I saw that. The patient felt as if his PD was almost gone. He looked so relaxed and content; it was great! The doctor said they were only allowed to work on one side of the brain, in case there was a bad outcome. Some people's positive results didn't last though, and they're looking into why.

The patient said he had to wait 6 months to see the benefit of the procedure. But he feels great, four years later.

Just noticed that the video is on the ABC page. It's worth watching.
