It is estimated that four to six million people around the world suffer from Parkinson's disease - around 80,000 of these are in Australia. After Alzheimer's, Parkinson's is the most common neurodegenerative disease and the number of people with Parkinson's disease in 15 of the world's largest nations will double over the next generation, according to a study published in the journal Neurology in 2007. Living with Parkinson's is written by medical journalist Gabriella Rogers and is endorsed by Parkinson's Australia, bringing together a formal medical perspective with the more personal perspective to provide a comprehensive look at the disease from all angles.
