Parkinson’s disease, a progressive movement disorder whose hallmark is damage to the dopamine-producing neurons in the brain, afflicts almost 12 million people worldwide. And the number of new cases is growing quickly. For roughly 13% of patients, genetics plays a key role. For many others, the underlying cause of the disease might be more mundane and insidious: environmental toxins — via the air we breathe, the water we drink, the food we eat and the chemicals with which we regularly come in contact. Neurologist Dr Michael Okun, co-author of The Parkinson’s Plan, joins CNN Chief Medical Correspondent Dr Sanjay Gupta to discuss where we stand today in our understanding of this disease, and the “PLAN” moving forward.
