“Parkinson’s disease affects 10 million people worldwide, along with its symptoms, causes and treatments. Symptoms generally develop slowly over years. The progression of symptoms is often a bit different from one person to another due to the diversity of the disease. The cause remains largely unknown. Scientists believe a combination of genetic and environmental factors are the cause.  The first step to living well with Parkinson’s disease is to understand the disease and the progression.”
