Dear Barb and others Thanks for the welcome and for the reference sources. I subscribed to the list because my father (75) was recently diagnosed with Parkinson's disease and I would like to get hold of any information I can that might help him. He lives in Vancouver, BC, Canada and I am in Jamaica. I am particularly interested in any info about the genetic connection, because his sister (78) also has it and so did three of his six uncles.
