Poor Wolfy you are so deluded. You have never added anything of any use to the PD article. You don't even know basics. You're not a specialist. You're just a GP with all the ignorance that involves. You plainly don't keep up to date with PD because you keep on proving how dated your knowledge of it is. You keep on referring to some basic medical text. If it isn't in that book it isn't true according to you. I've read over 80 books on Parkinson's Disease. Even that isn't 5% of what I know. I spent over three years just on its biochemistry. What you know about PD biochemistry you could LITERALLY write on the back of a matchbox. As you have nothing useful to add you just revert everybody. You plainly suffer from intolerance, ignorance, conservatism and obsessions. You're detrimental to WP. So for good measure I've reverting dozens of your old edits - the ones you no longer check - just taking out the bits you added - all using different names of course.
