This is the inability to attend to more than a very limited area of the visual field despite normal visual fields. Typically patients can see individual objects but are unable to perceive a visual scene as a whole. There is often an associated inattention to the peripheries of the visual field.

Lesions which cause simultanagnosia are often bilateral posterior parietal and/or occipital.

Simultanagnosia is a component of Balint's syndrome.
