Former Nashville Predators coach Brent Peterson has released a book that details his diagnosis and surgery in his battle with Parkinson's disease.
His new book, "My Toughest Faceoff," is a mixture of Peterson's fight with the disease, hockey stories and his life in the sport.
"My wife and Jim Diamond, who wrote the book with me, it's in my words, but he helped me write it. He just said, 'You've got to do this,'" said Peterson sitting in Bridgestone Arena where he coached the Preds.
He continued, "So we started writing about the DBS and the surgery story and we started throwing in some hockey stories, ended up being a bunch of hockey stories and my whole life."
In 2011, Peterson underwent Deep Brain Stimulation, or DBS, which was a relatively new procedure for people with Parkinson's.
"DBS is deep brain stimulation and it's for Parkinson patients or people who have other things wrong with them," Peterson told Nashville's News 2.
"They put two holes in your head and put electrodes down in your head and blocks Parkinson's, then you have a battery pack here," he explained, pointing at his chest.
Peterson's invasive surgery was performed by doctors at Vanderbilt University Medical Center.
"It's really helped me. It's got me moving again. I can move my hands and I can move around and it's given me back my life. Right now I'd maybe be in a wheel chair. I was getting pretty bad there my last year when I was finishing up coaching," he recalled.
In 1978 he was drafted 12th overall by the Detroit Redwings. During the 1982-83 season for the Buffalo Sabres, Peterson scored 13 goals and 24 assists.
His playing career included stints with the Vancouver Canucks and Hartford Whalers.
Peterson accepted a job as associate head coach during the Preds first season in the league.
"I'm ticked off that I can't be a coach in the NHL. I want to coach, I want to do those things but I can't and it helps people recover and it helps people feel good about themselves when they see the things that I've gone through too."
