Hi Mark,
I'm confident that my neurologist would be a sadistic, arrogant jerk no matter who paid his bill. I lived in the States for a number of years and met some great doctors and some that were a disgrace to their profession. In the end, any system is only as good as the people in it.
My problem is that I live in a remote area and don't have the same choice of specialists I'd have if I lived in or near a big urban centre like Toronto or Montreal.
That said, I read that only 1 in 20 Canadian brain injury patients get the rehabilitation services they need. Sadly, I don't think it's that much better anywhere else. Treating us is expensive, difficult and slow. In short, we're too much of a pain for any payment plan and most doctors.
