Larry's last updates did say something along those lines but there were lawyers involved, so maybe his wife was able to move him back permanently. If he was diagnosed officially with dementia, it would be very difficult for him to take back any sort of "control" on his own. To be honest, I'm surprised his lawyer did it that last time.
I just don't get that they took away his phone. My mother was suffering from dementia near the end of her life but I was still able to call her every day on her phone and talk to her. If they had taken away her phone, I would have given her another one.
