Because being able to identify faces is a feature of memory, prosopagnosia has a link to other disorders that affect a similar region in the brain, including topographical disorientation, achromatopsia, and left hemianopsia. Topographical disorientation is when someone has difficulties identifying familiar landmarks and environments. Achromatopsia is total color blindness while left hemianopsia is the loss of vision on the left side of the vertical midline in each eye. All of these disorders occur due to damage to temporal and occipital lobe regions.
