The Parkinson’s Mystery

 and 
Around 2% of people over 65 develop Parkinson's disease, but its causes remain a mystery. One promising area of research is focusing on environmental and occupational exposure to pesticides, heavy metals, and solvents, which may combine with a genetic predisposition to the disease.

JOHANNESBURG – Parkinson’s disease is a degenerative neurological disorder that affects around seven million people globally, and one million in the United States alone, usually afflicting people older than 50. The disease strikes 2% of those over age 65, and 5-10% of cases occur in people under 50. The cause remains unknown, preventing us from arresting the disease’s development – though environmental and occupational factors loom large in recent research.
