My grandfather's Parkinson's was pretty far along by the time I knew him. I remember as a 4-year-old straining to understand his tremoring voice which — when combined with his thick Swedish accent — was almost impossible for me and my sister to understand. Even as a small child, I could tell it broke his heart.
In a study released last week, researchers explain exactly how pesticides can interact with the brain to trigger this incurable disease. Their findings may help prevent and treat Parkinson's for future generations.
