My husband is 94 years old and has severe dementia. I am caring for him at home.I'm 75 years old. We have been married 52 years. My husband is constantly asking about his Dad. I tell him he is fishing in Florida. He keeps demanding that I get him touch with his older brother. My husband is the last living member of his immediate family. I am at my wits end. He just now was pounding on the TV screen wanting Andy Griffith to assist him. Help!!!!!!!
