One cause of PD that has been questioned is the exposure to chemicals or pestisides. I am interested in an informal survey of prior occupation(s) of PD patients. My mother has PSP (progressive supranuclear palsy) which is a PD-plus and her friend has PD. Both were beauticians (yes, some exposure to chemicals and fumes). Her cousin has three family members with PD who all were farmers (exposure to pestisides). I would welcome ALL responses, explanations, suggestions regarding the issue of PD and occupation.
