Parkinson's disease is a progressive neurological disorder affecting the brain and nervous system.
"The news came as a massive shock to me," the former defender said in a statement released by the League Managers Association (LMA).
He added: "It has taken me time to feel ready to share my diagnosis, and I have found it difficult not being completely open with people.
"Personally, my passion and love for coaching is as strong as ever, I am focusing on keeping physically fit, which is key to slowing down the progression of Parkinson's.
