My dad was diagnosed with Parkinsons some 15 years ago. Definitely made some changes in his life, more so over the last couple of years. You can still lead a fairly normal life. Just gotta keep up with the meds and get them situated. They'll have to adjust the meds from time to time and it may take some trial and error to get them right. Start physical theropy now. The more you can build your body up now, the more you'll be able to do later. There are also a number of support groups around for parkinsons. You might look into a local one. Parents have found the one in their area to be real useful. They've gotten plenty of good info from other patients that doctors could never have told them. More along the lines of everyday living. If you have questions, feel free to PM me.
