[Name] Dorsal Simultanagnosia [Description] 
Simultanagnosia broadly refers to the inability recognize more than one object at once. For example a patient with dorsal simultanagnosia may report seeing only one of four objects that are lined up in front of them. Individuals with dorsal simultanagnosia often use parts of an object to make inferences about an object as a whole. These individuals also have difficulty with reading and counting because it involves more than one object at a time. Dorsal simultanagnosia is commonly caused by bilateral damage to the bilateral parieto-occipito region.
