Anton syndrome is best described as denial of blindness in the setting of lesions to which region?

Anton syndrome is a form of cortical blindness with anosognosia for vision—the person is blind because the visual cortex is damaged, yet denies being blind. This pattern arises most clearly when both occipital lobes are injured, so the brain cannot process visual information despite intact eyes. Bilateral occipital damage disrupts visual awareness while leaving some language and confabulation processes intact, which explains the denial of blindness. Frontal, temporal, and parietal damage produce other deficits—frontal lobe issues often affect judgment and insight for nonvisual problems; temporal lobe injury leads to visual recognition problems; parietal lobe damage can cause visuospatial neglect. None of these produce the characteristic denial of blindness seen with occipital cortex damage, which is why bilateral occipital lobe injury best fits Anton syndrome.
