Major depressive disorder
Hi -- I'm afraid I'm going to revert the changes you made, and would like to explain why. This article, as a Featured Article, has been very careful to rigorously follow the "Medical Reliable Sources" policy, WP:MEDRS, which calls for use of secondary sources (meaning review articles) in preference to primary sources (meaning primary publications of data). Also the article has to be kept tightly under control in order to keep it from becoming too long. There is a related article, Biology of depression, where the material would be much more appropriate -- although even there it would be better to make use of secondary sources rather than giving your own interpretation of primary sources. The reason for preferring secondary sources over primary sources for medical articles is that for important topics so many primary sources usually exist, with such divergent messages, that experience shows it is impossible to maintain a coherent article if they are used. Regards, and please don't take this as discouragement. Looie496 (talk) 16:19, 10 June 2009 (UTC)
