Topographical agnosia patients are unable to use visual cues to guide them in a particular direction. Even though they may have excellent topographical memory that allows them describe the layout of their home, or the specifics of their workplace, they may not be able to navigate around their own home. Because they are unable to recognize the objects around them, this agnosia is categorized as an associative category. Topographical agnosia appears to be due to brain lesions in the right posterior cingulate area of the brain.
