I share your frustration with the snail's pace of publishing results. I hate to turn cynical, maybe it's all just too complex to figure out, but it sure is frustrating. When I was first diagnosed over 5 years ago, I saw so many hopeful-sounding news (creatine, inosine, COQ10, Isradipine, rasagiline, cogane, stem cells, estrogen, coffee, smoking, etc), and my neuro actually said "within 10 years," but nothing ever seems to come of any of it. Someone in my PD Chorus wrote a song about it called Just Ten More Years, set to the tune of I'll Fly Away! Very funny lyrics. What can you do but laugh sometimes?
