Dad was diagnosed with early dementia in 2013. He has obsessive compulsive disorder, is a narcissist and is having severe memory problems. He has had multiple ER visits in the last 3 months, but is unwilling to follow doctor guidelines for nutrition and medication. He refuses help, but still expects me to come to his rescue when he feels ill. I have POA and am unsure if I should protect him from himself or let him self-destruct on his own terms.
