I am in my early 50s but had this problem since my 20s especially in the spring and summer months. After touching or breathing fumes from an herbicide, I get Parkinson like symptoms that usually last a day or so. Except this year, it has taken more time to recover. Do people who get Parkinson like symptoms for short time periods from an exposure from a poison develop full blown Parkinson later in life? If exposure from a poison is now including cognitive problems as well as the motor skill problems how concern should I be? Who can help me with this problem? I am scared that one day, I wonâ??t recover and be stuck in a condition where I cannot walk or think or perform simple task.
