IMHO, your mom and brother have said where to start........... Move him to where he can be helped and protect his assets..............
Parkinsons, in it's own right, is bad enough...... uncorrected hearing loss, diet, age all weigh on cognitive issues.
It sucks when the children have or need to become the parents, but that is often just the way it is.
YOU asked; '...So how do I approach this situation as the eldest son as delicately as possible without hurting him and his pride and what is the best course of action?...
HE is not being delicate, he is hurting others, if he is proud of his current conduct or he's always acted this way I would NOT worry about that either!
It's tough!!!
