I have had a problem with drooling / excessive saliva, starting maybe 7 years ago. I was dx with PD four years ago. In the last 7-8 months my drooling has increased considerably in volume and frequency. I haven't seen much, if anything, posted on the list re: drooling. Is it a symptom of PD ? Can it be controlled? Thanks for any info. Bob Chapman, 65 age now /61 age dx /55 age onset
