Apparently my Mother and Father decided to keep my Dad's Disease a secret.  That was the wrong thing to do.  If you have a loved one diagnosed with any of the dementia diseases you should tell everyone involved with the person, (and even complete strangers) so that we can better handle the situation.  I kept hearing that my Dad was having small altercations with different sales people.  I thought that strange.  I had never heard of him having problems before with anyone.
