Dee: I fully agree with your national database idea. So many of the symptoms are common, it would be more efficient if we made a checklist of symptoms, with a space for "other" write ins. That would also make the data analysis easier. I researched Rich's symptoms on the Internet myself and diagnosed him (correctly) before bringing him to a neurologist to confirm my suspicions. Interestingly, the doctor didn't do all of the tests I had read about, and I prompted him to perform those tests before delivering his diagnoses. Wendy -----Original Message----- Hi Bill, I like your idea of making up a training document for MD's. My original idea was that we have a national database of all PD patients with a history of exposure to different chemicals, hereditary factors, head injuries, age of diagnosis, etc. Also would be included; a list of symptoms that were experienced prior to diagnosis: foot drop, lack of arm swing, depression/anxiety, loss of balance, pain, frequent urination, etc. My feelings are that if you get enough people to provide enough data that you will eventually begin to see some common denominators. Hopefully it would divulge experiences/lifestyle/events that a majority of people with PD share and thus would reflect a possible cause for PD. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
