Healthline.com has come out with a list of their pick of the top 15 blogs for Parkinson's disease, 2012. I would highly recommend you take the time to look through these sites. They are all, without exception, great blogs.
I found a new favorite amongst them:
Sitting Comfortably? This is the blog of Andy Daly: artist, teacher, photographer, swimmer, cyclist, and Tae Kwon Do black belt. He has Parkinson's, too.
There are other familiar sites from Kate Kelsall (Shake, Rattle, and Roll), Bibmomma, and Dirtybutter, and of course, Bob Kuhn's "Positively Parkinson's".
In case you didn't know, Bob has been traveling around the world to collect stories about Parkinson's disease. I was also reminded of Peter Dunlap-Shohl's blog, "Off and On", from Alaska. Peter is a cartoonist.
There's more, of course. Studio Foxhoven even got in there! After you look at the list and peruse the websites, go back and look through Healthline's website. I've used this site as a reference any number of times.
