Talk:Progress and Prospects in Parkinson's Research/Causes
I have removed the 'signature' of Reverett123 because this is recorded in the History of the page and so is not necessary. I appreciate that it might indicate some hesitation about adding this entry. But it is OK and the history tab shows who has done what. If you want to discuss what you are thinking of doing, you can do so on this Talk page.
There also needs to be a citation as to where evidence for this claim is to be found in the same way as other parts of this page are backed up. Is there a review that can be referenced or quoted? The statement as you have entered it is also a little unclear in its meaning; can you put a little more flesh on it? (But not too much because a full exposition would go on a separate subpage like the other subpages.
