Formatting Agnosia Types List

Under the section "Types," visual agnosia has this description: "Visual agnosia is associated with lesions of the left occipital lobe and temporal lobes. Many are the inability to recognize objects. Subtypes:". Clearly "subtypes" is meant to refer to some of the types described below visual agnosia. However, the types listed are not organized in the manner this implies. For a short-term fix, I am considering deleting "Subtypes:" from the description of visual agnosia.

Well, "tactile agnosia" is treated almost the same way; "Tactile agnosia involve significant difficulty recognising physical feedback. Subtypes:". A decision should be made whether to categorize the different types depending on... sense affected? Or to let the list remain without any sub-categorization. The first option would be best served by reformatting the list to look more like an outline, whereas the second requires removal of the misleading "subtype:".

Fake.

Automobilia agnosia? Sounds fake to me. Could somebody provide a reference?

Alphabetize & citation needed

First, this list should be alphabetized. I looked for the above poster's Automobilia agnosia and then realized the thing wasn't alphabetized and although I can search for it, it'd be nice if people would not have to go to the trouble IMHO.

Then, I don't know how to add one of those 'citation needed' things to the article, but I believe there needs to be one for this entry: Prosopagnosia also known as faceblindness and facial agnosia: Patients cannot consciously recognize familiar faces, sometimes even including their own. This is often misperceived as an inability to remember names. Citation needed tag here? It is often misperceived as the inability to remember names? Who says? How do I know that this is true? (You know--I don't have to go through this--the whole purpose of citations.) I realize others need citations as well but this one just particularly bugs me for some reason. --70.59.146.117 (talk) 10:13, 16 March 2008 (UTC)[reply]

Translation

I think a more appropriate translation of agnosia would be "lack/absence of knowledge" since the Greek prefix a- means "without, not, lacking in" as in atheist, amoral, apathy. I know the term is translated as "loss of knowledge" e.g. in "Principles of Neural Science" by Kandel et al. but that doesn't make it right. — Preceding unsigned comment added by Howeworth (talk • contribs) 15:51, 18 August 2011 (UTC)[reply]

Agnosia for scenes?

Agnosia for scenes isn't here. I believe it isn't the same thing as topographical agnosia as described here, but I'm no expert. The issues described by Oliver Sacks in his book The Mind's Eye were I think labelled as topographical agnosia, but I'm not convinced was the same as the disorder described here. — Preceding unsigned comment added by 124.168.246.32 (talk) 03:01, 18 September 2011 (UTC)[reply]

Changes to the page

I will be making changes to the agnosia page in the upcoming weeks. I am doing this for a university assignment under the Association for Psychological Sciences initiative. The following are changes that I am planning to make based on reading previous comments on the talk page for the agnosia page:

I plan to provide a reference for automobilia agnosia, as it was noted that there is no reference for it. I plan on alphabetizing the list of all of the types of agnosia. I plan on creating a citation tag for prosopagnosia. I would also like to add topographical agnosia to the list.

Ideas of my own to improve the page are to add a section about patient DF who had a form of visual agnosia. Patient DF suffered from damage to lateral parts of the occipital lobe. She was unable to make copies of drawings or objects given to her, nor was she able to recognize the drawings or objects (Milner & Goodale, 1995). Interestingly, patient DF was able to successfully complete part of a card slot task (Allard, 2001) which I will expand upon in the section I add about patient DF.

Another section I would like to add to the agnosia page, is a section on Lissauer. Lissauer was one of the first theorists about agnosia (Vecera, 1998). This will provide a bit of background behind different theories about agnosia. Additionally I would like to add more information on the dorsal and ventral streams, as these play large roles in agnosia.

Lastly, I would like to add to the treatment and causes sections, as I believe they are sparse right now and adding information to them will increase the usefulness of the page on agnosia.

I may also add pictures showing different regions of the brain that are affected for certain forms of agnosia, specifically for appreceptive and associative agnosia. As well as diagrams showing both the dorsal and ventral streams. — Preceding unsigned comment added by Dpogorsk (talk • contribs) 19:47, 18 March 2012 (UTC)[reply]

Changes to Agnosia Completed

My changes to the agnosia page have now been completed. If anyone has any comments on the material that I have added or any more material that they believe should be added please comment on the talk page and I will be more than glad to take into account any comments.
