanny cams inside and security cameras outside would be most helpful when I go food shopping. Needless to say he feels that there are people waiting to break in so he stays awake all night and waits for them. That is only one issue I am having. He won't allow anyone to come in and help, and wants to stay in his own home. Any help would be most appreciated.
