Dad was diagnosed with dementia about 4 months ago, he is becoming very hateful to my Mom and very paranoid about everyone. He wants to move out, but he tried that before and couldnt medicate himself and ended up in the hospital. The family tries to help, but he puts on an act when we're there, then turns angry when we leave. How can I make life more bearable for my Mom? He will not allow another person to come in and help, as a caregiver. He still works on his farm, but is constantly breaking his equipment.
