I can't be sure, however, he is increasingly having serious money problems. And when he talks when he is tired, he loses concentration rather more frequently and more profoundly. I don't know how else to describe it but its like he's lucid most days and it would SEEM like he's slowly losing his concentration/memory on some of these days and nights. He won't see the doctor because he couldn't pay for his tabs or insurance and won't let me take him, finding any excuse not to go. I have power of attorney, is this something I need to look into taking the reigns of somehow?
