message: In the second sentence of your introductory paragraph, you write that patients with visual extinction can identify single objects presented to them briefly.  How briefly, and is the brevity of object presentation important in characterizing visual extinction?  If possible, specify a time scale both for presentation of multiple stimuli and single stimuli.
	You should also give specific examples of the “simple exercises” useful in treating symptoms of visual extinction in the “Prognosis” section.  The phrase “simple exercises” is quite vague and does not enhance understanding of the disorder.  Bergaa7 (talk) 02:13, 24 November 2009 (UTC)

message: Information in your history section and causes section seems to be contradictory. I would clarify whether visual extinction occurs mainly in the right hemisphere or in both equally. I found a paper that not only addresses this issue but also explores the possibility that visual extinction is due to restricted attention capacity. Given your claim in the society and culture section that, "Visual Extinction is often mistaken for attentional deficit," I suggest you read this article and strongly consider adding its findings. “What exactly is extinguished in unilateral visual extinction?

message: This is a great start guys. I have an idea of what visual extinction is and I had no clue what it could be before i read this.  Here are a few suggestions, hope they help!
*You might want to change visual area to occipital lobe at the beginning
*You should also link quite a few terms in here that confused me, such as:
**Afferent Inputs
**LLA--if you link it then you don't need the explanation of what it is
**Visual Neglect
**Attentional Deficit
**The experiment by Villeuminer and Rafal--if it isn't on wikipedia explain what it was or get rid of it because most people have no idea who they are or what the experiment was about
*What are simple stimuli properties? linkable? A short explanation would be helpful if you cant link it
*The first sentences of the causes and history sections are somewhat redundant
*Does anyone know why it remains stagnant versus getting worse in some cases? I looked on google and couldn't the answer.  Do you guys have that information or can you find it?
*You added an extra "work" in the last sentence of the first paragraph in the treatment section.
*The first sentence of the second paragraph in the treatment section is somewhat confusing and passive.  You may want to revise it
**Suggestion: There are other effective computer scanning methods that use specialized equipment designed specifically for scanning and cuing exercises that force patients to focus on multiple stimuli simultaneously.
*What is the range of 6 degrees of the angle of vision? I looked on google and couldn't find this either.  I don't have a clue what that means so i assume a lot of other people don't understand it either
*In the Culture and Society section you have a sentence about two visual stimuli being presented to a patient...etc.  I don't think it belongs in this section, but i do think it is a good piece of information.  You might want to put it into the introduction or the history section.
Besides that I like your article and I think you do a good job explaining what Visual Extinction is
