Hi, all, Long before PD I read about a study where walking increased bone mass. I have osteoporosis as well as PD, starting my 6th yr. Three yrs ago I started treadmilling and exercising in water plus Evista and Cal-D. I have more bone mass now than I did 3 yrs ago. I can't take PD meds, but still do mile almost every day, hoping to grow some new brain cells. Was interested to find this work by Fred Gage at Salk Institute in La Jolla, CA, who my former student, now PD researcher Dr. Charleen Chu, oftens refers to. I have tremor, dystonia, bradykinesia, and micrographia, but am still driving, walking, taking care of myself, no PD meds. I started exercising when it was easier to do. Know it is hard to get anyone to exercise consistently, well or not, but felt maybe newly diagnosed PWP might want to consider this. Since I seem to be the only "exerciser" it was good to see some support for my approach, altho this article only mentions Alzheimers. If interersted take a look. http://www.the-scientist.com/yr2001/may/research2_010528.html [log in to unmask] ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
