Alleged Iraqi weapons of mass destruction?

In a comment after a post titled Some People Will Believe Anything, about the Iranian president Ahmadinejad’s recent visit to Columbia University, blog author muzeuterpe claims:

I could give you the names and addresses of at 5 soldiers who were part of George W’s initial invasion who are suffering from neurological damage caused by the ‘non-existent’ chemical weapons.

A very startling claim, to say the least.

muzeuterpe, are you sure that your friends were injured by chemical weapons and not by bombs or depleted uranium? Bomb blasts can cause quite a bit of hidden neurological damage to people with no visible injuries.

Googling “neurological damage Iraq war” has led me to this news story, and a bunch of similar stories, about neurological damage from bomb blasts, not from chemical weapons. I also found some articles about the use of depleted uranium by the U.S. forces. The only article I found about neurological damage due to chemical weapons is this New York Times article, about veterans of the first Gulf War, not the most recent Iraq war. I then tried Googling “Iraq war neurological damage chemical weapons” and again found such reports pertaining only to the first Gulf war.
