There seems to be more and more evidence that PD is sometimes hereditary. There have been genes discovered that definitely indicate a hereditary tendency - depends whether you have the gene. We don't always know.
A current study investigating this issue is the PROGENI study. Even though I have no known family history, I'm a participant. To learn more about this study, go to www.pdtrials.org and search on PROGENI. You can also go to this site for info on any pd study that you might be interested in or eligible to participate in.
Studies are a great thing. If we don't volunteer for em, how are we/others to learn, benefit, cure?!?
